Delicious Lucky Charms Cookies with Marshmallow Buttercream.

When it comes to celebrating any holiday, or even just making a regular day special, what’s a better way to do so than with freshly baked cookies?

Now, I know what you might be thinking – Lucky Charms aren’t traditionally Irish. And yes, some might argue that Lucky the Leprechaun isn’t authentically Irish either. But let’s face it, these cookies are incredibly delicious and undeniably festive! I’m more than happy to bake them for St. Patrick’s Day or any other occasion, and I bet you will be too!

The inspiration for this delightful cookie actually came from Crumbl. They offer a Lucky Charms cookie around St. Patrick’s Day, which sparked the idea to create my own version. But I believe this recipe is even better because it incorporates the iconic Lucky Charms marshmallows directly into the cookie dough, adding an extra burst of flavor and fun.

These cookies disappeared incredibly quickly in my household. They are so good that they’re bound to become a beloved holiday staple!

Ingredients needed to make Lucky Charms Cookies.

Ingredients for the Best Lucky Charms Cookies

Here’s a breakdown of the ingredients you’ll need to create these delightful Lucky Charms Cookies:

  • Butter: You’ll need butter for both the cookies and the frosting. I recommend using unsalted butter to have better control over the overall saltiness of the recipe.
  • Sugar: Granulated sugar is used for the cookies to provide sweetness and structure, while powdered sugar is essential for achieving the smooth and creamy texture of the marshmallow buttercream frosting.
  • Eggs: Large eggs are the standard size for baking and contribute to the cookie’s moisture and binding. Using room-temperature eggs helps them emulsify more easily with the other ingredients, resulting in a smoother dough.
  • Vanilla Extract: A touch of vanilla extract enhances the overall flavor profile of both the cookies and the frosting. Opt for pure vanilla extract for the best and most authentic vanilla flavor.
  • Baking Powder and Salt: Baking powder acts as a leavening agent, helping the cookies rise and achieve a light and airy texture. Salt not only balances the sweetness but also enhances the other flavors in the recipe.
  • All-Purpose Flour: All-purpose flour is the foundation of these cookies, providing the necessary structure and chewiness.
  • White Chocolate Chips: For those who like that extra dose of sweetness.
  • Lucky Charms Marshmallows: These are the star of the show! You can either pick the marshmallows out of a box of Lucky Charms cereal or purchase bags of just the marshmallows for convenience.
  • Marshmallow Creme: This provides the base for the incredibly creamy marshmallow buttercream frosting. Marshmallow fluff can also be used as a substitute if marshmallow creme is unavailable.
  • Milk: A small amount of milk may be needed to adjust the consistency of the frosting. Add it gradually until the frosting reaches a smooth and spreadable texture.

How to Make Lucky Charms Cookies: A Step-by-Step Guide

Follow these simple steps to bake the most delicious Lucky Charms Cookies:

STEP 1: Cream together the butter and sugar using a mixer or by hand. The mixture should become light, fluffy, and pale in color.

STEP 2: Incorporate the eggs one at a time, followed by the vanilla extract. Make sure each ingredient is fully mixed in before adding the next.

STEP 3: In a separate bowl, whisk together the baking powder, salt, and flour. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix the dough, as this can result in tough cookies.

STEP 4: Gently fold in the white chocolate chips and Lucky Charms marshmallows until evenly distributed throughout the dough. It’s best to mix in the marshmallows by hand to prevent them from breaking apart too much.

STEP 5: Scoop the cookie dough into large balls, approximately 1/3 cup each. Flatten each ball slightly into a disc shape and arrange them on two baking sheets lined with parchment paper, leaving enough space between each cookie for spreading. Aim for about 6 cookies per sheet.

STEP 6: Bake the cookies in a preheated oven until the bottoms are lightly golden brown and the tops are set. Keep an eye on them to prevent overbaking.

STEP 7: While the cookies are cooling, prepare the marshmallow buttercream frosting. In a bowl, beat together the butter and marshmallow creme until smooth and creamy.

STEP 8: Add the salt and vanilla extract to the frosting mixture and mix well to combine.

STEP 9: Gradually add the powdered sugar, mixing until a smooth and fluffy frosting forms. If the frosting is too thick, add a small amount of milk until you reach the desired consistency.

STEP 10: For an extra touch of festivity, add a few drops of food coloring to the frosting and mix until evenly colored. This step is completely optional.

STEP 11: Once the cookies have cooled completely, generously frost each cookie with the marshmallow buttercream. Top each cookie with a sprinkle of Lucky Charms cereal for a final touch of magic.

Tips and Tricks for Perfect Lucky Charms Cookies

Here are some helpful tips and tricks to ensure your Lucky Charms Cookies turn out perfectly every time:

  • When adding the Lucky Charms marshmallows, mix them in by hand using a spatula instead of a mixer. This will help prevent the marshmallows from breaking apart and maintain their shape.
  • If you’re not planning on serving the cookies immediately, avoid adding the Lucky Charms cereal topping until right before serving. The cereal can become soft and soggy if stored for an extended period of time.
  • These cookies can be stored in an airtight container at room temperature or in the refrigerator for longer shelf life. I personally enjoy them both ways – at room temperature for a softer texture or chilled for a firmer bite.
