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 all-purpose flour, unsweetened cocoa powder, baking soda, and salt until thoroughly combined. Set this mixture aside.
  2. Cream Butter and Sugar: Using an electric mixer, beat the room temperature unsalted butter with granulated sugar in a large bowl until the mixture is light and fluffy, which usually takes about 3 to 4 minutes.
  3. Add Eggs and Vanilla: Beat in the large eggs one at a time, ensuring each egg is fully incorporated before adding the next. Stir in the vanilla extract for flavor.
  4. Combine Wet and Dry: Gradually add the dry ingredients to the wet mixture, mixing on a low speed until the dough just comes together. Be careful not to overmix. You can swirl in some marshmallow fluff now or reserve it for later.
  5. Chill the Dough: Cover the dough and refrigerate it for at least 1 hour. Chilling helps the dough firm up, making it easier to shape and prevents the cookies from spreading too much during baking.
  6. Preheat Oven: About 20 minutes before baking, preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats.
  7. Form Cookies: Scoop out dough using a cookie scoop or tablespoon and roll into balls. Place the dough balls on the prepared baking sheets, spacing them approximately 2 inches apart. Press an indent in the center of each ball and spoon about a teaspoon of marshmallow fluff into the indent. Use a toothpick to swirl the fluff into the cookie dough gently.
  8. Bake: Bake the cookies in the preheated oven for 10 to 12 minutes until the edges are set but the centers remain soft. For extra gooeyness, optionally add a little more marshmallow fluff on top halfway through baking.
  9. Cool on Pan: Let the cookies cool on the baking sheet for 5 minutes to allow the marshmallow to set slightly, then transfer them to a wire rack to cool completely for best texture.

Notes

  • Ensure eggs and butter are at room temperature to achieve a smooth dough consistency.
  • Do not overmix the dough once combining wet and dry ingredients to keep cookies tender.
  • Chilling the dough is essential to prevent excessive spreading while baking.
  • Use parchment paper or silicone mats to avoid sticking and ease cleanup.
  • Swirling the marshmallow fluff just before baking creates a beautiful marbled effect and gooey texture.
  • Store cookies in an airtight container to keep them soft for longer.
