intro

Soft, warmly spiced tender muffins packed with chewy rolled oats and plump raisins, perfect for quick breakfasts, afternoon snacks, or group gatherings.

Ingredients

Old-fashioned rolled oats 1.5 cups (135g)
Raisins ¾ cup (110g)
All-purpose flour 1 cup (120g)
Packed light brown sugar ⅔ cup (135g)
Baking powder 1.5 teaspoons
Baking soda ½ teaspoon
Ground cinnamon 1 teaspoon
Fine table salt ½ teaspoon
Whole milk (room temperature) 1 cup (240ml)
Unsalted butter (melted, cooled) 6 tablespoons (85g)
Large egg (room temperature) 1 unit (50g)
Pure vanilla extract 1 teaspoon

Steps

1

Prep oven and soak oats

Preheat your oven to 400°F (200°C), then line a 12-cup standard muffin tin with paper liners or lightly grease each cup with butter. In a medium mixing bowl, combine 1.5 cups rolled oats with 1 cup room-temperature whole milk, stir to fully coat all oats, and let rest 10 minutes to soften.

2

Whisk dry ingredients

In a separate large mixing bowl, whisk together 1 cup all-purpose flour, ⅔ cup packed light brown sugar, 1.5 teaspoons baking powder, ½ teaspoon baking soda, 1 teaspoon ground cinnamon, and ½ teaspoon fine table salt until fully blended, breaking up any brown sugar clumps with the whisk.

Step 2
step2:Whisk dry ingredients
3

Blend wet oat base

After the oats have soaked for 10 minutes, add 6 tablespoons cooled melted unsalted butter, 1 room-temperature large egg, and 1 teaspoon vanilla extract to the oat-milk mixture. Stir with a wooden spoon until the egg is fully incorporated, with no yellow streaks remaining.

Step 3
step3:Blend wet oat base
4

Fold batter and raisins

Pour the wet oat mixture into the large bowl of dry ingredients, then add ¾ cup raisins. Fold gently with a silicone spatula only until no dry flour streaks remain; do not overmix, as this creates tough muffins. The finished batter will be thick and slightly lumpy.

Step 4
step4:Fold batter and raisins
5

Portion batter into tin

Scoop batter evenly into the prepared muffin tin, filling each paper liner exactly ⅔ full (about ¼ cup batter per cup) to leave space for rising. Tap the tin firmly on the counter 2-3 times to pop any large trapped air bubbles.

Step 5
step5:Portion batter into tin
6

Bake and cool muffins

Bake in the preheated 400°F (200°C) oven for 18-20 minutes, until a toothpick inserted into a center muffin comes out with 1-2 moist crumbs attached (no wet batter). Let muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool 10 minutes before serving.

Step 6
step6:Bake and cool muffins

Tips

1.Avoid overmixing the batter after combining wet and dry ingredients: lumps are normal, and overstirring develops excess gluten that leads to tough, dense muffins instead of tender ones.
2.Use room-temperature milk and egg for the smoothest batter; cold ingredients cause melted butter to solidify into clumps, creating uneven, greasy spots in finished muffins.
3.For plump, juicy raisins instead of hard, dry bits, soak raisins in hot tap water for 5 minutes and pat fully dry with paper towels before folding into the batter.

