intro

Tart, juicy fresh raspberries and rich dark chocolate chunks dot these tender, moist muffins—a perfectly balanced sweet summer treat.

Ingredients

All-purpose flour 248 grams (2 cups + 1 tablespoon)
Granulated sugar 100 grams (1/2 cup)
Baking powder 8 grams (2 teaspoons)
Fine sea salt 3 grams (1/2 teaspoon)
Baking soda 1 gram (1/4 teaspoon)
Unsalted butter 57 grams (4 tablespoons / 1/4 cup, melted and cooled)
Whole milk 180 ml (3/4 cup, room temperature)
Large egg 50 grams (1 unit, room temperature)
Pure vanilla extract 5 ml (1 teaspoon)
Fresh raspberries 150 grams (1 1/4 cups, patted dry)
70% dark chocolate chunks 110 grams (2/3 cup, chopped into 1cm pieces)

Steps

1

Prep oven and muffin tin

Preheat your oven to 190°C (375°F) with a rack positioned in the middle. Line a 12-cup standard muffin tin with paper baking liners, or lightly coat each cup with nonstick cooking spray to ensure easy release after baking.

Step 1
step1：Prep oven and muffin tin
2

Whisk dry ingredients

In a large glass mixing bowl, combine 240 grams (2 cups) of the all-purpose flour, 100 grams granulated sugar, 8 grams (2 teaspoons) baking powder, 1 gram (1/4 teaspoon) baking soda, and 3 grams (1/2 teaspoon) fine sea salt. Whisk vigorously for 30 seconds to evenly distribute leaveners and eliminate any small clumps.

Step 2
step2：Whisk dry ingredients
3

Combine wet ingredients

In a separate medium ceramic bowl, whisk together the cooled melted 57 grams (1/4 cup) unsalted butter, 180 ml (3/4 cup) room-temperature whole milk, 1 room-temperature large egg, and 5 ml (1 teaspoon) pure vanilla extract. Mix for 20 seconds until completely smooth, with no streaks of unincorporated egg visible.

Step 3
step3：Combine wet ingredients
4

Fold batter and add-ins

Pour the entire wet mixture into the bowl of dry ingredients. Use a rubber spatula to fold gently only 8-10 times, until just combined—lumps in the batter are expected and desirable, as overmixing creates tough muffins. Toss 150 grams patted-dry fresh raspberries and 110 grams chopped 70% dark chocolate chunks with the remaining 8 grams (1 tablespoon) all-purpose flour, then fold into the batter in 2-3 light turns, taking care not to crush the raspberries.

Step 4
step4：Fold batter and add-ins
5

Portion batter into tins

Use a 45 ml (3-tablespoon) spring-loaded cookie scoop to divide the batter evenly between the 12 prepared muffin cups, filling each liner exactly 2/3 full. Do not overfill cups, as the leaveners will cause muffins to rise and spill over the tin edges while baking.

Step 5
step5：Portion batter into tins
6

Bake until golden

Place the filled muffin tin on the middle oven rack and bake for 18-20 minutes at 190°C (375°F). Test doneness by inserting a wooden toothpick into the center of a middle muffin: it should come out with 1-2 moist crumbs attached (not wet batter), and muffin tops will be domed and light golden brown.

Step 6
step6：Bake until golden
7

Cool before serving

Remove the tin from the oven and let muffins rest in the tin for 5 minutes at room temperature, then transfer each muffin to a wire cooling rack for an additional 10 minutes. Serve slightly warm for soft, melty chocolate and bright, juicy raspberry flavor.

Step 7
step7：Cool before serving

Tips

1.Coating raspberries and chocolate chunks in a thin layer of flour before folding into batter prevents heavy add-ins from sinking to the bottom of the muffins during baking.
2.Never overmix muffin batter: overworking the flour develops gluten, which results in dense, tough muffins instead of light, tender crumb; visible lumps in the mixed batter are completely normal.
3.If substituting frozen raspberries for fresh, do not thaw them before adding to the batter—thawed berries release excess juice that will turn batter soggy and discolored.

