Ingredients for this Lucky Charms Cookies Recipe

Scroll down to the recipe card at the bottom of the page for the detailed ingredient measurements. 

• 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 this Lucky Charms Cookies Recipe

Make sure to scroll down to the recipe card at the end of this post for the full step-by-step instructions! 

1. Start by preheating the oven then line a large nonstick cookie sheet with parchment paper and set aside.
2. 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.
3. 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.
4. 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.
5. 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!

Recipe Tips

• 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.
• Once you have the right amount of flour, sift the flour into the mixing bowl using a sieve to break up any clumps. If there are no clumps in your flour no need to worry about this step.
