These Chocolate Marshmallow Brownie Cookies are easy to make and full of chocolatey flavor. They come together quickly and taste absolutely delicious.
Chocolate Marshmallow Brownie Cookies

There is a little restaurant close to our house called Cutler’s that makes the most amazing sandwiches and cookies! Their cookies are seriously to die for.

Well, I was craving some of their cookies, but my kids were taking a nap and I couldn’t leave the house, so I came up with my own recipe.
It is so delicious. I almost like it more than the restaurant because I can make them from home while the kids nap, and I don’t have to put on real pants.
They are so rich and delicious, that you can barely finish one. It’s a whole lot of chocolate, so if you have a chocolate loving friend, you may want to let them know about these Chocolate Brownie Marshmallow Cookies.
 The marshmallows will kind of puff up like this.
But after you frost them, they will look like this. The chocolate kind of covers them up and smooths it all over.

do these cookies freeze well?

These recipes freeze great. We recommend putting them in an airtight storage container, or a thick ziplock bag, with all the air sucked out of it.

We recommend only freezing them for a month at the longest. To thaw them, we recommend placing them in the fridge or on the counter, 24 hours before serving.

We wouldn’t recommend microwaving them because it will ruin the texture of the frosting and marshmallows, making them chewy, and not soft.

    I was going to leave you a nice comment, but now I don't have time. Now I need to run straight to my kitchen and turn on the oven so I can make these cookies. I hope you understand why I can't say thank you for giving me this recipe, and why I can't even finish this comm... ;)

      I just finished frosting these delicious cookies and felt compelled to comment. They are very easy to make using the cake mix and they came out so soft! We have a Cookie Connection in town and these taste just as good - now I have to find people to share them with or I'll eat the whole batch!

    @Katie - people here in Utah where I live always say a "cube" which really means a square, but they mean a stick - which is a half cup. :)

      Ha ha! Sorry about that! I learned that a cube of butter is a Utah thing . . . anyone, it's just a stick of butter (or 1/2 cup). :)

    These are so good. Remind me of my childhood. I could not find a milk chocolate cake mix so I just added some powdered milk to the mix. To die for!

      You will get right around 3 dozen. Try to keep your dough balls close to 1 inch and you should be fine.

      They freeze great. Just have them in an airtight container or a thick freezer bag.

    I love trying new recipes! I too thought these looked wonderful and thought they would be great to make for my work cookie exchange. They sounded really easy to make and since I was going to have to make almost a 100 cookies, I thought these would be perfect. However, after the first batch I quickly changed my mind. One of most frustrating thing was "rolling" them into balls. The cake mix/eggs/veg oil created a very sticky taffy like mixture. Trying to "roll" them into balls was absolutely impossible! You can't even get the batter off your fingers. Cooking the cookies for only 5-6 minutes was no way close to long enough time before putting the marshmallows on, they were still very doughy. The marshmallow piece wasn't that big of a deal, but I found myself having to smash the cookies down inorder to get them to stay on top. Also, the frosting was terrible. I tried making the frosting a few different ways by decreasing/increasing vanilla and even powder sugar. I would have been better off using store bought frosting. Of all the recipes I've ever tried, I have never before written a comment, but I was so disappointed and frustrated with my experience that I felt I needed to share. If you're going to make these yourself, be prepared to spend more total time to create them and if you have a favorite frosting recipe I would recommend using it instead.

      I had the same problem with the batter - I'm curious if it's the brand of cake mix. But I simply scooped the batter out with a spoon, and then scraped it off onto the baking sheet with another spoon - and that worked just fine. I'm going to try these again with a different brand and see if that makes any difference.

    These are my familes favorite cookies! We have a similar cookie shop called The Cookie Connection, they make a similar version of these and they are delicious! I found your recipe and was thrilled to be able to make this yummy cookie at home. I followed your recipe exactly and they turned out perfect! I never had any problems rolling the dough into balls, the marshmallows can be tricky but that is not a big deal. And this icing is one I have used for years as a basic frosting. This is such a simple recipe, I really don't see how anyone can have problems with it.

    Just made these and they were a HUGE hit!! My question is that my frosting was too thin, I made it as per recipe directions but still never really set up..... any suggestions? It was wonderful tasting and we still used it, but could have been thicker? More stiff?

      Hi Kristen. You could add a little more powdered sugar to the frosting if it's too runny. We updated the recipe slightly, so hopefully that will help.
