This year for our son's third birthday, he knew exactly what he wanted. Well, he knew he wanted chocolate cake with peanut butter, it was up to me to find a suitable way to combine the two. Peanut Butter Poke Cake was what I came up with and man, was it good! A rich devil's food cake, topped with a layer of this peanut butter sauce and topped with a huge, thick layer of peanut butter-cream cheese-buttercream frosting. Tell me, that doesn't sound decadent?
