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.

Description

This recipe starts with a dough mixing all-purpose flour, cornstarch, kosher salt, baking soda, and baking powder, combined with creamed unsalted butter, light brown sugar, granulated sugar, eggs, and pure vanilla extract. After mixing, M&M's and semi-sweet chocolate chips are folded in, blending color and chocolate flavor throughout the dough. The dough is pressed evenly into a parchment-lined 9×13-inch pan, topped with remaining M&M's, and sprinkled with flaky sea salt before baking at 350°F for 20 to 24 minutes.

The finished bars have a tender interior with crunchy edges, punctuated by pockets of melted chocolate chips and crunchy candy shells. The flaky sea salt enhances the sweetness without overpowering the balance. Letting the bars fully cool in the pan before cutting ensures clean slices. These bars are a convenient and visually appealing option for parties, snacks, or dessert.
