Reese’s Peanut Butter Cup Cake

For my daughter Brittany’s 14th birthday I wanted to make her a special cake. I thought about the idea of using her all time favourite chocolate bar the Reese Peanut Butter Cup. I decided to Google my thought and discovered of course that it wasn’t an original idea! Not too shocking with all the great minds out there in the world. Anyhow, I read through a couple of recipes and decided to basically follow the recipe from “The Idea Room” blog. The cake was loaded with PB cups and it was very decadent for sure – perfect for a special occasion. The only thing I did change is the way it was decorated. The original recipe covered the top of the cake with chopped up PB cups but I used different PB cups and chocolate and created some flowers with liquorice stems as decoration. I also used Reese’s pieces, PB filled hearts for the leaves and PB chips too.  Ahhh yes, there was no lack of chocolate or peanut butter in this cake!

INGREDIENTS

  • 1 devil’s food cake mix
  • 3 eggs
  • 1 cup of buttermilk (alternate is to add 1 tsp. of vinegar to your milk and let it sit for a few minutes)
  • 1/2 cup of vegetable oil
  • 2 cups of chopped peanut butter cups to go in the batter –which is about 2 packages of PB cups (with 3 individual cups inside)
  • another 2 packages of PB cups for decorating plus whatever else you want to use on top. I used some miniature Reese’s PB cups,PB hearts,Reese’s pieces and PB chips.
  • 8 oz. semi sweet chocolate, chopped up (original recipe used dark chocolate)
  • 1 cup of heavy cream
  • 1/2 cup of peanut butter

DIRECTIONS

  • Preheat oven to 350′ and coat two 9″ round pans with cooking spray.
  • In a large bowl, beat cake mix, eggs, buttermilk and vegetable oil on low for 30 seconds. Increase to med-high speed and beat for 2 minutes. Fold in the chopped PB cups.
  • Pour batter into pans and bake until a toothpick inserted comes out clean. For me this was approximately 40 minutes.
  • Cool cakes completely.

DIRECTIONS FOR ICING, which is apparently called ganache

  • Place chopped chocolate in a medium bowl. Bring cream to a boil and then pour over the chocolate. Whisk until the chocolate melts. Add the peanut butter and whisk till smooth.
  • Place one layer of cake on plate and pour 1 cup of icing on top.Spread evenly with a spatula. Add second layer and pour remaining icing on top and ice down the sides too.
  • Allow icing to set for a minute and gently decorate the top. You can cover the top with chopped PB cups or decorate like I did. Refrigerate for about an hour before serving.

I have got to say that I have never made ganache before and it is fabulous stuff! It went on so nicely and it looked so professional. I really loved it and I definitely think I will make it again.
