What is Lucky Charms Sugar Cookies?

Lucky Charms Sugar Cookies are a colorful, chewy sugar cookie made with a rich buttery dough and studded with Lucky Charms marshmallows—yes, the ones from the cereal aisle. These cookies strike that perfect balance between chewy and soft, giving you a bakery-style texture without all the bakery drama. The marshmallows don’t just add flair—they create pockets of crispy sweetness that caramelize ever so slightly as they bake. The base is a classic sugar cookie, amped up with vanilla and a touch of salt to contrast the sugary cereal.

And the best part? You can press extra marshmallows on top post-bake to make them even more photogenic (read: Instagram-worthy). Though they’re especially popular around March, Lucky Charms Sugar Cookies are too good to limit to just one season. They’re whimsical enough for a birthday party, fun enough for a school snack, and just plain delicious enough for your average Tuesday. If you’re a fan of colorful desserts like our Green Cookies or Mint Chocolate Chip Cheesecake Dip, this one’s right up your alley.

Reasons to Try Lucky Charms Sugar Cookies

There are sugar cookies… and then there are Lucky Charms Sugar Cookies, which are basically the overachievers of the cookie jar. First, let’s talk visuals—those pastel-colored marshmallows instantly brighten up your day (and your kitchen). These cookies are a fun surprise in lunchboxes and always the first to vanish from party trays.

But beyond their charm, the real magic is in the texture. They’re thick, chewy, and have that perfectly tender center that melts in your mouth. You don’t need any fancy techniques or special equipment to make them either—just a bowl, a mixer, and a good appetite. Plus, the dough comes together in about ten minutes. Yup, just ten. Perfect for those “Oh no, the bake sale is tomorrow” moments. And if you’re trying to sneak some joy into a chaotic week (because life, am I right?), this recipe is pure feel-good baking. They’re also freezer-friendly, making them a great make-ahead treat. And if you’re planning a full-on St. Paddy’s Day dessert spread, pair them with Irish Cream Macarons or Irish Potato Candy for a seriously festive lineup.

Ingredients Needed to Make Lucky Charms Sugar Cookies

1/2 cup unsalted butter (room temperature)
1 cup sugar
1 egg
1 egg yolk
1 tsp vanilla extract
1 3/4 cup all-purpose flour (spooned and leveled)
1/2 tsp baking soda
1/2 tsp sea salt
1/2 cup Lucky Charms marshmallows (plus extra for pressing into the top)

Instructions to Make Lucky Charms Sugar Cookies – Step by Step

Step 1: Preheat and Prepare Your Baking Sheets

Let’s kick things off the smart way—by getting the oven preheated to 350°F. That way, it’s ready to go when your dough is. Grab three baking sheets and line them with parchment paper. Not only does it help with cleanup (can I get a hallelujah?), but it also keeps the bottoms of your cookies golden instead of burnt. If you’ve got kiddos helping out, let them “smooth the parchment”—they love feeling helpful.

Step 2: Cream the Butter and Sugar

In a medium mixing bowl, beat together 1/2 cup of room-temperature unsalted butter and 1 cup of sugar using an electric mixer on medium speed. Let this go for about 2 minutes, or until it’s light and fluffy like clouds in a cereal commercial. This step is key for that soft, bakery-style texture. Don’t rush it—even if a toddler is pulling on your leg.

Step 3: Add Egg, Yolk, and Vanilla

Next up, toss in 1 egg, 1 egg yolk (yes, both!), and 1 teaspoon of vanilla extract. Mix for another minute, just until everything’s combined and smooth. The egg yolk adds extra richness, giving you that magical melt-in-your-mouth feel. And the vanilla? That’s your cookie’s background singer, making everything taste just a little better.

Step 4: Dry Ingredients Go In

Add your dry ingredients—1 3/4 cups of all-purpose flour (be sure to spoon and level it), 1/2 teaspoon of baking soda, and 1/2 teaspoon of sea salt. Mix on low until just combined. The dough should look thick, but not dry. This is where you might be tempted to overmix, but don’t do it—gentle wins the cookie race.

