Chocolate Marshmallow Swirl Cookies are so flavorful and surprisingly easy to make even when time feels limited.

I decided to share this recipe because it delivers soft chocolate cookies with a gooey marshmallow center while requiring very little prep and the results feel special enough for any occasion.

Ingredients

Here’s what I use for this recipe and how each ingredient supports the final texture and flavor.

All purpose flour: Builds the structure and keeps the cookies soft but stable.
Cocoa powder: Gives the cookies a deep chocolate base.
Baking soda: Helps the cookies spread and crack slightly on top.
Salt: Balances sweetness and enhances the chocolate flavor.
Butter: Adds richness and creates a tender crumb.
Brown sugar: Contributes moisture and a subtle caramel note.
Granulated sugar: Helps with spreading and sweetness.
Eggs: Bind the dough and provide structure.
Vanilla extract: Rounds out the chocolate flavor.
Marshmallows: Create the signature gooey swirl inside the cookies.

Tools You’ll Need

Mixing bowls: Used to combine wet and dry ingredients evenly.
Whisk: Helps blend dry ingredients thoroughly.
Electric mixer: Creams butter and sugar for the right texture.
Measuring cups and spoons: Ensure consistent results.
Baking sheet: Holds cookies during baking.
Parchment paper: Prevents sticking and encourages even baking.
Cooling rack: Allows cookies to cool properly without sogginess.

Instructions

Step 1 Mix the Dry Ingredients

I start by whisking together the flour cocoa powder baking soda and salt. I make sure everything is evenly mixed so each cookie bakes consistently.

Step 2 Cream Butter and Sugars

I beat the butter brown sugar and granulated sugar until light and fluffy. This step is key for soft cookies with crisp edges.

Step 3 Add Eggs and Vanilla

I mix in the eggs one at a time followed by the vanilla extract. I scrape down the bowl to make sure everything blends evenly.

Step 4 Combine Wet and Dry Mixtures

I slowly add the dry ingredients into the wet mixture. I mix just until combined because overmixing can make the cookies tough.

Step 5 Fill with Marshmallows

I scoop portions of dough flatten them slightly and place a marshmallow in the center. I wrap the dough around the marshmallow to seal it completely.

Step 6 Bake the Cookies

I place the dough balls on a lined baking sheet leaving space between them. I bake until the edges are set and the tops crack slightly.

Step 7 Cool and Swirl

I let the cookies cool briefly on the baking sheet before transferring them to a rack. As they cool the marshmallow creates a visible swirl inside.

Tips

From my experience sealing the marshmallow completely inside the dough prevents leaks during baking. I also recommend slightly underbaking the cookies to keep the centers soft and gooey. If marshmallows begin to melt out I gently reshape the cookies while they are still warm.

Ways to Serve

I love serving these cookies warm when the marshmallow center is still stretchy. They work perfectly as a dessert with coffee or milk and are great for parties bake sales or cozy nights at home. I sometimes stack them on parchment paper for a casual presentation that shows off the chocolate cracks.

Storage Instructions

I store Chocolate Marshmallow Swirl Cookies in an airtight container at room temperature for up to three days. To keep them longer I freeze the baked cookies and reheat briefly in the microwave to restore the soft marshmallow center.
