Ingredient Notes
Full recipe and ingredients are in the recipe card below. Feel free to scroll through this section to view certain key ingredients we’re using!
- Butter: I always use unsalted butter. Pull out 2 hours before baking. You know it's ready when you lightly press your finger in and a slight indent is made.
- Egg: Pull the eggs out 2 hours before baking. Having an egg at room temperature maximizes baking results and helps mix into the batter better.
- Chocolate chips: I used high quality semisweet chocolate chips for this recipe. You can also use dark chocolate chips, chunks, chopped chocolate, or mini chocolate chips. However, don't use milk chocolate chips as the cookies will turn out too sweet.
- Marshmallows: Cut regular sized marshmallows in half, one half is used per cookie.
Expert Baking Tips
Here are my top 5 tips for successful Chocolate Chip Marshmallow Cookies
- Sealing the cookie properly - Cover the cookie dough over the marshmallow completely. Check out the video and photos down for a step-by-step guide. I’ve noticed if there is too thin of a layer cookie dough over the marshmallow before baking they cookie will crack as it bakes and the marshmallow will leak out that way.
- Use a gram scale - This helps you get the most accurate results. If you don’t have a scale, spoon gently into a measuring cup. Scrap any excess off, and make sure the top of the cup of flour is flat.
- Size of marshmallow - I recommend doing this with regular or jumbo sized. Use kitchen scissors to cut them in half. You can also use 2-3 mini ones marshmallows!
- Chill time: This recipe does require a 30 minute chill time, and it is mandatory. Chilling the cookie dough helps the cookie cook a little slower and the marshmallows to melt slower as well - which allows the marshmallow to stay inside the cookie!
Storing and Freezing
Store these chocolate chip marshmallow cookies in an airtight container on your kitchen counter for up to 5 days. They are best served warm!
The cookies can be frozen once baked. Store in an airtight container for up to 28 days.
The cookie dough may also be frozen in a freezer safe bag for up to 28 days. When ready, allow to thaw at room temperature completely before baking. This takes approximately 2 hours.

- Place into the refrigerator to chill for 30 minutes.
- Once chilled, bake at 350°F for 8-10 minutes. The cookies will look soft, this is because the marshmallow has melted into the cookie. Remove from the oven and allow to cool on your baking tray for 5-10 minutes! Moving them around immediately after baking will cause a sticky mess.
