Cookies, made to taste like lucky charms cereal!
Comin’ in hot just in time for st patrick’s day. I do already have an ice cream and some cookie bars, but I couldn’t resist creating a rainbow colored, chewy and crispy edged cookie. Those kind of recipes are my calling!
“Hearts, stars and horseshoes
Clovers and blue moons
Unicorns, rainbows and
tasty red balloons!”
I recognize I could’ve gone with the usual – just use regular cookie dough and add the mallows but I really wanted to double down on that signature ‘lucky charm’ flavor.
For these I do, of course, add the marbits (they get gooey and leave such colorful marks on the cookies as they melt) and I am also using the brown rice cereal bits as well. We’ll use quite a bit of it, grind it up and add some in the dough then roll the cookie dough in the rest of the crumbs and some of the marbit dust for a little more flavor.
One thing you might be surprised at is the use of powdered sugar instead of granulated sugar. I’ve done this to aid in getting the thin and crispy edges while keeping the centers soft and gooey – just like those globs of colorful mallow goo!
As far as texture, this recipe has roots in my bakery style chocolate chip cookies.
Lucky Charms: You’ll want a 10 oz box (not family size) and err, don’t be made at me, but you’ll have to separate the mallow bits from the brown cereal.
Sugars: We’ll do a mix of brown sugar (light or dark is fine – but don’t use organic which is not as moist) and powdered. While unconventional for cookies, I like using the powdered sugar here because it makes the centers more tender and chewy.
Flour: Any all purpose flour will do, I used King Arthur’s AP which has a protein content of 11.7%, so I’m betting a lower protein will cause more spread. If you are using something that has 11 or less, add another 2 tablespoons of flour.
Milk powder: This is a flavor enhancer, I like a malted milk powder because it gives more of that ‘cereal’ taste but a regular non fat dry milk powder will work too. This is optional.
Start by melting the butter, careful not to let any sputter out less you lose some fat necessary for the cookies
Important: Don’t leave the marbits (marshmallows) out for too long or they will hydrate and start to stick together.
Grind the rice cereal into a fine powder
Whisk the butter and sugar together, then warm the mix in the microwave for 30 seconds
Whisk until it’s thick and shiny.
Add the egg and yolk and whisk to combine.
Sift in the powdered sugar and whisk until you have a smooth mixture:
Add the flour, leavening, and the ground rice cereal
Once it’s mostly combined, add the marbits and stir until mixed
Cover the dough and set in the fridge for two hours, or more, to hydrate and firm up.
When ready to bake line two cookie sheets with parchment paper (a little grease helps the paper stick).
Scoop the dough into about 2-2.5 tablespoons per cookie, leaving space for them to spread.
Bake until the edges are set and golden and the middles are matte, about 12 minutes.
Tip: sometimes when there’s a concentration of marbits they will all melt together and make the cookie spread quite a bit in that one area. You can fix this by scooting the cookies, while still hot, back into place using an upside down bowl.
Instead of melting the butter, have it softened instead. You’ll want to use either the stand mixer or a hand mixer to cream the sugar and butter together for at least 3-5 minutes. Proceed as directed. They will be a little less chewy in the center and have a little less flavor but otherwise be fine.
The dough itself will keep in the fridge overnight but don’t leave it any longer or it may dry out. If you want to make them days ahead of time, make them up to the point of scooping and dipping in the crumbs, then place them on an open plate or cookie sheet and freeze them for 15 minutes until solid.
Then transfer them to a ziplock bag and freeze until you want to bake. If baking from frozen the cookies will need another couple of minutes in the oven.

Made a double batch so I could share the magic! A wonderfully chewy cookie with a great cereal flavor. Everyone’s raving about them!
Excellent, fun cookies! Feel like the texture was better on day 2, soft with a nice chew.
These cookies are beautiful and tasty! They’re also well balanced so that they’re not too sweet. Thanks for the recipe!
Another winner!
I love this recipe! Is there a way to reduce the sweetness and sugar without affecting the finished cookies too much?
Amazing! I love to try new recipes, so I rarely remake one too soon, but I’m already planning on when I’ll make these again! I made them for a party and got excellent reviews from everyone. They’re perfectly chewy, have a unique malt and cereal flavor, and are easy to make. Definitely a repeat recipe!
Two words: magically delicious! The marbits for the most part hold their shape and color, so they add an irreplaceably fun element to these cookies. The cookies themselves taste wonderful thanks to the ground up cereal, so they’re not just a cookie with marbits; they are true Lucky Charms cookies! I would recommend making sure to have plenty of dough to house the marbits in each cookie dough ball, because some that were on the outside edges of my cookies melted into scary-looking sugary spots. Surprisingly not too sweet either!
Not sure why I didn’t realize it until I tasted the result that this is essentially a fancy sugar cookie…I mean that in the best way possible though! I brought these to work and they disappeared faster than anything else I’ve brought in. I’ll definitely be making these again!
Just wanted to double check that by powdered sugar you mean icing sugar? Thanks!
yup, they’re the same
I just love that you left instructions on how to portion and freeze! I love doing this esp with cookies because with just the two of us we don’t want a huge batch of cookies to just mindlessly eat! I hope you will continue to do this!
Hi Sarah! I usually do – it’s in all the chocolate chip cookie recipes. I’ll make a note to do it for them all going forward =)
I would love to try making these, so could you specify which size should be used for the cereal? Looks like there’s 10.5, 17.6, 18.6, 18.8, and 26.1 oz box sizes. Thanks
the 10.5 oz box should be enough
