2 c. sifted flour
2 c. light brown sugar, firmly packed
1/2 c. butter
1/3 c. sifted flour
1 tsp. baking soda
1 tsp. cinnamon
1 egg
1 c. buttermilk
1 tsp. vanilla

Mix flour and brown sugar. Cut butter in until mixture resembles coarse meal. Set aside 1/2 cup of this mixture to be used for topping. To remaining flour mixture, add 1/3 cup flour, baking soda, and cinnamon. Mix well. Then add egg and buttermilk. Mix only until dry ingredients are well moistened. Pour into buttered 9 x 9 x 2 inch pan. Mix the 1/2 cup sugar mixture that was set aside (add 1/4 cup brown sugar, if necessary); sprinkle over the top. Bake in 350 degree oven for 50 to 55 minutes.

(For a yellow coffee cake, use 1 1/3 cups white sugar, instead of brown sugar and omit cinnamon.)
