intro

Creamy vanilla fudge swirled with tangy blueberry compote and warm pie spice, capturing classic blueberry pie flavor in rich, bite-sized, easy-to-make pieces.

Ingredients

High-quality white chocolate, finely chopped 340 g (2 cups)
Sweetened condensed milk 397 g (1 ¼ cups, 1 standard 14oz can)
Fresh or frozen blueberries 150 g (1 cup)
Unsalted butter 57 g (4 tablespoons)
Graham cracker crumbs 30 g (¼ cup)
Fresh lemon juice 5 ml (1 teaspoon)
Pure vanilla extract 5 ml (1 teaspoon)
Ground cinnamon 2 g (1 teaspoon)
Fine sea salt 1 g (¼ teaspoon)

Steps

1

Prep baking pan

Line a 20cm (8x8 inch) square baking pan with parchment paper, leaving 5cm (2 inch) overhang on two opposite sides to easily lift set fudge out later. Lightly coat the exposed parchment with a thin layer of nonstick cooking spray, then set the prepared pan aside at room temperature.

step1:Prep baking pan
2

Cook blueberry compote

Place 150g (1 cup) blueberries, 5ml (1 tsp) fresh lemon juice, and 0.5g (¼ tsp) ground cinnamon in a small heavy-bottomed saucepan over medium-low heat. Cook for 6-8 minutes, stirring occasionally with a silicone spatula, until berries burst and the mixture reduces to a thick, jam-like consistency. Remove the pan from heat, transfer the compote to a small bowl, and let it cool to room temperature for 15 minutes before use.

3

Melt fudge base

Combine 340g (2 cups) finely chopped white chocolate, 397g (1 ¼ cups) sweetened condensed milk, 57g (4 tbsp) unsalted butter, 1.5g (¾ tsp) ground cinnamon, and 1g (¼ tsp) fine sea salt in a medium heatproof glass bowl. Set the bowl over a small saucepan of gently simmering water (double boiler setup, ensure the bottom of the bowl does not touch the water) over low heat. Stir constantly for 4-5 minutes, until all chocolate and butter are fully melted and the mixture is completely smooth with no visible lumps. Remove the bowl from heat, then stir in 5ml (1 tsp) pure vanilla extract until fully incorporated.

step3:Melt fudge base
4

Layer fudge components

Pour half of the warm fudge base into the prepared 8x8 pan, spreading it into a thin, even layer with a small offset spatula. Dollop half of the cooled blueberry compote across the fudge layer in 1-teaspoon sized blobs, then sprinkle 15g (2 tbsp) of the graham cracker crumbs evenly over the compote. Pour the remaining fudge base over the top, spreading gently to fully cover the first layer, then dollop the remaining blueberry compote across the surface in spaced blobs.

Step 4
step4:Layer fudge components
5

Swirl marbled pattern

Run a thin wooden skewer or paring knife through the fudge layers in a loose zig-zag pattern, dragging the tip across the pan both lengthwise and widthwise to create soft, marbled swirls of blueberry and vanilla fudge. Sprinkle the remaining 15g (2 tbsp) graham cracker crumbs evenly across the top of the fudge, pressing very gently with a clean finger to help the crumbs adhere to the surface.

Step 5
step5:Swirl marbled pattern
6

Chill fudge to set

Cover the pan loosely with plastic wrap, then transfer it to the refrigerator to chill for a full 2 hours, or until the fudge is completely firm to the touch and does not leave an indent when pressed lightly with a fingertip. Do not place the fudge in the freezer, as rapid freezing will cause the white chocolate to bloom and develop a dull, white powdery surface.

Step 6
step6:Chill fudge to set
7

Cut and serve fudge

Use the parchment paper overhang to lift the fully set fudge block out of the pan, transferring it to a wooden cutting board. Peel away the parchment paper, then use a sharp knife (warmed under hot running water and wiped completely dry between cuts) to slice the fudge into 2.5cm (1 inch) square pieces, yielding 64 total bite-sized pieces (16 servings of 4 pieces each). Serve chilled or at cool room temperature.

