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
- 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
- 2 teaspoons (10ml) milk (any kind, dairy or nondairy, is fine)
- 10-11 large marshmallows, cut in half
- 8 ounces (226g) semi-sweet chocolate, finely chopped (see Note)
Cookie Dough Preparation
1. Cream the Butter and Sugars: In a large mixing bowl, combine the softened unsalted butter, granulated sugar, and packed brown sugar. Using an electric mixer (or a sturdy whisk and some elbow grease), beat these ingredients together until the mixture is light, fluffy, and well combined. This usually takes about 2-3 minutes. The creaming process incorporates air into the dough, which is crucial for a tender cookie texture. Make sure your butter is truly softened – it should yield to gentle pressure but not be melted or greasy. This step sets the foundation for a wonderfully chewy cookie.
2. Incorporate Wet Ingredients: Add the large egg and pure vanilla extract to the creamed butter and sugar mixture. Beat again until everything is thoroughly combined and smooth. Ensure the egg is at room temperature; this helps it emulsify better with the other ingredients, preventing a greasy dough. If your eggs are cold, you can quickly warm them by placing them in a bowl of warm (not hot) water for about 5 minutes.
3. Combine Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, natural unsweetened cocoa powder, dry hot cocoa mix, baking soda, and salt. Whisking the dry ingredients together ensures that the leavening agents (baking soda) and salt are evenly distributed throughout the flour mixture, which is essential for consistent cookie rise and flavor. Sifting the dry ingredients can also help create an even lighter texture, though it’s not strictly necessary for this recipe.
4. Mix Wet and Dry: Gradually add the dry ingredients to the wet ingredients in the large mixing bowl, mixing on low speed (or by hand with a spatula) until just combined. Be careful not to overmix the dough at this stage. Overmixing can develop the gluten in the flour too much, leading to tough cookies. Once you no longer see streaks of dry flour, add the 2 teaspoons of milk and mix briefly until the dough just comes together. The dough will be quite thick and rich.
Assembling and Baking the Cookies
5. Forming the Cookie Base and Adding the Surprise: Now for the fun part! Line two baking sheets with parchment paper. Parchment paper prevents the cookies from sticking and makes for easy cleanup. Scoop about 1.5 to 2 tablespoons of dough and roll it into a ball. Gently flatten the ball slightly in your palm. Next, take a piece of the cut marshmallow and place it in the center of the flattened dough. Now, take another similar-sized portion of dough (about 1 tablespoon) and gently flatten it to place on top of the marshmallow, creating a pocket around it. Pinch the edges of the bottom dough around the marshmallow and seal it completely with the top dough, ensuring the marshmallow is fully enclosed. Roll the dough ball gently between your hands to create a smooth, round cookie shape. Repeat this process with the remaining dough and marshmallows. For the chocolate surprise, gently press some of the finely chopped semi-sweet chocolate into the top and sides of each cookie dough ball. This adds another layer of chocolatey goodness that will melt beautifully during baking.
6. Baking to Perfection: Place the prepared cookie dough balls onto the lined baking sheets, spacing them about 2 inches apart to allow for spreading. Preheat your oven to 350°F (175°C). Bake for 10-12 minutes, or until the edges are set and slightly puffed, and the centers still look a little soft and underbaked. It’s crucial not to overbake these cookies, as they will continue to set up as they cool. The goal is a chewy cookie with a molten center. If you prefer a crispier cookie, you can bake for a minute or two longer, but be mindful of the marshmallow.
7. Cooling and Enjoying: Once baked, remove the cookies from the oven and let them cool on the baking sheets for 5-10 minutes. This allows them to firm up enough to be moved. Then, carefully transfer them to a wire rack to cool completely. As they cool, the semi-sweet chocolate will become beautifully melted and gooey, and the marshmallow inside will be a warm, gooey surprise waiting to be discovered.
Note on Chocolate:
Finely chopped chocolate is recommended over chocolate chips because it melts more smoothly and evenly, creating a luxurious chocolate river within your cookie. You can chop a good quality chocolate bar by hand or use a food processor for a finer texture.

Conclusion:
And there you have it – the ultimate guide to creating these delightful Marshmallow-Surprise Hot Cocoa Cookies! These cookies are an absolute triumph, blending the rich, comforting flavor of hot cocoa with the gooey, melt-in-your-mouth surprise of a perfectly baked marshmallow.

I highly recommend serving them warm, straight from the oven, with a tall glass of milk or, of course, a steaming mug of hot cocoa. For a delightful twist, consider adding a pinch of cinnamon or a dash of cayenne pepper to the cookie dough for a little warmth, or stir in some mini chocolate chips for an extra chocolatey punch. I truly encourage you to give these Marshmallow-Surprise Hot Cocoa Cookies a try – you won’t be disappointed!
Frequently Asked Questions:
Can I make these cookies ahead of time?
Absolutely! These cookies store wonderfully. Once completely cooled, keep them in an airtight container at room temperature for up to 3-4 days. They might lose a little of their gooeyness over time, but they still taste fantastic.
What’s the best way to store the marshmallow centers?
When assembling, try to keep the marshmallows from drying out before you wrap them in dough. You can even slightly flatten the marshmallow pieces before placing them in the dough center. This helps them melt more evenly and ensures that wonderful gooey surprise in every bite.
My marshmallows melted completely, what went wrong?
If your marshmallows completely disappeared, it’s likely they were exposed to too much direct heat for too long, or perhaps they were very old and dry. Ensure you’re not overbaking the cookies – they should be slightly underbaked in the center to allow for residual heat to melt the marshmallow perfectly. Using fresh, plump marshmallows is also key!
