These big, soft and chewy, bakery style Lucky Charms cookies are loaded with Lucky Charms marshmallows, topped with whipped pink vanilla buttercream and topped with even more marshmallows and cereal.
These cookies are perfect for St. Patrick's Day but I make them throughout the year because my kids LOVE them. My kids also really love when I put the remaining box of cereal without marshmallows back into the pantry.....kidding. But really, these cookies are so, so good and fun to make.
Why You Will Love This Recipe

All purpose flour
Fine sea salt
Milk, or cream
Pink gel food color, just a drop or two to color the frosting
Lucky Charms cereal
Before beginning the recipe, preheat the oven to 350F, and line two large cookie sheets with parchment paper.
- Whisk together the dry ingredients, flour, baking soda and salt in a medium bowl.
- Beat together the butter, granulated sugar and brown sugar with a hand mixer or with an electric mixer for 3-5 minutes, until light and fluffy.
- Beat in the vanilla and eggs, one at a time.
- Beat in the dry ingredients, until just combined.
- Fold in the marshmallows. Fold gently if you wish to keep some of the marshmallows from breaking, if you want them whole.
- Scoop the dough into cookie portions with a ¼ cup (2oz) ice cream scoop.
- Form the dough balls into disc shapes, about ½" thick. Place 6 on each cookie sheet, at least 3" part.
- Bake for 10-11 minutes until the cookies are starting to turn golden around the edges, and until the centers of the cookies look just set and no longer shiny.
- While the cookies cool, make the frosting. Beat together the butter, confectioner's sugar, milk, vanilla, and salt until thoroughly combined.
- Beat in the gel food color. Beat the frosting for an additional 3-5 minutes until light and fluffy.
- Optionally, place the frosting into a piping bag fitted with a large round tip and pipe a big dollop of icing in the center of each cookie. Alternatively you can use a spatula to spread the frosting onto the cookies.
- Use a spatula to spread the frosting over the tops of the cookies. Top the cookies with more cereal before serving.
- Don't over bake. Bake the cookies until they have spread out and puffed a bit, and the top looks just set, or no longer shiny, about 10 minutes.
- Whip the frosting. Whipping the frosting after everything has been beaten together ensures a light, airy, and fluffy frosting.
- If the frosting is too thick, add an additional tablespoon or two of milk.
Storage and Freezing
These cookies are best eaten the the say they are made, as the cereal topping tends to get soft after a day. If you making these in advance, frost and sprinkle with cereal before serving.
Unfrosted cookies can be stored in an airtight container for up to three days. Frosted cookies without cereal topping can be stored in an airtight container in the refrigerator for up to 5 days. They are best served at room temperature.
Unfrosted cookies can be stored in airtight container and frozen for up to 3 months. Frosted cookies without cereal topping can be frozen in a single layer to set the frosting, then stored in an airtight container for up to 3 months. Defrost in the refrigerator and serve room temperature.
Be sure to form the cookies into disc shapes before baking. The disc should be about ½" thick. For the best results, bring the dough to room temperature before baking.
This recipe makes 12 large bakery style cookies, but you can make them smaller to make up to 24 cookies. Reduce the baking time to maintain the cookie's soft texture.
