For the request for small size cakes, here's one that is TNT from the 70's.

Buttermilk Cake

1 cup all purpose flour
1/2 cup granulated sugar
1/4 teaspoon baking powder
1/4 teaspoon salt
1/2 teaspoon soda
1/4 cup oleo, softened
1/2 cup buttermilk
1 large egg
1 teaspoon vanilla
1 teaspoon butter flavoring

Combine dry ingredients. Add remaining ingredients and beat about 2 minutes on medium. Pour into sprayed or greased/floured 8 inch square pan. Bake at 350 degrees for 25-30 or until tests done.

It is delicious with or without a frosting.
