Description
A rich and indulgent chocolate cake layered with creamy peanut butter filling and topped with a glossy dark chocolate ganache, perfect for any dessert lover.
Ingredients
Scale
- 1 box chocolate cake mix (standard size, approx. 15–18 oz)
- 1 cup water
- 1/2 cup vegetable oil
- 3 large eggs
- 1 cup creamy peanut butter (smooth)
- 1 cup powdered sugar (confectioners’ sugar)
- 1 cup heavy cream (for ganache)
- 8 oz dark chocolate (chopped; 60–70% cacao recommended)
Instructions
- Preheat the oven according to the cake mix instructions and grease and flour a 9×13-inch pan or two 8-inch round pans.
- In a large bowl, combine the chocolate cake mix, 1 cup water, 1/2 cup vegetable oil, and 3 large eggs. Beat until smooth and uniform.
- Pour the batter into the prepared pan(s) and bake according to the package instructions, typically 25–35 minutes for a 9×13 or 22–28 minutes for 8-inch rounds.
- While the cake bakes, mix together 1 cup creamy peanut butter and 1 cup powdered sugar until smooth.
- Let the baked cake cool completely. If using two round layers, slice each in half horizontally.
- Spread the peanut butter filling between the layers or on top of the cooled single-layer cake.
- For the ganache, heat 1 cup heavy cream until just simmering and pour over 8 oz chopped dark chocolate. Let sit and stir until smooth.
- Pour the ganache over the assembled cake, letting it drip down the sides.
- Allow the ganache to set at room temperature for 30–45 minutes before slicing and serving.
Notes
For a deeper peanut flavor, fold in 1/2 cup chopped roasted peanuts. Adjust the sweetness of the peanut butter filling to taste.