Tips

1.Avoid getting any water droplets in your melting fudge base, as even a tiny amount of water can cause white chocolate to seize into a grainy, lumpy mass that cannot be smoothed out.
2.Make sure your blueberry compote is fully cooled to room temperature before swirling it into the fudge; warm compote will melt the fudge base and turn the whole pan a muddy purple instead of creating a pretty, distinct marbled pattern.
3.Store cut fudge in an airtight container in the refrigerator for up to 1 week, or in the freezer for up to 3 months, separated by layers of parchment paper to prevent pieces from sticking together.

Blueberry Pie Fudge:Frequently Asked Questions

1.Can I use frozen blueberries instead of fresh for this blueberry pie fudge?
Absolutely! Frozen blueberries work just as well as fresh here—you don’t even need to thaw them first before making the compote swirl. Just add 1 to 2 extra minutes of cook time for the compote to boil off any excess released moisture, so extra water doesn’t make your fudge grainy or soggy as it sets.
2.Do I have to use high-quality white chocolate, or will cheap baking chips work?
I strongly recommend high-quality, finely chopped white chocolate for the creamiest final texture. Cheap white chips often have added waxes and stabilizers that prevent smooth melting, leading to clumpy, greasy fudge. If you only have chips, pick a premium brand with cocoa butter listed as the first fat for best results.
3.How do I keep the blueberry swirl from turning the whole batch of fudge purple?
Easy—don’t overmix! Once you spread the vanilla fudge base evenly in your lined pan, dollop spoonfuls of cooled blueberry compote across the top, then drag a toothpick or butter knife through in gentle S-curves to create swirls. Resist stirring the compote fully into the base for distinct, pretty ribbons.
4.Can I make this fudge without graham cracker crumbs?
You can skip the graham cracker crumbs if you don’t have them on hand, but they add that iconic, toasty pie-crust note that makes this fudge taste like actual blueberry pie. If you’re out, swap in crushed vanilla wafer crumbs or finely crushed shortbread cookies for a similar warm, crumbly texture contrast.
5.How long does this fudge need to set before I can cut it into pieces?
For clean, sharp cuts, let the fudge chill fully in the refrigerator for at least 4 hours, or ideally overnight. Don’t try to rush the process by sticking it in the freezer, as that can cause the chocolate to seize or develop a chalky, uneven texture once it thaws back to serving temperature.
6.Why did my fudge turn out grainy instead of smooth and creamy?
Grainy fudge almost always stems from one of two common missteps: either you overheated the white chocolate when melting it with condensed milk, or your blueberry compote was too hot when you swirled it in. Melt ingredients over low heat, and let compote cool fully before adding it to the fudge base.
7.Can I add extra pie spice for a warmer, more spiced flavor?
Absolutely! The base recipe uses a subtle amount of pie spice to complement, not overpower, the bright blueberry and sweet white chocolate flavors. Start with an extra 1/4 teaspoon of cinnamon-forward pie spice at a time, tasting the fudge base as you go, so you don’t end up with fudge that tastes like spiced candy instead of blueberry pie.
8.What’s the best way to store leftover blueberry pie fudge?
Store cut fudge pieces in an airtight container, separated by sheets of parchment paper to prevent sticking, in the refrigerator for up to 2 weeks. You can also keep it at cool room temperature (under 70°F) for 3 to 4 days, but the chilled texture is extra rich and creamy, just like a cold slice of blueberry pie.
9.Can I freeze this fudge to enjoy later?
Yes! This fudge freezes beautifully for up to 3 months. Wrap individual pieces tightly in plastic wrap, then tuck them into a labeled freezer bag to prevent freezer burn. When you’re ready to eat, let a piece thaw in the fridge for 2 to 3 hours—don’t thaw at room temp, or condensation can make the surface sticky.
10.Do I need a candy thermometer to make this fudge?
