How to Make Copycat Costco Marshmallow Crispy Cookies

Step 1: Melt the Butter and Marshmallows

Begin by melting the butter in a large saucepan over low heat. Once melted, add the marshmallows and stir continuously until they are completely melted and smooth. This mixture is the glue that holds your cookies together, so be patient for a smooth result.

Step 2: Mix in Vanilla, Sugar, and Salt

Remove the pan from heat, then stir in the vanilla extract, sugar, and salt. These ingredients add layers of flavor and balance the sweet and buttery notes perfectly.

Step 3: Incorporate the Crispy Rice Cereal

Gently fold in the crispy rice cereal with a spatula until every piece is coated evenly with the marshmallow mixture. The goal here is to preserve the crispiness while ensuring the cereal is well-bound.

Step 4: Shape and Cool

Transfer the mixture into a greased or parchment-lined baking dish, pressing it down evenly but not too tightly to maintain fluffiness. Allow it to cool at room temperature until set—it should be firm enough to cut into squares without crumbling.

Step 5: Cut and Serve

Once cooled, cut into your preferred size squares or rectangles. Serve fresh for the best chewy-crispy contrast, and enjoy the nostalgic taste of Copycat Costco Marshmallow Crispy Cookies that you made yourself!

Pro Tips for Making Copycat Costco Marshmallow Crispy Cookies

• Use Fresh Marshmallows: Fresh marshmallows melt more smoothly and yield the best chewy texture.
• Low Heat is Key: Melt butter and marshmallows on low heat to prevent burning and grainy texture.
• Don’t Press Too Hard: Slightly pressing the mixture helps maintain the light crispiness you love.
• Grease or Line Your Pan: Prevent sticking by using butter or parchment paper before pressing in the mixture.
• Store Properly: Keep cookies in an airtight container to maintain freshness and chewiness.

Garnishes

Enhance your cookies with a dusting of powdered sugar, a light drizzle of melted chocolate, or chopped toasted nuts on top before they set to add an extra touch of flavor and visual appeal.

Make Ahead and Storage

Storing Leftovers

Store leftover cookies in an airtight container at room temperature. They stay fresh and chewy for up to a week, perfect for snacking whenever the sweet craving hits.

Freezing

For longer storage, wrap cookies individually in plastic wrap and place them in a freezer-safe bag or container. They freeze well for up to three months. Thaw at room temperature before enjoying.

Reheating

If you prefer warm cookies, gently microwave them for 10-15 seconds or warm them briefly in the oven to revive that soft, gooey texture reminiscent of fresh baking.

FAQs

Can I use other types of cereal instead of crispy rice?

While crispy rice cereal is ideal for that classic texture, you can experiment with other cereals like cornflakes or puffed wheat for different crunch profiles, but it may alter the cookie’s traditional feel.

When freshly made, the cookies are soft and slightly sticky but become easier to handle once cooled and set. Using greased utensils and a light touch when pressing will help prevent sticking.

Can I make Copycat Costco Marshmallow Crispy Cookies vegan?

Yes! Substitute butter with coconut oil and use vegan marshmallows to keep the chewy texture while adhering to a vegan diet.
