Thick and Chewy M&M Cookie Bars
Found on http://fantasticfamilyfavorites.blogspot.com
2 1/8 cups flour
1/2 tsp salt
1/2 tsp baking soda
12 tbsp butter (1 1/2 sticks), melted and cooled slightly
1 cup brown sugar
1/2 cup white sugar
1 large egg
1 large egg yolk
2 tsp vanilla extract
1 12oz bag M&M's, divided
1. Preheat the oven to 325 degrees. Adjust the oven rack to lower-middle position. Line a 9X13-inch baking pan with foil, letting the excess hang over the edges of the pan by about 1 inch so you can grab those edges and pull the bars from the pan after they have baked. Spray the foil-lined pan with nonstick cooking spray.
2. Mix the flour, salt, and baking soda together in medium bowl; set aside. Whisk the melted butter and sugars in a large bowl until combined. Add the egg, egg yolk, and vanilla and mix well. Using a rubber scraper, fold the dry ingredients into the egg mixture until just combined; do not over-mix. Fold in 1 cup of M&M's and turn the batter into the prepared pan, smoothing the top with the spatula. Sprinkle remaining M&M's on top and press in slightly.
3. Bake until the top is light golden brown, slightly firm to the touch, and edges start pulling away from sides of pan, 24-28 minutes. Cool on a wire rack to room temperature. Remove the bars from the pan by lifting the foil overhang and transfer them to a cutting board. Cut into squares and serve.
