vegan marshmallows Crispy Cookies (Costco Copycat): A Sweet Symphony of Flavors
Welcome to your next favorite cookie experience! These vegan marshmallows Crispy Cookies combine everything we love about desserts: the buttery richness enhanced by a caramel-like flavor from our brown butter, the satisfying crunch of rice krispies, and those sweet little bursts of joy from mini vegan marshmallows. Once you try these beauties, you’ll understand why they might just become your go-to dessert.

Ingredients:
Before we embark on this delicious journey together, let’s gather our ingredients. Each one plays a vital role in crafting these extraordinary cookies.
- ½ cup salted butter: This is where we start creating our rich base flavor! Salted butter contributes not only moisture but also depth; its inherent saltiness balances the sweetness beautifully. When browning the butter—a crucial step—you’ll get those nutty aromas wafting through your kitchen as it transforms into liquid gold. If you’re looking for a dairy-free alternative, consider using vegan butter; just make sure it has a similar fat content for best results.
- ¾ cup brown sugar: Ahh, brown sugar—a must-have for that caramelized flavor profile we’re aiming for! Its molasses content gives these cookies their lovely chewiness and adds complexity to every bite. When measuring this sugar, be sure to pack it firmly into your measuring cup to capture all that delicious sweetness.
- ½ cup granulated sugar: This ingredient provides sweetness and helps achieve that delightful crispness on the edges of our cookies. The combination of granulated sugar with brown sugar creates layers of texture that elevate each mouthful into something truly special.
- 1 large egg (room temperature): Eggs provide structure and moisture in baking; however, since we are keeping this recipe vegan-friendly, you can use a flax egg instead! Simply mix 1 tablespoon of ground flaxseed with 3 tablespoons of water and let it sit until gelatinous—this will help bind everything beautifully.
- 1 teaspoon vanilla: Vanilla extract or paste adds warmth and aroma—an essential element in baking! If you’re fortunate enough to have vanilla bean paste on hand, now is the perfect time to use it; its specks will add visual appeal as well as intense flavor.
- ½ tsp baking soda: This little powerhouse acts as our leavening agent—it helps create those wonderful airy pockets in our cookies while also enhancing browning due to its reaction with sugars during baking. Just make sure it’s fresh; expired baking soda won’t give you that desired lift!
- ¾ tsp salt: While we’re using salted butter here, adding extra salt amplifies all other flavors and balances sweetness perfectly. It’s like adding a pinch of magic—don’t skip this step!
- 1 cup all-purpose flour: The backbone of our cookie dough! Flour provides structure and absorbs moisture during baking. For best results, scoop your flour gently into your measuring cup without packing it down—this ensures your cookies won’t turn out dry!
- 1½ cups rice krispie cereal: This ingredient introduces delightful crunch! The lightness of rice krispies contrasts beautifully with the chewy texture from our marshmallows. Feel free to choose gluten-free options if needed—the joy is in customization here!
- ⅔ cup mini vegan marshmallows: What would these cookies be without those adorable little puffs? They melt slightly during baking yet retain their shape enough to provide chewy bites throughout every cookie. Look for brands that use plant-based ingredients to ensure they meet your needs.
- Flaked salt for topping: A sprinkle on top before serving enhances not only aesthetics but also flavor—it’s that final touch that makes each bite sing!

Equipment You’ll Need:
Having the right tools can make all the difference in ensuring your baking experience is smooth and enjoyable. While these aren’t ingredients per se, they play essential roles in helping us create something wonderful together.
- Mixing bowls – A sturdy set of mixing bowls is crucial for combining ingredients effectively! Opt for glass or metal types; they conduct heat well if you’re working with warm mixtures like browned butter.
- Silicone spatula – When folding in delicate ingredients like marshmallows or rice krispies, a silicone spatula is perfect—it prevents breaking them apart while ensuring everything is well incorporated without leaving any bits behind.
- Baking sheet lined with parchment paper – This non-stick surface makes transferring your beautiful creations effortless while preventing them from spreading too much during baking.
- Cookie scoop (3 TBSP) – Investing in a good cookie scoop ensures uniformity in size across all your cookies—and who doesn’t love perfectly shaped treats? Plus, it saves time when portioning out dough!
Now that we’ve gathered our ingredients and prepared our equipment let’s dive into preparing these delightful vegan marshmallows Crispy Cookies (Costco Copycat).
