Have you ever tasted a bite of fluffy heaven? Well, imagine biting into a cookie that has the perfect combination of soft and crunchy texture, and topped off with a melt-in-your-mouth marshmallow.

Marshmallow cookies are truly a treat for the senses. They tantalize your taste buds with their sweetness and satisfy your cravings with their perfect texture. One bite of a marshmallow cookie, and you’ll be hooked.

You’ll need:

  • 2¼ cups of all-purpose flour
  • 1 tablespoon of cornstarch
  • 1 teaspoon of baking soda
  • ¼ teaspoon of salt
  • ¾ cup of salted butter, softened to room temperature
  • ¾ cup of light brown sugar
  • ¼ cup of granulated sugar
  • 1 large egg, room temperature
  • 1 large egg yolk, room temperature
  • 1½ teaspoons of vanilla extract
  • ½ cup of semi-sweet chocolate chips
  • 4-ounce bar of semi-sweet baking chocolate, roughly chopped
  • 1 cup of frozen mini marshmallows

PRO TIP:

Be sure that your marshmallows are fresh for the best results. Older marshmallows don’t melt as well when baked in the cookies.

Substitutions And Additions

CHOCOLATE: You can omit the chopped semi-sweet chocolate chunks from the cookie recipe and just add an additional ½ cup of chips. You can also swap out the semi-sweet for milk chocolate chips if you prefer. A combination of milk and semi-sweet chocolate is also a great option.

BUTTER: If using unsalted (or sweet cream) butter, then you will need to increase the amount of salt in this chocolate chunk marshmallow cookies recipe to ¾ teaspoons.

How To Make This Marshmallow Cookies Recipe

OUR RECIPE DEVELOPER SAYS

I highly suggest freezing your mini marshmallows before adding them to your dough. Because this is a thicker dough, the frozen marshmallows hold their shape better, making it easier to scoop out the dough balls. 

STEP ONE: Sift together the all-purpose flour, cornstarch, baking soda, and salt in a medium bowl. Set dry ingredients aside.

STEP TWO: In a large mixing bowl with an electric mixer or the bowl of a stand mixer fitted with a paddle attachment, beat the softened butter, light brown sugar, and white sugar on medium speed until light and fluffy.

STEP THREE: Add the egg and egg yolk to the bowl, one at a time, followed by the vanilla extract and beat for another 1 to 2 minutes or just until fully incorporated.

STEP FOUR: Add half the flour mixture to the bowl and mix on low speed just until incorporated. Repeat with the remaining flour mixture.

STEP FIVE: Using a large wooden spoon or plastic spatula, fold the semi-sweet chocolate chips, chopped semi-sweet baking bar, and frozen mini marshmallows into the cookie dough. The batter will be thick.

STEP SIX: Using a 2-inch cookie scoop, scoop out all the marshmallow cookies and place them onto a parchment-lined baking sheet. They can be close together because you need to place the cookie dough balls into the refrigerator to chill for at least 2 hours before baking. Refrigerate the balls of dough for at least 2 hours.

PRO TIP:

Be sure to keep your cookie dough balls in the refrigerator until ready to bake.

STEP SEVEN: Preheat the oven to 350°F. Line a large baking sheet with parchment paper.

STEP EIGHT: Place 4 to 6 cookies onto the prepared baking sheet, being sure to leave about 2 inches between each cookie.

PRO TIP:

When placing the chilled cookie dough balls onto the baking sheet, be sure that you have the side with the most marshmallow pieces on the top. If the marshmallows are primarily on the bottom, it will cause the cookies to spread a lot when baked. If your cookies spread a little, you can gently push the sides of the warm cookie back toward the center to reshape them.

STEP NINE: Bake cookies for 12 to 13 minutes or until lightly golden brown around the edges and the center is set.

PRO TIP:

Oven temperatures vary and may need to be recalibrated periodically to ensure they are accurate. Make sure to check your chocolate marshmallow cookies at the lower end of the recommended baking time.

STEP TEN: Allow the baked cookies to cool on the baking sheet for 10 minutes before removing them to cool completely on a wire rack.

How To Serve

These marshmallow chocolate cookies are so rich and decadent that they might just become your favorite kind of cookie. Enjoy them with a warm mug of homemade hot chocolate or whipped hot chocolate for an extra indulgent treat.

If you’re looking to balance out the sweetness of the cookies, consider serving them alongside some tart or tangy fruit, like sliced apples or berries.

And if you’re feeling truly indulgent, why not add a dollop of whipped cream or a scoop of vanilla ice cream to take your marshmallow cookies to the next level of decadence?

Storage

Just like most cookies, you can store these for later enjoyment. Here’s how:

ON THE COUNTER: This chewy cookie recipe is best enjoyed right out of the oven, but if you have leftovers, you can store them at room temperature in an airtight container for 2 to 3 days.

IN THE FREEZER: You can freeze the chocolate marshmallow cookie dough balls and place them into a freezer-safe zip-top bag to store for up to 2 months. I always suggest labeling your freezer bags with the type of cookie, bake temperature, and time. This makes it easy to bake your cookies anytime you want without pulling out your recipe for the baking instructions.

    My daughter declared “these are the best cookies EVER!” I bake all the time and these are now in first place. I never make cookies that require chilling. I always choose recipes that are fast. Decided to give these a try and they were worth the wait. I will be whipping up another batch this weekend!
