Cake:

2 cups all-purpose flour

1 teaspoon baking soda

1/2 teaspoon salt

1 3/4 cups white granulated sugar

1 cup butter or 2 sticks or 16 tablespoons

1 cup water

1/2 cup peanut butter, crunchy or smooth

1/2 cup buttermilk or can use regular milk (I use buttermilk)

1 teaspoon vanilla extract

2 eggs

In a large mixing bowl whisk together the flour, baking soda, salt and sugar.  Set aside.  Combine the butter, water and peanut butter in a pot on top of the stove and bring to a boil.  Remove from stove and slowly stir in milk and vanilla extract.  Pour into the bowl with flour mixture and stir with a spoon to mix.  Add the eggs and stir until all ingredients are wet and mixed.  Line a 15 x 10 inch baking pan with foil and spread mixture in pan.  I do not spray the foil before adding cake mixture.  Bake in a preheated 350 degree oven for 15 to 20 minutes until center tests done. Add frosting while cake is still hot.

Frosting:

1 stick butter or 1/2 cup or 8 tablespoons

1/4 cup peanut butter, crunchy or smooth

1/4 cup buttermilk or regular milk (I use buttermilk)

1 teaspoon vanilla extract

3 1/2 cups powdered sugar

Combine butter, peanut butter and milk in a pan on top of stove and bring to a boil.  Remove pan and add powdered sugar and vanilla extract stirring to melt all ingredients together. You can add more milk if frosting gets too thick.  Pour over cake and spread with a knife to cover entire cake.

Note:  You can add chopped peanuts to top of cake.

Makes 1 sheet cake.  Enjoy!
