Ingredients

For the Cookie 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 + 2 tbsp all-purpose flour

For Mix-ins

• 1½ cups rice krispie cereal
• ⅔ cup mini marshmallows
• flaked salt for topping

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 prepare for your cookies.

Step 2: Brown the Butter

1. In a medium saucepan, melt ½ cup of salted butter over medium heat.
2. Continue cooking past boiling until it turns golden brown and has a nutty aroma. Stir frequently to avoid burning.
3. Once browned, pour into a bowl and allow it to cool in the fridge or freezer for about 10 minutes.

Step 3: Mix the Wet Ingredients

1. In a mixing bowl, combine the cooled brown butter with both sugars (¾ cup brown sugar, ½ cup granulated sugar) until smooth.
2. Add in 1 large egg and 1 teaspoon vanilla, mixing on low speed for about 30 seconds.

Step 4: Combine Dry Ingredients

Slowly add in ½ tsp baking soda, ¾ tsp salt, and 1 cup + 2 tbsp all-purpose flour. Mix carefully to avoid overmixing.

Step 5: Add Rice Krispies and Marshmallows

Fold in 1½ cups rice krispie cereal followed by ⅔ cup mini marshmallows. Ensure they are evenly distributed throughout the dough.

Step 6: Scoop the Dough

Use a cookie scoop (about 3 tablespoons) to portion out dough balls onto your prepared baking sheet. Leave space between each cookie as they will spread while baking.

Step 7: Bake Your Cookies

Bake in preheated oven for 10-13 minutes or until edges are light golden brown. Keep an eye on them; overbaking can lead to losing that chewy center. Sprinkle with flaked salt before serving.

Now you’re ready to enjoy these amazing marshmallow crispy cookies!

Making perfect Marshmallow Crispy Cookies requires attention to detail. Here are some tips to ensure they turn out just right.

• Use fresh ingredients: Ensure your baking soda is fresh for optimal rise and texture in your cookies.

Common Mistakes to Avoid

Baking can be tricky, and even small mistakes can affect the outcome of your Marshmallow Crispy Cookies (Costco Copycat). Here are some common pitfalls to watch out for:

• Ignoring Butter Temperature: Using cold butter instead of melted brown butter can lead to cookies that don’t spread properly. Always ensure your butter is browned and cooled slightly before mixing.
• Overmixing the Dough: Overmixing can make the cookies tough instead of soft and chewy. Mix just until combined to keep them light and airy.
• Not Measuring Ingredients Accurately: Using too much flour or sugar can alter the texture and flavor. Use a kitchen scale or leveling technique for precise measurements.
• Skipping the Parchment Paper: Baking directly on a cookie sheet without parchment can cause sticking. Always line your baking sheets for easy removal and cleanup.
• Baking at Incorrect Temperature: An oven that’s too hot can burn the cookies while leaving them raw inside. Use an oven thermometer to ensure accurate temperature readings.
