How to make Lucky Charms cookies

This recipe makes 14-16 cookies!

1. Preheat the oven to 350°F (175°C) and line a cookie sheet with parchment paper.
2. In a large bowl, cream butter, brown sugar, and granulated sugar together until light and fluffy.
3. Mix in the egg and vanilla until smooth.
4. Whisk together your dry ingredients: flour, baking soda, and salt in a separate bowl, then gradually add to the wet ingredients.
5. Fold in Lucky Charms marshmallows and white chocolate chips (if using) gently.
6. Scoop dough onto the baking sheet, spacing cookies about 2 inches apart. 
7. Bake for 10-12 minutes, until edges are golden but centers remain soft.
8. Cool for 5 minutes on the pan, then transfer to a wire cooling rack to cool completely.
9. Serve with a glass of cold milk and enjoy!

I like making these cookies in my stand mixer, but you can also use an electric hand mixer too! 

Tips for the Best Lucky Charms Cookies

• Scooping cookies: I used an ice cream scoop and filled it about halfway with every scoop. You can use a cookie scoop
• Use only the marshmallows: Instead of using the full cereal, pick out just the colorful marshmallows for the best texture. The crunchy cereal pieces can become too chewy when baked. You can also just buy a bag of the marshmallows if you don't feel like digging through the cereal and picking out the marshmallows!
• Don’t overbake: These cookies will continue to firm up as they cool, so it’s best to remove them from the oven when they still look slightly underbaked in the center.
• For extra marshmallow magic: Press a few extra marshmallows onto the tops of the cookie dough balls before baking them.

Storing Leftover Cookies

To keep your cookies fresh and delicious, you can do one of two things. Store them in an airtight container at room temperature for up to 5 days or if you want to keep them longer, freeze them for up to 2 months. Just place them in a freezer-safe bag and thaw them at room temperature before enjoying.

Substitutions and variations

Salted vs. unsalted butter. ​

Add more mix-ins. Try adding white chocolate chips, semi-sweet chocolate chips, or rainbow sprinkles for extra fun.

Make them gluten-free. Swap the all-purpose flour for a 1:1 gluten-free flour blend.

Use a sugar cookie base. If you love classic sugar cookies, use your favorite sugar store-bought cookie dough recipe and mix in the Lucky Charms marshmallows.

Lucky Charms frosting. ​You can use the Lucky Charms cereal milk to make a frosting to frost the top of the cookies. 

FAQs

Can I make these cookies ahead of time?

Yes! You can prepare the dough in advance and store it in the fridge for up to 24 hours before baking. You can also freeze the cookie dough balls and bake them straight from the freezer—just add an extra 1-2 minutes to the baking time.

Why are my Lucky Charms marshmallows melting?

Some melting is normal, but if they’re completely disappearing, try mixing them in gently and avoiding overmixing. Also, pressing extra marshmallows onto the tops of the cookies right after baking helps them stay visible.

Can I double this recipe?

Absolutely! If you’re making cookies for a large crowd or a party, simply double the ingredients and bake in batches. Just be sure you have enough extra Lucky Charms marshmallows!