Raspberry Dark Chocolate Muffin:Frequently Asked Questions

1.Can I use frozen raspberries instead of fresh for these muffins? ▾
Absolutely! Swap fresh raspberries for frozen straight from the freezer—don’t thaw them first, as that releases excess juice that makes muffins soggy and streaks the batter purple. Toss frozen berries in 1 teaspoon of all-purpose flour before folding in to keep them from sinking, and add 2 to 3 minutes to your total bake time.
2.What cacao percentage is best for the dark chocolate in these muffins? ▾
Stick to 60-70% cacao dark chocolate for the best balance. Anything higher (80%+) can taste overly bitter against the sweet, tart raspberries, while milk chocolate will make the muffins too cloying. Chop a bar into rough, uneven chunks for varied, gooeier chocolate pockets in every bite.
3.Why do my raspberries always sink to the bottom of the muffins? ▾
Sinking berries usually stem from two issues: an overly thin batter, or berries that are extra wet and heavy. Pat fresh raspberries very gently with a paper towel to remove surface moisture before adding, toss them in a light flour dusting, and don’t over-mix your batter to keep it thick enough to hold berries in place.
4.Can I make these muffins gluten-free? ▾
You can easily make these gluten-free by swapping the all-purpose flour for a 1:1 gluten-free baking blend that contains xanthan gum. Avoid using single gluten-free flours like almond or coconut flour alone, as those will create a dense, crumbly texture that doesn’t match the original tender, moist crumb.
5.How do I keep these muffins moist instead of dry and crumbly? ▾
Dry muffins almost always come from over-mixing the batter or over-baking. Mix wet and dry ingredients only until just combined—lumps are totally fine, as over-stirring develops tough gluten. Bake at 375°F, and start checking for doneness at 18 minutes, pulling them when a toothpick has a few moist crumbs attached.
6.Can I reduce the amount of granulated sugar in this recipe? ▾
You can cut the granulated sugar by up to 25% (about ¼ cup for a standard 12-muffin batch) without ruining texture, since dark chocolate and ripe raspberries add plenty of flavor. Don’t cut more than that, though—sugar doesn’t just sweeten, it locks in moisture and creates that signature soft, tender crumb.
7.Do I need to use paper liners in my muffin tin for this recipe? ▾
Paper liners make cleanup a breeze and prevent sticking, but they’re not required. If you skip liners, grease every cup of your muffin tin thoroughly with softened butter or nonstick baking spray, coating the top rim too, since muffins rise and spread slightly as they bake. Let muffins cool 5 minutes in the tin before popping out.
8.Why do my muffins turn out with flat, dense tops instead of nice domes? ▾
Flat, dense tops usually stem from old, expired leavening (baking powder or baking soda) or an oven that runs too cool. Test your leaveners first: baking powder fizzes in hot water, baking soda in hot vinegar. Bake at 375°F for the first 10 minutes to trigger a fast rise, then drop to 350°F to set the crumb.
9.Can I add extra mix-ins like nuts or crunchy toppings? ▾
Absolutely! Chopped toasted walnuts or slivered almonds pair beautifully with raspberry and dark chocolate—add up to ½ cup, folded in with the berries and chocolate. You can also sprinkle 2 tablespoons of rolled oats mixed with a teaspoon of sugar over muffin tops before baking for a cozy, crunchy, bakery-style finish.
10.How should I store leftover muffins to keep them fresh? ▾
Store fully cooled muffins in an airtight container at room temperature for up to 3 days. Place a paper towel in the bottom of the container to absorb excess moisture from the raspberries, which prevents soggy bottoms. Avoid storing them in the fridge, as cold, dry air makes muffins go stale much faster.
11.Can I freeze these muffins to enjoy later? ▾
These muffins freeze beautifully! Let them cool completely, then wrap each individual muffin tightly in plastic wrap and tuck them into a labeled freezer bag for up to 3 months. Thaw at room temperature for 1 to 2 hours, or warm for 20 seconds in the microwave for a quick, fresh-tasting treat.
12.Can I use pre-made dark chocolate chips instead of chopping a chocolate bar? ▾
You can, but chopped chocolate bars give a far better texture. Pre-made chips have added stabilizers that help them hold their shape, so they won’t melt into gooey, rich pockets the way chopped bar chocolate does. If you do use chips, stick to regular-sized (not mini) dark chocolate chips in the same measured amount.
13.Can I adjust this recipe to make vegan raspberry dark chocolate muffins? ▾
You can make a tasty vegan version with a few simple swaps: use one flax egg (1 tablespoon ground flax mixed with 3 tablespoons water, left to thicken 5 minutes) per egg called for, swap dairy butter for melted coconut oil, and use dairy-free dark chocolate with no added milk solids. The tender crumb and flavor hold up perfectly.
14.Why does my batter turn purple when I fold in the raspberries? ▾
Light purple streaks in the batter are totally normal, and happen when delicate raspberry skins break and release their bright juice as you fold. To minimize deep purple discoloration, fold raspberries in very gently at the very end of mixing, and don’t over-stir. A few light streaks won’t impact the flavor of your finished muffins at all.
15.Can I make these as mini muffins instead of full-sized? ▾
Absolutely! This recipe works beautifully for mini muffins, which are perfect for kid snacks or brunch spreads. Grease a mini muffin tin well, fill each cup ¾ full, and bake at 375°F for 10 to 12 minutes, checking for doneness with a toothpick the same way you would for full-sized muffins.
16.Do I need to sift my dry ingredients for this muffin recipe? ▾
You don’t need to sift, but it’s a quick step that creates a lighter, more even crumb. If you skip sifting, be sure to whisk the flour, baking powder, baking soda, and salt together really well in a separate bowl before adding to wet ingredients. This prevents clumps of leavening that can create bitter, uneven air pockets in baked muffins.