Nope! Unlike old-fashioned cooked fudge that requires precise temperature checks to hit soft-ball stage, this easy, no-fuss recipe uses sweetened condensed milk to create a stable, creamy base without boiling sugar. All you need is a saucepan, a lined pan, and a stirring spoon—no special equipment required.
11.Can I use salted butter instead of unsalted for this recipe?
You can, just skip any extra pinch of salt the recipe calls for. Salted butter has variable salt content across brands, so using unsalted lets you control the exact salt level to balance the sweet white chocolate and tangy blueberries. If you use salted, the fudge will still taste great, just a touch saltier.
12.How do I prevent the fudge from sticking to the pan when I take it out?
Always line your baking pan with two crisscrossed sheets of parchment paper, leaving 2-inch overhangs on all sides to act as handles. Don’t rely on cooking spray alone, as the sticky fudge can still bond to unlined pan edges. When fully set, just lift the whole slab out by the overhangs for mess-free cutting.
13.My blueberry compote is really runny—will that ruin the fudge?
It won’t ruin the batch entirely, but overly runny compote can create soggy, wet pockets in the set fudge. If your compote is thin, simmer it for 3 to 5 extra minutes over medium-low heat until it thickens to a jam-like consistency, then let it cool fully before swirling. It will thicken more as it cools, so don’t overcook it to a gummy texture.
14.Can I adapt this recipe to be dairy-free for friends with allergies?
You can adapt it easily! Swap the regular white chocolate for a high-quality dairy-free white chocolate made with cocoa butter, use full-fat canned coconut sweetened condensed milk, swap the butter for vegan stick butter, and confirm your graham cracker crumbs are dairy-free. The texture and flavor will be nearly identical to the original.
15.What size pan should I use for the thickest, best fudge pieces?
An 8x8-inch square baking pan is perfect for this recipe, giving you thick, bite-sized 1-inch fudge pieces that hold their shape well. If you only have a 9x13-inch pan, your fudge will be much thinner, so reduce chill time by about an hour and cut smaller pieces to avoid them breaking apart.
16.Can I mix the graham cracker crumbs right into the fudge base?
You absolutely can, but I prefer sprinkling half the crumbs on the bottom of the lined pan before adding the fudge, and the other half on top with the compote swirl. That creates a crumbly “pie crust” layer on the top and bottom, instead of evenly distributed crumbs, for a more authentic blueberry pie experience.
17.How do I get clean, smooth cuts when slicing the set fudge?
Grab a sharp, thin-bladed knife, and run it under hot water for 10 seconds, then wipe it dry with a paper towel between every single cut. The warm knife glides through the chilled fudge without sticking or pulling at the blueberry swirls, giving you neat, professional-looking edges on every bite-sized piece.
18.Can I add extra mix-ins like nuts or extra chocolate chips to this fudge?
Go for it! Toasted, chopped pecans or walnuts pair beautifully with blueberry and warm pie spice, or you can toss in extra white chocolate chips for even more richness. Just keep total mix-ins to 1/2 cup, so you don’t overload the fudge base and make it crumbly instead of smooth and creamy.
19.Can I use store-bought blueberry jam instead of making homemade compote for the swirl?
Definitely! If you don’t want to make the quick blueberry compote from scratch, a thick, high-quality blueberry jam (preferably one with a bright, tangy profile, not overly sweet) works as a perfect swap. Just avoid thin, syrupy jam, as it will create soggy, wet pockets in your set fudge just like runny homemade compote.

OMG I brought this to our neighborhood block party potluck last weekend and people were hounding me for the recipe all night! The blueberry pie flavor cuts through the rich white chocolate fudge so perfectly, it’s not too cloying at all. Game changer for my summer dessert spread!

Wait did you use fresh or frozen blueberries for this? I’m making it for my book club next week and don’t wanna mess it up!

