Ingredients You’ll Need
Here’s what you’ll need to whip up these cookies. The recipe makes about 18 cookies, depending on size.
Dry Ingredients:
- 1 ¾ cups (220 g) all-purpose flour: Provides the structure of the cookie.
- 1/2 cup (40 g) unsweetened cocoa powder: For that rich chocolate flavor.
- 1 teaspoon baking soda: Helps the cookies rise.
- 1/4 teaspoon salt: Enhances the flavors.
Wet Ingredients:
- 1/2 cup (115 g) unsalted butter, softened: Adds richness and flavor.
- 3/4 cup (150 g) granulated sugar: Sweetness with a slight crunch.
- 1/2 cup (100 g) packed light brown sugar: Adds chewiness and a hint of molasses flavor.
- 1 large egg: Binds the ingredients together.
- 1 teaspoon vanilla extract: Brings warmth and depth.
Mix-Ins:
- 1/2 cup (90 g) semi-sweet chocolate chips: For extra chocolatey pockets.
- 1 cup (50 g) mini marshmallows: The gooey, star ingredient.
- 1/3 cup (60 g) marshmallow fluff (optional): Enhances the swirl effect.
Special Equipment
- Large mixing bowl and hand mixer: To cream the butter and sugars.
- Baking sheets and parchment paper: Ensures even baking and easy cleanup.
- Cookie scoop: For evenly sized cookies.
- Cooling rack: To cool the cookies without overcooking them on the hot pan.
Step-by-Step Instructions
Let’s break it down into simple, manageable steps:
1. Prep the Oven and Ingredients
Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats to prevent sticking. Measure out all your ingredients to streamline the process.
2. Mix the Dry Ingredients
In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. This ensures the cocoa is evenly distributed, and there are no lumps.
3. Cream the Butter and Sugars
In a large mixing bowl, use a hand or stand mixer to cream the softened butter, granulated sugar, and brown sugar together until light and fluffy (about 2-3 minutes). The mixture should turn pale and airy—this step is essential for a tender cookie.
4. Add the Wet Ingredients
Beat in the egg and vanilla extract, mixing until fully incorporated. Scrape down the sides of the bowl to ensure everything is well combined.
5. Combine Wet and Dry
Gradually add the dry ingredients to the wet ingredients in 2-3 additions. Mix on low speed until just combined. Avoid overmixing, as this can lead to tough cookies.
6. Fold in the Chocolate Chips
Gently fold in the semi-sweet chocolate chips for bursts of melty goodness in every bite.
7. Add the Marshmallow Swirl
This step is where the magic happens. Add the mini marshmallows and dollops of marshmallow fluff (if using) into the dough. Use a spatula to fold them in, being careful not to overmix. You want to see streaks of marshmallow throughout the dough for that swirl effect.
8. Scoop and Bake
Using a cookie scoop or tablespoon, scoop the dough onto the prepared baking sheets, leaving about 2 inches between each cookie. Bake for 8-10 minutes, or until the edges are set but the centers are still slightly soft.
Tip: Keep an eye on the marshmallows during baking—they may ooze and caramelize slightly, which adds a delightful toasty flavor.
9. Cool and Enjoy
Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack. This allows the cookies to firm up slightly and prevents breakage.
Variations and Substitutions
- Double Chocolate Madness: Swap semi-sweet chocolate chips for dark chocolate chunks and add a handful of white chocolate chips for a triple chocolate treat.
- Nutty Twist: Fold in 1/2 cup of chopped toasted pecans or walnuts for a crunchy contrast.
- Peppermint Swirl: Add 1/2 teaspoon of peppermint extract and top with crushed candy canes for a festive holiday version.
- Gluten-Free Option: Use a 1:1 gluten-free baking flour instead of all-purpose flour.
Storage and Freezing
- At Room Temperature: Store the cookies in an airtight container for up to 5 days. Adding a slice of bread to the container helps keep the cookies soft.
- In the Freezer: Freeze unbaked cookie dough balls on a baking sheet, then transfer them to a freezer bag. Bake directly from frozen, adding 1-2 minutes to the baking time.
- Reheating Tip: Warm the cookies in the microwave for 10 seconds to revive their gooey texture.

Tips for Perfect Cookies
- Don’t Overbake: The cookies will continue to cook slightly as they cool. Take them out when the centers are just set.
- Marshmallow Management: Marshmallows can ooze during baking, so don’t place them too close to the edges of the cookie dough balls.
- Chill the Dough (Optional): For thicker cookies, refrigerate the dough for 30 minutes before baking.
Beverage Pairings
- Hot Chocolate: Double down on the chocolatey goodness.
- Milk (Classic or Plant-Based): A glass of cold milk complements the rich flavors perfectly.
- Coffee or Espresso: The slight bitterness of coffee balances the sweetness.
