Berry Layer:
2 cups frozen or fresh blueberries
1/2 cups white sugar
2 tbsp cornstarch
1/4 cup water
1 tbsp lemon juice (or frozen orange juice concentrate)

Oat Crust and Topping:
1 1/2 cup rolled oats
1 cup All Purpose Flour
3/4 cup brown sugar
1 1/2 tsp baking powder
pinch of salt (more if you use unsalted butter)
1 cup butter or margarine

In saucepan, stir together sugar and cornstarch, mix in water, blueberries and lemon juice (or orange).  Bring to a boil over medium heat.  Stir until sauce thickens.  Allow to cool.

In a large bowl, stir together oats, flour, sugar, baking powder and salt.  Drizzle melted butter (or marg).  Stir until ingredients combine.  Spread half of mixture on the bottom of a greased 8″ pan.  (I use an oval corningware dish)  Spread blueberry sauce over crust.  Crumble the remainder of the oat mixture on top of the blueberries.  Bake at 350º F for 40-45 mins or until golden and bubbling.  Let cool and cut into squares.
