How to Make Lucky Charms Cookies

Preheat the Oven: Begin by preheating your oven to 350°F (175°C) and lining a large baking sheet with parchment paper to prevent sticking.
Cream Butter and Sugars: In a stand mixer, cream together 1/2 cup softened butter, 1/2 cup granulated sugar, and 1/4 cup brown sugar using a paddle attachment. Beat until light and fluffy, about 2-3 minutes.
Add Egg and Vanilla: Add in 1 large egg and 1 tsp vanilla extract. Mix for another 30 seconds until fully incorporated.
Mix Dry Ingredients: Gradually mix in 1 & 1/3 cups + 1 tbsp all-purpose flour, 2 teaspoons cornstarch, 1/2 tsp baking soda, 1/4 tsp baking powder, and 1/4 tsp salt. Stop mixing once the flour is just combined.
Fold in Marshmallows: Gently fold in 1 cup Lucky Charms marshmallows until evenly distributed throughout the dough.
Shape the Cookies: Using a small cookie scoop, place cookie dough balls on the prepared baking sheet. Roll each ball in extra marshmallows if desired, and make sure to leave at least 2 inches between each cookie as they will spread.
Bake: Bake cookies in the preheated oven for about 8-10 minutes until the edges are lightly golden and the centers appear soft.
Cool and Enjoy: Remove from the oven and let them rest on the baking sheet for 5-10 minutes. Transfer to a wire rack to cool completely, or enjoy warm straight from the oven.

Storing & Reheating

To keep your Lucky Charms Cookies fresh, store them at room temperature in an airtight container for up to 5 days. If you want to make them last longer, refrigerate them for up to 2 weeks. For longer storage, you can freeze them in a freezer-safe bag or container for up to 3 months. To reheat, pop them in the microwave for about 10-15 seconds or in a preheated oven at 350°F for 5 minutes. Keep in mind that the texture might change after freezing, but a quick warm-up should bring back some of that fresh-baked softness.

Chef’s Helpful Tips

Check Butter Temperature: Ensure your butter is softened but not melted; this helps create a perfect texture.
Don’t Overmix: Once you add the flour mixture, mix until just combined to prevent tough cookies.
Measuring Flour: Spoon and level the flour in measuring cups to avoid using too much, which can lead to dry cookies.
Experiment with Mix-ins: Feel free to add chocolate chips or nuts to the dough alongside the marshmallows for an extra flavor boost.
Chill the Dough: For thicker cookies, chill the dough for 30 minutes before baking.

Lucky Charms Cookies are a playful and nostalgic treat perfect for any occasion. With that delightful blend of buttery goodness and sweet, chewy marshmallows, these cookies provide not just a satisfying taste but fond memories wrapped in each delicious bite. Don’t hesitate to make these your go-to recipe for fun gatherings or simply for enjoying a cozy night at home. Let your creativity flow, play with flavors, and discover the joy of baking these delightful treats!
