Fairlife Hot Chocolate Recipe for a Rich, Creamy Mug

This Fairlife hot chocolate is a stovetop drink made with ultra-filtered milk, cocoa powder, and melted chocolate for a smooth, cocoa-rich mug. A little sugar, vanilla, and salt round out the flavor, while gentle heating helps the chocolate melt without scorching the milk.

Ingredients

2 cups (480 ml) Fairlife whole milk: Use plain, unflavored milk. Whole milk makes a fuller drink; 2% Fairlife milk also works.
2 tablespoons (10 g) unsweetened cocoa powder: Sift it if it is lumpy, or press any clumps against the side of the saucepan while whisking.
2 tablespoons (25 g) granulated sugar: This gives a gently sweet result. You can add a little more to taste at the end.
2 ounces (57 g) semisweet chocolate, finely chopped: A chocolate bar melts smoothly and adds richness. Choose a bar rather than chocolate chips if you want the easiest melting; chips may contain stabilizers and can take longer to dissolve.
1 teaspoon (5 ml) vanilla extract: Stir it in after removing the pan from the heat so its aroma stays noticeable.
⅛ teaspoon (about 0.75 g) fine salt: A small pinch balances the cocoa and sweetness without making the drink taste salty.

Instructions

Measure and prepare the ingredients. Measure the milk, cocoa, sugar, and salt. Finely chop the chocolate so it melts quickly and evenly. This preparation takes about 5 minutes; set the vanilla nearby for the final step.
Make a smooth cocoa paste. In a small, heavy-bottomed saucepan, whisk together the cocoa powder, sugar, and salt. Add about ¼ cup (60 ml) of the milk a little at a time, whisking until you have a glossy, lump-free paste. Starting with a small amount of liquid is easier than trying to smooth cocoa powder in a full pan of milk.
Warm the mixture gently. Set the saucepan over medium-low heat and whisk the cocoa paste for 1 minute. Slowly pour in the remaining milk while whisking. Continue heating for about 3 minutes, stirring often, until the milk is hot and steaming but not boiling. Reduce the heat if you see bubbles forming around the edge or the mixture begins to simmer.
Melt in the chocolate. Add the chopped chocolate and stir constantly for about 2 minutes, scraping the bottom and corners of the pan. The drink is ready when the chocolate has melted and the mixture looks even and glossy. Keep the heat low; boiling can make milk stick to the pan and may give the drink a cooked flavor.
Finish and serve. Take the pan off the heat, stir in the vanilla, and taste carefully. Add a little more sugar if you prefer a sweeter mug. Pour into two heat-safe mugs and serve while hot. The complete stovetop cooking time is about 6 minutes once the ingredients are measured.

Tips

Whisk the cocoa into a paste first. Cocoa powder tends to float and clump when it meets a large amount of liquid at once. Mixing it with the sugar and a small splash of milk makes a smooth base, and gradually adding the rest of the milk keeps the texture consistent. If a few small lumps remain, whisk firmly before adding the chocolate.
Keep the heat moderate. Milk can scorch on the bottom of a pan before the surface looks especially hot. Use a heavy-bottomed saucepan, stir frequently, and lower the heat if the drink starts bubbling. You want it hot enough to melt the chocolate, not boiling. Avoid leaving the pan unattended during the final minutes.
Adjust sweetness after the chocolate melts. Chocolate bars vary in sweetness, and cocoa brands can taste more or less bitter. Taste the finished drink before adding extra sugar. If you use milk chocolate instead of semisweet, begin with less sugar or omit it, then sweeten only if needed.
Choose a practical milk substitute. If Fairlife milk is unavailable, use the same amount of regular dairy milk. For a non-dairy version, unsweetened oat milk is a useful swap, though the drink may be less rich and the flavor will change slightly. Use a plain, unflavored variety so it does not compete with the chocolate.

Serving Suggestions

Serve the hot chocolate right after making it, while it is silky and warm. For a simple finish, add a small spoonful of whipped cream, a few mini marshmallows, or a light dusting of cocoa. A little grated chocolate on top melts into the surface and reinforces the chocolate flavor without requiring another sweetener. If serving guests, pour the drink into pre-warmed mugs so it stays hot a little longer; fill each mug with hot tap water for a minute, then empty and dry it before pouring.

This recipe makes two modest servings, roughly one cup (240 ml) each. For a larger after-dinner mug, divide it between two bigger cups or serve with a small cookie, biscotti, or a piece of plain shortbread. The drink is rich enough to pair well with a simple, not-too-sweet snack. For a group, keep the batch in the saucepan over the lowest heat and stir often, but do not let it simmer for a long time because the milk can develop a skin or stick to the bottom.

