1/2 c. flour
3/4 tsp. baking powder
1/2 c. low fat milk
5 lg. eggs, separated
1 tsp. vanilla
1 c. blackberries, rinsed & drained
1/2 tsp. cream of tartar

Mix flour and baking powder, add milk, yolks and vanilla. Gently stir in berries (mix slightly to break up a little). In a large bowl, whip egg whites and cream of tartar until foamy, fold batter into whites. Heat griddle to medium heat, brush lightly with butter (even non-stick surface). Spoon about 1/2 cup batter onto griddle, brown well on each side. Makes about 18 cakes.
