Before making cake, wash and quarter a quart of strawberries.
In a bowl, add 3 Tbsp. sugar to the berries. Stir and let set, so the berries juice.
2 1/2 c. flour
2 tsp. baking powder
1/2 tsp. salt
1 c. sugar
1 c. milk
1 tsp. vanilla
2 tsp. butter
Stir together flour, baking powder and salt. In a separate bowl, beat eggs, sugar, milk and vanilla. Mix dry ingredients into egg mixture. Add melted butter and mix until combined.
Pour into a greased, 9x13 pan. Bake for 20-25 minutes at 375.
Top the cake with berries and cool whip. It is also good warm, right out of the oven, with berries and milk on top.