Variations

Make it darker. Use bittersweet chocolate in place of semisweet, keeping the amount at 2 ounces (57 g). Taste before adding extra sugar, since a higher-cocoa chocolate will make the drink less sweet and more intense. For a particularly cocoa-forward mug, increase the cocoa to 2½ tablespoons (about 13 g), then whisk it into the paste as directed.

Make it sweeter and milder. Replace the semisweet chocolate with milk chocolate and reduce the granulated sugar to 1 tablespoon (12 g), or leave it out initially. Milk chocolate softens the cocoa flavor and makes a sweeter drink, so taste before adding more sugar. The texture should still be smooth as long as you chop the chocolate finely and stir it in over low heat.

Add a warm spice note. Whisk ¼ teaspoon ground cinnamon into the cocoa, sugar, and salt. For a subtle spiced version, add just a small pinch of ground nutmeg as well. Spices can become more prominent as the drink sits, so start with a light hand; you can always dust a little cinnamon over the finished mugs.

Try a peppermint mug. Stir ⅛ teaspoon peppermint extract into the finished drink along with the vanilla, then taste before adding more. Peppermint extract is concentrated, and too much can cover the chocolate. A few crushed peppermint candies on top are another option, but they add sweetness and begin to dissolve quickly.

Storage and Reheating

Let extra hot chocolate cool briefly, then refrigerate it in a covered container within 2 hours of cooking. It keeps well for up to 3 days in the refrigerator. The chocolate may settle or the surface may look slightly separated as it chills; that is normal for a milk-based drink and does not necessarily mean it has spoiled. Stir it before reheating, and discard it if it has been left at room temperature for more than 2 hours.

Reheat only the amount you plan to drink. Warm it in a small saucepan over low heat, whisking often, or microwave it in a microwave-safe mug in 30-second bursts, stirring between each burst. For food safety, reheat leftovers to 165°F (74°C), checking with a food thermometer, then serve promptly. Avoid boiling it, which can scorch the milk and make the chocolate less smooth. Repeated cooling and reheating can affect the texture, so portioning leftovers before storing is helpful.

Frequently Asked Questions

Can I make Fairlife hot chocolate with 2% milk?
Yes. Replace the whole milk with 2 cups (480 ml) of plain Fairlife 2% milk and follow the same method. The drink will be a little lighter in body, but the chopped chocolate still gives it a rounded texture. Skim milk also works, though it will make a noticeably less rich mug.

Can I make this recipe without a chocolate bar?
Yes, although the result will be less thick and less rounded. Leave out the chopped chocolate and increase the cocoa powder to 3 tablespoons (about 15 g). Warm the cocoa paste and milk as directed, then taste and adjust the sugar. Use unsweetened cocoa, not a sweetened hot cocoa mix, because mixes already contain sugar and other ingredients.

Why is my hot chocolate grainy or lumpy?
The usual cause is cocoa powder that was added directly to a large quantity of milk, or chocolate that did not fully melt. Whisk the cocoa with sugar and a small splash of milk first, then add the remaining milk gradually. Chop the chocolate finely and keep stirring over low heat. If the drink is already lumpy, take it off the heat and whisk vigorously; a brief pass with an immersion blender can smooth it, but avoid splashing hot liquid.

Can I make it ahead for a gathering?
You can make it earlier the same day and refrigerate it promptly in a covered container, then reheat it gently when needed. Stir well as it warms because the chocolate may settle. For several servings, scale each ingredient evenly and use a larger saucepan, leaving room to whisk. Do not leave a milk-based batch sitting out for guests; keep it refrigerated until reheating or serve it shortly after preparation.

Can I prepare it in the microwave?
Yes, but use a large microwave-safe bowl to prevent spills. Whisk the cocoa, sugar, salt, and a little milk into a paste first. Add the remaining milk and chopped chocolate, then microwave in 30-second intervals, stirring thoroughly each time until hot and smooth. Microwaves heat unevenly, so careful stirring matters; do not heat it in one long burst or let it boil over.

Can I double the recipe?
Yes. Double every ingredient and use a medium saucepan. The larger quantity will take longer to heat than the two-serving batch, so judge doneness by the drink becoming steaming and the chocolate fully melting rather than relying only on the original timing. Stir frequently, especially across the bottom of the pan, and divide into mugs once it is evenly mixed.
