GF Peanut Butter Sheet Cake

I made this once and promptly decided that I couldn't make it again without many, many people to share it with!

GF Peanut Butter Sheet cake

2 cups sugar

2 cups GF flour

½  tsp xantham gum ( If none in your flour)

2 eggs

1 tsp baking soda

1 cup dairy free sour cream or plain vanilla yogurt or applesauce

2/3 cup creamy peanut butter

1 cup nucoa

1 cup water

For the Glaze

½ cup nucoa

2/3 cup creamy peanut butter

6 tbs coconut milk

2 ½ powdered sugar

1 tsp vanilla

Preheat oven to 400 degrees.  In a bowl combine the sugar and the flour and xantham gum.  In a separate bowl mix eggs baking soda and sour cream well.  In a small saucepan combine peanut butter, butter and water.  Bring to a boil.  Stir the mixture into the flour mixture then add to the sour cream mixture.  Pour into and ungreased cookie sheet with sides, ie a jelly roll pan.  Bake 20 min or until done.  Cake is done when a toothpick comes out clean.  Mix the nucoa, peanut butter and coconut milk together in a sauce pan, bring to a boil stirring constantly.  Add powdered sugar and mix well off the heat.  Let it cook for a few minutes then add vanilla pour over cake while still warm.  Cool and serve.  Die in heaven.
