Recipe: Peanut Butter Cake - Nicole: I found a recipe. It is not a sponge cake

but regardless of that, here is an additional option besides dear Betsy'sponge cake:

Peanut Butter Cake

2 cups sifted cake flour
1 1/3 cups sugar
1 teaspoon salt
3 teaspoons baking powder
1/2 cup shortening
1/3 cup peanut butter
1 cup milk
2 medium whole eggs (unbeaten)

Sift dry ingredients together. Add shortening and peanut butter, 2/3 of the cup of milk. Beat two minutes with electric beater.

Then add other 1/3 cup of milk and the eggs. Then beat two more minutes (#3 speed).

Pour into layer cake pans.

Bake 30 to 35 minutes at 350 degrees.
