Key Ingredients
- Butter – use unsalted butter softened at room temperature.
- Sugar – regular white granulated sugar.
- Brown Sugar – I like to use light brown sugar for this recipe but you can use dark brown sugar if you prefer more of a molasses flavor.
- Eggs – any kind of large eggs will work. It’s best if they are at room temperature so that they don’t “shock” the butter when you add them.
- Baking Powder and Baking Soda – the combination of these two ingredients helps the cookies to rise and stay nice and soft.
- Flour – all-purpose flour works great for these cookies.
- Chocolate Chips – this Lucky Charm cookie dough calls for white chocolate chips for both the flavor and the color. If you find that these cookies are a bit too sweet, you can always use slightly less white chocolate chips, substitute semi-sweet chocolate chips, or even skip them altogether.
- Lucky Charms Marshmallows – in order to get the most colorful cookies, I recommend using only the marshmallows from Lucky Charms cereal. The Lucky Charms ingredients list calls for 2 cups Lucky Charms marshmallows, but feel free to add slightly less or reserve some to add to the tops while they are still warm.

How to Make Lucky Charm Cookies
- Separate the marshmallows from the cereal. Separate marshmallows from the Lucky Charms cereal until you have 2 cups of marshmallows. Set aside.
- Cream the butter and sugar. In the bowl of a stand mixer, cream together the butter, sugar, and brown sugar using the paddle attachment for about 3-5 minutes, or until light and fluffy.
- Mix the rest of the Lucky Charm cookie dough. Slowly add the eggs, vanilla and salt and mix on low to combine. In a separate large bowl, whisk together the flour, baking powder, and baking soda. Mix until combined, then add the dry ingredients to the butter and sugar mixture. Mix on low speed until mixed, scraping the bottom and the sides of the bowl as necessary.
- Add the chocolate chips and marshmallows. Add the white chocolate chips and Lucky Charm Marshmallows, mixing on low just until combined. Do not overmix!
- Scoop the cookies. Using a small ice cream scoop, or a spoon, scoop 2″ balls and place onto an ungreased or parchment lined baking sheet about 2″ apart.
- Bake. Bake in a preheated oven for 9-11 minutes, or until lightly golden brown and set around the edges. Top with extra marshmallows as soon as they come out of the oven, if desired.
- Cool. Let the cookies cool on the baking sheet for 5 minutes before transferring the cookies to a cooling rack to cool completely.
- Enjoy!
Recipe Variations
If you are looking for more lucky cookies for birthday parties, St Patricks Day, or just for fun, here are a few ideas:
- Lucky Charms Chocolate Chip Cookies: Try using regular chocolate chips instead of white chocolate. The combination of gooey chocolate and crispy cereal creates a textural contrast that is sure to delight.
- Lucky Charms Oatmeal Cookies: Give your oatmeal cookies a playful twist by adding Lucky Charms cereal. The oats provide a hearty base, while the cereal adds a hint of magic and a satisfying crunch.
- Lucky Charms Peanut Butter Cookies: Combine the rich and nutty flavor of peanut butter with the whimsical crunch of Lucky Charms cereal. These cookies are a delicious blend of sweet and savory, perfect for any peanut butter lover.
- Lucky Charms Sugar Cookies: Transform traditional sugar cookies into a colorful treat. The cookies retain their classic buttery flavor, but the cereal adds a playful and eye-catching element.
- Lucky Charms Gluten-Free Cookies: For those with gluten sensitivities, fear not! You can still enjoy the whimsy of Lucky Charms cookies with a gluten-free twist. Simply substitute gluten-free flour and oats in your favorite recipe.

Frequently Asked Questions
This recipe calls for just the marshmallows, meaning you will need to sort through the cereal. You can add the cereal as well, but they won’t be nearly as colorful.
If you bake these cookies in a preheated 350 degree oven, they should take about 10 minutes to bake, give or take a minute or two. You want to bake just until the edges are set and very lightly golden brown.
Because you are adding colorful Lucky Charms marshmallows to the cookie dough, I don’t recommend chilling the dough for more than 20 minutes if at all. If they sit in the fridge for too long, the marshmallows actually start to take on some of the moisture and break down a bit. If you really want to chill the dough, or you want to make the dough the night before, don’t add the marshmallows. Instead, press them gently into the tops just before baking.
Storing Instructions
- Room Temperature: I recommend only storing these cookies at room temperature so that the colorful marshmallows don’t begin to break down. The best way to keep the marshmallows fresh after baking is to store them at room temperature lightly covered with foil. You can also store them in an airtight container or freezer bag, but know that the marshmallows will get a bit gooey.
