Peanut Butter Meltaway Cake

Preheat oven to 350 degrees.

For the cake:

In a saucepan over low heat, combine butter, cocoa powder, water, buttermilk, and eggs. Heat until it starts to bubble.

Remove from heat and add sugar, flour, baking soda and vanilla. Mix until smooth.

Pour into a greased 9×13 pan. Bake for 25 to 30 minutes or until a toothpick inserted in the middle comes out clean.

Cool completely.

Make the peanut butter layer by mixing together the peanut butter and vegetable oil. Spread over cake. Chill in the refrigerator for 20 minutes.

For the icing, heat icing ingredients together in a small saucepan until it bubbles. Spread on top of the peanut butter layer. Refrigerate.
