Lucky Charms Cookies
There’s something about Lucky Charms that instantly feels nostalgic. The colors. The marshmallows. The cereal you picked through as a kid.
These Lucky Charms cookies take that playful cereal moment and turn it into a soft, gooey, bakery-style cookie. They’re made with brown butter for depth, packed with marshmallows, and baked just until the centers are slightly underdone so they stay soft.
They feel festive enough for St. Patrick’s Day but actually they’re fun all year.
If you’re looking for a unique cookie recipe that stands out from classic chocolate chip, this is the one.

Tips for Perfect Lucky Charms Cookies
Do not overbake.
They should look slightly soft in the middle when removed.
Press marshmallows on top before baking.
If you mix them fully in, many will melt invisibly.
Use parchment paper.
Marshmallows can stick as they melt.
Let them cool properly.
They firm up as they sit.
Storage
Store in an airtight container at room temperature for up to 3 days.
For longer storage, freeze baked cookies for up to 2 months. Let thaw at room temperature.
You can also freeze the dough balls and bake straight from frozen. Just add 1–2 extra minutes.

Frequently Asked Questions
Can I skip browning the butter?
Yes, but the flavor will be more basic sweet cookie rather than rich and slightly nutty.
Do the marshmallows melt completely?
Some melt into the cookie, creating gooey pockets. The ones pressed on top stay visible.
Can I make smaller cookies?
Yes. Use 2 tablespoons of dough and bake 8–9 minutes.
There’s something about a cookie that feels playful but still tastes grown-up. The brown butter keeps these grounded. The marshmallows keep them fun. (linked here)
