This Peanut Butter Poke Cake is much easier than you might think. When my son first asked for a peanut butter chocolate cake for his third birthday, I wasn't sure exactly how I'd go about it. I started playing with ideas in my head and poke cake seemed the best fit. This dessert is so easy and downright delicious!
Prepare and bake the Devil's Food cake as per package directions.
While the cake is baking, make the Peanut Butter Dessert Sauce. In a heavy-bottomed saucepan, over medium heat, melt the peanut butter and the condensed milk together. Pour in the water and mix until smooth. Remove from heat and stir in vanilla. Mix until fully combined. Set aside.
When the cake is finished baking, while still warm, poke holes about two inches apart all over the cake. Use the end of a wooden spoon, not a fork. It must be large enough to make an approximately 1/4 inch sized hole, so the peanut butter dessert sauce can easily sink into the cake. Pour the sauce over the cake and spread it over the cake so it reaches all the holes.
While that cools off, start on the peanut butter-cream cheese-buttercream frosting. Start by making a buttercream frosting. Using a hand mixer, slowly mix together the butter and icing sugar, along with the vanilla and heavy whipping cream. Once it is fully combined and fluffy, add in the cream cheese and peanut butter and mix until completely combined.
Once the cake has cooled, spread the frosting over top of the cake and decorate with Reese's Pieces. Keep leftovers in the fridge.
