Lemon Blueberry Squares

I adapted this recipe from Kraft Foods, I made some changes that I think really enhanced this dessert. It is a great, refresing dessert!

48 Vanilla Wafers, crushed
3-4 Tablespoons melted butter
1 8oz pkg Cream Cheese, softened
1-1/2 cups cold milk
2 pkg. (3.4 oz. each) JELL-O Lemon Flavor Instant Pudding
2 Tbsp. lemon juice
1 tub (8 oz.) COOL WHIP Whipped Topping, thawed
1 1/2 cup fresh blueberries

Mix together crushed wafers and butter. Press into the bottom of 9x13 baking dish with a fork. Refridgerate.
Beat Cream cheese on high until creamy, add milk, pudding and lemon juice. Mix together until well blended. Fold in Cool Whip and 1 cup of blueberries.
Spread evenly onto prepared pie crust. Top with remaining blueberries.
Chill in refridgerator 3-4 hours or until set.