Oatmeal Raisin Muffin:Frequently Asked Questions

1.Can I use instant oats instead of old-fashioned rolled oats in this recipe?
You can, but note that instant oats are cut much finer, so your muffins will have a softer, less distinct chewy oat texture. If you substitute, use 2 tablespoons less instant oats per cup of old-fashioned oats called for, and avoid overmixing to prevent gummy results. Skip steel-cut oats here—they stay too tough without pre-soaking.
2.My raisins always sink to the bottom of my muffins—how do I prevent that?
Toss your raisins in 1 teaspoon of the measured all-purpose flour from the recipe before folding them into the batter. The light flour coating creates friction that keeps raisins suspended as the muffins bake, instead of sinking straight to the liner. Fresh baking powder also helps, as it makes the batter set fast once it hits the hot oven.
3.Can I swap the packed light brown sugar for regular white granulated sugar?
You can, but you’ll lose that warm, subtle molasses flavor that makes these classic muffins taste so cozy. If you do swap, use the same volume of granulated sugar plus 1 tablespoon of mild molasses per cup of sugar to mimic light brown sugar’s depth. Without that add-in, your muffins will be paler, slightly drier, and less flavorful.
4.How do I make sure my muffins turn out soft and tender instead of dense and tough?
The number one rule is to never overmix your muffin batter! Stir wet and dry ingredients only until just combined—small lumps are totally fine. Overmixing develops gluten in the all-purpose flour that leads to tough, chewy results. Also, confirm your baking powder is less than 6 months old, as expired leavening won’t create a light, fluffy rise.
5.Do I need to soak raisins before adding them to the muffin batter?
It’s not required, but soaking raisins for 10 minutes in warm water, apple juice, or a splash of vanilla will plump them up extra so they stay juicy instead of drying out during baking. Just drain them really well and pat lightly with a paper towel before tossing in flour, so extra moisture doesn’t make your muffins soggy.
6.Can I make these oatmeal raisin muffins ahead for weekly meal prep?
Absolutely! These muffins hold up beautifully for quick grab-and-go breakfasts. Let them cool completely after baking, then store in an airtight container at room temperature for up to 3 days, or freeze individually wrapped for up to 3 months. Thaw at room temp for 30 minutes, or warm 15 seconds in the microwave for that fresh-baked taste.
7.Why didn’t my muffins rise properly even though I added baking powder?
The most common culprit is expired baking powder—test it by dropping a teaspoon into a cup of hot water; if it doesn’t fizz immediately, it’s too old to work. Other common issues are overmixing the batter, filling liners less than ⅔ full, or opening the oven door before 12 minutes of bake time, which can cause rising muffins to collapse.
8.Can I add extra mix-ins like nuts or cinnamon chips to this base recipe?
Of course! This classic base is super flexible. Fold in up to ½ cup of chopped walnuts, pecans, cinnamon chips, or dried cranberries along with the raisins for extra texture and flavor. Just stick to a 1-cup maximum of total add-ins so you don’t weigh down the batter, which would prevent a good rise and lead to dense muffins.
9.Do I have to use paper muffin liners, or can I grease the tin directly?
You don’t need liners at all if you don’t have them on hand! Just generously grease each muffin well with softened butter, nonstick spray, or a light dusting of flour to prevent sticking. Liners make cleanup easier for group gatherings, but greasing the tin directly gives you slightly crispier muffin edges, which many bakers prefer.
10.What’s the best way to tell when these muffins are fully done baking?
Bake these at 375°F (190°C) for 18 to 22 minutes for the best tall rise and tender crumb. Test for doneness by inserting a toothpick into the center of a middle muffin: it should come out with 1 to 2 moist crumbs attached, not wet batter. Let them rest in the tin for 5 minutes before moving to a rack to cool, so they don’t fall apart.

OMG these are SO good! I baked a batch on Sunday for meal prep breakfasts this week and they’ve held up perfectly in the fridge. Not too sweet, super moist, the oats give such a nice chewy texture. My roommate keeps stealing them off the counter lmao

yesterday

My kids LOVED these! I packed one in each of their lunch boxes yesterday and they all asked for seconds when they got home. I did swap half the raisins for mini chocolate chips for my youngest who swears he hates raisins, and even that version turned out amazing. So easy to throw together on a school night too!

2 hours ago

So glad the whole family enjoyed them! The mini chocolate chip swap is such a kid-friendly hack, I’ll have to try that next time I make these for my niece’s soccer snack day.

Took these on a day hike in the Rockies last weekend and they were the perfect trail snack! Filling, not crumbly, didn’t get squished in my pack. Only note is I added a dash of extra cinnamon because I’m obsessed with cinnamon, would recommend.

yesterday

Total game changer adding extra cinnamon! I did that too after seeing your comment and it made the whole kitchen smell like fall, 10/10 tip.

Really solid muffin recipe! Super easy to follow even with my tiny apartment oven that runs hot. Only reason it’s not 5 stars is I found them a tiny bit dry on day 3, but warming them up for 10 seconds in the microwave with a little butter fixed that right up. Will definitely make again.

Brought these to my church potluck last Sunday and they were gone in 10 minutes! Multiple people asked me for the recipe, I told them it’s this exact one with no tweaks needed. Wait — has anyone tried making these with golden raisins instead of regular? I have a giant bag I need to use up.

3 days ago

I used golden raisins last time I made them! They’re a little sweeter and softer, worked perfectly, no changes to the recipe needed at all.

2 days ago

Great question! Golden raisins work beautifully in these, as do dried cranberries if you ever want to mix things up. So happy they were a potluck hit!

As someone who can barely make toast without burning it, I was shocked how easy these were! 35 minutes total, no fancy equipment, just a bowl and a muffin tin. Total win for my dorm meal plan slump. I used cheap generic oats and raisins from the campus grocery store and they still slapped.

1 week ago

Love that! This recipe is designed to be super forgiving, even for beginner bakers, so I’m thrilled it worked out for you in a dorm kitchen. No fancy ingredients required at all.

I was really excited for these but I had to swap in gluten-free all purpose flour and oat flour since I have celiac, and they came out a little denser than I expected. Flavor was great though! Maybe I needed to add a little extra milk? Not sure, might tweak next time.

