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!

How to Make these Chocolate Chunk Marshmallow Cookies

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.

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.

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. 🙂

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!

Yay! I'm so happy to hear that! They're a family favorite of ours, too!
Caitlin says
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!
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.
