Get ready to discover how simple it is to bring the joy of those coveted “Marshmallow Crispy Cookies Costco Copycat” right to your home oven.

Ingredients:

• For the Cookies:
• 2 ½ cups (300g) all-purpose flour
• 1 teaspoon baking soda
• 1 teaspoon fine sea salt
• 1 cup (226g) unsalted butter, softened to room temperature
• 1 cup (200g) granulated sugar
• 1 cup (220g) light brown sugar, firmly packed
• 2 large eggs, at room temperature
• 2 teaspoons pure vanilla extract
• 2 cups (about 5 ounces) mini marshmallows, plus more for topping
• 3 cups (about 3 ounces) crispy rice cereal
• For the Marshmallow Topping & Extra Crunch:
• 1 cup (about 2.5 ounces) mini marshmallows
• 2 tablespoons unsalted butter
• ½ teaspoon pure vanilla extract
• ½ cup (about 0.5 ounces) crispy rice cereal, for garnish

Preparing the Cookie Dough for Your “Marshmallow Crispy Cookies Costco Copycat”

1. Preheat Your Oven and Prep Baking Sheets: First things first, let’s get that oven ready! Preheat your oven to a cozy 375°F (190°C). While it’s warming up, line two large baking sheets with parchment paper or silicone baking mats. This is super important to prevent sticking and ensure your beautiful “Marshmallow Crispy Cookies Costco Copycat” lift off easily. Having them ready means you can quickly transfer your scooped dough onto them once it’s mixed.
2. Whisk Together Dry Ingredients: In a medium bowl, whisk together your 2 ½ cups of all-purpose flour, 1 teaspoon of baking soda, and 1 teaspoon of fine sea salt. Make sure these dry ingredients are thoroughly combined. The baking soda is our leavening agent, giving the cookies a lovely lift, and the salt balances out the sweetness. Whisking ensures they are evenly distributed, so every cookie gets the right amount of flavor and rise. Set this bowl aside for a moment.
3. Cream Butter and Sugars: Now, in a large bowl, ideally using a stand mixer with the paddle attachment or a hand mixer, combine your 1 cup of softened unsalted butter with 1 cup of granulated sugar and 1 cup of firmly packed light brown sugar. Beat these ingredients together on medium-high speed for about 2-3 minutes. You’re looking for a light, fluffy, and creamy texture. This creaming process incorporates air into the mixture, which contributes to the ultimate soft and chewy texture of your “Marshmallow Crispy Cookies Costco Copycat.” Scrape down the sides of the bowl as needed to ensure everything is well combined.
4. Incorporate Eggs and Vanilla: Reduce your mixer speed to low. Add one large egg at a time, mixing well after each addition until just combined. Don’t rush this step; allow each egg to fully integrate into the butter and sugar mixture. Once both eggs are in, add the 2 teaspoons of pure vanilla extract. Increase the speed to medium and beat for another minute until the mixture is cohesive and smooth. Vanilla is key for that classic cookie flavor!
5. Gradually Add Dry Ingredients: With your mixer still on low speed, slowly add the dry ingredient mixture to the wet ingredients. Mix until just combined. It’s crucial not to overmix at this stage; overmixing the flour can develop too much gluten, resulting in a tough, dense cookie. As soon as you see no more streaks of dry flour, stop the mixer. We want our “Marshmallow Crispy Cookies Costco Copycat” to be tender, not tough!
6. Gently Fold in Marshmallows and Crispy Cereal: This is where the magic really starts to happen for our “Marshmallow Crispy Cookies Costco Copycat.” Remove the bowl from the mixer and, using a large rubber spatula, gently fold in 2 cups of mini marshmallows and 3 cups of crispy rice cereal. Be very careful not to crush the cereal too much; we want those delightful crispy bits! The goal is to evenly distribute these wonderful additions throughout the dough without deflating the mixture. The marshmallows will give us those beautiful gooey pockets when baked, and the cereal provides that fantastic textural contrast.
7. Chill the Dough (Optional but Recommended for Best Results): While you can bake these cookies immediately, I highly recommend chilling the dough for at least 30 minutes in the refrigerator, or even up to 2 hours. Chilling helps the butter solidify, which prevents the cookies from spreading too much in the oven, leading to thicker, chewier cookies. It also allows the flavors to meld beautifully. If you’re making large batches of “Marshmallow Crispy Cookies Costco Copycat” like the store, chilling is essential for consistency.

