July 4th Dessert by Sandra Lee

Hi Girlfriends, I found this scrumptious trifle dessert by Sandra Lee for July 4th. So you know how it is going to be so easy to make: "keep it simple", "keep it sweet" and "keep it semi-homemade."
1 box red velvet cake mix, about 18 ounces (if you can't find red velvet cake use 1 box chocolate cake plus a bottle of red food coloring)
1 (16-ounce) tub whipped topping
2 pints blueberries
1 pint strawberries, tops removed
Directions
Bake the red velvet cake mix according to package directions and allow to cool.
Using a serrated knife cut the red velvet cake into 1 inch square pieces and line the bottom of the trifle bowl with half of the cake squares.
Using a spatula, spread about a 2-inch layer of whipped topping on top of the cake squares.
Layer about 1 1/2 pints of the blueberries on top of whipped topping.
Layer the remaining cake pieces on top of the blueberries forming a second layer of cake.
Using a spatula, spread remaining whipped topping over the cakes pieces.
Decorate the perimeter with the strawberries; placing the strawberries cut side down. Sprinkle the remaining blueberries on top of the trifle inside the strawberry perimeter

Happy July 4th to all our girlfriends,
Denise & Gwen
