Oh, you've just given me such a great idea!
My Girl Scout troop is going to repeat a very successful fund-raiser we did two years ago - Dessert of the Month Club. But the problem was that DD and I did almost all the cooking, because it had to be done on Sundays to be distributed at leader meetings on Mondays. But if we sell FROZEN desserts, we can just make them at our regular meetings and store them in the freezer until needed! We can't do the jars, they are too expensive, but individual cup-cake pies would be great.
Now I have to look for recipes that can be frozen either before or after baking. I'm excited!
