Ultimate Chocolate Peanut Butter Explosion Cake

"This peanut butter cake is light and moist, perfectly layered with that creamy peanut butter mousse, chocolate fudge ganache and our favorite -- Reese's Peanut Butter Cups! My cup can keep running over with this. I won't complain. I love these stuffed candy layered loaf cakes! They are truly the ultimate! Enjoy those peanut butter and chocolate explosions!"
