Step 1: In a large bowl, combine the unsweetened cocoa powder, granulated sugar, powdered sugar, and fine sea salt. Ensure all ingredients are measured accurately for the best balance.
Step 2: Whisk all the dry ingredients together thoroughly until they are well combined and there are no visible clumps. This ensures an even distribution of flavors in every scoop.
Step 3: For an extra smooth mix, sift the entire mixture through a fine-mesh sieve into another clean, dry bowl. Discard any large clumps that do not pass through the sieve.
Step 4: Transfer the finished Easy Homemade Hot Cocoa Mix to an airtight container, such as a large glass jar, and store in a cool, dry place. It will keep fresh for up to 6 months.
Step 5: To prepare a single serving, add 2-3 tablespoons of the hot cocoa mix to your favorite mug. Use 2 tablespoons for a milder taste or 3 for a richer, more intense chocolate flavor.
Step 6: Pour 8 ounces of hot water or hot milk (dairy or non-dairy) over the mix. Stir vigorously with a spoon until the mix is completely dissolved and smooth. Enjoy immediately with your favorite toppings!
