These Fruity Pebble Marshmallow Cookies are an ooey-gooey delight! I love a soft, yet chewy cookie and this one is perfect!

Fruity Pebble Marshmallow Cookies ~ So gooey and sweet!

Sometimes cookies just need to happen.

And typically mixing cereal into a cookie wouldn’t be my first thought…but really why not?

The idea for these cookies came from my friend Amanda, who said she tried a similar cookie at the Momofuku Milk Bar in NYC…they way she described it sounded like perfection.

So I went ahead and looked up the recipe to make…well…it was a little complicated. And I wasn’t in the mood for a complicated cookie…so I dumbed down the recipe.

The idea is the same..Fruity Pebbles and marshmallows in a cookie, but the recipe is totally different…and way easier.

I LOVED these…I mean, I haven’t ever had the Momofuku version, and I am sure those are amazing too.. but easy wins for me most of the time!

I posted an image of the process on Instagram, and immediately got a text from Kristan asking what the cookies were! Turns out she had JUST made a similar cookie using Frosted Flakes! How hilarious!! SO definitely hop over and check out her version of this! Can’t wait to try those!

In the meantime, let’s discuss…

Has there ever been a prettier cookie dough?

And don’t forget about the marshmallows!

The secret to making cookies with marshmallows is to make sure they are pretty contained in the dough. If they are left on the bottoms or edges they will melt out and cook on the baking sheet, making a crunchy candy-like texture. Oh, I’m not complaining about that..actually I kind of like the chewy/crunchy texture a melted marshmallow makes, but if you want your marshmallows intact, keep them on the inside of the dough!

This is a fairly sturdy dough too, to hold up the melting marshmallows.

How perfect do these look?

  1. Loved these cookies!!! Made them for my daughter’s friend when she came home from deployment and they ate them all!


    I wasn’t a fan of these. I thought I’d give them a try for the sake of trying something completely different. The marshmallows ended up completely melted and 100% disappeared from the cookies and the cookies spread out out way too thin to even keep their shape. The dough actually tasted much better than the cookies themselves.
