Ingredients
(You can also use a regular cookie cutter without the green food coloring for non-Creeper shapes)

Melt the butter in a large pot over low heat. (Be careful not to burn it.)

Add the marshmallows and stir until melted, then remove from heat. (The photo shows large marshmallows, but mini ones melt more easily if you have them.)

Add 1-2 drops of food coloring, and once it turns green, add the Rice Krispies and mix quickly to coat evenly.

Transfer to a greased 9x13-inch Pyrex dish and press down with parchment or wax paper.

Refrigerate for about 30 minutes to set.

Cut into desired sizes with a knife. If you want squares, trim off the curved edges.

Draw a Creeper face with icing. (A chocolate pen works too.)

Once the icing is dry, they're ready! Even a makeshift Creeper will delight the kids!
