  • Brown Sugar: A must-have for that deep caramel flavor and extra chewiness in your cookie bars.

  • All-Purpose Flour: This is the backbone of your cookie bars; it provides structure and texture.

  • Baking Soda: Helps your bars rise just enough to give them a delightful fluffiness without losing that chewy goodness.

Recipe preparation for Browned Butter Marshmallow Cookie Bars

How to Make Browned Butter Marshmallow Cookie Bars

Prepare Your Baking Dish: Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish with nonstick spray or line it with parchment paper for easy removal.

Brown the Butter: In a saucepan over medium heat, melt unsalted butter until golden brown and fragrant. Stir continuously to prevent burning; this should take about 5-7 minutes.

Mix Sugars Together: In a large mixing bowl, combine granulated sugar and brown sugar. Pour in the browned butter once slightly cooled and beat until well combined.

Add Dry Ingredients: Gradually fold in all-purpose flour and baking soda until just incorporated. Be careful not to overmix; we want soft, tender cookie bars!

Incorporate Marshmallows and Vanilla: Gently fold in mini marshmallows along with vanilla extract. You’ll start smelling that heavenly aroma already!

Bake to Perfection: Pour batter into prepared baking dish and spread evenly. Bake for 20-25 minutes until edges are golden brown but center remains soft. Let cool before cutting into squares.

With these steps, you’re sure to create Browned Butter Marshmallow Cookie Bars that will impress everyone who dares take a bite! Enjoy!
