These Nutella monster cookies aren't quite like a classic gluten free chocolate chip cookie. Instead, they're like a cross between a nut butter cookie and an oatmeal cookie. Made with Nutella instead of the traditional peanut butter, they're a truly special treat.

What makes these Nutella monster cookies special?
Classic gluten free monster cookies are made with peanut butter and oats, and no traditional flour. They're big, thick, and chewy and packed chocolate chips and M&Ms (which are gluten free in the U.S.).
I've been baking more and more with oat flour, like in our oat flour brownies, so I know how useful it can be. Unlike most monster cookie recipes, our monster cookies are made with a combination of old-fashioned rolled oats, plus oats ground into flour.
That's what makes the biggest difference, and gives us more of a traditional thick and chewy cookie texture in these amazing Nutella monster cookies.

How baking with Nutella is different
These hazelnut-flavored Nutella monster cookies aren't made just by swapping Nutella for peanut butter in our original recipe. In a fit of hopefulness, I tried that, and the cookies spread into unintentional lace cookies.
Nutella is a nut butter hazelnut spread, but it simply doesn't behave in baking the same way that peanut butter does. It's a much thinner, even stickier spread.
The major difference in constitution between peanut butter and Nutella is that Nutella has a lot more sugar than even the most sugary jar of peanut butter. Sometimes, I can simply cut back on the sugar in a peanut butter recipe, and everything works out quite well. Like it did with our 3-ingredient Nutella brownies.

What else is different about this recipe?
Other times, it just doesn't work—like here. Instead, I had to add more oat flour, use granulated instead of brown sugar, and cut down on the sugar overall.
Since I couldn't use as much Nutella as I would have liked, adding some cocoa powder really helped deepen the flavor without changing the texture.
It was all worth it, though, since these Nutella monster cookies are rich with chocolate-hazelnut flavor. They're also still crisp outside and chewy inside, like the original.

Are M&Ms really gluten free?
As long as I've been baking gluten free (since 2004!), most M&Ms chocolate candies have been reliably gluten free. Sure, there are some unsafe varieties like the crispy M&Ms (made with crisp rice cereal that isn't GF) and the pretzel M&Ms which are made with, well, pretzels.
But other than those outliers, plain, peanut, peanut butter, caramel and most of the other M&Ms candies are gluten free—in the U.S. I've learned that, sadly, in Australia (and maybe some other countries?), M&Ms are not gluten free.
That is terrible news just in general since being able to buy a package of M&Ms at the grocery or convenience store has always been a fun, normal thing for my gluten free son.
If you can't buy gluten free M&Ms, do you have Sixlets available? As far as I know, they're gluten free everywhere.
If you can't find a candy-coated chocolate candy at all, you can simply use more chocolate chips. Or try another variety of chip in place of the M&Ms.

Popular ingredients & substitution suggestions
Dairy free
The only dairy in these cookies is from the unsalted butter and the M&Ms chocolate candies. In place of the M&Ms, try using more semi-sweet chocolate chips (and of course make sure they're dairy-free!).
In place of the butter, try Melt brand vegan butter or Spectrum brand butter-flavored nonhydrogenated vegetable shortening. I don't recommend using Earth Balance buttery sticks since they have a ton of moisture.
In place of Nutella, try using Nicciolata brand Dairy Free Organic Hazelnut & Cocoa Spread. I've purchased it before on Vitacost.com, but if you search around you can find it in a few different places.
They make a dairy-containing spread, too. If you order it, be sure you've selected the right one.
Egg free
In place of each of the two eggs in this recipe, try 1 “chia egg” (1 tablespoon ground white chia seeds + 1 tablespoon lukewarm water, mixed and allowed to gel). I haven't tried this recipe egg-free, though, so you'll have to experiment.
Oats
Oats can be replaced in baking. Oat flour should be replaced with quinoa flakes and the old-fashioned oats with something called “beaten rice,” but click through the link in the previous sentence for a complete explanation.
I only buy old-fashioned rolled oats, and then grind them in a blender or food processor as finely as possible for oat flour. For quick-cooking oats, I process them very quickly with just a few pulses in a food processor (a blender tends to grind oats into flour completely).
M&Ms

Hi, I’m sugar free for Medical reasons and Gluten free as well. Do you think I would be able to omit the sugar or add monkfruit in place of sugar. Thank you!
You definitely cannot omit the sugar, and I’m afraid Nutella itself has quite a lot of sugar, Rose. If you can tolerate that, you can try replacing the granulated sugar with Swerve granulated sugar replacement.
In Australia we have our biscuits very crunchy not chewy. Will these become crisp if baked longer.
You’d need a different recipe for a crispy cookie, Henny. Please use the search function and put in “crispy cookie”
HI Jennifer! Is it possible to use steel cut oats to make oat flour? Thanks!!
Hi, Karen (I’m Nicole :) I’m afraid I don’t think steel cut oats are appropriate for grinding into oat flour. They’re just not already processed enough to be ground into anything fine. Sorry!
I don’t know why most of my comments never end up getting through, must be a technological bug!
I made these with roughly chopped hazelnuts instead of the M&Ms. They were great!!
Those sound awesome, Anna Sophia! I can’t imagine why your comments haven’t gotten through, but this one did just fine. :)
I did the recipe and they were waaay runny. So I had to use 3/4 c Better Batter for them to set. Way rich and good, though!
Did you measure your ingredients by weight? Make any substitutions? The recipe works as written, and you see the video, Deborah, the dough is actually very thick.
Recipe doesn’t say to add the granulated sugar??
So sorry, Shannon. It’s fixed now!
Have you ever published your homemade Nutella spread?
I don’t make homemade Nutella, I’m afraid, Denise. The jarred stuff is what we use!
I am so excited to make these today!
Makes sense that Nutella misbehaves. It’s first two ingredients are sugar and oil, not nuts. It tastes mighty fine, though. Someday I’ll get around to making the dairy free versions I’ve seen online. We don’t do oats in our house, but like always, these cookies look amazing!!
That is so true, Donia! I have made my own chocolate-hazelnut spread before, and it was delicious, but I could not bring myself to make my own copycat Nutella since the ingredient proportions are so hard to live with. I have also made it dairy-free, and it’s good. But different. Which isn’t necessarily a horrible thing. :)

I love monster cookies!! thanks for this variation – I’m sure they will be just as loved and I do not care a hoot that you had to modify – it’s still GF isn’t! win, win, and win!
Thanks, Jennifer! Sometimes I can predict when I’m going to get taken to task, and sometimes not at all! ;)
xoxo Nicole
