CAKE - Cream butter until soft. Add sugar and stir until light and fluffy. Add eggs, one at a time, beating well after each is added. Sift dry ingredients. Alternately, add dry ingredients and sour cream, beginning and ending with flour mixture. Stir in vanilla.

TOPPING - In a separate bowl, mix together all four topping ingredients.
