Pioneer Woman’s Peanut Butter Sheet Cake

Pioneer Woman’s Peanut Butter Sheet Cake is truly wonderful, it’s a new family favorite at our house.  It’s the same basic recipe as our Texas Sheet cake that I’ve made for years, with peanut butter substituted for the chocolate.  I did tweak it a bit, and here are the results.

 

Ingredients:

2 cups Sugar
1 teaspoon Baking Soda
2 cups Flour
1 teaspoon Salt
2 sticks Butter
1 cup Water
1 cup Peanut Butter (I use Jif Extra Crunchy)
½ cups Milk
1 teaspoon Vanilla
2 whole Eggs

Icing Ingredients:

1 stick Butter
½ cups Peanut Butter
6 teaspoons Milk (this wasn’t enough milk, start with this amount and add more, a teaspoon at a time until you get the right consistency, it took me a few more teaspoons to make it smooth)
1 pound box Powdered Sugar (Sift this so that you get smooth frosting)

Preparation:

Mix sugar, baking soda, flour and salt in a large bowl and sit aside.

In a saucepan combine butter, water and peanut butter and bring to a boil.  Pour over flour mixture, stirring constantly with a whisk so that it doesn’t lump.

Temper the wet ingredients by first adding the milk, then lightly beat two eggs and add them to the mixture with the vanilla.

The original recipe tells you to bake this in a 10x15 cookie sheet with sides or a jelly roll pan for 20 minutes in a 400 degree oven.

Our family loves thick cake so I bake it in a 9 x 13 pan, in a 350 degree oven for 35-40 minutes.  I would never bake a cake at 400 degrees, that’s just too hot.   If I baked this in jelly roll pan, I would still bake at 350 degrees and test after 20 minutes to see if it was done.

Icing Preparation:

Bring the butter, peanut butter and 6 teaspoons of milk to a boil in a saucepan.  Whisk in the sifted powdered sugar, and add additional milk, a teaspoon at a time until the icing is a creamy consistency.  Immediately pour the warm frosting over cooled cake.

Notes:  This cake is much better the 2nd day, even better the 3rd day, as it gets more moist as it ages in the covered cake pan.  I think I am going to make it using 1.5 cups of peanut butter in the cake batter next time to get a more intense peanut flavor, and hope that adding the extra half cup of peanut butter doesn’t mess with the consistency.

This would be amazing if you topped the icing with chopped peanuts or even better with chopped Reese Cups.  This is such a great recipe, it’s going into my Tried ‘n True Hall of Fame.
