4.8 from 149 reviews

These Chocolate Marshmallow Swirl Cookies are rich, fudgy, and perfectly sweet with a gooey marshmallow center swirled into each cookie. Combining deep cocoa flavor with soft marshmallow fluff, they make a delightful treat for any chocolate lover. The cookies are baked to have slightly crisp edges while remaining soft and chewy inside, enhanced by the melt-in-your-mouth marshmallow swirl.

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

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 evenly combined. Set this mixture aside for later.
  2. Cream Butter and Sugar: Using an electric mixer, beat the room temperature unsalted butter and granulated sugar in a large bowl until the mixture is light and fluffy; this should take about 3 to 4 minutes.
  3. Add Eggs and Vanilla: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Then stir in the vanilla extract for flavor.
  4. Combine Wet and Dry Ingredients: Gradually add the dry mixture to the wet mixture on low speed, mixing just until the dough comes together. Avoid overmixing to keep your cookies tender.
  5. Chill the Dough: Cover the dough and refrigerate it for at least 1 hour. This helps firm up the dough, making it easier to handle and preventing excessive spreading during baking.
  6. Preheat the Oven and Prepare Baking Sheets: About 20 minutes before baking, preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats.
  7. Form Cookies: Scoop the chilled dough into balls using a cookie scoop or tablespoon and place them spaced 2 inches apart on the prepared sheets. Press a small indent into the center of each dough ball, spoon a teaspoon of marshmallow fluff into each indent, then use a toothpick to gently swirl the marshmallow into the cookie dough.
  8. Bake: Bake the cookies for 10 to 12 minutes, or until the edges are set but the centers remain soft. For extra gooeyness, you may add a bit more marshmallow fluff on top halfway through the baking time.
  9. Cool on Pan: Allow the cookies to cool on the baking sheet for 5 minutes to let the marshmallow set slightly. Then transfer the cookies to a wire rack to cool completely before serving.

Notes

  • Chilling the dough is essential to prevent the cookies from spreading too much while baking.
  • Room temperature ingredients ensure even mixing and optimal texture.
  • For an extra chocolate hit, sprinkle a few chocolate chips on top before baking.
  • Store cookies in an airtight container at room temperature for up to 5 days.
  • These cookies can also be frozen before baking; just thaw and bake as directed.
