Key Ingredients
For the Cookie Base:
- 1 cup (225 g) unsalted butter, softened (Recommended: Kerrygold Grass-Fed Irish Butter for rich, creamy flavor)
- 1 cup (200 g) brown sugar
- ½ cup (100 g) granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 cups (250 g) all-purpose flour (Recommended: King Arthur All-Purpose Flour)
- ¾ cup (75 g) unsweetened cocoa powder
- 1 teaspoon baking soda
- ½ teaspoon salt
For the Mix-Ins:
- 1 cup (170 g) chocolate chips or chunks
- 1 cup mini marshmallows
Substitution Notes: For a gluten-free version, use Bob’s Red Mill 1-to-1 Gluten Free Flour as a direct substitute. Dark chocolate chips create a more intense flavor, while milk chocolate chips make them sweeter. Regular-sized marshmallows can be cut into quarters if mini marshmallows aren’t available.
Step-by-Step Instructions
1. Preheat and Prep Preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper or a silicone baking mat. This prevents sticking and ensures even browning on the bottom of your cookies.
2. Cream Butter and Sugars In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar using an electric mixer on medium speed. Beat for about 2 to 3 minutes until the mixture becomes light, fluffy, and pale in color. This incorporates air for tender cookies with the perfect texture.
3. Add Eggs and Vanilla Add the eggs one at a time, beating well after each addition until fully incorporated. Mix in the vanilla extract until the batter is smooth and well combined. The mixture should look glossy and cohesive.
4. Combine Dry Ingredients In a separate medium bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt. Whisking ensures the leavening agent and cocoa are evenly distributed throughout the flour, preventing lumps and ensuring consistent chocolate flavor in every cookie.
5. Mix Wet and Dry Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed or stirring with a wooden spoon. Mix just until the flour is fully incorporated and no dry streaks remain. The dough will be thick, rich, and deeply chocolatey. Avoid overmixing to keep your cookies tender rather than tough.
6. Fold in the Magic Gently fold in the chocolate chips and mini marshmallows using a spatula or wooden spoon. Distribute them evenly throughout the dough so every cookie gets a perfect amount of gooey chocolate and toasted marshmallow goodness.
7. Scoop and Space Using a tablespoon or cookie scoop (about 1.5 tablespoons), portion out the dough onto your prepared baking sheet. Leave about 2 inches of space between each cookie to allow for spreading during baking. For extra marshmallow appeal, you can press a few additional mini marshmallows on top of each dough ball.
8. Bake to Perfection Bake for 9 to 11 minutes, until the edges are set and look slightly firm, but the centers still appear soft and slightly underdone. The marshmallows on top will puff up and get lightly golden. Don’t overbake—these cookies continue to cook on the hot baking sheet after removing from the oven.
9. Cool Properly Let the cookies rest on the baking sheet for 3 to 5 minutes to finish setting. They’ll be very delicate straight out of the oven. Then carefully transfer them to a wire cooling rack to cool completely, or enjoy them warm when they’re at their gooiest!

Storage & Make-Ahead Tips
Room Temperature Storage: Store completely cooled cookies in an airtight container at room temperature for up to 5 days. Place parchment paper between layers to prevent them from sticking together, especially if the marshmallows are still soft.
Freezing Baked Cookies: These cookies freeze wonderfully for up to 3 months. Let them cool completely, then place in a single layer on a baking sheet and freeze until solid (about 1 hour). Transfer to a freezer-safe container or bag with parchment paper between layers. Thaw at room temperature or warm briefly in the microwave for 10-15 seconds for that fresh-baked texture.
Freezing Cookie Dough: Scoop the dough into balls and freeze on a baking sheet until solid, then transfer to a freezer bag. Bake from frozen, adding 1-2 extra minutes to the baking time. This is perfect for having fresh-baked cookies whenever a craving hits!
Make-Ahead Instructions: Prepare the dough up to 2 days in advance and store it covered in the refrigerator. Let it sit at room temperature for 10-15 minutes before scooping if it becomes too firm. You can also scoop the dough balls ahead of time, cover them on the baking sheet with plastic wrap, and refrigerate for up to 24 hours before baking.
Reheating Tip: To restore that just-baked gooey texture, microwave a cookie for 8-10 seconds or warm in a 300°F oven for 3-5 minutes. The marshmallows will soften and the chocolate will get melty again.