Step 5: Fold in the Marshmallows

Now comes the fun part—fold in 1/2 cup of Lucky Charms marshmallows. Use a spatula to gently stir them in. Some might break a little, but that’s totally fine. Save a small handful to press into the tops later. This step is where the cookies really start to feel like a celebration in dough form.

Step 6: Scoop and Shape

Using a 3-tablespoon cookie scoop (or a big ol’ spoon), scoop the dough onto your prepared baking sheets. Give them some space—these cookies like to spread out and relax while baking. If you’re feeling extra fancy, chill the dough balls for 10 minutes to help them keep their shape better, but it’s optional.

Step 7: Bake to Perfection

Slide those trays into the oven and bake for 10 minutes. Rotate the pans halfway through baking for even browning—especially if your oven has a few hot spots (like that weird back corner). The edges should be just starting to turn golden while the centers still look slightly underdone. Trust the process; they’ll set as they cool.

Step 8: Cool and Add Extra Marshmallows

Once they’re out of the oven, let the cookies cool on the sheet for about 5 minutes. This helps them firm up enough to move without falling apart. Now’s your chance to press a few extra marshmallows into the tops for that picture-perfect finish. Then transfer to a wire rack to cool completely—if you can wait that long.

Step 9: Store or Freeze

Once fully cooled, pop them into an airtight container. They’ll stay soft and chewy for 3–5 days at room temp. Want to make them last longer? Freeze them for up to 3 months. Just make sure to separate layers with parchment to prevent sticking. It’s cookie insurance, and yes, that’s totally a thing.

What to Serve with Lucky Charms Sugar Cookies

These cookies pair beautifully with an ice-cold glass of milk (obviously), but they’re also fun with hot cocoa, a peppermint mocha, or even a scoop of vanilla ice cream for an extra treat. For a festive St. Patrick’s Day dessert spread, serve them alongside St. Patrick’s Day Rolo Pretzel Candy or Guinness Chocolate Cake for that grown-up twist. Hosting a party? Set them out with a variety of colorful sweets for a kid-approved dessert board.

Key Tips for Making Lucky Charms Sugar Cookies

Use room-temperature butter—it’s your secret weapon for smooth dough and fluffy cookies. Don’t overmix the dough once you add the dry ingredients; that can lead to tough cookies (and no one wants that). Save some marshmallows to press on top after baking—they won’t melt or brown weirdly like they can during the bake. Rotate your pans halfway through baking so every cookie gets equal love from the oven. If your marshmallows are sticky or clumping, toss them in a little flour before folding in. And most importantly, let them cool before moving. Warm cookies are fragile, and a broken cookie is a sad cookie.

Storage and Reheating Tips Lucky Charms Sugar Cookies

Store your Lucky Charms Sugar Cookies in an airtight container at room temp for up to 5 days—though good luck keeping them around that long. To keep them soft, toss a slice of sandwich bread in the container; the cookies steal the moisture (science magic). Want to freeze them? Place cookies in a single layer on a baking sheet until solid, then transfer to a zip-top bag or airtight container. When you’re ready to enjoy, let them thaw at room temp or zap them in the microwave for about 10 seconds for that fresh-baked warmth.

FAQs

Can I use regular Lucky Charms cereal, not just the marshmallows? You can, but we recommend using just the marshmallows for texture. The cereal pieces can soften and lose their crunch.
Where can I buy Lucky Charms marshmallows separately? Many online retailers carry them, or you can pick them out of the cereal box (a labor of love).
Do I need to chill the dough? Nope! But a short chill can help them bake up a little thicker. Totally optional.
Can I double the recipe? Absolutely. These cookies freeze well, so make a double batch and stash some for later.
Can I make this gluten-free? You can try swapping in a 1-to-1 gluten-free flour blend, though texture may vary slightly.
