Sour Cream Crumb Cake

1 1/2 cups flour
1/4 cup white sugar
1/4 packed brown sugar
2 tsp. baking powder
1/2 tsp. baking soda
1/4 tsp. salt
1 cup sour cream
2 eggs
1/4 cup butter, melted
1 tsp. vanilla

Crumb Topping:
4 Tbsp. all-purpose flour
2 Tbsp. butter
1/3 cup sugar
1 tsp. cinnamon

Preheat oven to 350 degrees F. Lightly grease an 8"x 8" pan.

Sift together the dry ingredients. In another bowl combine sour cream, eggs, butter and vanilla, mixing well. Add the sifted ingredients to the sour cream mixture. Stir just until all the dry ingredients are moistened. Batter will be lumpy. Spread in prepared pan.

Make crumb topping: Blend all ingredients until combined and sprinkle over the cake batter in the pan.

Bake at 350 F. for about 25-30 minutes or until browned and cake is beginning to pull away from sides of pan. Let cake cool in pan. Serve while slightly warm or cold.
