Festive and chewy cookie bars loaded with red, white, and blue M&Ms, perfect for patriotic holidays and celebrations. Easy to make with pantry staples and loved by kids and adults alike.
Do not overmix once flour is added to keep bars tender. Fold M&Ms gently to prevent color bleeding. Let bars cool completely before slicing to avoid crumbling. For firmer bars, refrigerate for 15 minutes before cutting. Rotate pan halfway through baking for even browning.
