Ingredients You’ll Need

1 cup (2 sticks) unsalted butter, softened: This provides the rich, creamy base for your cookies. Ensure it’s at room temperature for easy creaming.

1 ½ teaspoons vanilla extract: Enhances the flavor profile; always opt for pure vanilla extract for the best results.
2 ¾ cups all-purpose flour: The main structure of your cookies. Scoop and level for accurate measurement.
3 tablespoons finely crushed Lucky Charms oat cereal pieces: These pieces add texture and that signature cereal flavor.
2 tablespoons finely crushed graham crackers: Contributes a warm, toasted flavor that complements the marshmallows.
2 tablespoons nonfat milk powder (optional): Enhances the flavor and texture; you can omit it but it adds lovely creaminess.
1 tablespoon cornstarch: Keeps cookies soft and chewy. It’s essential for achieving the right texture.
½ teaspoon baking powder: Provides leavening, making your cookies light and fluffy.
¼ teaspoon baking soda: Helps with browning and rising.

Marshmallow Frosting Ingredients

¾ cup (1 ½ sticks) unsalted butter, room temperature: Key for creating a creamy texture for the frosting.
1 ¾ cups confectioners’ sugar: Sweetens the frosting and gives it structure. Sift before measuring for a light texture.
1 cup marshmallow fluff: Adds a delightful sweetness and lightness; a must for that marshmallow flavor.
2 tablespoons heavy cream: Adjusts the consistency for easy spreading.
1 teaspoon vanilla extract: Provides that rich flavor that ties the frosting together.
Pinch salt: Just a touch to balance the sweetness.

How to Make Lucky Charms Cookies

Cream the Butter and Sugars: In a mixing bowl with a paddle attachment, combine 1 cup (2 sticks) softened unsalted butter, 1 cup granulated sugar, and 2 tablespoons light brown sugar. Beat on medium speed until light and fluffy, about 2-3 minutes. This aeration is crucial for a nice texture.
Add the Eggs and Vanilla: Mix in 2 large eggs one at a time, ensuring each is fully incorporated before adding the next. Then, blend in 1 ½ teaspoons vanilla extract.
Combine Dry Ingredients: In a separate large bowl, whisk together 2 ¾ cups all-purpose flour, 3 tablespoons finely crushed Lucky Charms oat cereal pieces, 2 tablespoons finely crushed graham crackers, 2 tablespoons nonfat milk powder (if using), 1 tablespoon cornstarch, ½ teaspoon baking powder, ¼ teaspoon baking soda, and ½ teaspoon salt. This mixture ensures uniform distribution of dry ingredients.
Mix Wet and Dry: Gently add the dry ingredients to the wet ingredients until just combined. Be careful not to over-mix; you want a tender cookie. Fold in ¾ cup white chocolate chips, ensuring even distribution.
Chill the Dough: Scoop about ⅓ cup of dough at a time, roll into tall balls, and place them on a parchment paper-lined baking sheet. Gently press the tops down slightly. Chill the dough in the refrigerator for about 30 minutes to help the cookies maintain their shape during baking.
Bake: Preheat your oven to 350 degrees Fahrenheit. Once chilled, bake cookies for 12-16 minutes, until the edges are just set and the centers look slightly underdone. This gives you that soft, chewy texture.
Cool: Let cookies cool on the baking sheet for a few minutes before transferring them to metal racks to cool completely.
Frost and Decorate: Once cooled, frost cookies with marshmallow frosting. For a professional look, use a pastry bag fitted with a Wilton 2A tip. Gently press Lucky Charms marshmallows into the frosting and sprinkle with edible gold glitter if desired.
Prepare the Marshmallow Frosting: In a stand mixer or bowl with a hand mixer, beat ¾ cup (1 ½ sticks) softened unsalted butter until creamy, about 2-3 minutes. With the mixer on low, gradually blend in 1 ¾ cups confectioners’ sugar, ½ cup at a time, until well-combined. Beat in 1 cup marshmallow fluff, 1 teaspoon vanilla extract, and a pinch of salt. Add 2 tablespoons heavy cream and mix until smooth.

Storing & Reheating

Store Lucky Charms Cookies in an airtight container at room temperature for up to 5 days. If you want them to last longer, you can refrigerate them for about a week. For freezing, place cookies in a freezer-safe container, separating layers with parchment paper, and freeze for up to 3 months. To enjoy them warm, simply reheat in the oven at 350 degrees Fahrenheit for about 5-7 minutes. The texture might soften slightly upon thawing, but they’ll still taste fantastic!

How can I make these cookies dairy-free?

To accommodate a dairy-free diet, use dairy-free butter and ensure that your white chocolate chips are dairy-free. You can also replace the heavy cream in the frosting with a non-dairy alternative.
