Low fat desserts?

Looking to cut the fat intake of my family and some calories too. I need some sweet treats I can serve my family that will not make them question if it is one of mom's "healthy diet desserts".

Here is a brownie recipe I make that my family doesn't have a clue that it is healthier than the ones I used to make.


1/2 cup unsweetened cocoa powder
4 ounces jar of prune baby food
3 egg whites
1 cup sugar
1 teaspoon salt
1 teaspoon vanilla
1/2 cup flour
1/4 cup walnuts (sometimes I add them sometimes I don't)


Mix everything together, spray an 8 x 8 pan with cooking spray and bake it for 30 minutes at 350.
