Now, let’s dive into what you need to gather for your next batch of these beloved Chocolate Marshmallow Swirl Cookies.

What You’ll Need:

For these Chocolate Marshmallow Swirl Cookies, you’ll want to have the following basics on hand:

  • 1 cup unsalted butter, softened (room temp makes mixing easier)
  • 1 cup granulated sugar – you can swap half with brown sugar for a deeper flavor
  • 2 large eggs
  • 2 teaspoons vanilla extract – find this in the regular spice aisle, so no extra stop needed
  • 2 cups all-purpose flour
  • 1/2 cup unsweetened cocoa powder – this makes the chocolate swirl part rich and homey
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 to 1 1/2 cups mini marshmallows – if you don’t have mini, regular marshmallows can be cut into smaller pieces
Ingredients for Chocolate Marshmallow Swirl Cookies including butter, sugar, eggs, cocoa powder and mini marshmallows

You probably already have most of these at home. I love this recipe because it’s affordable—nothing fancy or exotic. If you want to save time, pre-soften your butter by cutting it into cubes and letting it sit on the counter as you prep other ingredients. If you happen to have leftover marshmallows, store them in an airtight container; they freeze well too.

My secret to taking these Chocolate Marshmallow Swirl Cookies over the top is adding a bit extra vanilla and a pinch more salt than usual. It gives the chocolate that “wow” factor you’d expect in a chocolate dessert cookie without complicating things.

Let’s Cook It Together!

1. Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper or silicone mats for easy cleanup and to prevent sticking. This step sets you up for smooth baking.

2. Cream the butter and sugar. Using a hand mixer or stand mixer, beat softened butter and granulated sugar until creamy and light. This usually takes about 3-4 minutes. It’s worth the wait because a well-creamed base means fluffier cookies.

3. Add eggs and vanilla. Beat in the eggs one at a time, followed by the vanilla extract. Scrape down the bowl if things stick to sides. Your batter should be smooth and glossy here.

4. Mix dry ingredients in another bowl. Whisk together flour, cocoa powder, baking soda, and salt. You’ll want the cocoa evenly mixed so every bite has that chocolate swirl effect.

5. Combine wet and dry. Gradually add the dry mixture to the wet ingredients, mixing until just combined. Don’t overdo it—this can toughen your cookies.

6. Add marshmallows last. Gently fold in your mini marshmallows, being careful not to crush them too much. Those gooey pockets are the stars in these chocolate swirl cookies.

7. Scoop dough onto baking sheets. I use a tablespoon scooper to keep cookies uniform. Keep them about 2 inches apart since they spread a little.

8. Bake for 10 to 12 minutes. Your kitchen will start smelling incredible—the warm chocolate and marshmallow mix will pull everyone near. The cookies might look slightly underbaked on top; that’s perfect for soft, gooey marshmallow cookies.

9. Cool briefly before moving. Let them sit on the baking sheet for 5 minutes, then move to a wire rack. This helps them set just right without losing the softness inside.

From start to finish, this Chocolate Marshmallow Swirl Cookies recipe takes about 40 minutes, and trust me, it’s time well spent. While the first batch bakes, you can tidy up your mix bowls or start brewing a cup of coffee to enjoy with the fresh cookies. If your marshmallows start to melt out too much and spread unevenly, no worries—that’s just part of the charm.

Years of making these cookies have taught me to trust the timing fully: pulling them out too soon makes the dough too raw, and waiting too long dries out their gooey center. This balancing act is part of what makes these chocolate dessert cookies worth sharing.

How to Serve & Enjoy It!

Freshly baked Chocolate Marshmallow Swirl Cookies served on a plate

Chocolate Marshmallow Swirl Cookies are perfect with a cold glass of milk or a warm cup of tea. I usually serve them right out of the oven at family get-togethers, where everyone loves watching the marshmallow swirl stretch between bites. They’re an easy crowd-pleaser for casual parties or simple dessert after dinner.

If you’re thinking of something extra special, pairing these gooey marshmallow cookies with vanilla ice cream or a drizzle of caramel sauce can make the experience feel indulgent without adding much prep.

These chocolate swirl cookies work well for holiday baking too. Around Christmas, consider adding a sprinkling of crushed peppermint on top before baking for a festive touch. For summer cookouts, these cookies are a sweet finish that doesn’t require oven space during the main meal.

Leftover cookies? No problem! Try using them in cookie sandwiches with chocolate frosting or gently warmed to create a s’mores-style dessert. Friends who come by often ask for the recipe because they can’t believe how simple yet delicious these Chocolate Marshmallow Swirl Cookies are.

Your Questions Answered

Can I make Chocolate Marshmallow Swirl Cookies ahead of time? Absolutely. The dough freezes beautifully. Scoop it onto a tray, freeze until firm, then store in a freezer bag. When you’re ready, bake straight from frozen—just add a couple extra minutes to baking time.

What’s the best substitute for cocoa powder in these chocolate dessert cookies? If you’re out, unsweetened baking chocolate can work. Just melt about 2 ounces and reduce the flour slightly. It won’t be a perfect swap but still tasty.

How do I adjust this recipe for more or fewer servings? Simply multiply or divide ingredients proportionally. For smaller batches, I suggest halving the recipe to keep ingredient matches exact.

Can I use large marshmallows instead of mini? Yes, but cut them into smaller cubes first. Mini marshmallows melt evenly, so cubed large ones help get that perfect swirl.

Is there a way to make these cookies less sweet? Try reducing sugar by 1/4 cup and adding a pinch more salt. It balances the sweetness but keeps flavor intact.

Can I substitute butter with margarine or oil? Butter really adds richness, but margarine can work in a pinch. Oil isn’t recommended because it changes the dough texture too much.

How do I store leftover Chocolate Marshmallow Swirl Cookies? Keep them in an airtight container at room temp for up to 4 days. If you want longer, freeze them wrapped tightly in foil or plastic wrap. When you thaw, the marshmallow stays melty and soft.

My Best Chocolate Marshmallow Swirl Cookies Tips:

  • Use room temp butter for better mixing and texture.
  • Don’t overbake—pull them out when just set.
  • Fold marshmallows gently for those irresistible gooey pockets.

I’ve tried variations like adding chopped nuts for crunch, swapping in pumpkin spice for a fall twist, and using cookies and cream marshmallows for fun texture changes. The classic version, though, is the most requested at parties and family dinners.

Feel free to make this recipe your own. Switch up ingredients, try different flavor combos, or even shape the dough for a fun presentation. What matters most is you’ll have something delicious and dependable every time.
