Ingredients

These brown butter marshmallow crispy cookies are a crispy cookie loaded with rice krispies and chewy mini marshmallows with a caramel tasting brown butter dough. They are simple to make, no chilling required and taste better than Costco’s (yep! I said it)!

For the Dough

• ½ cup salted butter
• ¾ cup brown sugar
• ½ cup granulated sugar
• 1 large egg (room temperature)
• 1 teaspoon vanilla (this is a good time to use vanilla paste if you have it)
• ½ tsp baking soda
• ¾ tsp salt
• 1 cup all-purpose flour

For the Mix-Ins

• 1½ cups rice krispie cereal
• ⅔ cup mini marshmallows

For Topping

• Flaked salt

How to Make Marshmallow Crispy Cookies (Costco Copycat)

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking.

Step 2: Brown the Butter

In a medium saucepan, melt ½ cup salted butter. Continue cooking over medium heat until it foams and then turns golden brown with a nutty aroma. Stir frequently to avoid burning. Once browned, transfer it into a bowl and cool in the fridge or freezer for about 10 minutes.

Step 3: Mix the Dough

In a medium mixing bowl, combine the browned butter with both sugars. Add one room-temperature egg and one teaspoon of vanilla extract. Mix on low speed until smooth—about 30 seconds.

Step 4: Add Dry Ingredients

Gradually mix in ¾ tsp salt, ½ tsp baking soda, and 1 cup all-purpose flour. Be careful not to overmix; just combine until blended.

Step 5: Fold in Rice Krispies and Marshmallows

Gently fold in 1½ cups rice krispie cereal, followed by ⅔ cup mini marshmallows. Make sure they are evenly distributed throughout the dough.

Step 6: Scoop the Cookies

Using a cookie scoop (about 3 tablespoons), scoop large balls of dough onto your prepared baking sheet. Leave space between each ball as they spread during baking—4-5 cookies per sheet should be sufficient.

Step 7: Bake

Bake in the preheated oven for 10-13 minutes or until they turn light golden brown around the edges. Avoid overbaking to keep that chewy center intact. As soon as they come out of the oven, sprinkle with flaked salt for extra flavor.

Common Mistakes to Avoid

When making Marshmallow Crispy Cookies (Costco Copycat), avoiding common mistakes can ensure your cookies turn out perfectly every time.

• Overbaking the cookies – Keep a close eye on your cookies as they bake. They should be light golden brown around the edges. If you overbake, you’ll lose that chewy center.
• Not browning the butter properly – Browning butter adds depth of flavor. Ensure you cook it until it’s nutty and golden brown, stirring constantly to avoid burning.
• Using cold ingredients – Make sure your egg is at room temperature and the browned butter has cooled slightly before mixing. This helps achieve a smoother dough.
• Overmixing the dough – After adding flour, mix just until combined. Overmixing can lead to tough cookies instead of soft and chewy ones.
• Skipping the salt on top – Adding flaked salt before baking enhances flavor and balances sweetness. Don’t forget this simple but crucial step!
