Ingredients for this Lucky Charms Cookies Recipe

These cookies use simple pantry ingredients combined with Lucky Charms marshmallow bits to create soft, chewy cereal cookies.
- Butter: Be sure to use unsalted butter so that it doesn’t alter the flavor. You will want the butter to be room temperature, so try to pull it out of the fridge an hour before you prepare the recipe.
- Granulated Sugar: It can’t be a sugar cookie without sugar!
- Brown Sugar: You may not expect it, but brown sugar is great in sugar cookies because it adds chewiness.
- Large Egg: is necessary to help give the cookies firmness and chewiness.
- Vanilla Extract: is responsible for the main flavor that you taste in delicious sugar cookies.
- All Purpose Flour: combines with the egg and other ingredients to create the cookie structure.
- Cornstarch: A little goes a long way to help keep the texture of these cookies ultra tender.
- Baking Soda and Baking Powder: give the cookies rise and air as their baking to give it the perfect texture.
- Salt: A key ingredient that enhances all of the other flavors.
- Lucky Charms Marshmallow Pieces: for rolling the cookies. You can buy an individual bag of just marshmallows in stores or online.

How to Make Lucky Charms Cookies
- Start by preheating the oven then line a large nonstick cookie sheet with parchment paper and set aside.
- In a bowl of a stand mixer, cream the softened butter, granulated sugar and brown sugar together using a paddle attachment until light in color and fluffy. Add in the egg and the vanilla and mix again for 30 seconds or until fully incorporated.
- Add in the dry ingredients: flour, baking soda, cornstarch, baking powder, and salt and mix just until the flour disappears. Using a small cookie scoop, scoop out equally sized cookie dough balls. Scrape the sides of the bowl with a rubber spatula to get every last piece.


- Roll them in the tasty marshmallow bits and place them on the prepared baking sheet. Make sure to leave 2 inches between each cookie because they will spread. Add extra marshmallows to the top of the cookies if you have more space.
- Bake the cookies, then pull them out and let them rest on the cookie sheet before transferring to a cooling wire rack. Serve with a tall glass of cold milk and enjoy your Lucky Charms cookies!


Instead of using a measuring cup, use a kitchen scale to weigh your ingredients. Scooping flour with a measuring cup can be difficult and inaccurate and can end up making your cookies taste different.

are the marshmallows different than ones in the cereal?
No, they are the same. I just buy them separately around St Patrick’s day because it’s easier than fishing them out of a cereal box.
Hi! This recipe looks very good. I am trying to prep these cookies for later, can I refrigerate my dough?
You can, but just allow them to get back to room temperature before baking.