Baking the “Marshmallow Crispy Cookies Costco Copycat”

8. Scoop the Cookie Dough: Once your dough is chilled and your oven is preheated, it’s time to scoop! Using a large cookie scoop (about 2-3 tablespoons per cookie), drop mounds of dough onto your prepared baking sheets. Make sure to leave about 2 inches of space between each cookie, as they will spread. For that classic bakery-style “Marshmallow Crispy Cookies Costco Copycat” look, you might want to break off a few extra mini marshmallows and gently press them into the tops of the dough balls before baking. This helps ensure those lovely toasted marshmallow bits are visible on the surface.
9. Bake the Cookies: Place one baking sheet at a time into your preheated oven. Bake for 10-14 minutes. The exact baking time can vary depending on your oven, so keep a close eye on them. You’re looking for cookies that have golden-brown edges but are still slightly pale and soft in the center. Remember, cookies continue to cook for a minute or two after they’re removed from the oven, so slightly underbaking them will give you that perfect soft and chewy texture that we adore in a “Marshmallow Crispy Cookies Costco Copycat.”
10. Cool on Baking Sheets: Once baked, remove the baking sheets from the oven. Let the cookies cool on the baking sheets for about 5-10 minutes. This critical step allows them to set up properly. They’ll be quite delicate and gooey right out of the oven, especially with those melted marshmallow pockets! If you try to move them too soon, they might fall apart.
11. Transfer to a Wire Rack: After the initial cooling period on the baking sheet, carefully transfer the cookies to a wire rack to cool completely. This ensures air circulation all around the cookies, preventing them from becoming soggy on the bottom and helping them achieve that ideal “Marshmallow Crispy Cookies Costco Copycat” chewiness.

Finishing Touches: The Signature Marshmallow & Crispy Topping

12. Prepare the Marshmallow Topping: While your cookies are cooling, let’s make that irresistible marshmallow topping. In a microwave-safe bowl, combine 1 cup of mini marshmallows, 2 tablespoons of unsalted butter, and ½ teaspoon of pure vanilla extract. Microwave on high for 30-second intervals, stirring well after each, until the mixture is completely melted and smooth. This usually takes about 1 to 2 minutes total. Be careful not to overheat, as marshmallows can seize up. Stir vigorously until it’s a luscious, pourable glaze. If it feels too thick, you can add a tiny splash of milk (about half a teaspoon) to reach your desired drizzling consistency. This topping is what truly elevates these from ordinary cookies to “Marshmallow Crispy Cookies Costco Copycat” masterpieces!
13. Drizzle and Garnish: Once your cookies are mostly cooled (warm is okay, but not hot), it’s time for the grand finale! Using a spoon or a whisk, generously drizzle the warm marshmallow glaze over each cookie. You can do a simple zigzag pattern or a more free-form swirl – whatever you fancy.
14. Add the Extra Crispy Crunch: Immediately after drizzling, sprinkle the remaining ½ cup of crispy rice cereal over the wet marshmallow glaze on each cookie. The stickiness of the glaze will help the cereal adhere, adding another layer of texture and making these “Marshmallow Crispy Cookies Costco Copycat” truly irresistible. Work quickly, as the marshmallow glaze sets relatively fast.
15. Allow to Set: Let the marshmallow topping set completely before storing the cookies. This might take another 15-30 minutes, depending on the warmth of your kitchen. The topping will firm up into a delightfully chewy, slightly sticky layer.
16. Storage Tips: Store your completed “Marshmallow Crispy Cookies Costco Copycat” in an airtight container at room temperature for up to 3-4 days. While they are best enjoyed fresh, the marshmallow and crispy cereal combination holds up surprisingly well. If you stack them, you might want to place a piece of parchment paper between layers to prevent sticking, especially if the marshmallow glaze is still a little soft. These cookies are a celebration of texture and flavor, combining soft, chewy cookie goodness with gooey pockets of melted marshmallow and plenty of crispiness. Enjoy every single bite of your homemade “Marshmallow Crispy Cookies Costco Copycat” creation! You’ve just made something truly special and incredibly delicious.

For a truly decadent experience, try serving them slightly warm with a scoop of vanilla bean ice cream – the way the warm cookie melds with the cold ice cream is pure bliss. Alternatively, a simple drizzle of melted milk chocolate or a dark chocolate ganache can transform them into an elegant dessert, perfect for entertaining.

Imagine a plate of these for a birthday party, or packed into lunchboxes for a delightful midday surprise! You could even experiment with different flavored marshmallows; imagine a strawberry marshmallow version, or perhaps a chocolate-swirled marshmallow for an extra cocoa kick. For those who love a bit of nuttiness, a handful of finely chopped pecans or walnuts folded into the dough would add another layer of flavor and crunch. Or, if you want to push the boundaries, try making mini versions and sandwiching them together with a dollop of cream cheese frosting – a truly next-level treat that will impress absolutely everyone. The important thing is to have fun with it and make them your own!
