Chocolate chips melt into a rich milk-and-cream base. Stirring still matters: a slow cooker can scorch milk or chocolate, and its holding temperature needs checking.

Crockpot Hot Chocolate

  • 6 US cups whole milk
  • Two 12-fluid-ounce cans evaporated milk (3 US cups total), not sweetened condensed milk
  • 2 US cups heavy cream
  • 2 teaspoons vanilla extract
  • 3 US cups semisweet chocolate chips
  1. Combine all ingredients in a clean 6-quart slow cooker. Follow the appliance fill guidance and leave room to stir.
  2. Cover and cook on low for about 3 to 4 hours. Whisk thoroughly every 20 minutes in the first hour and periodically afterward, scraping the bottom. Heat until all chocolate is melted and the stirred mixture is at least 140 F (60 C); time varies by appliance.
  3. Ladle into mugs. For buffet service, use a setting that actually maintains at least 140 F throughout the stirred batch and check with a food thermometer; the warm label alone is not a guarantee. Stir before serving.
  4. For leftovers, divide promptly into shallow heat-safe containers and refrigerate within 2 hours, or 1 hour above 90 F. Store at 40 F or below for up to 3 days. Reheat only needed portions on the stove or in the microwave to 165 F (74 C), stirring and checking temperature; do not use a slow cooker to reheat cold leftovers.

Yield: 15 small portions; measure finished batch and divide equally. Time: 5 minutes preparation plus 3 to 4 hours heating.

Yield, Equipment and Batch Math

The milk and cream alone total 11 cups; melted chocolate increases the finished volume. The source labels this 15 servings without a measured mug size. Measure the finished batch and divide into 15 equal small portions rather than promising 15 full eight-ounce mugs. Use two separate 6-quart cookers for a double batch. A half batch uses 3 cups milk, one 12-fluid-ounce can evaporated milk, 1 cup cream, 1 teaspoon vanilla and 1 1/2 cups chips. Follow the smaller cooker’s minimum/maximum fill guidance; check earlier, and use the same temperature endpoint instead of promising unchanged cooking time.

Chocolate, Milk and Toppings

Replace all 3 cups chips with the same measured volume of milk-chocolate or dark-chocolate chips if preferred; sweetness changes. Finely chopped chocolate can be used by equal package weight to the chips you replace, not by an assumed chip-to-bar volume conversion. For extra chocolate body add 1/2 cup chips and whisk until melted; finished yield grows. For a thinner drink add milk in measured 1/4-cup increments and recheck holding temperature. Cocoa is a suspension, not something that dissolves like sugar; cocoa alone is not an equal-volume replacement for chips. For a cocoa-only drink, use a separate cocoa recipe.

For the richer source option replace 3 of the 6 cups milk with 3 cups half-and-half. For a dairy-free house version use 6 cups oat or cashew beverage, 3 cups unsweetened evaporated coconut milk (not condensed coconut milk), 2 cups coconut cream, 2 teaspoons vanilla and 3 cups labeled dairy-free chips. Whisk as above; texture and heating differ, and the temperature/storage rules still apply.

Keep toppings out of the stored batch. Per mug choose 2 tablespoons mini marshmallows, 2 tablespoons purchased whipped cream, 1 teaspoon crushed peppermint candy, 1 teaspoon caramel or dulce de leche, 1 teaspoon chocolate shavings or cocoa nibs, or 1/8 teaspoon ground cinnamon. An optional 1-fluid-ounce freshly brewed espresso makes a mocha; an adult-only 1-fluid-ounce liqueur or bourbon addition changes portion size and adds alcohol. Place cinnamon sticks beside the mugs rather than inside drinks. Keep dairy toppings chilled.

Make Ahead, Stovetop and Troubleshooting

Combine the milk, evaporated milk, cream and vanilla up to 24 hours ahead in a covered refrigerated container, then add chips when heating. Cold ingredients may need longer; do not promise an extra fixed 30 minutes. For the stovetop branch use a large heavy saucepan over medium-low heat, whisk frequently until melted and at least 140 F, usually 15 to 25 minutes; avoid boiling. Keep checking hot holding temperature. Graininess can reflect chocolate formulation, poor dispersion or overheating; whisking may improve it but cannot undo scorching. Discard burned mixtures rather than covering the taste.

Keep fresh milk, fruit and finished drinks at 40 F (4 C) or below. Cool heated mixtures promptly in shallow heat-safe containers or an ice-water bath, then refrigerate within 2 hours; use a 1-hour limit above 90 F (32 C). Discard perishables left without temperature control beyond those limits. Follow purchased ingredient labels if shorter. A normal smell does not establish safety.
