Place the cocoa powder and maple syrup in a small saucepan with 2 tablespoons of the plant-based milk.

Whisk the ingredients into a smooth paste to prevent clumping.

Add the remaining plant-based milk and place the saucepan over medium heat.

Whisk continuously until the mixture is hot and steaming, ensuring it does not reach a rolling boil.

Remove from heat and stir in the vanilla extract and sea salt.

Pour into a mug and serve warm.
