Ingredients

Scale
  • 1 ¾ cups (220g) all-purpose flour
  • ½ cup (50g) unsweetened cocoa powder
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • ½ cup (115g) unsalted butter, softened
  • ¾ cup (150g) granulated sugar
  • ¼ cup (50g) packed brown sugar
  • 1 large egg, room temperature
  • 1 teaspoon pure vanilla extract
  • ¾ cup (130g) bittersweet chocolate chunks
  • 1 cup (approx. 50g) mini marshmallows

Instructions

  1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat for easy cleanup.
  2. In a medium bowl, whisk together 1 ¾ cups (220g) all-purpose flour, ½ cup (50g) unsweetened cocoa powder, ½ teaspoon baking soda, and ¼ teaspoon salt. Set aside.
  3. In a large bowl, use an electric mixer to beat ½ cup (115g) softened unsalted butter, ¾ cup (150g) granulated sugar, and ¼ cup (50g) packed brown sugar until light and fluffy (about 2-3 minutes). Scrape down the sides as needed.
  4. Beat in 1 large room temperature egg and 1 teaspoon pure vanilla extract until combined and smooth.
  5. Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Avoid overmixing to keep cookies tender.
  6. Use a rubber spatula to gently fold in ¾ cup (130g) bittersweet chocolate chunks and 1 cup (50g) mini marshmallows. Be careful not to crush the marshmallows to keep their gooey texture intact.
  7. Using a cookie scoop or tablespoon, drop rounded balls of dough about 2 inches apart on the prepared baking sheet. Don’t flatten them — they’ll spread nicely on their own.
  8. Place in the oven for 10-12 minutes. The edges should be set and slightly crisp, but the centers will look soft and puffy.
  9. Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack. This resting time helps the marshmallows set just enough for gooey centers without being runny.

Notes

Gently fold marshmallows to keep gooey texture; watch baking time closely to avoid burning marshmallows; use mini marshmallows for best results; chill dough 15-20 minutes if too soft; tent cookies with foil if marshmallows brown too quickly.
