A giant M&M cookie cake that’s chewy with slightly crispy edges, perfect for celebrating the first day of school. Easy to make with simple pantry ingredients and loved by kids and adults alike.
Do not overmix the dough to avoid toughness. Use room temperature butter and eggs for best results. Press M&Ms on top before baking for a colorful finish. Cool completely before slicing for cleaner cuts. Dough can be refrigerated up to 24 hours; add extra baking time if baking chilled.
