Ingredients

Scale
  • 2 cups (240 g) all-purpose flour
  • 3/4 cup (75 g) unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3/4 cup (170 g) unsalted butter, softened
  • 3/4 cup (150 g) granulated sugar
  • 1/2 cup (100 g) packed brown sugar
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 1 teaspoon instant espresso powder (optional)
  • 1 1/2 cups (about 85 g) mini marshmallows

Instructions

  1. Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper and set aside.
  2. In a medium bowl, sift together the flour, cocoa powder, baking soda, and salt. Whisk to combine and set aside.
  3. In a large bowl, use an electric mixer to beat the softened butter, granulated sugar, and brown sugar until light and fluffy, about 3-4 minutes.
  4. Beat in the eggs one at a time, then mix in the vanilla extract and instant espresso powder if using.
  5. Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined. Avoid overmixing.
  6. Gently fold in the mini marshmallows using a spatula, being careful not to overmix.
  7. Using a cookie scoop or tablespoon, drop rounded mounds of dough onto the prepared baking sheets, spacing about 2 inches apart.
  8. Bake for 10-12 minutes, or until the edges are set but the centers still look soft.
  9. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Notes

Use mini marshmallows for even melting and gooey texture. Chill dough for 15 minutes if butter is too soft or kitchen is warm. Watch baking time closely to avoid marshmallows burning. Espresso powder enhances chocolate flavor without coffee taste. Dough can be refrigerated up to 24 hours before baking. Cookies freeze well for up to 3 months.