Step 1: Preheat Your Oven & Prepare Your Baking Sheet
First things first—let’s get that oven preheating to 350°F (175°C). Preheating isn’t just a suggestion; it’s crucial because starting off at the right temperature ensures even baking throughout each cookie batch. While that’s happening, line your baking sheet with parchment paper—it prevents sticking and makes cleanup a breeze later on.
Step 2: Brown Your Butter
Next up is one of my favorite parts—browning the butter! Take your ½ cup salted butter and melt it gently over medium heat in a medium saucepan. As it melts away into liquid gold, keep stirring continuously because this step requires patience—it can quickly go from perfectly browned to burnt if you’re not careful! Watch closely as it bubbles and foams before transforming into an amber hue while releasing a nutty aroma reminiscent of cozy kitchens filled with nostalgia-inducing scents. Once you’ve reached that gorgeous golden shade (about 5 minutes), pour your brown butter into a bowl and let it cool slightly in either the fridge or freezer for about 10 minutes—this cooling period helps prevent cooking the egg when mixed later.
Step 3: Combine Sugars & Mix Smoothly
In another mixing bowl (or using the same one after letting it cool), combine your cooled brown butter along with both sugars—brown sugar first followed by granulated sugar—and mix them together until smooth using either an electric mixer on low speed or whisking vigorously by hand for about 30 seconds. This process creates air pockets which contribute to lightness later on! Afterward comes adding in room-temperature egg (or flax egg) along with vanilla extract/paste—you should see everything blend seamlessly into what resembles melted caramel sauce at this point—that’s what we want!
Step 4: Incorporate Dry Ingredients
Now let’s take things up another notch by slowly folding in salt, baking soda, and flour—all essential components working harmoniously together here—not only do they enhance flavor but also provide structure necessary during baking time! Be gentle during this step—overmixing will develop gluten leading us toward tough cookies instead of soft chews we’re aiming for so stop as soon as you see no dry streaks left behind.
I can’t wait for you to continue creating these incredible vegan marshmallows Crispy Cookies (Costco Copycat). Trust me when I say they’ll be worth every moment spent preparing them—we’re almost there!
Step 5: Folding in the Crunch and Sweetness
Now comes the moment where your cookie dough transforms into something truly magical. You’ll want to gently fold in the rice krispies first, followed by the mini vegan marshmallows. This is a crucial step because it introduces that delightful crunch and chewy texture that makes these cookies so special. As you incorporate the rice krispies, you’ll notice how they add a wonderful lightness and an airy quality to your dough. Just think about it: each bite will be a symphony of flavors — the soft, sweet marshmallows melting against the crispy cereal. Trust me when I say, this combination is utterly intoxicating!
When folding in the marshmallows, be gentle! You want them evenly distributed throughout the dough without breaking them apart too much. If you overmix at this stage, you risk deflating that airiness we’ve worked so hard to achieve, which would lead to denser cookies than intended. Just use a rubber spatula or a wooden spoon and fold with care until everything is mixed together beautifully. It’s all about maintaining that perfect balance of textures.
Step 6: Scooping Perfection
Now that your dough is ready, it’s time to get scooping! I recommend using a 3-tablespoon cookie scoop for this part because it ensures uniformity and makes your life so much easier. Portioning out consistent cookie sizes isn’t just about aesthetics; it also guarantees even baking. Picture this: each cookie will be perfectly golden brown on the edges while still remaining soft and chewy in the center. I like to place four to five cookie dough balls on each baking sheet, allowing enough space between them since they will spread during baking.
While you’re scooping, take a moment to appreciate how beautiful your mixture looks — those little specks of caramelized butter mingling with marshmallow bits are just begging to be baked into something extraordinary! Plus, don’t worry if there are some irregular shapes; each one adds its unique charm to your batch! And remember, don’t rush this step; savoring these moments in the kitchen is what makes cooking such a joy.
Step 7: Baking Your Masterpieces
With your oven preheated to 350°F (that’s about 175°C), it’s time for those dough balls to transform into glorious cookies! Slide your baking sheet into the oven and set your timer for 10-13 minutes. This is where the magic happens! During this time, you’ll witness the cookies puff up slightly before settling down into that classic crispy edge and chewy center we all crave. Keep an eye on them after about 10 minutes; you’re looking for a lovely light golden brown around the edges while the centers remain slightly softer.
