    🥘Lucky Charms Cookies Ingredients

    In addition to your typical cookie-baking ingredients, you'll need to grab a box or two of cereal. If you want to make your buttercream green for St. Patrick's day, go ahead and pick up some green food coloring as well.

    Lucky Charms cookies ingredients measured out and ready to make the cookie dough, bake the cookies, and then frost them before serving.

    Lucky Charms Cookies

    • Butter - 1 cup (2 sticks / 16 tablespoons) of room-temperature butter
    • Sugar - ¾ cup of white granulated sugar.
    • Light Brown Sugar - ¾ cup of packed light brown sugar.
    • Vanilla - 1 teaspoon of pure vanilla extract.
    • Baking Soda - 1 teaspoon of baking soda.
    • Salt - 1 teaspoon of salt.
    • Eggs - 2 large, room-temperature eggs.
    • Flour - 3 cups of all-purpose flour, spooned and leveled.
    • Marshmallows - 2 cups of marshmallows from the cereal. You can sometimes find these sold in a package by themselves, but picking the marshmallows out from the cereal is a fun activity for the kids, too!

    Cereal Milk Buttercream Frosting

    • Milk - 1 cup of whole milk.
    • Lucky Charms™ Cereal - 1 cup of Lucky Charms™ cereal. I used the cereal that was leftover from picking out the marshmallows, but you could definitely use some with the marshmallows still mixed in as well (but it might alter the color of your frosting).
    • Butter - 1 cup (16 tablespoons / 2 sticks) of room-temperature butter.
    • Confectioners' Sugar - 5 cups of confectioners' sugar.

    Topping

    • Cereal - 1½ cups of marshmallow cereal to load on top of the frosting for a fun and tasty topping!

    🔪 How To Make Lucky Charms Cookies

    There are two easy steps to these cookies- making the cookies and the frosting. Then you assemble them and have fun! These cookies are perfect for making with kids!

    You will need mixing bowls, an electric mixer, a baking sheet, a silicone spatula, a cooling wrack, and your measuring utensils. The recipe will make roughly 40 cookies to bring to any St. Patrick's day festivities!

    1. Soak the cereal. In a medium-sized bowl, mix together 1 cup of cereal and 1 cup of milk for the frosting. Set it aside while you prepare the cookies.
    2. Preheat. Preheat your oven to 375°F (190°C) and line your baking sheet with some parchment paper (or you can use a silicone baking mat).
    3. Cream the butter. Use your stand mixer or a hand mixer to cream together 1 cup of room-temperature butter, ¾ cups of both sugar and brown sugar, and 1 teaspoon each of vanilla extract, baking soda, and salt until creamy and smooth.
    4. Add eggs. Add the 2 large eggs, one at a time, mixing well between each addition, stopping to scrape down the bowl as necessary.
    5. Add flour. Slowly add 3 cups of flour, mixing until just combined, and then stir in 2 cups of cereal marshmallows.

    Portion & Bake the Cookies

    1. Scoop. Drop the dough by rounded tablespoons onto the prepared baking sheet using a measuring spoon or cookie scoop.
    2. Bake. in the preheated oven at 375°F (190°C) for 9-11 minutes or until they are a light golden color.
    3. Cool. Remove the cookies from the oven and allow them to cool slightly before transferring them to a cooling rack. Let the cookies cool entirely before continuing.

    1. Strain. Place a strainer over a bowl and strain out the soggy cereal to get your cereal milk. Set the bowl aside.
    2. Cream the butter. Use your stand mixer to cream 1 cup of butter on medium speed until light and creamy. Then, slowly add in 5 cups of confectioners' sugar until fully incorporated.
    3. Add milk. Pour the cereal milk into the frosting one tablespoon at a time, mixing well in between each addition until you reach your desired consistency (I used 6 tablespoons).
    4. Frost the cookies. Spread the frosting onto the cooled cookies and top with 1½ cups of cereal.

    Serve these cookies alongside some other fun Shamrock recipes or even a treat after eating some traditional Irish dishes! They are going to be a hit with both kids and adults! Enjoy!

    💭 Angela's Tips & Recipe Notes

    • One standard-sized cereal box (10.5 ounces) contains about 2 cups of marshmallows. You can have everything you need for this recipe with one larger-sized box (family size is 18.6 ounces) or with one standard-sized box if you don't mind the topping not including marshmallows. 
    • If desired, you can chill your cookie dough for an hour before baking. This will reduce how much they spread. 
    • You can add some of the crushed cereal into the dough for texture, crunch, and thickness!
    • You can make these cookies as directed but omit the frosting for a simple yet tasty variation! You'll still have a tender cookie loaded with cereal marshmallows!

    🥡 Storing

    Store your cookies in a sealed container in the fridge for 5-7 days. They can be left at room temperature, but only for 2-3 days due to the buttercream frosting.

    ❓ FAQ

    Can I Use Different Marshmallows For These Cookies?

    Any dehydrated marshmallows can be used in cookies. However, standard and mini marshmallows will melt at or above 104°F (40°C).

    Is It Better To Bake Cookies With Shortening Or Butter?

    Shortening won't spread as much in the oven as butter. However, butter adds a super-rich flavor and yields some crisp edges. It is all up to your personal preference, but I like to bake my cookies using butter!

    Does Buttercream Frosting Need To Be Refrigerated?

    Buttercream frosting can remain at room temperature for 2-3 days. However, it lasts longer when stored in the refrigerator (up to 1 week).
