Easter Egg Rice Treats

What did the rabbit say to the carrot?
It has been nice gnawing you.

 My sister came over the other week to make cookies and mini cheesecakes (which I still need to post pictures for!), and left the most wonderful leftovers.  Rice Krispies and Mini M&M's.  So, I thought I would make some Easter themed treats.

Here's what you need to make Easter Egg Rice Treats (for 6 large eggs):
3 tablespoons of butter, plus 2 tablespoons
8 oz of mini marshmallos
4 cups of Rice Krispies
egg shape cookie cutter/ egg shape cardboard cut out and a knife
wax paper
wooden spoon

Either buy some Iciing or make your own:
1-3 tablespoons of milk
2-3 cups of confectioner's sugar
1-2 drops of vanilla
food coloring

Optional toppings:
mini M&M's
colored sprinkles
