M&M Cookie Bars
M&M Cookie Bars are a rich and chewy treat combining a classic cookie dough base loaded with colorful M&M's and semi-sweet chocolate chips. These bars bake with a lightly browned top and edges set, sprinkled with flaky sea salt to highlight the sweetness. The contrast of crisp edges and tender centers plus bursts of chocolate and candy pieces makes them ideal for sharing or a fun dessert option.