Here’s where understanding your oven’s quirks comes into play: if you have a convection setting, those cookies might bake faster than expected, so keep an eye out! It’s absolutely paramount not to overbake these beauties; if you do, you’ll lose that heavenly chewiness in the center that makes them truly extraordinary. Remember, they will continue to cook slightly after being removed from the oven due to residual heat — so if they look just shy of perfect when you pull them out at around 10-11 minutes, know you’ve made a wise decision!
Step 8: The Finishing Touches
Once you’ve pulled those gorgeous vegan marshmallows crispy cookies from the oven, it’s essential to sprinkle them with flaked salt right away while they’re still warm. This small but significant touch enhances their sweetness and balances out all those rich flavors beautifully. Imagine biting into one of these cookies only to hit that contrasting burst of salty goodness—it’s like fireworks on your taste buds! The warmth from the cookies will allow that salt to adhere just perfectly without being overwhelming.
After sprinkling with salt, give them a few minutes on the baking sheet before transferring them onto a wire rack; this helps them firm up just enough so they’re not too delicate when moving them around. Patience here is key; letting them cool on the rack for another few minutes allows their structure to stabilize while intensifying those flavors even more as they settle down. I promise you; it’s worth every second of waiting!

The aroma wafting through your kitchen is simply irresistible, beckoning friends or family members who might be wandering nearby—be prepared for compliments! Whether enjoyed fresh from the oven or stored away for later indulgence (if they last that long!), each bite will transport you straight back to carefree childhood days filled with sugary snacks and laughter.
If by chance any make it past day one (and let’s be real—they probably won’t!), simply store them in an airtight container at room temperature for up to five days—if you’re lucky enough not to eat them all sooner! So go ahead, gather loved ones around, share stories over warm cookies paired with a glass of almond milk or coconut cream—it’s all about creating moments filled with joy and connection through food.
These vegan marshmallows crispy cookies are more than just a treat; they are an experience waiting to happen—one that evokes nostalgia while embracing modern flavors.

Storage and Enjoyment Tips for Your vegan marshmallows Crispy Cookies (Costco Copycat)
Now that you’ve whipped up a batch of these utterly enchanting vegan marshmallows crispy cookies, it’s time to bask in the warm glow of your baking success! I know you’re just itching to dive into that symphony of flavors and textures—crunchy, chewy, and oh-so-delicious. But let’s talk storage because we want our cookie magic to last as long as possible. These delightful treats can be stored in an airtight container at room temperature, where they’ll stay fresh for about a week. If you’re like me and want to keep that caramel-tasting brown butter goodness at its peak, make sure to keep them away from direct sunlight and humidity. For optimal freshness, consider adding a slice of bread to the container; it sounds quirky, but trust me—it helps maintain that delightful chewiness!
Storing Leftover vegan marshmallows Crispy Cookies (Costco Copycat)
To ensure your leftover vegan marshmallows crispy cookies remain as delicious as the day they were baked, opt for an airtight container—this is absolutely crucial! Whether you choose a glass jar or a plastic bin, just make sure it seals tightly. These cookies will keep beautifully at room temperature for about a week; however, I guarantee they won’t last that long if you share them with friends! To maintain their quality, don’t forget the bread slice trick I mentioned earlier; it works wonders in keeping those cookies soft and chewy while absorbing excess moisture. After a couple of days on the counter, they might develop a slightly firmer texture but still retain that charming flavor profile. When you’re ready to indulge again, simply pop them in the microwave for 10-15 seconds to revive that fresh-baked warmth right before serving.
Freezing vegan marshmallows Crispy Cookies for Later
Thinking ahead? Freezing these cookies is an excellent option for enjoying them later without compromising taste or texture! To freeze your vegan marshmallows crispy cookies, start by placing them in a single layer on a baking sheet lined with parchment paper. This allows each cookie to freeze individually without sticking together—a non-negotiable step if you want easy access later! Once they’re frozen solid (about 2-3 hours), transfer them into an airtight freezer bag or container labeled with the date. They’ll keep well in the freezer for up to three months. When you’re ready to enjoy one (or two!), simply take them out and let them thaw at room temperature or heat them directly from frozen in the microwave for about 20-30 seconds. The convenience factor here is wonderful—you can always have a little treat waiting for you whenever that cookie craving strikes!
