Break the frozen dark chocolate and white chocolate into small chunks and add them to a food processor. Pulse the chocolate until you have fine chocolate crumbs (3-4 minutes). Note: for this step to work, the chocolate needs to be frozen for at least 24 hours. Otherwise, it will melt in the food processor.
In a bowl, add and mix the processed chocolate, white sugar, cocoa powder, corn starch, salt, ground cinnamon, and milk powder.
Transfer the hot chocolate mix into a mason jar. This mix makes 24 cups of gluten-free hot chocolate.
Preparing a cup of Hot Chocolate
Heat a cup of milk in a medium-sized saucepan over low-medium heat until the milk starts to simmer (3-4 minutes). Then, add two tablespoons of hot chocolate mix and whisk it in. Once the chocolate is completely melted (2-3 minutes), pour the gluten free hot chocolate in a cup and enjoy.
Notes
Processing the chocolate: For the chocolate to be processed into fine crumbs, it needs to be frozen for at least 24 hours. This prevents the chocolate from melting in the food processor. For this step, I used my Braun 4-in1 Food processor.
Storage: The hot chocolate mix can be stored in a mason jar at room temperature for up to six months, ensuring that the milk powder used has at least a year before it expires.
