Surprisingly easy brownie-like chocolate marshmallow cookies are a fun twist on a classic double chocolate cookie! Chewy, chocolate-y, and sweet.
These are not the ultra crinkly, idealised brownie cookies – honestly, for the average reader to successfully make those instagram cookies is a bit ridiculous. Every step needs to be timed absolutely perfectly, the temperature needs to be just right, and the oven can’t be off at all. (And there’s no taste difference, let’s be real.)
They are, though, truly excellent chocolate marshmallow cookies with a brownie-like texture. There’s definitely some crinkling there and a wonderfully chewy, fudgy interior. The marshmallows brown slightly during baking and the whole thing ends up tasting like hot chocolate in cookie form.
With just a dozen ingredients, including salt, these make good use of that half bag of mini marshmallows you forgot about in the summer. It’s a mix of the best of summer and winter – campfire with curling up by the fireside, roasted marshmallows and hot chocolate.
P.S. the baking paper looks a bit funny because it’s reused. Did you know that you can use parchment paper multiple times? We use it until it starts falling apart before composting.

Ingredients
Method
Preheat the oven to 350°F (180°C) and line two large baking sheets with parchment paper.
Place the butter and chocolate into a small saucepan (use a double boiler if needed) and melt over very low heat. Whisk to combine and set aside to cool slightly.
Place the flour, cocoa, baking powder, baking soda, salt, and vanilla powder (if using, not extract) into a bowl and whisk to combine. Set aside.
Add the sugar and eggs to a large bowl and beat with an electric mixer for five minutes, or until very smooth and light in colour.
Beat the cooled melted chocolate into the sugar and egg mixture until combined.
Stir in the flour mixture with a wooden spoon or spatula until just mixed – don’t over mix. The dough will be very soft, almost like cake batter.
Gently fold the chocolate and mini marshmallows into the dough. Cover and let the dough rest for thirty minutes.
Scoop the dough out onto the prepared baking sheets, leaving about 5cm (2 in.) between each cookie. Bake for 10-12 minutes, or until the cookies are cracked and the edges are just firm to the touch.
Cool the cookies for about ten minutes on the pan before removing to cool fully on a rack. These will keep in an airtight container for about a week and freeze well.
Tips and Notes
The butter and chocolate mixture are shown being melted in a small saucepan, rather than with a bain-marie. If you have an induction stovetop that can be heated very minimally, it’s fine to use a saucepan and melt over the lowest temperature. Otherwise go for a double boiler to avoid burning the chocolate.
The chocolate used is 55% cacao solids, and this makes for a properly brownie-like cookie. Higher cacao solids will mean a less sweet cookie – it may not have the same texture, but it’ll still be good. It’s a bit of a toss-up depending on how much of a sweet tooth you have.
It’s not mandatory that the dough rests before baking, but it will make for a much better cookie. If you’re impatient, you can bake immediately. If you want a better texture, then wait half an hour before scooping and baking.
To get a head start on holiday baking or if you just like to have a stash in the freezer, note that these freeze spectacularly. They’re almost as good straight from the freezer as they are fresh – pair with sweet cream ice cream for some fantastic ice cream sandwiches.
Substitutions
We haven’t tested these with GF flour, but these gluten-free brownie cookies would be a good option – just add marshmallows to the mix. A blend, like the one from Bob’s Red Mill, would probably work here, though (but it’s untested).
Use a good vegan butter for a dairy-free option.
As mentioned, this recipe uses 55% chocolate, which is about equal to semi-sweet chips or baking chocolate. You can use darker chocolate if preferred but don’t switch to milk chocolate for the cookie base (any type of chips/chunks can be mixed in).
Regular marshmallows can be used for the minis if you chop them up. We used Dandies for a vegetarian option.

Maria João Fragoso says
As soon as I pored in the milk, it whittled… I’m so sad :(
Alexandra Daum says
Hi Maria, not sure what you mean by whittled? If it’s looking curdled, it’s probably just the coconut oil getting hard due to cold milk or other ingredients and they’ll still bake up fine.
Robyn says
I made these and they turned out awesome. The chocolate I had was a little bit of leftover semi-sweet chocolate chips and a bag of 70% cocoa chocolate chunks, so it was a tad less sweet but it still tasted fantastic. I did not have vanilla powder and then forgot to put vanilla extract in, and again, they still tasted awesome.
Alexandra Daum says
I’m so happy to hear that, thanks Robyn!
Rae says
Just made these and the flavor was great for a brownie cookie and my nephews keep sneaking extras! But I ran into some trouble with the marshmallows. I made the recipe as indicated with semi sweet chocolate chips and Kraft mini marshmallows – the only variation was that the dough sat 15-30 extra minutes before baking. The marshmallows completely melted into a clear sugary mess while baking. This made some of the cookies spread out super thin and fall apart with gooey spots. Not sure what the trick is for getting those beautiful browned marshmallows. The cookies that missed a marshmallow piece turned out great.
Alexandra Daum says
Hi Rae, glad you liked the cookies despite the marshmallow issue. We are currently testing to try to solve this, as it seems to vary from brand to brand! The recipe will be updated once we sort it out and we can say which types work well and find some ways to mitigate the melting problem with others.
Emily says
I also had an issue with melty marshmallows, which made for a messy bake. I used regular size jet puff brand marshmallows quartered into smaller bits.
Alexandra Daum says
Hi Emily, there does seem to be an issue with jet puff marshmallows – I think it’s because they’re a lot softer than many other brands. A drier marshmallow works best here.
Vaughn says
I’m a fairly experienced baker and usually just edit my go-to cc cookie recipe to make them chocolate and add whatever extras I want. This time I decided to try something different and I am sad to say it was a let down. The process is similar to how I make brownies, and predictably, the results were basically pools of brownie-like puddles that my children named “cow patty cookies” because of the flat, spread out, lumpy look. They tasted fine but definitely lacked a chewy, cookie-like consistency or a nice presentation.
I poured the remaining batter I to muffin tins and the results were better: small cakes.
Alexandra Daum says
Hi Vaughn, did you change anything about the recipe? I’ve made these over a dozen times (as recently as a couple of weeks ago to give as Christmas gifts) and have never experienced anything similar to what you’ve described.
Sharlee says
I made these tonight and i wouldn’t change a thing.. I couldn’t** wait the 35 minutes to get these in the oven so they chilled for 10 and still turned out great, im sure if i had let them chill longer they would have had been even fluffier.
Thanks for the recipe, will for sure make them again.
(PS for those saying the recipe produced flat cookies.. i’m going to guess you did what i did, to no fault of the author.. and didn’t chill the cookies.. don’t leave a poor review if you don’t follow the recipe)
Sgraf says
Well, my cookies — albeit quite tasty — are flat. I did not chill the dough. As a result, the cookies are flat and the marshmallows disappeared.
I’m planning to make these again and add the step of chilling the dough. I think they’ll be perfect! Thanks for the recipe!
