7. While the cakes are baking, prepare the peanut butter truffle. In a bowl, mix the peanut butter, icing sugar, melted butter, and milk until smooth.

8. Once the cakes are ready, let them cool in the pans for about 10 minutes before turning them out onto a wire rack to cool completely.

9. When the cakes are completely cool, place one of them on a serving plate and spread a layer of peanut butter truffles on top.

10. Place the other cake on top and cover the entire cake with the remaining truffle.

Ready! You now have a delicious Peanut Butter Truffle Chocolate Cake. Enjoy!
