Ingredients You’ll Need
This Viral NYC Hot Chocolate Recipe thrives on simplicity and quality. Each ingredient plays a crucial role: some build depth in flavor, others add the perfect creamy consistency, and a few create that iconic toasted marshmallow finish that makes this drink unforgettable.
- 3 large egg whites: Essential for creating the fluffy marshmallow topping with just the right texture and stability.

- 1½ cups evaporated milk (354mL): Richer than regular milk, this gives the hot chocolate a velvety full-bodied flavor.
- 1½ cups whole milk (360mL): Balances creaminess with a smooth, milky taste.
- ½ cup heavy cream (120mL): Adds luscious richness and a silky mouthfeel to the cocoa.
- ½ cup light brown sugar (100g, packed): Infuses subtle caramel notes that deepen the sweetness.
- ¼ cup Dutch-process cocoa powder (25g): Offers an intense, mellow chocolate flavor with a dark color.
- â…› teaspoon sea salt: Enhances all the flavors and balances sweetness perfectly.
- 4 ounces semi-sweet chocolate (chopped): Melts into a smooth, luscious chocolate base that defines the drink.
- 1 tablespoon vanilla bean paste: Enriches the flavor with a natural vanilla depth that’s more vibrant than extract.
- Whipped cream: The final indulgent touch that crowns the hot cocoa in perfect creaminess.
How to Make Viral NYC Hot Chocolate Recipe
Step 1: Create the Marshmallow Fluff
Begin by preparing a double boiler setup: fill a medium saucepan with two inches of water and bring it to a low boil over medium heat. In a heatproof bowl larger than the pot’s mouth, whisk together the egg whites, granulated sugar, and cream of tartar. Place the bowl atop the saucepan, careful that it doesn’t touch the water below. Whisk continuously over medium-high heat until the mixture reaches 160ºF and you no longer feel sugar granules between your fingers. Then transfer the warmed mixture into your stand mixer bowl, add the vanilla extract, and beat on high speed until stiff peaks form. This glossy marshmallow fluff will be the crowning glory of your hot chocolate.
Step 2: Prepare the Hot Cocoa Base
In another saucepan, whisk the evaporated milk, whole milk, heavy cream, brown sugar, Dutch-process cocoa powder, and sea salt together. Heat the mixture over medium heat until the sugar dissolves completely. Then add the chopped semi-sweet chocolate and stir until you achieve a smooth and creamy texture. Stir in the vanilla bean paste for that extra layer of flavor, and bring the hot chocolate to a gentle simmer over low heat. Once ready, remove from heat and pour into mugs.
Step 3: Assemble and Toast
Using a piping bag or jar, spoon the marshmallow fluff inside the mugs, swirling around the inner walls and building a rim of fluffy delight on top. Take a kitchen torch and gently toast the fluff until it turns golden brown and slightly caramelized. Finally, finish with a generous scoop of whipped cream for one more dreamy texture to elevate every sip.
How to Serve Viral NYC Hot Chocolate Recipe
Garnishes
This Viral NYC Hot Chocolate Recipe truly shines with its signature marshmallow fluff topping, but you can also add a sprinkle of cinnamon or a dusting of cocoa powder to boost its visual and aromatic appeal. A few chocolate shavings or crushed peppermint sticks add seasonal flair and an extra burst of flavor.
Side Dishes
Pair this decadent hot chocolate with buttery shortbread cookies, crispy biscotti, or even a warm slice of cinnamon swirl bread. These sides provide satisfying textures and complementary flavors, creating a cozy indulgence perfect for snuggling up on any day.
Creative Ways to Present
Presentation is half the fun! Serve the hot chocolate in clear glass mugs so you can admire the glossy layers of cocoa and marshmallow fluff. Rim the glasses with crushed graham crackers for a s’mores twist, or try colorful sprinkles on the whipped cream to delight kids and bring festive cheer.
Make Ahead and Storage
Storing Leftovers
If you have any marshmallow fluff or hot chocolate base left, store them separately in airtight containers in the fridge. The fluff stays fresh for about 2 days while the cocoa base will keep well for up to 3 days. Ensuring the fluff stays dry will keep it ready for piping later.
Freezing
While freezing the hot chocolate base is possible, it’s better to freeze it in ice cube trays for individual portions. Thaw completely in the fridge before reheating. The marshmallow fluff, however, doesn’t freeze well and is best made fresh whenever possible.
Reheating
Gently reheat the hot chocolate base over low heat, stirring often to prevent scorching. Avoid boiling as it can alter the creamy texture. Refresh the drink by piping fresh marshmallow fluff on top to recreate that perfect toasted finish.
FAQs
Can I use regular cocoa powder instead of Dutch-process?
Yes, you can substitute regular cocoa powder, but Dutch-process provides a smoother, less acidic taste and darker color that really elevates this Viral NYC Hot Chocolate Recipe.
Is it safe to use raw egg whites in this recipe?
The egg whites are gently heated to 160ºF in a double boiler, which is enough to reduce risk while creating the perfect marshmallow mixture.
Can I make this recipe vegan?
You can experiment by replacing dairy with plant-based milks and using aquafaba instead of egg whites, but it won’t have the same richness or marshmallow texture that defines this viral favorite.
What if I don’t have a kitchen torch?
No problem! You can brown the marshmallow fluff under a hot broiler for a few seconds. Watch carefully to avoid burning.
How do I store leftover marshmallow fluff?
Store leftover fluff in an airtight container in the fridge for up to two days. Whisk lightly before using if it separates.
