STEP TWO: Add the egg and vanilla extract and use a whisk to combine. Next, add the flour, baking soda, and salt and mix until no large lumps of flour remain. Don’t over-mix!

Gently fold the chocolate chips and marshmallows into the cookie dough. Be careful not to rip the marshmallows.

STEP FIVE: Bake for 12-15 minutes or until they turn golden brown along the edges. Remove your chocolate chip marshmallow cookies from the oven and tap the tray on your counter to sink the centers.

Allow them to cool completely on the tray — this method will ensure that they finish cooking all the way through.

Store your creations in an airtight container at room temperature for up to 5 days.

What Are Brown Butter Chocolate Chip Marshmallow Cookies?

Brown butter chocolate chip marshmallow cookies are made with brown butter. You can make it by cooking unsalted butter until the milk in the butter solidifies and becomes brown.

While this method can take the flavor up a few notches in your cookies, I find that it isn’t necessary. As mentioned, I simply use brown sugar instead to get a similar flavor!

How Do You Keep Marshmallows From Melting In Cookies?

The key is in allowing your cookie dough to chill.

This is why I give you the option of chilling your dough overnight — that extra time in the fridge will ensure that the marshmallows firm up enough to be baked.

Just 30 minutes is long enough, but if melting is a real concern, I recommend that you leave them overnight.

What If I Can’t Find small Marshmallows?

I find that most supermarkets carry small marshmallows.

If your store is out of stock, you can use mini marshmallows instead! I don’t recommend breaking up a large marshmallow since it can melt before it browns.

Speaking of substitutions, I use dark chocolate chips but you can feel free to use whatever kind you like — or even simply chopped-up chocolate.

What Makes Cookies Fluffy vs Flat?

First things first, don’t skip the baking soda listed on the ingredient list below. It helps the marshmallow chocolate chip cookies rise so that they become soft and chewy.

You may also consider using room-temperature butter instead of melting it. This technique will cause air pockets, and the results are really fluffy!
