A luscious German-American fusion twist on classic Black Forest flavors, pairing juicy blueberries, rich dark chocolate, and fluffy cream in a buttery chocolate crumb crust.

Ingredients

Fresh blueberries 4 cups (600g), divided
70% cacao dark chocolate 4 oz (113g), chopped, divided
Heavy whipping cream 1 cup (240ml), chilled
Chocolate graham cracker crumbs 1 ½ cups (180g)
Unsalted butter 6 tbsp (85g), melted
Granulated sugar ½ cup plus 2 tbsp (125g), divided
Cornstarch 3 tbsp (24g)
Lemon juice 2 tbsp (30ml)
Cold water ¼ cup (60ml)
Vanilla extract 1 tsp (5ml)
Almond extract ¼ tsp (1.25ml)
Powdered sugar 2 tbsp (15g)
Fresh sweet cherries ¼ cup (30g), pitted

Steps

1

Bake the chocolate crust

Preheat oven to 175°C (350°F). In a medium bowl, mix 1 ½ cups chocolate graham cracker crumbs, 2 tbsp granulated sugar, and 6 tbsp melted unsalted butter until crumbs are evenly moistened. Press the mixture firmly into the bottom and up the sides of a 9-inch pie dish. Bake for 10 minutes, then transfer to a wire rack to cool completely for 20 minutes before filling.

step1:Bake the chocolate crust
2

Cook the blueberry filling

In a medium saucepan over medium heat, combine 3 cups of fresh blueberries, ½ cup granulated sugar, 3 tbsp cornstarch, ¼ cup cold water, and 2 tbsp lemon juice. Stir constantly as the mixture comes to a gentle simmer, cooking for 6-8 minutes until blueberries burst and the sauce thickens to a jam-like consistency that coats the back of a spoon. Remove from heat, stir in 1 tsp vanilla extract, ¼ tsp almond extract, and 2 oz (57g) of the chopped dark chocolate, stirring until chocolate fully melts.

step2:Cook the blueberry filling
3

Fill and chill the pie

Fold the remaining 1 cup of whole fresh blueberries into the warm filling, then pour the entire mixture into the fully cooled chocolate crust. Spread the filling evenly with a spatula, then cover the pie loosely with plastic wrap and refrigerate for a minimum of 2 hours until the filling is fully firm and set.

Step 3
step3:Fill and chill the pie
4

Make chocolate shavings

While the pie chills, melt the remaining 2 oz (57g) of chopped dark chocolate in a heatproof bowl set over a pan of barely simmering water (double boiler method), stirring for 2-3 minutes until completely smooth. Pour the melted chocolate in a thin layer onto a parchment-lined baking sheet, spread to ⅛-inch thickness, and chill for 10 minutes until firm. Use a metal spatula to scrape the chocolate into delicate curls and shavings, set aside for garnish.

5

Whip the cream topping

In a cold medium bowl, combine 1 cup cold heavy whipping cream and 2 tbsp powdered sugar. Whip with an electric mixer on medium speed for 2-3 minutes until soft, billowy peaks form that hold their shape without drooping. Take care not to overwhip, as this will cause the cream to curdle.

Step 5
step5:Whip the cream topping
6

Garnish and serve the pie

Once the pie filling is fully set, remove the plastic wrap. Dollop the whipped cream evenly over the top of the pie, or pipe it in decorative rosettes if preferred. Sprinkle the reserved dark chocolate shavings over the cream, and top with ¼ cup pitted fresh sweet cherries for a classic Black Forest touch. Slice into 8 even wedges and serve chilled.

Tips

1.For clean, neat slices, chill the fully assembled pie for 30 extra minutes after adding toppings, and dip your sharp knife in hot water, wiping it dry between each cut.
2.If fresh blueberries are unavailable, use frozen unsweetened blueberries; add 1 extra tablespoon (8g) of cornstarch to the filling to compensate for extra released juice during cooking.
3.For a traditional adult Black Forest twist, stir 1 tbsp (15ml) of kirsch (cherry brandy) into the warm filling; omit almond extract if serving guests with nut allergies.

