First I started with fresh picked blueberries!
For this recipe you will need:
1 cup sugar
1 teaspoon baking powder
3 cups all-purpose flour
1 cup shortening
1/4 teaspoon salt
1 pinch of ground cinnamon
4 cups of fresh blueberries
1/2 cup sugar
3 teaspoons cornstarch
Preheat oven to 350 degrees. Grease a 9x13 inch pan.
In a medium bowl, stir together 1 cup sugar, 3 cups flour, and baking powder. Mix in salt and cinnamon, if desired. Use a fork or pastry cutter to blend in the shortening and egg. Dough will be crumbly. Pat half of the dough into the prepared pan.
In another bowl, stir together 1/2 cup sugar and 3 tsp. of cornstarch. Gently mix in the blueberries. Sprinkle the blueberry evenly over the crust. Crumble remaining dough over the berry layer.
Bake in a preheated oven for 45 minutes or until top is slightly brown. Cool completely before cutting into squares.
