These were sooooo yummy! Two of my boys didn't think they had much flavor, but after having one myself I overturned their opinion! I did have to freeze (in the deep freeze) the first layer for a good 2 hours or more, but that was no big deal, the blue Jell-o never got too firm in the fridge. I am going to hand this recipe off to our VBS snack crew since our theme this year is Operation Space. It should be perfect!
