Step-by-Step Instructions
This cake is made in several stages, each adding to its rich flavor and stunning appearance.
1. Prepare the Cake Batter
Preheat your oven to 350°F (175°C) and grease and line two 9-inch round cake pans with parchment paper.
In a large bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt.
In another bowl, whisk the sugar, buttermilk, oil, eggs, and vanilla until smooth. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Stir in the boiling water, which will thin the batter—this ensures a moist and fluffy cake.
2. Bake the Cake Layers
Divide the batter evenly between the prepared pans. Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.
Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.
3. Make the Peanut Butter Frosting
In a large bowl, beat the peanut butter and butter until smooth and creamy. Gradually add the powdered sugar, mixing well after each addition.
Stir in the heavy cream and vanilla extract, beating until the frosting reaches a spreadable consistency. Set aside.
4. Prepare the Chocolate Ganache
Heat the heavy cream in a small saucepan over medium heat until it just begins to simmer.
Pour the hot cream over the chocolate chips in a bowl. Let it sit for a minute, then stir until smooth and glossy. Allow the ganache to cool slightly before using.
5. Assemble the Cake
Place one cake layer on a serving plate. Spread a generous layer of peanut butter frosting on top.
Add the second cake layer and frost the entire cake with the remaining frosting. Drizzle the ganache over the cake, letting it drip down the sides for a dramatic effect.
Garnish with chopped peanuts, mini peanut butter cups, or chocolate shavings for an extra touch of decadence.
Tips for the Best Chocolate Peanut Butter Cake
- Use Room Temperature Ingredients: Room temperature butter and eggs blend more evenly into the batter and frosting.
- Don’t Overmix: Overmixing the batter can lead to a dense cake, so mix until just combined.
- Chill the Cake Before Frosting: This prevents crumbs from mixing into the frosting and makes assembly easier.
- Use Quality Ingredients: High-quality cocoa powder, chocolate, and peanut butter make a noticeable difference in flavor.
Variations to Try
- Triple Layer Cake: Add an extra layer for an even more impressive dessert.
- Cupcake Version: Use the same batter and frosting to make cupcakes, adjusting the baking time to 18–20 minutes.
- Peanut Butter Filling: Add a layer of peanut butter cups or peanut butter mousse between the cake layers.
- Gluten-Free Option: Substitute the all-purpose flour with a 1:1 gluten-free baking flour.
Serving Suggestions
- Serve this cake with a scoop of vanilla ice cream or a dollop of whipped cream.
- Pair it with a glass of cold milk, a cup of hot coffee, or a peanut butter latte for the perfect match.
Storing the Cake
- Refrigeration: Store the cake in an airtight container in the fridge for up to 5 days. Allow it to come to room temperature before serving.
- Freezing: Wrap individual slices in plastic wrap, then foil, and freeze for up to 3 months. Thaw in the refrigerator overnight.
