Timing

Instructions
Step 1: Bake the Cake
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- In a large bowl, combine the chocolate cake mix, cocoa powder, hot water, vegetable oil, eggs, and vanilla extract. Mix until well combined and smooth.
- Divide the batter evenly between the prepared cake pans.
- Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cakes cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
Step 2: Prepare the Butterfinger Filling
- In a medium bowl, combine the creamy peanut butter and powdered sugar. Mix until smooth.

Step 3: Assemble the Cake

- Place the second cake layer on top of the filling.
Step 4: Prepare the Ganache
- In a small saucepan, heat the heavy cream over medium heat until it begins to simmer.
- Remove from heat and add the chocolate chips and vanilla extract. Let sit for 2-3 minutes, then stir until smooth and glossy.
Step 5: Frost the Cake
- Pour the ganache over the top of the cake, allowing it to drip down the sides.
- Sprinkle additional crushed Butterfinger candies on top for decoration.
Step 6: Chill and Serve
