Ingredients

Scale

Dry Ingredients

  • 2 cups all-purpose flour
  • 3/4 cup unsweetened cocoa powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt

Wet Ingredients

  • 1 cup unsalted butter, room temperature
  • 1 1/2 cups granulated sugar
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract

Additional

  • 1 cup marshmallow fluff

Instructions

  1. Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt until fully combined. Set this mixture aside for later incorporation into the wet ingredients.
  2. Cream Butter and Sugar: Using an electric mixer in a large bowl, beat the room temperature unsalted butter with the granulated sugar until the mixture is light and fluffy, which will take about 3 to 4 minutes. This step is key for the cookie’s texture.
  3. Add Eggs and Vanilla: Beat in the eggs one at a time, ensuring each egg is fully mixed in before adding the next. Then stir in the vanilla extract to infuse the dough with a warm, aromatic flavor.
  4. Combine Wet and Dry Ingredients: Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed just until the dough comes together. Avoid overmixing to keep the cookies tender. You can gently swirl in some marshmallow fluff now or wait until after chilling.
  5. Chill the Dough: Cover the dough and refrigerate it for at least 1 hour. This step firms up the dough, making it easier to handle and helps prevent the cookies from spreading too much during baking.
  6. Preheat Oven and Prepare Baking Sheets: About 20 minutes before baking, preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats to prevent sticking.
  7. Form Cookies: Scoop out chilled dough using a cookie scoop or tablespoon and roll into balls. Place them on the prepared baking sheets about 2 inches apart. Press a small indent in the center of each dough ball and spoon about a teaspoon of marshmallow fluff into the indent. Use a toothpick to swirl the marshmallow into the cookie dough for a decorative and flavorful swirl.
  8. Bake: Bake the cookies in the preheated oven for 10-12 minutes, until the edges are set but centers remain soft. Optionally, add a bit more marshmallow fluff on top halfway through baking for extra gooeyness.
  9. Cool on Pan: Let the cookies cool on the baking sheets for about 5 minutes. This resting time helps the marshmallow swirl to set slightly and makes the cookies easier to transfer. Then move them to a wire rack to cool completely before serving.

Notes

  • If the dough feels sticky, chill it for 30 minutes before shaping to make handling easier.
  • Using real marshmallows instead of marshmallow fluff results in a fluffier, less melted swirl.
  • For a different texture, place one jumbo marshmallow in the center of each cookie instead of swirling fluff.
  • Rotate baking sheets halfway through baking to ensure even cooking and browning.
  • Store baked cookies in an airtight container at room temperature to keep them fresh.
  • You can freeze shaped dough balls for future baking; just extend baking time by a couple of minutes when baking from frozen.
