Ingredients

Scale

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

  1. Mix Dry Ingredients: In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt until well combined. Set aside.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  • Add marshmallow fluff halfway through baking or swirl into dough after chilling to preserve visible gooey swirls.
  • Cool cookies on baking sheet before moving to wire rack to help marshmallow set.
  • For vegan or gluten-free versions, substitute ingredients as advised in the recipe variations.
  • Store cookies in an airtight container at room temperature for up to 5 days or freeze for 3 months.
