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!

Chocolate Chunk Marshmallow Cookies
It hasn't even been a day since I've made these chocolate chip cookies and my kids have asked when I'll make them again. I call this cookie a huge success! They use simple ingredients and really quick to make.
Ingredients in Chocolate Chunk Marshmallow Cookies
- Unsalted Butter - softened butter is best for this recipe. It's important to not use melted butter as it will cause the cookies to spread. Slightly softened butter is best!
- Brown Sugar - brown sugar helps make the cookies chewy
- Granulated Sugar
- Egg
- Vanilla Extract
- All-Purpose Flour
- Baking Soda
- Baking Powder
- Salt
- Chocolate Chunks - can be substituted for chocolate chips
- Mini Marshmallows - it's best to tuck the marshmallows into the dough before placing them on the cookie sheet. This will help prevent any marshmallows from melting and sticking to the pan.
What's Needed to Make These Cookies
- Cookie Sheets
- Measuring Cups and Spoons
- Silicone Mats - helps prevent cookies from sticking to the sheets and makes for easy cleanup.
- Mixing Bowls
- Medium-sized cookie scoop

How to Make these Chocolate Chunk Marshmallow Cookies
Preheat the oven- Preheat to 350° and spray a cookie sheet with non-stick spray.
Combine the wet ingredients- Beat together softened butter, brown sugar, and granulated sugar until smooth. Add in egg and vanilla extract and mix until combined.
Mix in the dry ingredients- Slowly add in flour, baking soda, baking powder, and salt. Gently blend ingredients together without over mixing.
Stir in the chocolate chunks and marshmallows- Using a spoon, gently stir in chocolate chunks and mini marshmallows.
Scoop the cookies onto the cookie sheet- Using a cookie scoop, drop them onto greased cookie sheet.
Bake for about 11 minutes or until the tops and edges of cookies are golden.
Let the cookies cool before moving to wire racks to cool completely.
TIP: Parchment paper helps prevent the marshmallows from sticking to your pan.
When scooping the cookies, tuck the marshmallows into the inside of them so they are not touching the pan to prevent the sugars from melting.

These cookies turned out amazing. We only put in 1 cup of marshmallows and 1 cup of chocolate chips and it turned out great. The only thing is the cookies spread out a little too much, so next time I might add a bit more flour!
Sophie says
@Caitlin, you should chill it

Rachel says
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 🙂
Kathleen Gormal says
sounds great. I will check back later today to see how you updated it. thank you again ? and keep doing great things with gooey stuff! I live for gooey!
Madeleine says
For these cookies how do I store them to eat a day later?
Dana says
In an airtight container 🙂
Halia says
These cookies are so good! I made them for a school fundraiser but I ate half of them!
I ended up only putting 1/2 cup of marshmallows to reduce the sweetness

Dana says
So glad to hear that you enjoy them! I am guilty of the same thing 😉 It's hard to turn down a delicious cookie!
Emily says
You mentioned adding more chocolate chips and marshmallows to top the cookies. When do you add them? Can you share more about that?
Dana says
Yes, after they come out of the oven I top them with additional chocolate chips and marshmallows. 🙂
Leigh says
Do I need to chill the dough before scooping onto the cookie sheet? Or would that mess with the marshmallows?
Dana says
Chilling the dough would help keep their shape. Since they're being baked, the marshmallows will be fine. 🙂
Anona Williamson says
Love this recipe! I used exact ingredients. They taste wonderful! My cookies didn’t turn out flat and thin as yours did in your picture. Mine were more like a soft-batch cookie that was gooey. I didn’t chill dough. I did use parchment paper as well as without. They turned out the same both ways. I’m thinking maybe the reason they didn’t turn out as flat as yours did, is because you didn’t list specifically what kind of brands you used in your recipe. Sometimes that will altar how a recipe turns out. Using chocolate chips instead of chocolate chunks is going to make a difference in texture. I used semi sweet chunks. You didn’t list semi sweet or dark. I will make again, thank you!

Jules says
Definitely don’t add the amount of marshmallows all at once. For cookies that don’t stick to the pan like a hot mess, place your balls of dough on the pan first, and tuck 2 to 3 marshmallows in each. This helps prevent the puddling that some people are complaining about.

This was very good, I suggest adding a tiny bit of sea salt on top after it’s baked. It’s quite sweet but amazing.

