01 - In a small saucepan over medium heat, whisk together almond milk, heavy cream, cocoa powder, and chopped dark chocolate until well combined.
02 - Stir continuously until the chocolate is completely melted and the mixture is smooth and steaming, about 3-4 minutes. Do not allow the mixture to boil.
03 - Add erythritol, vanilla extract, and sea salt. Whisk vigorously until the sweetener is fully dissolved and the hot chocolate reaches a creamy, uniform consistency.
04 - Taste the mixture and adjust sweetener amount if needed to achieve desired sweetness level.
05 - Pour the hot chocolate into pre-warmed mugs. Top with sugar-free whipped cream and shaved chocolate if desired. Serve immediately while hot.
