These M&M Cookie Bars are thick, chewy, and packed with colorful M&M candies. With a soft center and golden edges, they're perfect for parties, bake sales, or a sweet treat any day of the week!
In a mixing bowl, whisk together melted butter and brown sugar until smooth. Add the egg and vanilla extract, mixing until well combined.
Stir in flour, baking powder, and salt until just combined. Fold in most of the M&M candies, reserving a handful for topping.
Spread the dough evenly into the prepared 8x8 inch baking dish using a spatula. Sprinkle the reserved M&M candies on top and gently press them into the dough.
Bake in the preheated oven at 350°F (175°C) for 20-25 minutes or until the edges are golden and a toothpick inserted into the center comes out with a few moist crumbs.
Allow the cookie bars to cool in the baking dish for 10 minutes. Transfer to a cooling rack to cool completely before slicing into bars. Enjoy!
