Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Each ingredient plays a key role in creating that signature hot chocolate flavor and fudgy brownie texture.

Dark chocolate – A rich, slightly bitter chocolate gives these cookies depth and prevents them from being overly sweet. Choose at least 60% cocoa for best results.

Unsalted butter – Provides richness and a velvety texture. You can also use browned butter for a slightly nutty flavor.

Granulated sugar – Creates that glossy, crinkly top layer reminiscent of a perfect brownie.

Brown sugar – Adds moisture and a caramel undertone that complements the cocoa beautifully.

Eggs – Essential for structure and chewiness; they bind everything together while keeping the cookies soft in the middle.

All-purpose flour – Gives the cookies body without making them cakey. A little goes a long way here.

Cocoa powder – Reinforces the chocolate flavor and gives the cookies their rich, dark color.

Hot chocolate mix – The secret ingredient that transforms these from ordinary brownies into a hot cocoa dream. Use your favorite brand for the best flavor.

Baking powder – Adds a little lift, ensuring the cookies aren’t too dense.

Salt – Balances sweetness and enhances the depth of the chocolate.

Vanilla extract – Adds warmth and complements the chocolate beautifully.

Mini marshmallows – Melt into gooey pockets throughout the cookies, creating that classic hot chocolate feel.

Chocolate chips – Double up the chocolate intensity; I like a mix of milk and dark chips for balance.

Directions

Preheat your oven to 350°F (175°C) and line two baking trays with parchment paper. In a heatproof bowl, melt the dark chocolate and butter together until smooth and glossy. Let it cool slightly. In a separate bowl, whisk the granulated sugar, brown sugar, and eggs until the mixture becomes light and slightly thick. Pour in the melted chocolate mixture and stir to combine. Add the vanilla extract.

In another bowl, sift together flour, cocoa powder, hot chocolate mix, baking powder, and salt. Fold the dry ingredients into the wet mixture until just combined. Add chocolate chips and gently fold in mini marshmallows, being careful not to overmix.

Scoop the dough onto the prepared baking sheets using a cookie scoop, leaving space between each cookie as they spread slightly. Bake for 10–12 minutes, until the edges are set and the centers look soft. Let the cookies cool on the tray for a few minutes before transferring them to a wire rack. The result? Chewy, gooey, and unbelievably rich hot chocolate brownie cookies.

FAQs
