INSTRUCTIONS
1. Combine the cornstarch, sugar, water and blueberries in a medium saucepan. Cook over medium heat until the sauce thickens and bubbles, stirring regularly. This should take about 7 minutes. Cool. Combine the graham cracker crumbs, CINNAMON and butter. Press half of the crumbs into the bottom ofa lightly greased 9x13 pan.
2. Beat the cream cheese until soft. Gradually beat in the sugar and VANILLA. Gently fold in the whipped topping. Spread half over the crumbs. Spread half of the blueberry filling over the cream cheese layer, and then add another cheese layer and another blueberry layer. Sprinkle with the remaining crumbs. Chill overnight.
