Directions:
Preheat the oven to 350-degrees. Prepare a 9-inch-square baking pan with nonstick pan spray.

Combine the flour, sugar, poppy seeds, baking powder, baking soda, and salt in a large bowl. Add the margarine, egg whites, milk, lemon juice, zest, and vanilla. Mix just until the dry ingredients are moistened. Pour into the prepared pan. Bake 30 minutes, or until the cake springs back when the center is lightly pressed. Cool on a wire rack. Sift powdered sugar over the cake. Cut into 3-inch squares to serve. Recipe makes nine servings.
