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.

My kids loved these. They kept saying how soft they were. Had a few myself and loved them. Lucky Charms are a nice fun touch.

Yay! So happy you and your kids enjoyed these! I love how soft they are too and Lucky Charms are always fun. Thanks for making them!

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.
Natalie
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 🙂
