Easy M&M Cookie Bars

Ashley Manila

Easy M&M Cookie Bars are soft, chewy, and so delicious! Loved by kids and adults, these are perfect for bake sales, potlucks, and holiday baking! Just like my brown butter M&M cookies, but so much easier!

Servings 1 Pan (9")

Ingredients

1 cup (227 grams) unsalted butter, melted until browned
1 cup (200 grams) light brown sugar, packed
1/4 cup (50 grams) granulated sugar
1 teaspoon pure vanilla extract
2 large eggs plus 1 large egg yolk, at room temperature
2 cups (254 grams) all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
1 cup (6 ounces) M&M candies, plus more for the top, if desired
Flaky Sea Salt, optional

Instructions

Preheat oven to 350 degrees (F). Line an 9x9-inch baking pan with parchment paper or aluminum foil. Spray lightly with non-stick spray and set aside.
In a saucepan over medium heat, melt the butter, then continue to cook it, stirring occasionally, until golden brown. Keep an eye here, you don't want burnt butter! Remove from heat and scrape the butter into a large heat proof mixing bowl.
Whisk in both sugars and mix until well combined. Stir in the vanilla. Then add in the eggs and egg yolk, beating until combined.
Using a rubber spatula, add in the flour, baking soda, and salt, mixing until just combined. Finally, fold in the M&Ms. Scrape the batter into the prepared pan.
Bake for 32 to 35 minutes, or until the edges are firm and golden. Press extra M&Ms on top of the warm cookie bars, if desired.
Cool in pan for at least 1 hour before cutting.
