I made these this week for a meeting. I'm a fan of the rice crispie treat, and I remember seeing this last year around the net. I used the same recipe. 4 cups of marshmallows, 4 T. of melted butter. Stir both in a pan until melted, and then add 6 cups of cereal. I added another half to the recipe (6 c. of marshmallows, 6 T of butter, 9 cups of cereal) so these would be a little thicker in a 9x13 pan.
Use a buttered spatula to press these down. Once they harden (a few hours), cut them with a butered knife.
One thing I leanred.....don't over stir or the marshmallow treats will start melting.
I printed off a little tag. Everything is cutter with a tag.
