Instructions
Preparation
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- In a large mixing bowl, sift together the all-purpose flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt.
- In another bowl, combine warm water, sour cream, vegetable oil, eggs, and vanilla extract. Whisk until smooth.
Baking and Assembling
- Gradually add the wet mixture to the dry ingredients and mix until just combined.
- Divide the batter evenly between the prepared cake pans. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
- Cool the cakes in the pans for 10 minutes, then transfer them to wire racks to cool completely.
- For the frosting, beat softened butter and peanut butter together until creamy. Gradually add powdered sugar and then heavy whipping cream until light and fluffy.
- Once cooled, place one cake layer on a serving platter, spread frosting on top, and then add the second layer. Frost the top and sides of the cake.
Ganache and Decoration
- To make the ganache, heat heavy whipping cream until simmering. Add chocolate chips and stir until fully melted.
- Pour ganache over the top of the cake, letting it drip down the sides. Decorate with chopped Reese's Peanut Butter Cups and drizzle additional peanut butter if desired.
Serving
- Slice and serve your delicious cake, enjoying the chocolate and peanut butter flavors in every bite.
