Peanut Butter Sheet Cake

 Peanut butter sheet cake seemed to be very similar to a chocolate sheet cake recipe that I really liked.  I ended up making half of the recipe below and it perfectly fit my 1/4 sheet pan.  It is very peanut buttery and goes well with a glass of cold milk.

Peanut Butter Sheet Cake

Cake

2cups flour

2 cups sugar

1tsp. Salt

1 tsp baking soda

1cup peanut butter 

1 cup butter 

1cup water

1/2 cup buttermilk 

2 eggs 

Frosting

1/2 cup peanut butter

1/2 cup butter

6 Tbsp milk

1 tsp vanilla

4 cups icing sugar

Preheat oven to 350 F. Grease a half sheet pan, 13”x18”. Combine flour, sugar, salt and baking soda in a medium bowl and set aside. In a 2 quart sauce pan on medium heat, bring peanut butter, butter and water to a boil and set aside off of the heat.  Add buttermilk and beaten eggs to the peanut butter mixture and stir in.  Add in dry ingredients and mix to a smooth batter.  Pour into prepared pan and level off the batter.  Bake 20-25 minutes or until toothpick inserted in center comes out clean. (If you make a half recipe check cake at 15 minutes)

When cake is removed from oven immediately make the frosting. Heat the peanut butter and butter in a saucepan to melt.  Add milk and bring to a boil.  Remove from heat and add vanilla and icing sugar beating until smooth.  Pour the frosting onto the still warm cake and quickly spread frosting before it begins to set up.
