Step-by-Step Instructions
1. Prepare the Oven and Pan
Preheat your oven to 350°F (175°C).
Grease a 9 × 13-inch baking pan and line the bottom with parchment paper.
2. Mix the Dry Ingredients
In a large bowl, whisk together:
- Flour
- Cocoa powder
- Sugar
- Baking powder
- Baking soda
- Salt
Whisk until evenly combined.
3. Add the Wet Ingredients
Add the eggs, buttermilk, vegetable oil, and vanilla extract.
Mix until the batter is smooth.
Slowly pour in the hot coffee or hot water while mixing gently.
The batter will be relatively thin. This is normal and helps produce a moist chocolate cake.
4. Bake the Chocolate Cake
Pour the batter into the prepared pan.
Bake at 350°F (175°C) for 25–30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Do not overbake.
Allow the cake to cool completely in the pan.
Prepare the Peanut Butter Filling
5. Beat the Cream Cheese and Peanut Butter
In a large mixing bowl, beat the softened cream cheese and peanut butter until smooth and creamy.
Add powdered sugar and vanilla extract.
Beat again until completely combined.
6. Whip the Cream
In a separate bowl, whip the cold heavy cream until medium-stiff peaks form.
Gently fold the whipped cream into the peanut butter mixture.
This creates a light, creamy filling without making it overly dense.
7. Add the Blueberries
Gently fold the fresh blueberries into the peanut butter cream.
Avoid vigorous mixing because the berries can release too much juice and discolor the filling.
Assemble the Cake
8. Create the Layers
Once the chocolate cake has cooled completely, carefully spread the peanut butter filling evenly over the top.
Smooth the surface with a spatula.
Refrigerate for approximately 30–45 minutes while preparing the chocolate topping.
Prepare the Chocolate Topping
9. Make the Chocolate Ganache
Place the chopped chocolate in a heatproof bowl.
Heat the heavy cream in a small saucepan over medium heat until it is hot and just beginning to steam. Do not boil it vigorously.
Pour the hot cream over the chocolate.
Let it stand for approximately 2 minutes.
Whisk gently until smooth and glossy.
Add the butter and stir until melted.
10. Finish the Cake
Pour the chocolate ganache over the chilled peanut butter layer.
Use an offset spatula to spread it evenly across the surface.
Refrigerate the cake for at least 2 hours, or until the filling is firm and the chocolate topping has set.
11. Slice and Serve
For clean slices, use a sharp knife warmed under hot water and wiped dry before each cut.
Garnish with a few fresh blueberries, chopped peanuts, or small mint leaves if desired.
Best Tips
🍫 Use Quality Cocoa Powder
Good-quality unsweetened cocoa powder gives the chocolate cake a deeper flavor.
🥜 Choose Creamy Peanut Butter
Traditional creamy peanut butter produces the smoothest filling. Avoid very runny natural peanut butter unless it has been thoroughly stirred.
🫐 Keep the Blueberries Dry
Wash the blueberries and dry them completely before adding them to the filling.
❄️ Chill Between Layers
Chilling helps the peanut butter filling become firm enough to support the chocolate topping.
🔪 Use a Warm Knife
For professional-looking slices, warm your knife in hot water, dry it, and slice. Clean and repeat between cuts.
Don’t Overbake the Cake
The chocolate cake should remain moist. A few moist crumbs on the toothpick are preferable to a completely dry toothpick.
Best Ingredient Options
Chocolate: Semi-sweet chocolate creates a balanced topping, while dark chocolate provides a more intense flavor.
Peanut Butter: Creamy conventional peanut butter gives the most stable filling.
Blueberries: Fresh blueberries are ideal, but frozen blueberries can be used if thawed and thoroughly drained.
Cream Cheese: Full-fat cream cheese gives the filling the best structure and richness.
Buttermilk: If you don’t have buttermilk, combine 1 cup milk with 1 tablespoon lemon juice or vinegar and let it stand for 5 minutes.
Recipe Variations
🍓 Chocolate Peanut Butter Strawberry Cake
Replace the blueberries with chopped fresh strawberries.
🍌 Chocolate Peanut Butter Banana Cake
Add thinly sliced bananas between the chocolate cake and peanut butter filling.
🥜 Extra Peanut Butter
Drizzle melted peanut butter over the chocolate topping before it sets.
🍫 Dark Chocolate Version
Use 70% dark chocolate for the ganache to create a richer, less sweet topping.
🫐 Mixed Berry Version
Use a combination of blueberries, raspberries, and blackberries.
🍪 Cookie Crunch
Add a layer of crushed chocolate sandwich cookies between the cake and peanut butter filling.
What to Serve With
This rich dessert pairs especially well with:
- ☕ Freshly brewed coffee
- 🥛 Cold milk
- 🫖 Black tea
- 🍓 Fresh berries
- 🍨 Vanilla ice cream
- 🥄 Whipped cream
- 🍫 Hot chocolate
A scoop of vanilla ice cream is especially delicious alongside the chilled chocolate cake.
Make-Ahead Instructions
This cake is an excellent make-ahead dessert.
You can assemble the entire cake 1 day before serving. Keep it covered and refrigerated.
For the best presentation, add fresh blueberries or other decorative toppings shortly before serving.
Storage
Store leftover cake covered in the refrigerator.
It will keep well for approximately 3–4 days.
Because the filling contains cream cheese and whipped cream, keep the cake refrigerated and avoid leaving it at room temperature for extended periods.
Reheating
This dessert is best served chilled.
Do not reheat the entire cake.
If desired, allow individual slices to sit at room temperature for approximately 10–15 minutes before serving for a softer, creamier texture.
Freezing
This cake can be frozen, although the blueberries and creamy filling may change slightly in texture after thawing.
For best results:
- Chill the cake completely.
- Cut it into individual portions.
- Wrap each piece tightly.
- Place the wrapped slices in a freezer-safe container.
- Freeze for up to 1 month.
- Thaw overnight in the refrigerator.
Common Mistakes to Avoid
❌ Adding Hot Ganache to Soft Filling
Let the ganache cool slightly before pouring it over the peanut butter layer.
❌ Using Wet Blueberries
Excess moisture can loosen the filling.
❌ Overmixing the Whipped Cream
Stop once medium-stiff peaks form.
❌ Cutting Before Chilling
The filling needs time to firm up, otherwise the layers may slide apart.
❌ Overbaking the Chocolate Cake
A dry cake can overpower the creamy filling.
❌ Using Too Much Ganache
A thick topping can make the cake difficult to slice cleanly. Spread it into an even layer.

Frequently Asked Questions
Can I use frozen blueberries?
Yes. Thaw them completely and drain them very well before adding them to the filling.
Can I make this cake without cream cheese?
Yes. You can make a simpler peanut butter mousse using peanut butter, powdered sugar, and whipped cream, although cream cheese gives the filling more stability.
Can I use milk chocolate for the topping?
Yes. Milk chocolate creates a sweeter and creamier topping. If using milk chocolate, you may want to slightly reduce the amount of cream.
Why is my peanut butter filling too soft?
The cream may have been under-whipped, or the ingredients may have been too warm. Refrigerating the assembled cake usually helps firm the filling.
Can I use a different pan?
Yes, but the baking time will change. A square 9 × 9-inch pan will create a thicker cake and may require additional baking time.
How do I get clean cake slices?
Chill the cake thoroughly and use a warm, sharp knife. Wipe the knife clean between slices.
Can I make this dessert ahead of time?
Yes. Preparing it the day before is actually ideal because the layers have time to set and the flavors have time to develop.
