Ingredients You’ll Need

These ingredients might seem simple, but each one plays a crucial role in building the perfect cookie. From the basic structure provided by the flour to the sweet bursts from marshmallows and chocolate chips, every component contributes to the cookie’s irresistible flavor and texture.

• 1 ¾ cups (220 g) all-purpose flour: Provides the sturdy base and perfect crumb for the cookies.
• 1/2 cup (40 g) unsweetened cocoa powder: Delivers that rich, deep chocolate flavor that cookie lovers crave.
• 1 teaspoon baking soda: Gives the cookies a light, tender rise without overpowering the texture.
• 1/4 teaspoon salt: Enhances all the sweet and chocolatey notes to balance every bite.
• 1/2 cup (115 g) unsalted butter, softened: Adds a creamy richness and helps achieve that melt-in-your-mouth softness.
• 3/4 cup (150 g) granulated sugar: Introduces sweetness with a slight crunch that you’ll love.
• 1/2 cup (100 g) packed light brown sugar: Brings chewiness and hints of caramel with its molasses content.
• 1 large egg: Binds everything together for consistent texture and structure.
• 1 teaspoon vanilla extract: Infuses warmth and depth, lifting the entire mix.
• 1/2 cup (90 g) semi-sweet chocolate chips: For those pockets of extra chocolate joy in every bite.
• 1 cup (50 g) mini marshmallows: The star ingredient that creates the irresistibly gooey swirls.
• 1/3 cup (60 g) marshmallow fluff (optional): Enhances the swirl effect with extra creaminess and stretch.

How to Make Chocolate Marshmallow Swirl Cookies Recipe

Step 1: Prep the Oven and Ingredients

Start off by heating your oven to 350°F (175°C). Line your baking sheets with parchment paper or silicone mats to prevent sticking and make cleanup a breeze. Organize all ingredients ahead of time to keep your process smooth and stress-free.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. This step makes sure the cocoa is perfectly blended and lumps are avoided, resulting in an even chocolate flavor throughout your cookies.

Step 3: Cream the Butter and Sugars

Using your mixer, cream the softened butter with both sugars until the mixture becomes light, fluffy, and pale—around 2 to 3 minutes. This crucial step infuses air into the dough, promising tender, soft cookies with a slight crunch.

Step 4: Add the Wet Ingredients

Beat in the egg and vanilla extract until fully incorporated. Keep the bowl scraped down so no pockets of dry or wet ingredients remain separate; this ensures a smooth, balanced dough.

Step 5: Combine Wet and Dry

Slowly add the dry ingredients to the wet mix in two or three batches, mixing just until combined each time. Overmixing can develop gluten and make the cookies tough, so use a gentle hand here.

Step 6: Fold in the Chocolate Chips

Gently fold in the semi-sweet chocolate chips, spreading those melty, chocolate surprises throughout the dough. This adds bursts of classic chocolate charm to each cookie.

Step 7: Add the Marshmallow Swirl

Now comes the magic: carefully fold in the mini marshmallows along with dollops of marshmallow fluff if you’re using it. Be delicate so you keep those gorgeous marshmallow streaks visible — this is what makes the Chocolate Marshmallow Swirl Cookies Recipe so special.

Step 8: Scoop and Bake

Use a cookie scoop or tablespoon to portion the dough onto your baking sheets, spacing them about 2 inches apart. Bake for 8-10 minutes until the edges are firm but the centers still feel slightly soft. Keep an eye on the marshmallows—they may melt and caramelize just a bit, adding a toasty, golden flavor that’s seriously addictive.

Step 9: Cool and Enjoy

Let the cookies cool right on the baking sheet for 5 minutes before transferring them to a wire rack. This resting time lets them set up perfectly without crumbling, giving you cookies that hold their shape but stay wonderfully tender.

How to Serve Chocolate Marshmallow Swirl Cookies Recipe

Garnishes

Elevate your cookie presentation by dusting a little powdered sugar on top or adding a drizzle of melted chocolate or caramel right before serving. Edible gold flakes or chopped toasted nuts can add an extra touch of elegance and texture for special occasions.

Side Dishes

These cookies pair wonderfully with a tall glass of cold milk—classic and irresistible—or a warm cup of coffee or hot cocoa to complement the marshmallow’s sweetness. For an adult twist, try them alongside a creamy Bailey’s or coffee liqueur-based drink for a cozy after-dinner treat.

Creative Ways to Present

For gift-giving or parties, arrange these cookies on a festive platter with a few chocolate chunks and marshmallows scattered decoratively around. You can even sandwich two cookies together with marshmallow fluff or chocolate ganache for a playful twist, making them look as impressive as they taste.

Make Ahead and Storage

Storing Leftovers

Keep your leftover Chocolate Marshmallow Swirl Cookies Recipe fresh by storing them in an airtight container at room temperature for up to 4 days. Layering the cookies between sheets of parchment paper prevents sticking, especially with all that gooey marshmallow goodness inside.

Freezing

If you want to save some for later, these cookies freeze beautifully. Place them in a single layer on a baking sheet, freeze until solid, then transfer to a freezer-safe container or bag. They’ll keep well for up to 3 months and thaw quickly to that perfect chewy texture.

Reheating

To revive their fresh-baked warmth, pop the cookies in a preheated oven at 300°F (150°C) for 5-7 minutes or microwave them for about 15 seconds. This melts the marshmallow slightly again, bringing back that irresistible swirl and softness.

FAQs

Can I use regular marshmallows instead of mini ones?

Absolutely! Just chop regular marshmallows into smaller pieces to ensure even distribution and that lovely swirl effect you want in the Chocolate Marshmallow Swirl Cookies Recipe.

Is the marshmallow fluff necessary?

Marshmallow fluff is optional but highly recommended if you want a more prominent swirl and extra creaminess. Without it, you’ll still get delicious cookies with gooey mini marshmallows throughout.

Can I substitute the cocoa powder with baking chocolate?

You could, but cocoa powder keeps the cookies tender while imparting a rich flavor. Baking chocolate would require melting and adjusting other ingredients, so it’s best to stick with cocoa powder for this recipe.

How do I prevent marshmallows from melting too much?

Folding them in gently and baking for the recommended time helps. The marshmallows will soften and melt slightly, which is exactly what creates the swirl effect; just avoid overbaking to keep some texture.

Are these cookies gluten-free?

The recipe as is uses all-purpose flour, which contains gluten. To make a gluten-free version, try swaping with a suitable gluten-free baking flour blend, but results may vary in texture.

There’s just something so heartwarming about baking up a batch of the Chocolate Marshmallow Swirl Cookies Recipe.
