Melt butter and marshmallows. Use 30 seconds at a time in the microwave until melted, or melt on low heat on the stove.
Stir in Rice Krispie cereal and make sure mixture is thoroughly combined.
Take small spoonfuls and shape with hands into small egg shapes.
Let eggs cool. Takes about 20 - 40 Minutes.
Decorate eggs however you like. I used a little thin dab of gel and then added sprinkles.
