Here is a good recipe that I got from my mother. A great thing is that you can substitute sugar free /fat free ingredients if you wish.
**********************************************
PRINCESS PUDDING

2 boxes JELL-O strawberry flavor
1 package Cool Whip topping
1 angel food cake, broken into bits
1 pkg frozen sliced strawberries, can use fresh in season

In advance, prepare one package of the JELLO per pkg directions. Set in a shallow pan, like a cake pan and let set.

When ready to prepare, mix together the angel food cake, Cool Whip topping and strawberries.
Pepare the second pkg of JELLO per directions, but do not allow to set. Pour liquid into mixture and stir in. Next, take the prepared JELLO and slice it into small cubes (about 1 inch). Mix the cubes into the preparation.
Now, spoon the mixture into a casserole or cake pan, and let set several hours before serving.
Everyone will love it.
