These Marshmallow-Surprise Hot Cocoa Cookies combine all the cozy flavors of hot chocolate into a chewy, decadent cookie. Topped with gooey marshmallows and a chocolate drizzle, they hide a sweet surprise inside—perfect for the holidays or any cold-weather treat.


Ingredients

Units Scale

For the cookies:

  • 1/2 cup (115 g) unsalted butter, softened
  • 1/2 cup (100 g) granulated sugar
  • 1/2 cup (100 g) light brown sugar, packed
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 cup (125 g) all-purpose flour
  • 1/2 cup (45 g) unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/4 cup (60 ml) milk
  • 12 large marshmallows, cut in half

For the topping:

  • 1/2 cup (85 g) semi-sweet chocolate chips
  • 1 teaspoon coconut oil or vegetable oil (optional, for melting)
  • Sprinkles (optional, for decoration)

Instructions

  1. Preheat the oven:
    • Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper or silicone baking mats.
  2. Make the cookie dough:
    • In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy (about 2 minutes).
    • Beat in the egg and vanilla extract until smooth.
    • In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
    • Add the milk and mix until the dough is smooth.
  3. Scoop and bake the cookies:
    • Scoop tablespoon-sized portions of dough onto the prepared baking sheets, spacing them about 2 inches apart.
    • Bake for 8 minutes, or until the edges are set but the centers are still soft.
  4. Add the marshmallow surprise:
    • Remove the cookies from the oven and gently press half a large marshmallow into the center of each cookie.
    • Return the cookies to the oven and bake for an additional 2–3 minutes, or until the marshmallows puff up and soften.
    • Allow the cookies to cool for 5 minutes on the baking sheet before transferring them to a wire rack to cool completely.
  5. Prepare the chocolate drizzle:
    • Melt the chocolate chips in the microwave in 20-second intervals, stirring between each, until smooth. Stir in the coconut oil or vegetable oil if using (this helps thin the chocolate for drizzling).
  6. Decorate the cookies:
    • Drizzle the melted chocolate over the cooled cookies and sprinkle with festive sprinkles, if desired.
  7. Serve and enjoy:
    • Let the chocolate drizzle set for about 15 minutes. Serve the cookies with a warm cup of hot cocoa or milk for the ultimate cozy treat.

 


Notes

  • Storage: Store cookies in an airtight container at room temperature for up to 3 days.
  • Reheating tip: Warm the cookies in the microwave for 5–10 seconds to make the marshmallow gooey again.
  • Add-ins: Stir in 1/2 cup of mini chocolate chips or crushed peppermint for an extra twist.
