Ingredients

Scale
  • 2 ¼ cups all-purpose flour
  • ½ cup unsweetened cocoa powder
  • 1 tsp baking soda
  • ½ tsp salt
  • 1 cup unsalted butter, softened
  • ¾ cup granulated sugar
  • ¾ cup brown sugar
  • 2 large eggs
  • 2 tsp vanilla extract
  • 1 ½ cups mini marshmallows

Instructions

  1. Preheat the oven to 180°C (350°F) and line two baking sheets with parchment paper.
  2. In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt until well combined.
  3. In a large bowl, cream the butter with granulated sugar and brown sugar until light and fluffy.
  4. Beat in the eggs one at a time, followed by vanilla extract, ensuring each is fully incorporated.
  5. Gradually add the flour mixture to the butter mixture, mixing slowly until just combined. Avoid overmixing to keep cookies tender.
  6. Gently fold in the mini marshmallows with a spatula, ensuring even distribution without crushing them.
  7. Using a tablespoon or small cookie scoop, drop dough onto prepared baking sheets, spacing them 5 cm (2 inches) apart.
  8. Optional: Press a few extra marshmallows on top or gently swirl them into the dough for visual appeal.
  9. Bake for 10–12 minutes, until edges are set but centers remain soft.
  10. Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

Notes

For extra flavor, add chocolate chips or nuts.

Dough can be refrigerated for 24 hours before baking to enhance flavor.

Slightly underbaking ensures a chewy center.

Store in an airtight container at room temperature for up to 5 days.