OMG these raspberry dark chocolate muffins are a GAME CHANGER for my weekday breakfast meal prep! I baked a batch on Sunday and they stayed moist all week, my 7 and 9 year old beg for them every morning before school. Did anyone try swapping the raspberries for frozen ones? I only have a big bag from Costco right now!

yesterday

I used frozen raspberries last week! Just toss them in a little flour before folding them in so they don’t sink and turn the whole batter pink, works perfectly!

yesterday

Great tip from Kate! Frozen raspberries work beautifully here – the flour trick is key to prevent sinking, no need to thaw them first either!

3 days ago

Brought these to my office potluck yesterday and they were gone in 10 minutes flat! The balance of tart raspberry and rich dark chocolate is chef’s kiss, not too sweet at all. Only thing is my muffins stuck a little to the paper liners, any advice for next time?

2 days ago

I had that issue my first batch too! I switched to lightly greasing the liners with nonstick spray and it fixed it totally, zero sticking now.

2 days ago

So glad they were a hit at the potluck! Greasing liners works great, or you can also let the muffins cool completely in the tin for 10 minutes before transferring them to a rack – that helps them release easier too.

1 week ago

Wait, has anyone tested this recipe with a 1:1 gluten free all purpose flour? I have a celiac teen and we’re always hunting for easy baked goods that don’t taste like cardboard. These look too good to pass up!

5 days ago

I made them with Bob’s Red Mill 1:1 GF flour last weekend and my non-GF husband couldn’t tell the difference! Just added an extra tablespoon of oat milk to get the batter consistency right, came out so fluffy.

3 days ago

Thanks for sharing your GF swap! We’ve tested this with 1:1 GF flour blends with great success – the extra splash of milk is a perfect adjustment if your batter feels too thick.

5 days ago

SO good. I used 70% cacao dark chocolate chunks instead of chips and it made these taste like something from a fancy bakery, not a homemade weekday muffin. My roommate ate three as soon as they came out of the oven, lmao. How long do these stay good stored on the counter?

3 days ago

I keep mine in an airtight container on the counter for up to 4 days and they’re still perfect! I pop mine in the microwave for 10 seconds to get the chocolate all melty again, chef’s kiss.

2 days ago

Love the 70% cacao swap, that’s our favorite way to make them too! Stored airtight at room temp they’ll last 3-4 days, or you can freeze them for up to 3 months for quick snacks.

Tried these for my daughter’s soccer team snack this weekend, huge hit! The only note I have is that my cook time was closer to 28 minutes instead of 35, though I know my oven runs a little hot. Do you recommend using light or dark metal muffin tins for this recipe?

5 days ago

I use a light colored tin and mine took exactly 35 minutes like the recipe says! My sister uses a dark nonstick tin and hers were done at 30, so that definitely matches what you noticed about cook time differences.

5 days ago

Thanks for the note on cook time! Oven and tin color make such a big difference. We test on light metal tins, so if you’re using dark nonstick, start checking for doneness 5-7 minutes early to avoid overbaking.

Wait, is there a way to cut back on the sugar a little? I love the raspberry and dark chocolate flavor combo but I find most muffin recipes are way too sweet for my taste, especially with the chocolate already in there. I don’t want to mess up the moist texture though!

