What Are Chocolate Marshmallow Swirl Cookies
A Chocolate Cookie with a Gooey Twist
Chocolate marshmallow swirl cookies are made by swirling marshmallow into rich chocolate cookie dough before baking. As the cookies bake, the marshmallow melts and creates soft pockets and swirls throughout the cookie, adding sweetness and visual appeal.
Why These Cookies Are So Popular
These cookies are popular because they combine two classic favorites—chocolate and marshmallow—into one decadent dessert. The gooey texture and dramatic swirl pattern make them especially appealing and fun to eat.
Are These Cookies Beginner-Friendly
Yes, these cookies are beginner-friendly. The dough is straightforward to make, and the marshmallow swirl doesn’t require precision. Even imperfect swirls bake up beautifully.
Ingredients for Chocolate Marshmallow Swirl Cookies

Chocolate Cookie Dough Base
The cookie dough is made with cocoa powder or melted chocolate, flour, sugar, butter, eggs, and vanilla. This creates a rich, fudgy base that stays soft after baking.
Marshmallow Swirl
Marshmallow fluff or mini marshmallows are used to create the swirl. They melt easily and blend into the dough while baking.
Optional Add-Ins
Chocolate chips, chunks, or a pinch of espresso powder can be added to intensify the chocolate flavor.
Tools You’ll Need to Make Swirl Cookies
Essential Baking Tools
You’ll need mixing bowls, measuring cups, a whisk or electric mixer, a baking sheet, and an oven. Parchment paper helps prevent sticking.
Optional Tools for Best Results
A cookie scoop helps portion the dough evenly, and a toothpick or knife can help create the marshmallow swirl.
How to Make Chocolate Marshmallow Swirl Cookies Step by Step
Preparing the Cookie Dough
Start by mixing the wet ingredients until smooth, then add the dry ingredients to form a thick chocolate cookie dough.
Adding the Marshmallow Swirl
Drop small amounts of marshmallow onto the dough and gently swirl it in using a toothpick or spoon. Avoid fully mixing so the swirl remains visible.
Baking the Cookies
Bake the cookies until the edges are set and the centers are still soft. The marshmallow will puff and melt as they bake.
Cooling the Cookies
Allow the cookies to cool on the baking sheet briefly before transferring them to a rack. This helps them set while staying soft.
Tips for Perfect Chocolate Marshmallow Swirl Cookies
How to Keep Cookies Soft
Do not overbake. Removing the cookies while the centers are still soft ensures a fudgy texture once cooled.
Common Mistakes to Avoid
Avoid adding too much marshmallow, as excess can melt and spread too much during baking.
Enhancing Flavor
Using dark cocoa powder or adding a pinch of salt can enhance the chocolate flavor and balance the sweetness.
Serving Ideas and Occasions
