These Chocolate Chunk Marshmallow Cookies are ooey, gooey, and delicious. Add some extra texture and flavor to the traditional chocolate chip cookie by using chunks and marshmallows!
Ooey Gooey Goodness
I really enjoy making homemade cookies and I especially enjoyed making these. It was a lot of fun sprucing up the Plain Jane chocolate chip cookie! Adding marshmallows made the cookies really gooey and the kids loved them!
Watching the marshmallows bubble and ooze in the oven had my mouth watering long before they were ready to come out of the oven.
Get Ready to Bake
I like mega big cookies. Ridiculously big cookies. Cookies that so big that it takes two hands to hold them. If that's not your kind of cookie, you can easily drop by rounded tablespoons instead of by a medium-sized cookie scoop.
Of course, you'll have to adjust the baking time accordingly... either way you make them, they'll be delicious!
Softened butter is best for use for this recipe. Slightly softened butter will help prevent the cookies from spreading. As in any baking, when using melted butter it will cause doughs and batter to be runnier and therefore causing spread in baked goods.
Simply allow the butter to sit out on the counter for about 20 to 30 minutes before using it. Avoid using the microwave for the chance of overheating the butter.
When preparing the cookie dough and before placing the dough on the cookie sheets, tuck any marshmallow bits into the dough so that they are not peeking out of the bottom. Marshmallows will melt and stick to the cookie sheets if they are exposed.
Silicone baking mats or parchment paper are wonderful to use when preparing these cookies in case marshmallows sneak out during the baking process.
Cookies Out of the Oven
Let these cookies cool after coming out of the oven before transferring to a wire rack. This recipe makes a really soft and chewy cookie and moving them too quickly will cause them to fall apart.
It'll be tempting to dive into these cookies but they will continue to bake while they cool. Remember, good things come to those who wait... and these cookies are worth it!
These chocolate chunk marshmallow cookies are my kids' favorite and even they have patience before digging into those cookies!

Do you have any recommendations to prevent the marshmallows from oozing so much during baking time that they burn on the edges? I’ve tried to cook them for less time and even tried to make sure there were no marshmallows near the edges but nothing seems to work.
Dana says
Hi Rachel! One tip is to roll the cookies into a ball and to make sure the marshmallows are tucked into the dough so that the marshmallows don't spread out.
Kathleen Gormal says
Help! My dough had way too much marshmallows and chocolate chips. The cookies were flat as paper and with not nearly enough dough. I used a 10 oz bag of mini marshmallows and a 12 oz bag of chocolate chips. What did I do wrong? I tried the large and small versions of the cookies. Nothing turned out like a cookie should or like your pictures!
Dana says
Hi Kathleen,
I am not sure what could have gone wrong. I make these cookies for my kids all the time. I can only think of a couple of things that could have caused the cookies to be so flat. 1) The butter could have been too soft or close to being melted. This would cause the cookies to spread out and not hold their shape. 2) The baking powder could have lost its freshness. This could cause the cookies to not rise properly.
I'm sorry you are having issues with this recipe and I hope that I was able to help.
Kathleen Gormal says
You are very sweet and thank you for writing back so fast! I also wondered if my oven was too hot. It like pulverized the marshmallows. Do you use vegan marshmallows? I read on another site that they keep their shape better. My butter was very soft - out all night on the counter, but not microwaved or anything. I look forward to trying these again. thank you!
Dana says
I have not heard that about vegan marshmallows! But no, I use regular mini marshmallows. It sounds like the butter may have been the issue 🙂 You're welcome!
Dana says
Hi Kathleen! I wanted to update you to let you know that I changed the measurements for the chocolate chunks and the mini marshmallows. Sorry for the confusion, I always use the extras for topping the cookies! In fact, I have some in the oven right now because I wanted to make sure I was correcting the recipe to exactly how it is supposed to be 🙂
