These Rice Krispy treats were very easy to make but a bit time consuming. It took just under two hours to make 20, but I had a young helper so possibly on your own it could be less. Also, doing one color at a time would save time. You can make these using M & Ms, which I would STRONGLY recommend if you want a decent blue Lego (I wasn't happy with mine), but my son's school has a strict nut-free policy, so we used Skittles and made our own blue.
1. Add your selected food coloring to some white icing. Mix enough the first time because you won't be able to match the color later. Three or four large dollops of icing will cover 4 or 5 Rice Krispy treats, depending on how thick you want the icing. If you decide to ice the entire treat, you will need a lot more icing. I chose to ice only the top because I thought it would be too messy for a bunch of preschoolers to pick up.
2. Ice your treat. Then apply the corresponding colored M&M or Skittle to the top. (This is a GREAT job for a kid).
3. If you use Skittles for the top and want blue, it can be done but they don't come out as nice in my opinion. I used yellow skittles and then iced them in blue. I found using a toothpick to touch up the icing was easier than a knife.
4. Serve. And sit back and enjoy the excitement!
