It should look like this:

Mix self-rising flour with baking soda.

Add flour to wet mixture alternately with the buttermilk.

This is what it looks like all combined.

Bake in three layer cake pans at 350 for about 35 minutes. 

Allow to cool ten minutes in pan before turning out to cool completely.

For the Frosting:

Combine peanut butter, cream cheese, and powdered sugar with two tablespoon of milk.

You may need to add an extra tablespoon or two of milk if the mixture is too thick.

Or, if the mixture becomes too runny for your tastes, add extra powdered sugar.

Peanut Butter and Jelly Cake – Add a layer of jelly or fruit compote and make it a peanut butter and jelly cake.

Peanut Butter Cup – Add a layer of chocolate ganache or frosting, add chocolate chips to the cake mix, drizzle chocolate over the top. Crush up peanut butter cups and sprinkle across the top.

Nut Topping – From peanuts to pecans, or anything in between – crush up nuts and sprinkle across the top of the cake.
