Method
- Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper and set aside.
- In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt until well combined.
- In a large mixing bowl, cream the softened butter, granulated sugar, and brown sugar together until light and fluffy, about 2 minutes.
- Add the egg, vanilla extract, and milk to the butter mixture. Beat until smooth and fully combined.
- Gradually add the dry ingredients to the wet ingredients, mixing just until a thick, soft dough forms. Do not overmix.
- Fold in the chocolate chips and about 1/2 cup of the mini marshmallows, distributing them evenly throughout the dough.
- Scoop about 2 tablespoons of dough per cookie and place onto the prepared baking sheets, spacing them 2 inches apart.
- Gently press 3–4 mini marshmallows into the top of each dough ball for a gooey, toasted marshmallow topping.
- Bake for 9–10 minutes, or until the edges are set but the centers still appear soft and slightly underbaked.
- Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. Enjoy warm for the best hot chocolate cookie experience.
Notes
For extra gooey cookies, press a few additional mini marshmallows on top of the cookies right after baking. You can also swap in dark chocolate chips or a pinch of espresso powder to deepen the chocolate flavor.
