1 angel food cake (purchased or homemade)
2 (3 oz.) packages raspberry sugar-free gelatin
2 (3 oz.) packages strawberry sugar-free gelatin
1 (3 oz.) package instant sugar-free vanilla pudding
1 large carton fat-free whipped topping

Directions:
Prepare the 4 packages of gelatin, mixed together, according to the package directions. Spray a 9x13-inch dish lightly with non-stick cooking spray. Pour the prepared gelatin into the dish and chill. When the gelatin is set, cut it into bite-size cubes and keep it chilled until ready to use. Cut the cake into bite size cubes. Prepare the pudding according to package directions. Spread a few spoons of whipped topping across the bottom of a large bowl. Place half of the cake cubes on top of the whipped topping. Place half of the gelatin cubes on top of the cake. Spread half of the pudding over the gelatin cubes. Then spread on a layer of whipped topping. Repeat the layers, using the remainder of the cake cubes, gelatin cubes, and pudding. Finish with whipped topping. Cover with plastic wrap and refrigerate. Will keep for a couple of days in refrigerator.
