1 1/2 cups graham cracker crumbs (from 20 squares)
1/2 cup all-purpose flour
2 1/2 teaspoons baking powder
1/2 teaspoon salt
1/2 cup butter or margarine, softened
3/4 cup sugar
2 eggs
1 teaspoon vanilla extract
3/4 cup milk
Preheat oven to 350 degrees. Grease two 8-inch round cake pans.
Stir together the cracker crumbs, flour, baking powder and salt; set aside.
Beat the butter and sugar with an electric mixer at high speed until light and fluffy. Beat in the eggs, one at a time, and the vanilla. Alternately add crumb mixture and milk, beating after each addition.
Divide the batter between the pans. Bake 25 minutes, or until cake tests done. Cool in pans 15 minutes. Remove from pans and cool completely before filling and/or frosting as desired.
