Lego Rice Krispie Treats are easy to make for your Lego lover. Great for a Lego birthday party, Lego themed allergy friendly treat for school, or just plain fun for Lego lovers!
Pour Rice Krispie cereal into a large mixing bowl. Set aside.
Melt butter in a saucepan over low heat. Once butter is melted, pour in mini marshmallows and stir constantly until marshmallows are completely melted and smooth.
Pour marshmallows over Rice Krispies and stir together until completely mixed together.
Scoop Rice Krispies into a lightly grease 9x13 pan. Press down using a piece of wax or parchment paper until flattened. Let cool completely before proceeding. You can pop them in the fridge for 5 minutes to speed up the cooling.
While the Rice Krispies are cooling, separate out the M&Ms into colors that match the icing you are using. You will need 6 of the same color per Lego Krispie.
Cut Rice Krispies into 18 rectangles. Squeeze some of the icing into a bowl. Dip the top of the Rice Krispie treat into the icing and use a butter knife to smooth it out. Place M&Ms on top in parallel rows of 3 while icing is still wet. Repeat with remaining Rice Krispie treats in varying colors of icing.
