These soft-baked chewy M&M cookie bars are easy to make, kid-approved, and perfect for back-to-school mornings or after-school snacks. They feature a soft, chewy texture with colorful melty M&Ms in every bite.
Do not overmix the dough to avoid tough bars. Use brown sugar for moisture and chewiness. Watch baking time closely to keep bars soft. If bars brown too fast, tent with foil halfway through baking. Soften butter, do not melt. Chill dough for 15 minutes if too sticky to spread.