Made these for my daughter’s soccer team breakfast before an early game and the other parents were raving. I added a tiny bit of vanilla glaze on top for a little extra sweetness, and it paired so well with the oat and raisin base. Will be making these a regular weekend bake for sure.

30 minutes ago

Wait the vanilla glaze idea is genius! I’m making these for my son’s team next weekend, did you just do powdered sugar + a little milk + vanilla?

5 minutes ago

Yep that’s exactly it! 1 cup powdered sugar, 2 tbsp milk, 1 tsp vanilla, drizzled over the top once the muffins are totally cool. Super easy!

These freeze SO well! I made a double batch, popped half in the freezer, and when I want one I just microwave it for 45 seconds and it tastes exactly like it just came out of the oven. Perfect for busy work mornings when I don’t have time to make breakfast.

5 days ago

Thank you for the freeze tip! I always end up throwing out half a batch of baked goods because I can’t eat them fast enough, can’t wait to try freezing these next time.

Full transparency: I hate raisins. My wife made these last night and I ate two without even realizing they had raisins? They’re that good. The oats keep them hearty, the sweetness is just right, I don’t know what kind of wizardry this is but I’m a convert. Wait no, I still hate raisins in cookies, but in these? *Chef’s kiss*

5 minutes ago

LMAO same! I picked out all the raisins when I was a kid, but these muffins balance them so well they don’t feel like weird little sweet bumps in your food. I’m obsessed.

This is the best review I’ve seen all week! So glad these won over a self-proclaimed raisin hater — that’s the ultimate seal of approval if you ask me.

5 minutes ago

Quick question! Can I use quick oats instead of old fashioned rolled oats for this? That’s all I have in my pantry right now and I really want to make these today instead of running to the store.

just now

Absolutely! Quick oats will work just fine here — the texture will be slightly less chewy, but the flavor will be identical. No need to adjust the baking time at all, enjoy!

Tried this recipe after my granddaughter sent it to me, and I have to say it’s a real classic. Not overly fussy, the ratios are spot on, the crumb is perfect. I’ve been baking oatmeal raisin muffins for 40+ years and this one is going in my permanent recipe box. Tastes just like the ones my mom used to make.

These are way lower in sugar than most muffin recipes I’ve tried, which is perfect for my post-gym breakfast. I added a scoop of vanilla protein powder to the batter and a handful of chopped walnuts for extra protein and crunch, and it worked so well. Definitely a new staple for my fitness routine.

yesterday

How much protein powder did you add? I’ve been trying to find a good high-protein muffin recipe that doesn’t come out dry as a brick!

2 hours ago

Just 1/3 cup! I used a plant-based vanilla one, and I added an extra splash of oat milk to keep the batter the right consistency, came out super moist with no chalky texture at all.

Served these at my weekend brunch alongside scrambled eggs, fresh fruit, and coffee, and all my friends asked for the recipe before they left. They pair so well with a little cream cheese spread on top, trust me on that. So much better than the sad store-bought muffins I almost bought instead.

yesterday

The cream cheese spread tip is insane! I tried it this morning when I made these and it felt like I was eating a fancy cafe muffin at home. Game changer.

yesterday

Wait, did anyone else’s muffins stick to the paper liners? I sprayed them with cooking spray but half the muffin stuck to the paper when I peeled it off. Flavor was amazing, I just lost half the muffin to the liner lmao. Any tips for next time?

yesterday

Let the muffins cool completely in the tin for 10 minutes before you take them out and peel the liners! I used to have this problem all the time until I started waiting, they pop right out now.

2 hours ago

Sorry to hear they stuck! The cooling tip above is spot on — if you let them rest in the tin for 10 minutes then transfer to a wire rack to cool fully, they won’t stick to the liners. You can also use parchment liners for extra insurance if you have them!

5 days ago

I skipped the raisins and added dried cranberries and orange zest for a little twist, and it was chef’s kiss. The base recipe is so versatile, you can swap in whatever dried fruit or mix-ins you have on hand and it still turns out perfect. Love easy, flexible recipes like this for busy weeks.

just now

These are the perfect coffee pairing! Not too sweet so they don’t clash with my dark roast, chewy, warm, just everything you want in a morning muffin. I warmed one up this morning and ate it while watching the sunrise on my porch, total little moment of joy before work.

just now

This sounds like the perfect morning! There’s nothing better than a warm muffin and a good cup of coffee to start the day off right. So glad you enjoyed them.

Made these yesterday and my golden retriever sat by the oven the entire time they baked begging for a bite. I gave him a tiny plain piece (no raisins, don’t worry — I know raisins are bad for pups!) and he did a little happy dance. 10/10, human and dog approved.
