Lucky Charms Cookies, Made Easy

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper to prepare for the cookies.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, salt, baking soda, and baking powder. Set this mixture aside.
Step 3: Cream Butter and Sugar
In a large mixing bowl, use an electric mixer to cream together the unsalted butter and granulated sugar until the mixture is light and fluffy. This should take about 2-3 minutes.
Step 4: Add the Eggs and Vanilla
Beat in the large eggs and extra yolk, one at a time, mixing well after each addition. Then, add the vanilla extract and mix until combined.
Step 5: Incorporate Dry Ingredients
Gradually add the dry ingredients to the wet mixture. Mix until just combined; be careful not to overmix.
Step 6: Add the Special Ingredients
Fold in the Marshmallow Fluff (if using), crushed Lucky Charms cereal, and marshmallow pieces until evenly distributed. If desired, add a few drops of green food coloring for a fun touch!
Step 7: Scoop and Bake
Using a cookie scoop or spoon, drop rounded tablespoons of dough onto the prepared baking sheet, leaving enough space between each cookie to allow for spreading. Top each cookie with a few extra marshmallow pieces.
Step 8: Bake
Bake in the preheated oven for 10-12 minutes, or until the edges are golden and the centers are just set. The cookies will continue to cook slightly as they cool.
Step 9: Cool and Enjoy
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. Enjoy your Lucky Charms Cookies with a glass of milk or your favorite beverage!
Allergy-Friendly Substitutes

- Gluten-Free: Substitute all-purpose flour with a 1:1 gluten-free flour blend.
- Dairy-Free: Use dairy-free butter and shortening alternatives to keep it dairy-free.
- Egg-Free: Replace eggs with flax eggs (1 tablespoon flaxseed meal + 2.5 tablespoons water = 1 egg).
- Low Sugar: Substitute granulated sugar with coconut sugar or a sugar alternative.
Errors to Dodge
- Overmixing the Dough: This can lead to tough cookies. Mix until just combined.
- Skipping the Chilling: If your dough is too warm, the cookies may spread too much. Chill for 30 minutes if necessary.
- Incorrect Oven Temperature: Make sure your oven is correctly calibrated. An oven thermometer can help.
- Not Allowing to Cool: Let the cookies cool on the baking sheet to finish setting up before transferring to a wire rack.
Make-Ahead & Storage
You can prepare the dough in advance and refrigerate it for up to 3 days. Just scoop the dough onto a baking sheet, cover it with plastic wrap, and store it in the fridge until you’re ready to bake.
To store baked cookies, place them in an airtight container at room temperature for up to a week. If you want to keep them longer, you can freeze them for up to three months. Just make sure to separate layers with parchment paper to prevent sticking!
Ask & Learn
Can I make these cookies without the Marshmallow Fluff?
Yes, while it adds extra sweetness and a chewy texture, you can simply omit it if you prefer a less sweet cookie.
What can I do if my cookies are too flat?
Flat cookies can be a result of too much butter or not enough flour. Make sure to measure your ingredients accurately, and consider chilling the dough before baking.
Can I add chocolate chips to the recipe?
Absolutely! Chocolate chips would make a great addition and pair well with the Lucky Charms flavors.
How do I know when my cookies are done baking?
The edges should be lightly golden, and the centers will look slightly underbaked. They will continue to set as they cool.
