Marshmallow stuffed Lucky Charms Cookies are everything magical and super delicious! Filled with cereal bits, crunchy marshmallows, and baked to perfection!
These cookies are fun to make and fun to eat!
Who doesn’t love Lucky Charms- okay I know a few don’t but this year I really wanted to have some as my birthday breakfast? Weird I know, but I made it happen.
After a few bowls I decided I wanted to take my favorite childhood cereal and turn it into a tasty cookie- because why not?!
Plus, I love cookies!
Other cookies I love:
Soft and chewy- perfectly delicious!
A little while ago I made S’mores Cookies and I thought why not do the same thing with these? After all the Lucky Charms marshmallows are my favorite part of the cereal so why not add more marshmallow.
How to make Lucky Charms Cookies:
- Preheat oven and line a rimmed baking sheet with parchment paper
- Mix together the wet ingredients, set aside
- Mix together the dry ingredients including the crushed cereal but not the marshmallows or white chocolate yet
- Combine the wet and dry mixtures then stir in the white chocolate chips, unicorn chips and the Lucky Charms Marshmallows
- Place rounded spoonfuls of cookie dough on the prepared baking sheet and bake for 9 minutes
The cookie dough comes together really quick!
How to add marshmallow to the top:
- Bake cookies for 7 minutes remove baking sheet from oven and carefully add colorful marshmallow pieces (about the size of mini marshmallows) and some extra unicorn chips to the top of each cookie
- Bake for another 2 minutes then remove from oven
- Once removed I like to swirl the colorful marshmallow together to get a tie dye cookie effect- but you don't have too!
Add marshmallows on top when you are almost done baking.
How to stuff the cookies with marshmallow:
- Stuffing the cookies with marshmallow is much harder to pull off that it seems because the marshmallow will find any opening in the cookie and ooze out if it can
- Scoop out two balls of cookie dough and place half a large marshmallow, or a few small marshmallows in between them. Form a large cookie dough ball around the marshmallow and place on the baking sheet. Repeat.
- Refrigerate baking sheet with dough on it for 20 minutes.
- Bake for 13-15 minutes or until just golden brown.
- Remove from oven and allow to cool for 5-10 minutes.
You can also stuff the cookies with marshmallows.
For stuffed cookies: Why did my marshmallow leak out? It’s not gooey anymore.
Either you didn’t refrigerate the dough on the baking sheets or the marshmallow wasn’t encased in the cookie dough well enough- like there was a hole it melted out of.
I’ve noticed if there is too thin of a layer cookie dough over the marshmallow before baking the cookie will crack as it bakes and the marshmallow will leak out that way.
I also don’t recommend adding extra Lucky Charms Marshmallows pressed on top because when baked they get disfigured and don’t look cute. Plus sometimes they will melt completely and leave a trail of marshmallow smear that isn’t pretty.
Stuffing them marshmallows is a little more tricky.
How many cookies does this make?
It makes 3 dozen regular cookies or 14 large stuffed cookies.
What are the high-altitude adjustments for these cookies?
Decrease the white and brown sugar to ⅔ cup each and increase the flour to 2 ½ cups.
Lucky Charms pieces, Lucky Charms Marshmallows, Unicorn Chips, Rainbow Marshmallows - where to find them?
There are so many Lucky Charms items you can use in these cookies!
At my most recent trip to the store I found so many Lucky Charms items and fun colorful items that I wanted to try out for this recipe! Plus if I tried them then I figured you wouldn't have to buy all of them either.
I found all these items in the baking aisle at Walmart- and all really close to each other.
The Lucky Charms marshmallows- like the ones from the cereal box, worked fine in the cookies but if you eat them plain (of course I tried them!), the aren't crunchy like the ones in the cereal. They are soft and it was weird. But like I said they worked fine being baked in the cookies.
Lucky Charms Marshmallows- the large ones- love them! They are tasty and have color all the way through the marshmallow and make for a fun melted marshmallow topping and is what I used in the pictures.
Unicorn Chip- tastes like white chocolate chips but are in the super fun colors of purple and pink- perfect for a fun Lucky Charms Cookie Recipe.
Rainbow Marshmallows- they are fun colors, they do have a weird aftertaste if eaten straight from the bag, but when baked taste fine. The colors aren't as vibrant as the Lucky Charms large marshmallows but are still fun. They also don't swirl as well as the Lucky Charms marshmallows.
I love how colorful these cookies are!
Did you buy the Lucky Charms Marshmallow pieces or pick them out of the cereal?
I picked them out of the cereal by hand and used some from the store. Both worked well.
Can I use a normal white marshmallow?
Absolutely!
One of the funniest cookies ever!

Lucky Charms Cookies
Ingredients
- 1 cup butter slightly softened
- ¾ cups white granulated sugar*
- ¾ cups brown sugar*
- 1 teaspoon vanilla
- 2 large eggs
- 2 ¼ cups flour*
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 ½ cup crushed lucky charms cereal no marshmallow pieces
- 1 cup Lucky Charms Marshmallow Pieces or more if you want
- ¾ cup white chocolate chips
- ¾ cup unicorn chocolate chips*
- Colorful marshmallows cut in half for top if using
Instructions
- If you live at high altitude see baking notes below for adjustments! *
- Preheat oven to 375°F and line a baking sheet with parchment paper.
- In a mixer or with a hand mixer and the paddle attachment mix together the butter, white sugar, brown sugar, and vanilla. (1 cup butter, ¾ cup white sugar, ¾ cup brown sugar, 1 teaspoon vanilla)
- Add in each egg, on at a time. Mix in each egg completely before adding the next. The mixture should get lighter in color and thicker. You may need to beat on high for a minute or so to get everything well mixed. (2 eggs)
- In a small bowl mix together the flour, salt, baking soda, and crushed cereal pieces. (2 ¼ cups flour, 1 teaspoon salt, 1 teaspoon baking soda, 1 ½ cup crushed cereal pieces)
- Add flour mixture to the butter mixture and mix on medium high until fully incorporated.
- Stir in the white chocolate chips, unicorn chips* and Lucky Charms cereal marshmallows. (¾ cups white chocolate chips, ¾ cups unicorn chips, 1 cup Lucky Charms Marshmallows)
- Place rounded spoonfuls on the prepared baking sheet.
- If just baking the cookies like normal (no marshmallows on top), bake for 9 minutes.
- If wanting to add melted marshmallow and unicorn chips to the top bake for 7 minutes, remove from oven, place marshmallow pieces and a few unicorn chips to the top, bake for another 2 minutes, then swirl the marshmallow for a tie dyed look.
- If wanted to stuff the cookies with marshmallow: roll out the cookie dough into balls. Then take ½ of a large marshmallow and place in between two cookies. Mash the two cookie dough balls together to form one large cohesive cookie.Place cookies on parchment. Since they are so large, I only put 6 on each baking sheet.Refrigerate baking sheet with cookies on it for 20 minutes before baking.Bake for 13-15 minutes or until just starting to turn golden brown.
- Enjoy!
Notes
*For high altitude adjustments: decrease brown sugar to ⅔ cup, increase flour to 2 ½ cups *If you don't have unicorn chips just replace with more white chocolate chips
