How to Make Halloween Hot Chocolate

The first step to making your hot chocolate for Halloween is gathering your ingredients. To prepare the drink, you will combine your dry ingredients and wet ingredients in your slow cooker.

Start by whisking together the unsweetened cocoa powder, salt, and sugar in a large bowl. Whisk the ingredients slowly and carefully to prevent the cocoa powder from creating a mess on your countertop.

Cocoa powder doesn’t mix well with cold ingredients, so to prevent clumps of cocoa in your hot chocolate, it’s a good idea to premix the powder with some warm milk. Heat one cup of milk in the microwave until it’s bubbling (around 2 minutes), then pour the milk into the bowl with your cocoa powder mixture. Carefully whisk the warm milk into the chocolate until it’s smooth and well combined.

Pour the remaining cold milk and heavy cream into your slow cooker. Add the cocoa powder mixture and whisk until the chocolate is fully mixed into the milk and cream, making sure to break up any leftover clumps of chocolate.

Set the slow cooker to cook on low for four hours or high for two hours. Every so often, remove the lid from the slow cooker and stir the ingredients together to prevent a film from forming on the top of the cocoa as it warms up.

When you’re ready to serve your hot chocolate, add the purple food coloring. I used an entire tube of purple gel food coloring to get this bright color. But you can adjust the amount of food coloring you add to your recipe to get your desired shade.

Halloween Hot Chocolate Ideas

Once you have your Halloween hot chocolate prepared, the fun begins! Make sure your guests have plenty of toppings to choose from to decorate their cups of cocoa at your party.

Use your Halloween cocoa to create a fun hot chocolate bar at your Halloween party! These topping ideas are perfect for decorating a spooky witch-themed cup of hot chocolate:

  • Mini marshmallows. You can use traditional mini marshmallows for your cocoa or add some color to your hot chocolate with the help of orange and green mini marshmallows. I separated those colors out of a bag of fruit-flavored marshmallows to decorate the top of my hot chocolate.
  • Halloween sprinkles. You can’t go wrong with sprinkles at a party! Dress up your Halloween hot chocolate with the help of holiday-themed sprinkles in popular colors like orange, black, and purple.
  • Whipped cream. Make sure your guests have some whipped cream to top their cocoa. You can use canned whipped cream or make your own homemade recipe to offer your guests. If you make your own, try adding some food coloring to give it more of a Halloween look.
  • Chocolate pieces. Add to the chocolate flavor of your Halloween hot chocolate with the help of chocolate pieces. Chocolate shavings or mini chocolate chips make a great topping for hot cocoa.
  • Halloween candy. There’s plenty of candy options available during thos holiday. Why not offer some Halloween candy as a topping option on your Halloween hot chocolate bar?
  • Meringue ghosts. Since the flavor of meringue is similar to marshmallows, these easy cookies make a great option for hot cocoa toppings. Make some meringue ghosts for your guests to add to the top of their hot chocolate.