Tips & Tricks
Don’t Overbake: The secret to ultra-soft, gooey cookies is pulling them from the oven when they still look slightly underdone in the center. They’ll firm up as they cool on the baking sheet. Overbaked cookies will be dry and cakey rather than fudgy and chewy.
Room Temperature Butter Matters: Softened butter should be cool to the touch but leave an indentation when pressed. Butter that’s too warm or melted will cause cookies to spread too much and lose their texture. If you forgot to soften your butter, cut it into small cubes and let it sit for 15-20 minutes.
Maximize Marshmallow Appeal: Press a few extra mini marshmallows onto the tops of the dough balls just before baking. They’ll get beautifully toasted and create that authentic hot chocolate look. You can even torch them lightly after baking for extra s’mores vibes!
Common Mistakes to Avoid
- Using cold butter – Cold butter won’t cream properly with the sugar, resulting in dense, flat cookies that don’t have the right texture
- Overmixing the dough – Once you add the flour, mix just until combined; overmixing develops gluten and makes cookies tough
- Baking at the wrong temperature – An oven that’s too hot will burn the edges before the centers cook; use an oven thermometer to verify accuracy
- Crowding the baking sheet – Cookies need space to spread; too close together and they’ll merge into one giant cookie blob
- Skipping the cooling time on the pan – Moving cookies too soon causes them to break apart; they need those few minutes to set properly
Chef’s Advice
Flavor Variations:
- Add 1 teaspoon of espresso powder to the dry ingredients to intensify the chocolate flavor without adding coffee taste
- Mix in ½ teaspoon of peppermint extract for hot chocolate peppermint cookies perfect for the holidays
- Stir in ½ cup of crushed graham crackers for a s’mores-inspired twist
- Add ¼ teaspoon of cinnamon and a pinch of cayenne for Mexican hot chocolate cookies with a subtle kick
Ingredient Substitutions:
- Coconut oil can replace butter for a dairy-free version (use refined for no coconut flavor)
- Replace chocolate chips with white chocolate chips or peanut butter chips for different flavor profiles
- Swap mini marshmallows for marshmallow bits (they won’t melt as much but add great texture)
- Use half whole wheat flour for a slightly nuttier, heartier cookie
Presentation Ideas:
- Dust cooled cookies lightly with powdered sugar for a snowy, festive appearance
- Drizzle with melted white chocolate in a crosshatch pattern for elegant contrast
- Top each cookie with a large marshmallow and torch it for a dramatic s’mores presentation
- Serve on a platter with crushed candy canes sprinkled around for holiday flair
- Stack three cookies and dust with cocoa powder for a rustic, bakery-style look
Size Variations: Make giant bakery-style cookies by using ¼ cup of dough per cookie and baking for 12-14 minutes. Or create bite-sized cookies with 1 teaspoon of dough, baking for just 6-8 minutes—perfect for cookie trays and parties.
History and Cultural Significance
Hot chocolate has been enjoyed for thousands of years, dating back to the ancient Mayans and Aztecs who consumed it as a bitter, ceremonial beverage. When chocolate arrived in Europe in the 16th century, sugar was added, transforming it into the sweet treat we know today. The addition of marshmallows is a more recent American innovation, popularized in the early 20th century when marshmallows became mass-produced and affordable.
The concept of translating beloved beverage flavors into cookie form became a popular baking trend in the 2000s, as home bakers and food bloggers sought creative ways to capture nostalgic flavors in new formats. Hot chocolate cookies specifically gained traction on Pinterest and food blogs around 2010, as the visual appeal of toasted marshmallows on chocolate cookies proved irresistible for social media sharing.
These cookies represent the broader trend of “mash-up” desserts that combine multiple beloved treats into one indulgent creation. Much like cronut or brookies (brownie-cookies), hot chocolate cookies satisfy our desire for innovation while honoring traditional comfort foods. They’ve become especially popular during the winter holidays, appearing at cookie exchanges, holiday parties, and as edible gifts throughout the season.
The enduring appeal of hot chocolate cookies speaks to our collective nostalgia for simple childhood pleasures—coming inside from the cold to a warm, sweet treat that makes everything feel cozy and right.
