These marshmallow-surprise hot cocoa cookies are rich, chocolatey, and filled with a gooey marshmallow centre. Perfect for cosy winter days, they taste just like a cup of hot cocoa in cookie form.
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
Mix Dry Ingredients:
In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt.
Make the Dough:
In a large bowl, beat together butter, granulated sugar, and brown sugar until fluffy. Add the egg, vanilla extract, and milk, mixing until combined. Gradually add the dry ingredients to form a dough.
Shape the Cookies:
Scoop tablespoon-sized portions of dough and roll into balls. Place them 2 inches apart on the prepared baking sheet. Flatten slightly and press a half-marshmallow into the centre, covering it completely with dough.
Bake:
Bake for 8–10 minutes until the cookies are set around the edges. Cool on the baking sheet for 5 minutes, then transfer to a wire rack.
Prepare the Chocolate Topping (Optional):
Melt chocolate chips and butter together until smooth. Drizzle over cooled cookies if desired.
