Peanut Butter Chocolate Layer Cake

2. Make the Peanut Butter Frosting:
In a large bowl, beat the peanut butter and butter until creamy and smooth.
Gradually add powdered sugar, 1 cup at a time, mixing until combined.
Add heavy cream and vanilla extract. Beat until light, fluffy, and spreadable. Adjust the consistency with more cream if necessary.
3. Prepare the Chocolate Ganache:
Heat the heavy cream in a small saucepan until it begins to simmer. Remove from heat and pour over the chopped chocolate.
Let sit for 2 minutes, then stir until smooth. Stir in the butter for a glossy finish. Let the ganache cool slightly to thicken.
4. Assemble the Cake:
Place one chocolate cake layer on a serving plate. Spread a generous layer of peanut butter frosting on top.
Repeat with the second layer. Top with the final cake layer. Spread frosting over the top and sides of the cake.
Drizzle the cooled ganache over the cake, letting it drip down the sides for a dramatic effect.
5. Garnish and Serve:
Decorate with chopped mini peanut butter cups, crushed peanuts, and chocolate shavings. Chill for at least 1 hour before slicing to set the frosting and ganache.
