Ingredients

Scale

Chocolate Cookie Base:

  • 1 ¾ cups All-purpose flour
  • ½ cup Unsweetened cocoa powder
  • 1 teaspoon Baking soda
  • ½ teaspoon Salt
  • 1 cup Butter – Softened
  • ¾ cup Brown sugar – Packed
  • ½ cup Granulated sugar
  • 2 Large eggs – Room temperature
  • 1 teaspoon Vanilla extract
  • 1 cup Mini chocolate chips – Optional

Marshmallow Swirl:

  • 1 ½ cups Mini marshmallows – Lightly dusted with powdered sugar
  • ¼ cup Marshmallow fluff – Add a dollop on top of each cookie
  • 1 tablespoon Powdered sugar – For dusting mini marshmallows

Instructions

  1. Preheat and Prep: Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper. Let the butter and eggs sit at room temperature for about 15 minutes to ensure even mixing.
  2. Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt until fully combined and uniform in texture.
  3. Cream Butter and Sugars: In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar until the mixture becomes light and fluffy, indicating proper aeration.
  4. Add Eggs and Vanilla: Incorporate the room temperature eggs and vanilla extract into the creamed butter and sugars, mixing well to blend fully.
  5. Combine Wet and Dry Ingredients: Gradually add the dry ingredient mixture into the wet mixture, stirring gently until just combined. Avoid over-mixing to keep cookies tender. Fold in the mini chocolate chips if using.
  6. Form Cookies with Marshmallow Swirl: Scoop dough into balls and place them on the prepared baking sheets, spaced about 2 inches apart. Press 4 to 5 mini marshmallows into the center of each dough ball, then add a small dollop of marshmallow fluff on top. Use a toothpick to gently swirl the marshmallow fluff into the marshmallows, creating a marbled effect.
  7. Bake: Place the cookies in the preheated oven and bake for 10 to 12 minutes, or until the edges are set but the centers remain soft.
  8. Cool and Serve: Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • Nutrition information is an approximation and can vary based on ingredient brands and measurements.
  • Ensure butter and eggs are at room temperature for the best texture and mixing results.
  • If you prefer chewier cookies, slightly underbake and allow to cool on the sheet.
  • Mini chocolate chips are optional but add extra chocolate bursts.
  • Use powdered sugar dusted on marshmallows to prevent them from sticking together before swirling.
