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

Filling

  • 1 cup marshmallow fluff or 12 large marshmallows, cut into pieces

Instructions

  1. Mix dry ingredients: In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt until evenly combined. Set this mixture aside for later.
  2. Cream butter and sugar: In a large mixing bowl, use an electric mixer to cream the unsalted butter and granulated sugar together until light and fluffy, about 3 to 4 minutes. This step incorporates air for 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. Then blend in the vanilla extract for added flavor.
  4. Combine wet and dry: Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed just until combined. Avoid overmixing to keep the cookies tender.
  5. Chill the dough: Cover the dough and refrigerate for at least 1 hour to firm up the dough, making it easier to handle and shape.
  6. Prepare to bake: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats for easy cleanup and even baking.
  7. Shape cookies: Scoop out portions of the chilled dough and roll into balls. Place them on the prepared baking sheets, spacing each about 2 inches apart to allow spreading.
  8. Add marshmallow swirl: Press a small indent into the center of each dough ball. Spoon about a teaspoon of marshmallow fluff or place a marshmallow piece into the indent. Use a toothpick to gently swirl the marshmallow into the surrounding dough for a marbled effect.
  9. Bake cookies: Bake for 10 to 12 minutes, or until the edges are set but the centers remain soft. For extra gooey marshmallow topping, optionally add a bit more fluff on top halfway through baking.
  10. Cool cookies: Let the cookies rest on the baking sheets for 5 minutes after removing from the oven. Then transfer them to a wire rack to cool completely before serving.

Notes

  • For best results, use room temperature eggs and butter to ensure smooth mixing and proper texture.
  • Chilling the dough helps control spreading and makes the cookies easier to handle.
  • You can substitute marshmallow fluff with cut pieces of regular marshmallows, but fluff melts more evenly.
  • Storing cookies in an airtight container keeps them soft and fresh for up to 5 days.
  • For an even richer flavor, consider adding a teaspoon of espresso powder to the dry ingredients.
