Ingredients
- 2 cups all-purpose flour
- ¾ cup unsweetened cocoa powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- 1 cup unsalted butter, room temperature
- 1½ cups granulated sugar
- 2 large eggs, room temperature
- 2 teaspoons vanilla extract
- 1 cup marshmallow fluff
Instructions
- Step 1: In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set aside.
- Step 2: In a large bowl, cream the butter and sugar with an electric mixer until light and fluffy, about 3-4 minutes.
- Step 3: Beat in the eggs one at a time, fully incorporating each before adding the next. Stir in the vanilla extract.
- Step 4: Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined. Avoid overmixing.
- Step 5: Cover the dough and refrigerate for at least 1 hour to make it easier to handle and reduce spreading during baking.
- Step 6: Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats.
- Step 7: Scoop or roll chilled dough into balls and place them on the baking sheets about 2 inches apart.
- Step 8: Press a small indent in the center of each dough ball and spoon about a teaspoon of marshmallow fluff into it. Swirl gently with a toothpick.
- Step 9: Bake for 10-12 minutes until edges are set but centers remain soft. Optionally, add more fluff halfway through baking for extra gooeyness.
- Step 10: Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Tips & Variations
- Chill the dough for at least an hour to prevent excessive spreading and make shaping easier.
- Use a cookie scoop for uniform cookie sizes and even baking.
- Bake at a slightly lower temperature (325°F) if you want softer cookies with marshmallow swirls that don’t burn.
- Add the marshmallow fluff halfway through baking to keep swirls visible and gooey.
- For a vegan version, substitute vegan marshmallows, plant-based butter, and dairy-free chocolate chips.
- Try adding chopped walnuts or pecans for extra texture and flavor.
- Mix in cinnamon or cayenne pepper for a subtle spicy warmth.
- Experiment with white or dark chocolate chips for added chocolate complexity.
Storage
Store cookies in an airtight container at room temperature for up to 5 days, layering with parchment paper to prevent sticking. You can freeze baked cookies for up to 3 months once cooled completely. To reheat, warm cookies in a microwave for 10-15 seconds or in an oven preheated to 300°F (150°C) for 5-10 minutes to refresh their texture.

FAQs
Can I use marshmallows instead of marshmallow fluff?

How do I prevent the cookies from spreading too much?
Make sure to chill the dough thoroughly before baking and avoid overcrowding the baking sheet to ensure even baking and proper shape retention.

Ingredients
Dry Ingredients
- 2 cups all-purpose flour
- ¾ cup unsweetened cocoa powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
Wet Ingredients
- 1 cup unsalted butter, room temperature
- 1½ cups granulated sugar
- 2 large eggs, room temperature
- 2 teaspoons vanilla extract
- 1 cup marshmallow fluff
Instructions
- Mix Dry Ingredients: In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt until well combined. Set aside.
- Cream Butter and Sugar: Using an electric mixer, beat the unsalted butter and granulated sugar together until light and fluffy, about 3 to 4 minutes. This aerates the mixture, contributing to a tender cookie texture.
- Add Eggs and Vanilla: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract to evenly distribute flavor.
- Combine Wet and Dry Ingredients: Gradually add the dry mixture to the wet ingredients while mixing on low speed just until a dough forms. Avoid overmixing to prevent tough cookies. You may swirl in some marshmallow fluff now for a subtle incorporation or wait until after the dough is chilled.
- Chill the Dough: Cover the dough and refrigerate for at least 1 hour. Chilling firms the dough, making it easier to handle and preventing cookies from spreading excessively during baking.
- Preheat Oven and Prepare Baking Sheets: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats to prevent sticking.
- Form Cookies and Add Marshmallow Swirls: Using a cookie scoop or tablespoon, portion out the chilled dough into balls and place them about 2 inches apart on the sheets. Press a small indent into the center of each ball, spoon about 1 teaspoon of marshmallow fluff into the indentation, and use a toothpick to gently swirl the marshmallow into the cookie dough.
- Bake: Bake for 10-12 minutes or until edges are set but centers remain soft. For extra gooey swirls, optionally add a small amount of marshmallow fluff on top halfway through baking.
- Cool on Pan: Allow cookies to cool on the baking sheet for 5 minutes to let the marshmallow set slightly before transferring to a wire rack to cool completely. This prevents breakage and ensures the perfect texture.
Notes
- Chill dough for at least 1 hour to prevent spreading.
- Use a cookie scoop for uniform cookie size and even baking.
- Line baking sheets with parchment or silicone mats to prevent sticking, especially from marshmallow.

- Cool cookies on baking sheet before moving to wire rack to help marshmallow set.
