Hot Chocolate Recipe Using Hershey’s Cocoa on the Stove

This hot chocolate recipe using Hershey’s cocoa makes two mugs of a classic stovetop drink with unsweetened cocoa powder, milk, sugar, and vanilla. A smooth cocoa paste helps prevent lumps, while gentle heating brings the flavors together without scorching the milk.

Ingredients

Use unsweetened Hershey’s cocoa powder, not chocolate drink mix, which already contains sugar and other ingredients. Whole milk gives the richest texture, but the alternatives below work well too. The optional toppings are enough for two mugs.

2 tablespoons (10 g) unsweetened Hershey’s cocoa powder
2 tablespoons (25 g) granulated sugar
⅛ teaspoon (about 0.7 g) fine salt
2 cups (480 ml) whole milk, divided
¼ teaspoon (1 ml) vanilla extract
½ cup (about 25 g) mini marshmallows, optional
2 tablespoons (30 ml) whipped cream, optional
⅛ teaspoon (about 0.3 g) ground cinnamon, optional

Instructions

Measure and combine the dry ingredients. Add the cocoa powder, sugar, and salt to a small bowl or directly to a medium saucepan. Stir them together with a small whisk or fork so the salt is distributed and any cocoa clumps are broken up. Cocoa can pack into small lumps in its container, so take a moment to crush them before adding liquid.
Make a smooth cocoa paste. Measure ¼ cup (60 ml) of the milk from the recipe and pour it into the cocoa mixture a little at a time, whisking as you go. Start with just a splash; the mixture will look thick and dark at first. Keep whisking and add the rest of that ¼ cup until the paste is smooth, with no dry pockets of cocoa along the bowl or pan. This small step is more reliable than adding all the milk at once.
Add the remaining milk. Pour in the remaining 1¾ cups (420 ml) milk and whisk until the cocoa paste is fully incorporated. If you made the paste in a bowl, transfer everything to a medium saucepan now. Scrape the bowl with a spatula so the measured cocoa and sugar are not left behind.
Heat gently. Set the saucepan over medium-low heat and warm the mixture for about 5 to 7 minutes, whisking frequently, especially around the bottom and corners of the pan. The hot chocolate is ready when it is steaming, evenly colored, and hot to the touch on the outside of the pan. Avoid letting it reach a rolling boil: boiling can create a skin, make milk foam over, or leave a scorched flavor. If it heats too quickly, lower the burner.
Finish and serve. Remove the pan from the heat and whisk in the vanilla. Taste carefully; if you prefer a sweeter mug, stir in a little more sugar while the drink is hot so it dissolves. Divide between two mugs and add marshmallows, whipped cream, or cinnamon if you like. Serve while warm.

Tips

Whisk the paste before adding the full amount of milk. Cocoa powder does not dissolve as readily as sugar, and pouring a large amount of liquid over dry cocoa can leave stubborn floating clumps. Mixing in a small amount of milk first gives you a smooth base. If a few lumps remain, whisk briskly while the drink warms or strain it through a fine-mesh sieve before serving.
Choose the milk for the texture you want. Whole milk makes a fuller, creamier drink. For a lighter result, use 2% milk; unsweetened oat milk or soy milk can also be used in the same 2-cup (480 ml) quantity. Plant milks vary in sweetness and thickness, so taste before adding extra sugar. Almond milk tends to make a thinner, more lightly flavored mug.
Keep the heat moderate. Do not leave the pan unattended once the milk starts to warm. Whisking now and then helps prevent a film from forming and keeps cocoa from settling on the bottom. If you see a skin, whisk it back in or lift it off; if the base smells scorched, do not scrape the burnt layer into the drink.
Adjust the sweetness after heating. Cocoa brands and personal preferences differ, so the listed sugar makes a balanced starting point rather than an unchangeable rule. Add sugar in small increments and stir until dissolved. Adding a large amount at the beginning can make it difficult to judge the final sweetness, especially if you plan to top the mugs with marshmallows or sweetened whipped cream.

Serving Suggestions

Pour the drink into heat-safe mugs and add toppings just before serving. Mini marshmallows soften quickly against the hot surface, while whipped cream gives a cooler, creamy first sip. A light dusting of cinnamon adds a warm spice note; a small pinch is enough so it does not cover the cocoa flavor. For a simple finish, leave the mugs plain and let each person sweeten or top their own.

This cocoa pairs well with crisp cookies, shortbread, biscotti, or a slice of plain pound cake. For a more filling snack, serve it with toast, a warm muffin, or a buttery pastry. If the drink is part of a dessert spread, offer a few topping choices in small bowls rather than mixing everything into the saucepan. That makes it easier to accommodate guests who want a less sweet mug or who prefer no toppings.

For children or anyone sensitive to very hot drinks, let the mug stand briefly and check the temperature before serving. A smaller mug also gives the drink more room for toppings and helps prevent spills. If you are making several servings, keep the cocoa warm over the lowest burner setting and stir often; do not leave milk sitting warm for an extended period.

