Ingredients
Main Ingredients
– 1 cup all-purpose flour
– 1/2 cup unsweetened cocoa powder
– 1/2 teaspoon baking soda
– 1/4 teaspoon salt
– 1/2 cup unsalted butter, softened
– 1 cup granulated sugar
– 1 large egg

I love using all-purpose flour and unsweetened cocoa powder. They are the base for our cookies. The flour gives the dough structure, while the cocoa adds rich chocolate flavor. Baking soda helps the cookies rise, and salt balances the sweetness.
Softened unsalted butter makes the cookies rich and creamy. Granulated sugar adds sweetness and helps with texture. The large egg binds everything together, giving the cookies a soft center. Vanilla extract adds a subtle warmth to the flavor profile.
The mini marshmallows and chocolate chips are the stars of the show. The marshmallows bring a fun, chewy texture, while the chocolate chips melt into gooey pockets of chocolate bliss.
Optional Ingredients
– Extra cocoa powder for dusting
– Vanilla ice cream for serving
For a fancy touch, I sometimes dust the cookies with extra cocoa powder. It makes them look great! Serving with vanilla ice cream is a treat. The cold ice cream pairs perfectly with the warm cookies.

Step-by-Step Instructions
Prepping the Oven and Baking Sheet
First, you need to preheat the oven to 350°F (175°C). This step is key for even baking. While the oven warms up, take a baking sheet and line it with parchment paper. This will help your cookies not stick.
Mixing the Dry Ingredients
In a mixing bowl, combine these dry ingredients:
– 1 cup all-purpose flour
– 1/2 cup unsweetened cocoa powder
– 1/2 teaspoon baking soda
– 1/4 teaspoon salt
Whisk them together. This helps mix the flavors and makes sure the baking soda is evenly spread.
Preparing the Dough
Now, it’s time to make the cookie dough. In a large bowl, cream together:
– 1/2 cup unsalted butter, softened
– 1 cup granulated sugar
Mix until it looks light and fluffy. Then, add in:
– 1 large egg
– 1 teaspoon vanilla extract
Beat these in until fully mixed. Next, gradually add the dry ingredients to this wet mixture. Mix on low speed until combined.
Gently fold in:
– 1/2 cup mini marshmallows
– 1/2 cup chocolate chips
Use a spatula for this step. Be careful not to break the marshmallows.
Forming the Cookies
Using a tablespoon, scoop out portions of your dough. Place them on the prepared baking sheet, leaving 2 inches between each cookie. To create the swirl effect, use the back of a spoon or your fingers. Just swirl the tops gently.
Baking the Cookies
Bake your cookies in the preheated oven for 10-12 minutes. You want the edges to set but the centers to stay soft. After baking, let them cool on the baking sheet for 5 minutes. Then, transfer the cookies to a wire rack to cool completely. Enjoy the delightful aroma wafting through your kitchen!
Tips & Tricks
Baking Tips
– Achieving the perfect texture: To get soft and chewy cookies, do not overmix your dough. Mix just until combined. This keeps the cookies tender.
– Ensuring even baking: Space your cookie dough balls about 2 inches apart on the baking sheet. This allows the heat to circulate. It helps cookies bake evenly.
Serving Suggestions
– Decorative presentation: Arrange cookies on a nice plate. Dust with extra cocoa powder. This adds a touch of elegance and makes them look fancy.
– Pairing with ice cream: Serve these cookies warm with a scoop of vanilla ice cream. The warm cookie and cold ice cream create a delightful contrast.
Common Mistakes to Avoid
– Overmixing the dough: Mixing too much makes cookies tough. Stop mixing once the ingredients are just combined.
– Not preheating the oven: Always preheat your oven to 350°F. This helps cookies bake properly and gives them a nice rise.
Pro Tips
- Chill the Dough: Chilling the cookie dough for at least 30 minutes can help prevent spreading and result in thicker cookies.
- Fresh Ingredients: Ensure that your baking soda and cocoa powder are fresh for the best flavor and texture in your cookies.
- Swirling Technique: For a more dramatic marbled effect, use a toothpick or skewer to create deeper swirls in the cookie dough.
- Storage Tips: Store cookies in an airtight container at room temperature for up to a week, or freeze them for longer storage.
Variations
Flavor Swaps
You can change the flavor of your cookies easily. One fun swap is using white chocolate chips instead of regular chocolate chips. This swap adds a sweet, creamy taste that contrasts well with the cocoa. You can also add nuts like walnuts or pecans. They give a nice crunch and extra flavor. Just chop them up and fold them into the dough before baking.
Dietary Adjustments
If you need gluten-free cookies, try using gluten-free flour. Many blends work well, so choose one that you like. This swap keeps your cookies tasty and safe for those with gluten sensitivities. For a vegan option, replace the butter with coconut oil. Also, use a flax egg instead of a regular egg. Mix one tablespoon of ground flaxseed with three tablespoons of water. Let it sit for a few minutes to thicken.
Theme Variations
Make your cookies special for the holidays! Add festive sprinkles on top before baking. This adds color and fun to your treats. You can also use seasonal ingredients. For fall, add pumpkin spice to the dough. In summer, try mixing in fresh berries. These additions keep your cookies exciting all year round!
Storage Info
Short-term Storage
To store your cookies at room temperature, use an airtight container. Place parchment paper between layers of cookies. This keeps them fresh and soft for about 3 to 5 days. If you want to keep them even longer, consider adding a piece of bread to the container. The bread helps absorb moisture and keeps cookies from drying out.
Long-term Storage
For long-term storage, freezing is the best option. Start by letting the cookies cool completely. Then, stack them in a single layer on a baking sheet. Freeze for 1 to 2 hours until firm. After that, transfer them to a freezer-safe bag or container. They can last up to 3 months in the freezer. Remember to label the bag with the date. This way, you know when to enjoy them!
Reheating Instructions
When you want to enjoy frozen cookies, reheating is easy. Preheat your oven to 350°F (175°C). Place the cookies on a baking sheet. Heat them for about 5 to 10 minutes. This method keeps the texture soft and chewy. Avoid using the microwave, as it can make the cookies tough. For best results, let them cool slightly before eating. Enjoy your delicious cookies!
FAQs
How can I make Chocolate Marshmallow Swirl Cookies ahead of time?
You can prepare the dough ahead of time. After mixing the dough, wrap it tightly in plastic wrap. Store it in the fridge for up to two days. You can also freeze the dough. Just scoop the dough onto a baking sheet and freeze until firm. Once firm, transfer the cookie dough balls to a freezer bag. They’ll last up to three months. When ready to bake, just pop them in the oven straight from the freezer. You may need to add a minute or two to the baking time.
What can I use instead of mini marshmallows?
If you do not have mini marshmallows, you can use chopped large marshmallows. This will work great and still give you that gooey texture. Another option is using marshmallow fluff. Just swirl it in gently after you shape the cookies. If you want a fun twist, try using caramel bits or chocolate-covered marshmallows. These will change the flavor but keep it delicious.
Can I use different types of chocolate?
Yes, you can use various kinds of chocolate in your cookies. Dark chocolate chips will give a richer flavor. Milk chocolate is sweeter and creamier. For a fun twist, you could try white chocolate chips. You can even mix different types! Just make sure to keep the total amount of chocolate the same. This will help keep the cookie’s texture just right.
