Fruity Pebble Marshmallow Cookies ~ So gooey and sweet!

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

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?

That is a pretty dough! And a delicious looking cooking! I would never buy fruity pebbles to actually eat them but I think I could justify a box with the scrumptious looking cookies!!!

Wow! I just love how colourful they are and how the marshmallow goes all gooey. We don’t have fruity pebbles in Oz, but Im thinking maybe we could try this with Fruit Loops, a sort of similar cereal.. yum!

OMG I need to try them with Fruity Pebbles! I definitely made the Momofuku version but gluten free and with frosted flakes a couple months ago, and we still have mounds of the dough in the freezer. They’re SO good.

The cornstarch in the dough is interesting, I’ve never heard of that before! What’s its purpose??

April 23, 2014 9:02 pm

Wow… I’m just in awwwwww mode because these look so delicious. I want to whip up a batch right now! First, I better pick my jaw up off the table and stop drooling!

I held out three whole days before making these. Why did I wait so long??? This is my new favorite cookie! A chewy, fruity, sugar masterpiece!

I made these this week for a friend. They tasted great! Loved the fruity marshmallow combo. My only issue, my cookies spread significantly while baking. I’m wondering if I should have made the cookie balls and maybe refrigerated them prior to baking?
Thanks for the recipe!
