With Splenda - a cup of Splenda is 100 calories and a cup of sugar is 400. But even with sugar thats pretty low cal and you may not even need a whole cup.
I found a chocolate recipe online too so I'll try that.
Heres the basic recipe:
1 box diet jello powder (any flavor) (40 calories)
6 egg whites (or 12 tbs egg beaters whites) (150 calories)
1 cup splenda (100 calories)
** it also had 1/4 tsp cream of tartar and 1/4 tsp salt - I used that yesterday and it was nasty - really salty and I could taste the cream of tartar so I'm going to try it without.
Mix the jello & splenda in a bowl. Beat the whites with an electric mixer until they start to stiffen, then add the jello/Splenda mixture a tablespoon at a time. Beat until you have really stiff peaks.
Put 2 tbs mounds (or you can pipe it) on a parchment lined cookie sheet and bake at 250 degrees for 1.5 hours. Turn off oven and prop open oven door with a wooden spoon, let cookies stay in the oven until cool.
Makes approx 25.
