Ingredients
For the Chocolate Cake:
- 1 box chocolate cake mix (or homemade chocolate cake recipe)
- 3 large eggs
- 1 cup water
- ½ cup vegetable oil
- 1 teaspoon vanilla extract
For the Peanut Butter Filling:
- 1 cup creamy peanut butter
- 8 oz cream cheese, softened
- 1 cup powdered sugar
- 1 teaspoon vanilla extract
- 1 cup whipped topping (like Cool Whip)
For the Butterfinger Topping:
- 3-4 Butterfinger candy bars, crushed
- ½ cup chocolate chips (semi-sweet or milk chocolate)
- 2 tablespoons heavy cream
For the Frosting:
- 1 can chocolate frosting (or homemade frosting)
- 1-2 Butterfinger candy bars, crushed (for garnish)
Step-by-Step Recipe
1. Prepare the Chocolate Cake:
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line them with parchment paper.
- In a large bowl, combine the chocolate cake mix, eggs, water, vegetable oil, and vanilla extract. Mix according to the package instructions or until the batter is smooth.
- Pour the batter evenly into the prepared cake pans.
- Bake for 25-30 minutes or until a toothpick inserted into the center of the cakes comes out clean. Allow the cakes to cool in the pans for about 10 minutes, then transfer them to a wire rack to cool completely.
2. Make the Peanut Butter Filling:
- In a large bowl, beat the creamy peanut butter and softened cream cheese together until smooth and creamy.
- Add the powdered sugar and vanilla extract, and continue mixing until well combined.
- Gently fold in the whipped topping until the mixture is light and fluffy.
3. Make the Butterfinger Topping:
- Crush the Butterfinger candy bars into small pieces, either by hand or with a rolling pin. Set aside.
- In a small saucepan, melt the chocolate chips and heavy cream together over low heat, stirring constantly until smooth.
- Once melted, remove from heat and set aside to cool slightly.
4. Assemble the Cake:
- Once the cakes are completely cooled, place one layer on a cake platter or serving dish.
- Spread a generous layer of the peanut butter filling over the first cake layer.
- Place the second cake layer on top of the peanut butter layer.
- Frost the entire cake with the chocolate frosting, covering the sides and top evenly.
5. Add the Butterfinger Topping:
- Drizzle the melted chocolate over the top of the frosted cake.
- Sprinkle the crushed Butterfinger candy bars evenly over the top, ensuring the entire cake is covered in the crunchy goodness.
- If desired, garnish with additional Butterfinger pieces around the edges or on the sides.
6. Chill and Serve:
- Refrigerate the cake for at least 1 hour before serving to allow the layers to set and the flavors to meld.
- Slice and enjoy the amazing combination of chocolate, peanut butter, and Butterfinger crunch in every bite!
Tips for the Perfect Butterfinger Bomb Cake
- For an extra creamy filling: Use room temperature cream cheese to avoid lumps in the peanut butter filling.
- Cake texture: If you want a richer, denser cake, try using buttermilk instead of water in the cake mix.
- Storage: Store leftover cake in the fridge for up to 3-4 days. It keeps well and actually gets even better after a day or two!
- Customization: If you’re a fan of extra peanut butter flavor, you can add a little extra peanut butter to the frosting or filling.
Variations
- Mini Butterfinger Bomb Cakes: Make individual mini cakes or cupcakes by using muffin tins instead of cake pans.
- Drizzle with caramel: For an added layer of sweetness, drizzle some caramel sauce over the top along with the chocolate and Butterfinger topping.
- Peanut Butter Chocolate Ganache: For a fancier look, substitute the melted chocolate and cream with a peanut butter chocolate ganache for an even richer flavor.
Health Considerations and Nutritional Value
This cake is definitely on the indulgent side, packed with sugar, butter, and candy. For a slightly lighter version, you can swap the frosting for a whipped chocolate mousse or reduce the amount of candy topping. However, for a treat like this, it’s best enjoyed in moderation!