Variations

Make it dairy-free: Replace the whole milk with 2 cups (480 ml) of unsweetened oat milk, soy milk, or another plant milk. Oat milk is often naturally creamy, while soy milk has a more pronounced flavor and almond milk is thinner. Use an unsweetened version if you want to control the sugar, and warm it gently because plant milks can also develop a skin or separate if boiled.

Add a little spice: Whisk ⅛ teaspoon (about 0.3 g) ground cinnamon into the dry cocoa mixture, or add a tiny pinch of cayenne for gentle heat. Start small, particularly with cayenne, since its strength varies. A strip of orange zest can also steep in the warm drink for a few minutes; remove it before pouring so the citrus aroma stays subtle and the texture remains smooth.

Make it richer: Substitute ¼ cup (60 ml) of the milk with ¼ cup (60 ml) heavy cream. The result is thicker and more indulgent, so it may taste sweeter even without changing the sugar. Another option is to stir in 1 tablespoon (15 g) of finely chopped semisweet chocolate after taking the pan off the heat. Whisk until melted, then taste before adding more sugar.

Make a stronger cocoa flavor: Increase the cocoa to 2½ tablespoons (about 12.5 g) while keeping the milk at 2 cups (480 ml). The drink will taste more pronounced and slightly less sweet. If you make this adjustment, add sugar only after tasting; cocoa can vary, and toppings may add sweetness too. Do not add extra dry cocoa directly to a finished mug, since it is likely to clump.

Prepare one mug: Halve every ingredient, using 1 tablespoon (5 g) cocoa, 1 tablespoon (about 12.5 g) sugar, 1 cup (240 ml) milk, and ⅛ teaspoon (0.5 ml) vanilla. Make the paste in a small saucepan and warm it over low to medium-low heat, whisking frequently. The smaller quantity may heat a little faster, so watch for steam rather than relying only on the full-batch timing.

Storage and Reheating

Hot chocolate is best freshly made, but leftovers can be saved. Let the drink cool enough to handle, then transfer it to a clean, covered container and refrigerate it within 2 hours of cooking. Keep it refrigerated for 3 to 4 days. If toppings have already been added, remove marshmallows or whipped cream before storing when practical; they can become soggy or change texture.

To reheat, pour the amount you want into a small saucepan and warm it over low heat, whisking frequently until evenly hot. For food safety, reheat leftovers to 165°F (74°C), checking with a food thermometer, then serve promptly. Avoid boiling, which can scorch the milk or make the texture less pleasant. You can also use a microwave-safe mug, heating in short intervals and stirring between them so the edges do not become much hotter than the center. Do not reheat the same portion repeatedly; warm only what you plan to drink.

Separation after refrigeration is normal. Stir or whisk the cold drink before reheating, then whisk again as it warms. If it smells sour, has an unusual appearance, or has been left at room temperature for more than 2 hours, discard it rather than tasting it to decide whether it is still good. Freezing is generally not ideal because milk can separate and become grainy after thawing, though a frozen portion can be blended into a cold drink if the changed texture is acceptable.

Frequently Asked Questions

Can I use Hershey’s Special Dark cocoa?

Yes. Use the same 2 tablespoons (10 g) amount, then taste the finished drink before changing the sugar. Special Dark cocoa has a deeper, darker flavor than standard natural unsweetened cocoa, so the result may seem less bright and more intense. If you want a milder mug, use 1½ tablespoons (about 7.5 g) cocoa and keep the milk and other ingredients the same.

Can I make this with water instead of milk?

You can replace the 2 cups (480 ml) of milk with water, but the drink will be thinner and less creamy because milk contributes both body and a rounded flavor. A useful compromise is to replace only ½ cup (120 ml) of milk with water and keep the remaining 1½ cups (360 ml) as milk. If using all water, taste before serving; you may prefer a little extra sugar or a splash of milk in the mug.

Why is my hot chocolate grainy or lumpy?

Usually the cocoa was added to too much liquid at once, or the dry powder had clumps that were not broken up. Whisking cocoa with a small amount of milk first creates a smooth paste that is easier to blend into the rest. If the drink is already lumpy, whisk it vigorously over low heat or pass it through a fine-mesh sieve. Graininess can also come from scorched milk, which cannot be fixed by straining.

Can I make a larger batch for guests?

Yes. Multiply the ingredients evenly and use a saucepan large enough to leave room for whisking. For example, double the recipe for 4 servings: use 4 tablespoons (20 g) cocoa, 4 tablespoons (50 g) sugar, 4 cups (960 ml) milk, and ½ teaspoon (2 ml) vanilla. Warm it gently and allow a little more time for the larger volume to heat, stirring regularly. Add toppings to individual mugs rather than the batch.

Can I sweeten it with honey or maple syrup?

Either can be used, although each adds its own flavor and a little liquid. Start by replacing the 2 tablespoons (25 g) sugar with 1½ tablespoons (about 30 ml) honey or maple syrup, then taste and adjust. Whisk the sweetener into the smooth cocoa paste before adding the remaining milk. Honey has a distinct floral note, while maple syrup gives the drink a woodsy sweetness, so neither tastes exactly like the version made with granulated sugar.
