Marshmallow Crispy Brown Butter Cookies (Print Version)

Crispy, caramel-like cookies with browned butter, rice krispies and mini marshmallows that outshine the famous warehouse version.

# Ingredients:

→ Cookie Base

01 - 113.5g salted butter
02 - 165g brown sugar
03 - 100g granulated sugar
04 - 1 large egg, room temperature
05 - 1 teaspoon vanilla extract or vanilla paste
06 - 0.5 teaspoon baking soda
07 - 0.75 teaspoon salt
08 - 140g all-purpose flour

→ Mix-ins

09 - 43g rice krispie cereal
10 - 30g mini marshmallows
11 - Flaked salt for topping

# Steps:

01 - Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
02 - In a medium saucepan over medium heat, melt the butter. Continue cooking past the point of foaming until it turns golden brown and develops a nutty aroma. Stir continuously to prevent burning. Once browned, transfer to a bowl and chill in refrigerator or freezer for about 10 minutes to cool.
03 - In a medium mixing bowl, combine cooled brown butter with both brown and granulated sugars. Add the egg and vanilla, mixing on low speed until smooth, approximately 30 seconds.
04 - Slowly incorporate salt, baking soda, and flour, being careful not to overmix the dough.
05 - Gently fold in the rice krispies, followed by the mini marshmallows, distributing evenly throughout the dough.
06 - Scoop dough into large balls using a 3-tablespoon cookie scoop. Place only 4-5 cookies per baking sheet, allowing ample space for spreading.
07 - Bake cookies for 10-13 minutes until edges are light golden brown. Remove from oven, immediately sprinkle with flaked salt, and allow to cool. Cookies should have crisp edges and a chewy center.

# Notes:

01 - These cookies are intentionally thin and buttery. For a thicker cookie, add an additional 2 tablespoons of flour.
02 - When measuring flour without a scale, lightly spoon into measuring cup to ensure it's not packed for best results.
