Costco Cookies Recipe

Introduction

This Costco Copycat cookie recipe brings the beloved crunchy-chewy treat right to your kitchen. Featuring browned butter, crispy rice cereal, and mini marshmallows, these cookies offer a perfect balance of flavors and textures that will satisfy any sweet tooth.

Ingredients

• ½ cup salted butter
• ¾ cup brown sugar
• ½ cup granulated sugar
• 1 large egg (room temperature)
• 1 teaspoon vanilla (vanilla paste works great here)
• ½ teaspoon baking soda
• ¾ teaspoon salt
• 1 cup all-purpose flour
• 1½ cups Rice Krispie cereal
• ⅔ cup mini marshmallows
• Flaked salt for topping

Instructions

1. Step 1: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Step 2: In a medium saucepan, melt the butter over medium heat. Continue cooking past the boiling point until it turns golden brown and smells nutty, stirring constantly to avoid burning. Once browned, transfer the butter to a bowl and chill in the fridge or freezer for about 10 minutes.
3. Step 3: In a mixing bowl, combine the cooled browned butter with brown sugar and granulated sugar. Add the egg and vanilla, mixing on low speed until smooth, about 30 seconds.
4. Step 4: Gradually add the salt, baking soda, and flour, mixing carefully to avoid overworking the dough.
5. Step 5: Gently fold in the Rice Krispies cereal followed by the mini marshmallows.
6. Step 6: Using a 3-tablespoon scoop or spoon, portion the dough into large balls. Place 4 to 5 cookies on each prepared baking sheet, spacing them well to allow for spreading.
7. Step 7: Bake for 10 to 13 minutes, or until the edges turn light golden brown. Avoid overbaking to keep a chewy center. Immediately sprinkle flaked salt on top after removing from the oven.

Tips & Variations

• For deeper flavor, use vanilla paste instead of extract.
• Be attentive while browning butter to prevent burning; removing it from heat just as it turns golden will enhance the nutty aroma.
• Try adding chopped nuts or chocolate chips for extra texture and taste.
• If you prefer a softer cookie, slightly underbake and let the cookies cool on the baking sheet.

Storage

Store cookies in an airtight container at room temperature for up to 4 days. For longer storage, freeze the cookies in a sealed container or bag for up to 3 months. To reheat, warm gently in a low oven or microwave for a few seconds to restore softness and flavor.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Can I use unsalted butter instead of salted?

Will these cookies be crunchy or chewy?

These cookies are designed to have a chewy center with slightly crispy edges, complemented by the crunch from the Rice Krispies and softness of the mini marshmallows.

Ingredients

Scale 1x2x3x

Main Ingredients

• ½ cup salted butter
• ¾ cup brown sugar
• ½ cup granulated sugar
• 1 large egg (room temperature)
• 1 teaspoon vanilla extract or vanilla paste
• ½ teaspoon baking soda
• ¾ teaspoon salt
• 1 cup all-purpose flour

Mix-ins and Topping

• 1½ cups Rice Krispie cereal
• ⅔ cup mini marshmallows
• Flaked salt for topping

Instructions

1. Preheat Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper to prevent sticking and help with even baking.
2. Browning the Butter: In a medium saucepan over medium heat, melt ½ cup salted butter and continue cooking past melting until it foams, then turns a golden brown color with a nutty aroma. Stir continuously and watch carefully to avoid burning. Once browned, transfer the butter to a bowl and chill in the fridge or freezer for about 10 minutes to cool.
3. Mix Butter and Sugars: In a medium mixing bowl, combine the cooled browned butter with ¾ cup brown sugar and ½ cup granulated sugar. Add 1 large room-temperature egg and 1 teaspoon vanilla. Mix on low speed until smooth and well combined, about 30 seconds.
4. Add Dry Ingredients: Gradually add ¾ teaspoon salt, ½ teaspoon baking soda, and 1 cup all-purpose flour to the wet ingredients. Mix slowly and carefully to avoid overmixing the dough.
5. Fold in Extras: Gently fold in 1½ cups Rice Krispie cereal, then fold in ⅔ cup mini marshmallows, ensuring they are evenly distributed without crushing them.
6. Scoop the Dough: Using a 3 tablespoon cookie scoop or equivalent spoon, scoop large balls of dough onto the prepared baking sheet, spacing 4-5 cookies per sheet as they spread thin while baking.
7. Bake: Bake the cookies for 10 to 13 minutes, looking for a light golden brown around the edges while keeping the center chewy. Avoid overbaking to retain their chewy texture.
8. Finish and Serve: As soon as the cookies come out of the oven, sprinkle them with flaked salt to enhance the flavors. Let cool slightly before serving.

Notes

• Using vanilla paste can enhance the depth of vanilla flavor.
• Watch the butter closely when browning to prevent it from burning.
• Allow the dough to cool slightly after browning the butter to prevent cooking the egg during mixing.
• Do not overmix the dough once flour is added to keep cookies tender.
• Large cookie scoops make for the classic chewy, thin cookie texture.
• Flaked salt adds a delightful contrast to the sweetness.
