1 c. butter
2 c. granulated sugar
1 c. light brown sugar, packed
1/2 c. creamy peanut butter
5 eggs
1 tbsp. vanilla
3 c. cake flour
1/2 tsp. baking powder
1/2 tsp. salt
1/4 tsp. baking soda
1 c. milk

Cream butter and granulated sugar until light and fluffy. Add brown sugar and peanut butter and continue beating thoroughly. Add eggs, one at a time, beating well after each addition; add vanilla and blend well.

Sift together the dry ingredients and add alternately with the milk. Pour into a very large tube pan. Lightly grease the pan first. Bake at 325 degrees for around an hour or until it tests done. Frost, if desired, with the peanut butter frosting; however, it is delicious without the frosting.
