Peanut Butter Texas Sheet Cake

I don't know if this is popular in Dentin, Whitney, but I'm posting it for you anyways.

Cake ingredients:
2 sticks butter
¼ cup cocoa
1 cup water
½ cup buttermilk
2 cups sugar
2 cups flour
1 t. baking soda
2 eggs
1 ½ cups peanut butter

Frosting ingredients:
1 stick butter
½ cup cocoa
6 T. buttermilk
1 box powdered sugar
1 t. vanilla
1 cup chopped nuts

Combine the butter, cocoa, water, and buttermilk in a saucepan. Bring to a boil over medium/low heat. Pour it over the dry ingredients and mix well. Add beaten eggs to the mix quickly. Bake in a cookie sheet with sides at 350 degrees for 13 minutes.

Let cake cool for about 5 minutes and then spread the 1 ½ cups of peanut butter over the cake. Let peanut butter cool completely then make the frosting. Combine the butter, cocoa, and buttermilk in a saucepan and bring to a boil. Then add the sugar and vanilla and pour over the peanut butter with a spatula.
