The problem with most hot chocolate recipes is that they are too sweet. This recipe has the perfect balance of rich chocolate flavor and sweetness.

Using a slow cooker is the perfect way to make a large batch of hot chocolate. If you need a stovetop version try my homemade hot chocolate.  

Slow Cooker Hot Chocolate Ingredients

You can use any milk to make this slow cooker hot cocoa recipe, but whole milk will help make it creamy. This recipe uses no cream. Instead, I used evaporated milk. 

  • some milk
  • evaporated milk
  • a few semi-sweet chocolate chips
  • unsweetened cocoa
  • brown sugar
  • pure vanilla extract
  • cornstarch
  • toppings: like some whipped cream, mini marshmallows, and chocolate shavings

How to Make Slow Cooker Hot Chocolate

Warm 4 cups of milk a bit in the microwave or stove. Do not boil; only until it is a bit warm.

Pour into your Crockpot or slow cooker with the cocoa powder, and whisk until it’s mostly combined; this might take a while. The cocoa won’t be completely combined until the milk is hot inside the slow cooker.

Add the remaining sugar, evaporated milk, chocolate chips, and vanilla. Mix and cover the slow cooker.

How to make thick hot chocolate

Add a bit more cornstarch, about 1/4 teaspoon more for extra thick hot chocolate. I find this texture very nice. It’s not quite thick, but it’s also not too liquid. 

Can milk be used in a slow cooker?

Yes, milk can be used in a slow cooker. Usually, you add milk at the end to prevent curdling. With this slow cooker hot chocolate recipe, you can add it at the beginning and stay smooth.
