Ingredients
Here are some useful notes on the ingredients needed to make this Lucky Charm cookie recipe.
- Lucky Charms cereal: Lucky Charms add color sweet gooey bites and a little crunch to these cookies. They’re perfect for St. Patrick’s Day just like my matcha cookies!
- Flour: I use all-purpose flour. Avoid using too much flour. To measure flour, spoon it into your measuring cup and level it off with the back of a knife. To measure your flour the most accurately, use a kitchen scale.
- Butter: Use unsalted room temperature butter.
- Sugar: Use both granulated and light brown sugar.
- 1 Egg: Use a large, room temperature egg. Take the egg out of the fridge 1 hour before making these cookies
See recipe card below for a full list of ingredients and measurements.
Substitutions and Variations
- Swap in salted butter in place of the unsalted butter. You don’t need to add salt if you use salted butter.
- Use dark brown sugar instead of light brown sugar.

Expert Tips
Bake one tray of cookies at a time. Baking one tray of cookies at a time allows for the best and most even heat circulation.
Place the baking sheet on the middle rack. Baking the cookies in the center of the oven puts the cookies at the best distance from the heat source.
Don’t overbake the cookies. Take them out as soon as the edges start to brown.
Stick a couple extra pieces of Lucky Charms (cereal or marshmallows) on top of the cookie dough balls right before baking if you like!
Recipe FAQs
Yes! You can leave out the cereal part. Just add extra Lucky Charms marshmallows in place of the cereal.
Take a tablespoon or tablespoon measuring spoon, scoop some dough and just drop it onto your baking sheet. You don’t need to smoosh it down or anything. Here’s a good video that shows how to drop by rounded tablespoon.
Store these cookies with Lucky Charm marshmallows in an airtight container. Store at room temperature for 3 to 4 days. Freeze leftover cookies or unbaked cookie dough balls in a freezer storage bag for up to 2 months.

I think the addition of sour cream to the dough is genius. The texture of the cookie is next level! so soft and chewy. I ate so many before I even realized what I was doing. also the marshmellows are delicious and so cute and fun. I’m totally going to make these again. I also think it would be great to use this cookie base for other mix ins.

Thank you so much for making these cookies and for your feedback, Olivia! So happy you enjoyed them! Yes isn’t the texture so good?! I got that sour cream idea from my great grandmother’s sour cream cookie recipe and I’ve used it for a base for lemon sour cream cookies, chocolate chip sour cream cookies, blood orange cookies, and key lime cookies haha so you’re totally right-it’s the best cookie base for so many mix ins and flavors! Hope you’ll try some of the other sour cream cookie recipes! Have a fantastic weekend 🙂