1 week ago

I cut the granulated sugar by 1/4 cup last time I made these and they were perfect! The raspberries add so much natural sweetness, I didn’t miss the extra sugar at all, texture was still super moist.

1 week ago

Great question! You can absolutely reduce the granulated sugar by 2-3 tablespoons without impacting texture, and the natural sweetness from the raspberries and dark chocolate will still shine through.

yesterday

Made these last night for my book club and everyone asked for the recipe! I added a little lemon zest to the batter to amp up the raspberry flavor and it was such a good call. 10/10, will be making these monthly for sure.

2 hours ago

The lemon zest addition sounds incredible! That bright citrus note pairs so perfectly with tart raspberries and rich chocolate, we might have to test that variation ourselves!

5 days ago

Super easy recipe even for someone who burns toast half the time, lmao. I didn’t have fresh raspberries so I swirled raspberry jam on top and it still slapped. 10/10, no notes, will make again once my RA lets me use the dorm oven again after I set off the smoke detector making popcorn.

3 days ago

Wait the jam swirl idea is genius! I’m stealing that for my next batch, I never have fresh fruit on hand in the dorm either, this is perfect.

3 days ago

My kids are so picky about muffins and they devoured these! I love that the recipe is easy enough to throw together on a school morning, no fancy ingredients required. The dark chocolate doesn’t make a mess in their backpacks either, which is a total win for me.

2 days ago

That makes us so happy to hear! We love easy, low-mess recipes that work for busy school mornings, so thrilled your picky eaters approved.

30 minutes ago

These are the perfect pairing for my morning latte! Not overly sweet, moist, the little bursts of raspberry are so good. I added a sprinkle of turbinado sugar on top for crunch and it was *chef’s kiss*. Highly recommend!

5 minutes ago

The turbinado sugar top is my favorite part too! It adds that little crispy sweet bite that makes these feel way more fancy than they are, right?

2 weeks ago

First time baking muffins from scratch and these came out perfect! I was so nervous I’d overmix the batter but the recipe instructions were super clear, no dense rubbery muffins here. Even my partner who hates fruit in baked goods loved these.

1 week ago

Way to go on your first scratch muffin batch! Overmixing is the #1 mistake new bakers make, so awesome that you nailed it first try – we’re even impressed your fruit-in-baked-goods hating partner was a fan!

1 week ago

Made these as a post-workout snack, swapped half the flour for whole wheat, used Greek yogurt instead of sour cream, and they were still so moist and tasty! Great way to get a little sweet fix without derailing my nutrition goals.

5 days ago

Thanks for the swaps! I’ve been looking for lighter muffin recipes to make for my hike snacks, I’m definitely trying the whole wheat + Greek yogurt version this weekend.

2 days ago

Wait, can I use milk chocolate instead of dark? My kid thinks dark chocolate is “too bitter” but he loves raspberry and muffins, so I don’t want to skip making these just because of the chocolate type!

yesterday

Absolutely! Milk chocolate works perfectly here, the swap is totally seamless. You can even use semi-sweet if that’s what you have on hand, it’ll still be delicious.

5 days ago

Added these to my weekend brunch spread last Sunday alongside eggs, bacon, and fruit salad, and guests were raving about them nonstop. The tart raspberry cuts through all the rich brunch food so well, 10/10 will be a permanent brunch menu item from now on.

1 week ago

Froze a batch of these for my teen’s after school snacks and they thaw perfectly in 30 seconds in the microwave. Way better than the processed granola bars we used to buy, and I know exactly what’s in them. SO good.

2 weeks ago

Full transparency, I forgot to add the baking powder the first time I made these and they still somehow tasted amazing? Lmao, obviously they were a little flat but the flavor was so good I didn’t even care. Made them correctly the second time and they were perfectly fluffy, duh. Even my sad flat first batch got devoured by my roommates in 24 hours, so that says something.

3 days ago

Made these vegan by swapping the egg for a flax egg and using oat milk, they came out so fluffy and delicious! My non-vegan friends didn’t even notice they weren’t the regular version, total win. Will be making these again for my next potluck.

just now

Baked these on a rainy Saturday afternoon when I was stuck inside, and the whole house smelled amazing for hours. The warm melted dark chocolate with the bright raspberry is the coziest combo ever, exactly what I needed. 10/10, no notes.
