1/3 c. cocoa (powder)
1 7/8 c. flour
1 1/2 c. sugar
3 eggs
1 1/2 c. sour cream
1 1/2 tsp. baking soda
1 tsp. vanilla
3/4 tsp. salt

Beat eggs well, add sugar, then sour cream alternately with dry ingredients. Bake in 9"x13" pan in 350 degree oven for 30 to 35 minutes. I won 1st prize in a baking contest in high school with this recipe.
