Chocolate Marshmallow Swirl Cookies

These chocolate marshmallow swirl cookies bring together the richness of cocoa and the playful sweetness of marshmallow in every bite. Perfectly soft with just a hint of chewiness, they are an irresistible treat when you want something homemade and satisfying.

I first made these to recreate the feeling of campfire s’mores and they quickly became a favorite for cozy weekends at home.

Ingredients You Need

• All-purpose flour: provides structure to hold the cookie together, choose unbleached for best results
• Unsweetened cocoa powder: gives the deep chocolate taste, fresh and dark cocoa is ideal
• Granulated sugar: sweetens and helps create a tender crumb
• Baking soda: acts as a gentle leavening agent, helping the cookies spread just right
• Salt: balances the sweetness and enhances flavors
• Unsalted butter at room temperature: offers richness and softness, make sure it is not melted
• Large egg: binds ingredients and contributes to moisture
• Vanilla extract: adds subtle warmth and depth to the dough
• Semi-sweet chocolate chips: create pockets of intensified chocolate flavor, opt for quality chips that melt smoothly
• Mini marshmallows: give that signature gooey swirl and delicate chew, fresh marshmallows work best

Detailed Cooking Directions

Build The Oven Ready Setup:

Preheat your oven to 350 degrees Fahrenheit or 175 degrees Celsius and line two baking sheets with parchment paper to prevent sticking and promote even baking

Mix Dry Ingredients:

In a medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt to evenly distribute the leavening and seasoning

Cream Butter and Sugar:

In a separate large bowl, beat the softened unsalted butter and granulated sugar until the mixture becomes light in color and fluffy in texture, building a creamy base for the dough

Incorporate Wet Ingredients:

Add the large egg and vanilla extract to the butter and sugar mixture and continue mixing until everything is fully blended and smooth

Combine Dry and Wet Mixtures:

Gradually add the dry ingredients to the wet mixture, stirring just until they come together into a uniform dough, careful not to overmix which can toughen the cookies

Add Chocolate Chips and Marshmallows:

Gently fold the semi-sweet chocolate chips and mini marshmallows into the dough, ensuring they are evenly spread but keeping their shape intact

Shape and Bake:

Drop spoonfuls of dough onto the parchment-lined baking sheets, spacing them apart to allow spreading. Bake in the preheated oven for 10 to 12 minutes or until the edges are set but the centers remain soft

Let The Cookies Cool:

Allow the cookies to cool on the baking sheets for a few minutes before transferring them to a wire rack to finish cooling, this helps them firm up without losing their chewy texture

Smart Storage Tips

Smart Storage Tips

Keep cookies in an airtight container at room temperature to preserve softness for up to three days. For longer storage, freeze in a single layer on a baking sheet and then transfer to a resealable bag, thaw at room temperature before enjoying. If they lose a bit of softness, a few seconds in the microwave will bring back that fresh-baked feel.

Ingredient Variations

Try using dark chocolate chips or chunks to intensify the chocolate flavor for a richer bite. Swap mini marshmallows for flavored ones like strawberry or caramel for an interesting twist. Add a sprinkle of sea salt on top before baking to balance the sweetness and add texture.

Perfect Pairing Ideas

A cold glass of milk or a creamy vanilla latte enhances the chocolatey, sweet flavors perfectly. Serve alongside fresh berries or a scoop of vanilla ice cream for a dessert upgrade. A small cup of hot cocoa complements the marshmallow goodness and makes it a cozy winter treat.

These chocolate marshmallow swirl cookies never fail to bring smiles and comfort whether baked for a quiet afternoon or a lively get-together. Their simplicity hides the joy they deliver with every gooey, chocolatey bite.

Frequently Asked Questions

→ How can I make the cookies softer?

Underbaking slightly helps keep the cookies soft and chewy. Remove them from the oven when edges look set but centers are still a bit soft.

→ Can I substitute the marshmallows?

Mini marshmallows work best for even melting and swirl effect, but standard size chopped finely or flavored variations can add a new twist.

→ What chocolate chips work best here?

Semi-sweet chocolate chips provide a good balance with the cocoa dough and marshmallows, but milk or dark chocolate chips can be used depending on your preference.

→ Should I chill the dough before baking?

Chilling isn’t necessary, but it can help control spreading and enhance flavors if you have extra time.

→ How should I store these cookies?

Keep them in an airtight container at room temperature to maintain freshness and softness for several days.