Blueberry Black Forest Pie:Frequently Asked Questions

1.Can I use frozen blueberries instead of fresh for this pie, and do I need to adjust the prep?
Absolutely! Thaw frozen blueberries fully first, then drain off all excess released juice to avoid a soggy crust. Toss the drained berries with 1 extra teaspoon of cornstarch before layering to help the filling set properly, and pat fresh in-season berries dry after rinsing to keep their structure firm.
2.I don’t love super dark chocolate—can I swap the 70% cacao dark chocolate for a lower cacao option?
You can, but stick to no lower than 55% cacao to keep that rich, balanced Black Forest depth without making the pie overly sweet. Milk chocolate will make the layers cloyingly sweet paired with the graham crust and sweet blueberries, so save that for a small garnish if you prefer a milder chocolate flavor.
3.My chocolate graham cracker crust always falls apart when I slice the pie—how do I get it to hold its shape?
Two quick, foolproof fixes here: First, mix the crumbs with fully melted, not just softened, unsalted butter so every crumb is evenly coated. Second, press the crust firmly into the pan and chill it for at least 30 minutes before adding any fillings to let the butter set and bind the crumbs solidly.
4.How do I keep the heavy whipping cream layer from getting runny a few hours after assembling the pie?
Whip cold heavy cream to stiff, not soft, peaks—stop when the cream holds a sharp, upright point when you lift your mixer attachment. For extra stability, especially if serving at a warm gathering, fold in 1 tablespoon of sifted powdered sugar and ¼ teaspoon of dissolved unflavored gelatin before spreading it over the filling.
5.Can I make this Blueberry Black Forest Pie ahead of time, and how should I store leftovers?
You can prep the crust and cooked blueberry filling 2 days ahead, stored separately in the fridge, but wait to whip the cream and assemble the pie no more than 4 hours before serving. Once assembled, keep it loosely covered in the fridge, and avoid freezing it, as the cream and blueberries will turn mushy when thawed.
6.I always burn or seize dark chocolate when melting it for desserts—what’s the foolproof method for this recipe?
Chop the 70% dark chocolate into uniform, pea-sized pieces so it melts evenly, then heat it in 30-second bursts in the microwave, stirring fully between each burst. Stop heating when 70% of the chocolate is melted, then stir continuously until the remaining lumps dissolve to avoid grainy, seized chocolate.
7.What easy, crowd-pleasing garnishes pair well with this pie without overpowering its core flavors?
Stick to simple, complementary toppings: a light dusting of unsweetened cocoa powder, a handful of fresh whole blueberries, a few thin shavings of extra dark chocolate, or a tiny dollop of extra whipped cream per slice. Skip heavy syrups or candy toppings, as they’ll throw off the bright berry and rich chocolate balance.
8.Can I adapt this pie to be gluten-free for friends with dietary restrictions?
Easily! Swap the regular chocolate graham cracker crumbs for certified gluten-free chocolate graham crumbs, or make your own crumbs from gluten-free chocolate sandwich cookies (scrape out the creamy filling first). Double check that your dark chocolate is labeled gluten-free, as some budget brands add wheat-based thickeners.
9.What’s the trick to getting clean, neat slices when I serve this pie instead of oozing, messy cuts?
Chill the fully assembled pie for at least 2 hours before slicing to let all the layers set firmly. When ready to cut, dip a sharp, thin-bladed knife in hot water, wipe it dry with a paper towel, and make one smooth cut—repeat the hot water wipe between every slice for restaurant-worthy pieces.

OMG this Blueberry Black Forest Pie was the star of our Sunday family dinner! I was a little nervous tackling a medium difficulty recipe, but the steps were so clear. The tart blueberries cut through the rich chocolate perfectly, SO good. My kids asked for second slices before they even finished their first!

yesterday

This makes our day so happy to hear! We love that the blueberry brightness balances the deep chocolate and cherry notes too—so glad your whole family enjoyed it. Pro tip next time: a dollop of freshly whipped cream on top takes it over the top!

Brought this to my office potluck yesterday and people were literally scraping the pie plate clean. I was worried the 1 hour 5 minute cook time would cut into my morning commute prep, but I pre-baked the crust the night before and it came together seamlessly. Absolute game changer, will be making this for every summer gathering from now on.

The flavor combo is insane, I’ll give it that! I ran into a little trouble with my crust getting too dark around the edges halfway through baking, though—ended up having to wrap it in foil mid-cook, which stressed me out a little. Still tasted amazing, my roommate ate half the pie in one sitting lol.

2 days ago

Oh I had the same issue my first time making it! I just keep a strip of foil ready to go around the crust edges right when I pop it in the oven now, no more burnt edges at all. Works like a charm!

2 days ago

Great tip from Beth! We always recommend shielding crust edges with foil after the first 20 minutes of baking to prevent over-browning, especially if your oven runs a little hot. So glad the flavor still won you over despite the hiccup!

Made this for my post-hike picnic with friends last weekend and it held up so much better than I expected! I used wild blueberries I picked on a trail the week before (froze them first) and it added such a nice, bright pop. 10/10, even my friend who swears he ‘doesn’t like fruit pie’ went back for thirds.

5 days ago

Wait using frozen wild blueberries is such a smart call! I’ve been using fresh store-bought and they’re so pricey right now, I’m definitely grabbing a bag of frozen for my next bake. Did you thaw them first or toss them in frozen?

5 days ago

I was skeptical this pie would hold up for meal prep but I sliced it up and kept individual slices in airtight containers in the fridge for 4 days and they tasted just as good as day one! The chocolate layer doesn’t get soggy at all, which is a total win for my weekday sweet treats. No more sad vending machine chocolate bars for me!

I’m pretty new to baking so this medium difficulty pie was a bit of a stretch for me. My filling came out a little runnier than I expected when I pulled it out, I think I didn’t let it cool long enough before slicing? It still tasted good but was pretty messy to serve at my partner’s birthday dinner.

1 week ago

So sorry the filling was runny for you! That almost always comes down to not letting the pie cool for the full recommended 2 hours after baking (we know, it’s so hard to wait!) so the filling has time to set. Give it another try sometime and let it rest fully, we promise it slices cleanly!

Y’all, I swapped the regular dark chocolate for dark chocolate with sea salt and I am NEVER going back. The little salty kick with the sweet blueberries and cherry layers is absolute heaven. My neighbor came over to borrow a cup of sugar and ended up staying for two slices, haha.

5 minutes ago

OH that sea salt chocolate swap is genius! I always add a flaky sea salt sprinkle on top of my chocolate desserts but never thought to use salted chocolate in the filling. I’m making this for my book club next week and I’m 100% stealing that hack.

just now

Wait we have the same book club? No but seriously, if you bring that salted chocolate version I will fight someone for the last slice. I’ve been looking for a new pie recipe to make for our next meeting and this just jumped to the top of the list.