Great question! Fresh blueberries work best here, but if you use frozen, make sure to thaw and drain them really well first so extra juice doesn’t make the fudge runny. So glad it was a potluck hit!

SO good. I’ve made fudge a dozen times and this is easily top 3. The little pie crumble bits on top? *Chef’s kiss* My roommate ate half the pan before it even fully set, no joke.

My kids loved it! I was worried the blueberry flavor would be too tart for my picky 7 year old but he asked for seconds before he even finished his first piece. Super easy to follow too, which is a win for chaotic weeknights when I don’t have time for fancy baking.

Really tasty! I swapped the regular pie crust crumble for a gluten free shortbread crumble to fit my dietary needs and it turned out amazing. Only reason I’m not giving 5 stars is I had to chill mine an extra 45 minutes longer than the recipe said to get it to set fully, maybe my kitchen was just too warm?

Oh thank you for saying that! I was stressing because mine was still soft after the 2 hour chill mark, thought I messed up the ratios!

Love the gluten free shortbread swap idea! Kitchen temperature can totally impact set time — if your space is extra warm, popping it in the fridge for a little extra time is absolutely the right call, no mistake made!

Made this for our post-hike snack stop last weekend and it held up way better than I thought it would in the cooler! The blueberry taste is so bright, it felt like a fancy little reward after 6 miles on the trail. Will definitely make again for our next trip.

I’ve been making fudge for my grandkids every summer for 40 years, and this recipe is such a fun twist on the classic. Tastes just like the blueberry pie I used to bake with my mom when I was a kid, it brought back so many sweet memories.

This is exactly why I want to make it! I miss my grandma’s blueberry pie so bad, can’t wait to try this fudge version to get that cozy vibe without rolling out a whole finicky pie crust.

Made a batch for the office break room and it was gone in 20 minutes flat. People were asking if I bought it from a fancy candy shop, little do they know how dead simple this recipe is! Even our intern who hates fruity desserts went back for a second piece.

Just pulled this out of the fridge to cut and snuck a bite while my daughter wasn’t looking — holy cow this is good. I added a tiny extra drizzle of white chocolate on top for fun, can’t wait to see her face when she gets home from soccer practice.

The white chocolate drizzle idea is genius! I’m making these for my daughter’s end of season soccer team party, that’s gonna make them look so cute and festive.

10 minutes ago

Love the extra white chocolate drizzle touch! If you want to make them extra fun for the team, you could even add little blue sugar sprinkles on top of the drizzle before it sets for a pop of color.

Super easy to make in my tiny dorm kitchen with just my microwave and mini fridge, no fancy equipment needed which is a huge win. Only note is I wish there was a little more blueberry punch, next time I might swirl in a bit extra blueberry jam into the fudge base before chilling. Still solid though, my whole floor is obsessed.

I cut these into little bite sized pieces and stored them in the freezer for quick sweet treats all week, they freeze SO well! Perfect for when that 3pm sugar craving hits at work, way better than hitting the vending machine.

Wait how long do they keep in the freezer for? I wanna make a big batch ahead of my sister’s high school graduation party next month!

First time ever making fudge and I didn’t mess it up!!! I was so nervous I’d burn the white chocolate or it wouldn’t set, but the step by step instructions were so clear even a total beginner like me could pull it off. It looks like it came straight out of a fancy bakery!

Took this to my family’s 4th of July cookout and paired it with fresh strawberry skewers and vanilla ice cream for a little red white and blue dessert spread. Everyone raved about how the tart blueberry balanced out the super sweet fudge, chef’s kiss.

That 4th of July spread sounds absolutely perfect! What a fun, festive way to serve this fudge — we’re definitely stealing that idea for our next holiday get together.

Used wild blueberries I picked up at my local upstate farmers market for this and the flavor was out of this world. It’s creamy, fruity, has that perfect little crumble crunch on top — I’m already planning to make a double batch for my best friend’s birthday next week.
