|2 c. flour
1/2 c. sugar
1/4 c. packed brown sugar
2 1/2 tsp. baking powder
1/2 tsp. salt

Streusel topping: combine 1/3 c. sugar, ¼ c. flour and ¼ tsp. ground cinnamon in a small bowl. Cut in 3 Tbsp. butter or margarine with pastry blender until mixture resembles coarse crumbs.
Combine flour, 2 sugars, baking powder and salt in a large bowl. Stir in milk, egg, butter and lemon peel. Stir in 1 ½ cups white chips and blueberries.
