Ingredients

Scale

Dry Ingredients:

  • 1 ¾ cups (220 g) all-purpose flour
  • 1/2 cup (40 g) unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt

Wet Ingredients:

  • 1/2 cup (115 g) unsalted butter, softened
  • 3/4 cup (150 g) granulated sugar
  • 1/2 cup (100 g) packed light brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract

Mix-Ins:

  • 1/2 cup (90 g) semi-sweet chocolate chips
  • 1 cup (50 g) mini marshmallows
  • 1/3 cup (60 g) marshmallow fluff (optional)

Instructions

  1. Prep the Oven and Ingredients: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats to prevent sticking. Measure out all your ingredients to streamline the process.
  2. Mix the Dry Ingredients: In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. This ensures the cocoa is evenly distributed, and there are no lumps.
  3. Cream the Butter and Sugars: In a large mixing bowl, use a hand or stand mixer to cream the softened butter, granulated sugar, and brown sugar together until light and fluffy, about 2-3 minutes. The mixture should turn pale and airy—this step is essential for a tender cookie.
  4. Add the Wet Ingredients: Beat in the egg and vanilla extract, mixing until fully incorporated. Scrape down the sides of the bowl to ensure everything is well combined.
  5. Combine Wet and Dry: Gradually add the dry ingredients to the wet ingredients in 2-3 additions. Mix on low speed until just combined. Avoid overmixing, as this can lead to tough cookies.
  6. Fold in the Chocolate Chips: Gently fold in the semi-sweet chocolate chips for bursts of melty goodness in every bite.
  7. Add the Marshmallow Swirl: Add the mini marshmallows and dollops of marshmallow fluff (if using) into the dough. Use a spatula to fold them in gently, being careful not to overmix. You want visible streaks of marshmallow throughout the dough for a delightful swirl effect.
  8. Scoop and Bake: Using a cookie scoop or tablespoon, scoop dough onto prepared baking sheets, spacing about 2 inches apart. Bake for 8-10 minutes, or until edges are set but centers remain slightly soft. Watch the marshmallows as they caramelize slightly, adding a toasty flavor.
  9. Cool and Enjoy: Let the cookies cool on the baking sheet for 5 minutes to firm up before transferring to a wire rack to cool completely. This prevents breakage and ensures perfect texture.

Notes

  • For a stronger marshmallow swirl, use the marshmallow fluff; otherwise, mini marshmallows alone will provide gooey texture.
  • Do not overmix the dough after adding dry ingredients to keep cookies tender.
  • Use parchment or silicone mats on baking sheets to prevent sticking and ensure even baking.
  • Store cookies in an airtight container at room temperature for up to 4 days.
  • Optional: Add 1/4 teaspoon espresso powder to enhance the chocolate flavor.
