Equipment
Method
- Whisk the flour, cocoa powder, hot cocoa mix, baking soda, and salt in a medium bowl.
- Beat the butter, granulated sugar, and brown sugar in a large bowl with a mixer on medium speed for 2 to 3 minutes, until fluffy.
- Beat in the eggs one at a time.
- Beat in the vanilla until combined.
- Add the flour mixture and mix on low just until no dry streaks remain.
- Fold in the chocolate chips.
- Cover and chill the dough for 30 minutes.
- Heat the oven to 350°F.
- Line two 18x13-inch baking sheets with parchment paper.
- Scoop the dough into 24 portions, about 2 tablespoons each, and arrange 12 on each baking sheet, leaving space between them.
- Bake one sheet at a time on the center rack for 8 minutes.
- Remove the sheet from the oven and place a marshmallow half, cut side down, on each cookie.
- Return the sheet to the oven for 2 to 3 minutes, until the marshmallows puff and the cookie edges are set, then repeat with the second sheet.
- Cool the cookies on the baking sheets for 5 minutes.
- Transfer the cookies to a wire rack to cool.
Notes
For puffy toppings, place each marshmallow half cut side down. Store in an airtight container in the refrigerator for up to 5 days; freezer: yes. For a dairy-free variation, choose dairy-free butter, chocolate chips, cocoa mix, and marshmallows.
