Ingredients

Scale

Wet Ingredients

  • 1/2 cup (8 Tbsp; 113g) unsalted butter, softened to room temperature
  • 1/2 cup (100g) granulated sugar
  • 1/2 cup (100g) packed light or dark brown sugar
  • 1 large egg, at room temperature
  • 1 teaspoon pure vanilla extract
  • 2 teaspoons (10ml) milk (any kind, dairy or nondairy, is fine)

Dry Ingredients

  • 1 and 1/2 cups (188g) all-purpose flour (spooned & leveled)
  • 1/3 cup (27g) natural unsweetened cocoa powder
  • 1/4 cup (40g) dry hot cocoa mix
  • 1 teaspoon baking soda
  • 1/8 teaspoon salt

Toppings

  • 1011 large marshmallows, cut in half
  • 8 ounces (226g) semi-sweet chocolate, finely chopped

Instructions

  1. Cream Butter and Sugars: In a large bowl using a handheld or stand mixer fitted with a paddle attachment, beat the butter, granulated sugar, and brown sugar together on medium high speed until fluffy and light in color, about 2–3 minutes.
  2. Add Egg and Vanilla: Add the egg and vanilla extract, and then beat on high speed until combined. Scrape down the sides and bottom of the bowl as needed.
  3. Combine Dry Ingredients: In a separate bowl, whisk the flour, cocoa powder, hot cocoa mix, baking soda, and salt together until combined.
  4. Make Cookie Dough: Add the dry ingredients to the wet mixture and beat on low until combined. The dough will be thick. Beat in the milk until you have a thick and sticky cookie dough.
  5. Chill Dough: Cover dough tightly and chill in the refrigerator for at least 2 hours and up to 3 days. Chilling is imperative to handle the sticky dough properly.
  6. Preheat Oven and Prepare Baking Sheets: Preheat oven to 350°F (177°C). Line large baking sheets with parchment paper or silicone baking mats and set aside.
  7. Shape Cookies: Remove dough from the fridge. Scoop and roll heaping 1 tablespoon (about 25-26g) portions into balls. Arrange them 2-3 inches apart on the prepared baking sheets.
  8. Bake Cookies: Bake for 10 minutes. Remove from oven and lightly press a marshmallow half into the top of each cookie.
  9. Finish Baking: Return cookies to the oven and bake for 2 more minutes. Remove and gently press down on the marshmallow with the back of a spoon to slightly flatten it.
  10. Cool Cookies: Cool cookies on the baking sheet for 10 minutes, then transfer to a wire rack to cool completely.
  11. Melt Chocolate: Melt chopped semi-sweet chocolate in a double boiler or microwave (in 20-second increments, stirring between intervals) until smooth.
  12. Decorate Cookies: Spoon melted chocolate over each cooled marshmallow-topped cookie. Allow chocolate to set at room temperature for 30-60 minutes.
  13. Store: Once chocolate has set, stack, store, transport, or gift the cookies. Store leftover cookies tightly covered at room temperature for up to 1 week.

Notes

  • Chilling the dough is crucial because this cookie dough is thick and sticky, making it easier to handle.
  • You can use any type of milk — dairy or nondairy — when adding to the dough.
  • To melt the chocolate, a double boiler provides gentle heat without risk of burning, but a microwave works fine if you stir frequently.
  • These cookies keep well for up to one week stored at room temperature in an airtight container.
  • Pressing down on the marshmallow after baking helps it flatten and meld with the cookie for a better texture and appearance.