Ck says
These turned out to be delicious. However, there are a few recommendations I would make. First, would be to refrigerate the dough for about 15- 30 minutes prior to baking. I found that the cookies I made from the dough I refrigerated for 30 minutes stayed in a more uniform shape than The ones made from the dough that was not chilled. Second, I would line a baking sheet with parchment paper or a silicone baking pad. I would not use baking spray or anything of the sort and bake cookies directly on the sheet. At the baking temperature, the marshmallows will almost completely melt. And if you've ever burned sugar while making candy, you know what a mess i'm talking about.
Other than those two modifications, I think the cookies turned out lovely. My 5-year-old daughter loved them. And The cookies I made with the unrefrigerated dough ended up making a lovely addition to the homemade vanilla ice cream I was making.

Thanks for sharing your recipes. May I know if the oven temperature is in degree celsius or Fahrenheit?
Dana says
It is in Fahrenheit 🙂
Jasmine C says
This is now my go-to choc chip cookies recipe! Admittedly, I accidentally overmixed the marshmallows on my first try- and now I do it on purpose; makes for the crispiest-on-the-outside-chewy-gooey-on-the-inside cookie and that’s just the way I like em. Cooking on parchment is the way to go- they pop right off once cool. I also have made a batch, rolled them into 1-2inch balls and popped them in the freezer so I can bake as wanted (otherwise I’ll eat the whole batch in a day!) they always turn out great!
Dana says
I'm so happy to hear that you enjoy these cookies! Thank you for sharing your tips as well. 🙂
Lily says
Hi! What type of flour do you use in this recipe? Looking forward to try it soon ?
Dana says
I use all-purpose flour - enjoy!
Hilal says
Hallo from Germany! My family and I love these cookies ?
Dana says
Thanks for sharing that you enjoy these cookies, I'm happy to hear it! 🙂
Christine says
Hi Dana,
I like to make 1/2 lb mega cookies in many flavors. I am having difficulty baking my choc chip marshmallow cookie. It spreads out to much while baking even with freezing it for several hours. Any suggestions?
Dana says
There isn't enough flour in this recipe to make mega cookies. You would need to add more flour to prevent the spread. Hope that helps!
Laura says
This looks so good! I am aiming to make them next week. How big are your cookie balls after you scoop it out? My cookie scoop makes one-oz scoops.
Dana says
Hey Laura,
I use a #40 cookie scoop with these cookies.
Mike says
@Dana, Loved these cookies! Thanks for the recipe! -Mike in Rhode Island
Ashley says
I've been in search of the best chocolate chip cookie and finally found it!!! Made them for the first time tonight and they were a HUGE hit with both the kids and the grown ups!
Dana says
Thanks for sharing. I'm happy to hear that everyone enjoyed them!
Rachel says
Not impressed with these at all. The marshmallow melted and made a mess of the entire pan. The melted marshmallow caramelized and became very sticky and crunchy on the bottom of the cookies. Didn't look very appetizing either.
Dana says
There are some tips within the recipe post that recommend parchment paper to prevent the marshmallows from sticking. Also, pushing the marshmallows into the cookie dough so that no marshmallows are peeking out is a great help as well.
Amber says
I just baked these cookies for the family and we all love them. They baked so well and taste great. They look amazing as well! Very gooey when warm .
Dana says
So glad your family enjoyed these cookies!
Sarah says
Sooooo good! I did increase the amount of flour to 2 cups so I had more of that to work with. I also decreased the amount of chocolate chips and mini marshmallows to just 1 cup. Finally, I used mini chocolate chips. Thanks for the recipe!
Ann says
These cookies are insanely good!! I followed the recipe and made smaller cookies (yielded 32) . I did not reduce the baking time; baked for 11 minutes. Also, I had a hard time folding the chunks and marshmallows in so set mixer to low.
Savita says
Chunks and marshmallows added so much depth to these cookies. Can't get enough of it.
Ann says
I made these for a treat for our camping trip this past weekend, and I brought none home with us! Was enjoyed by all!
Michelle says
These cookies turned out to taste great. The only thing: USE PARCHMENT PAPER TO SAVE YOUR COOKIE SHEETS. The marshmallows create a sticky mess that is hard to remove from your pans, even greased!
Laura says
While delicious, they are not attractive. They flatten out (even after refrigerating for an hour) and they make a mess. Would not make again…sorry.
Marie says
I made sure the marshmallows were covered with the cookie dough to prevent the marshmallows from leaking out of the bottom and I chilled the dough. I used parchment paper and they came out great. Kids loved them.
