In a medium saucepan, whisk together the coconut milk, cocoa powder, powdered Erythritol, vanilla extract, and salt over medium heat until well combined and smooth.
Remove the saucepan from the heat and let it cool to room temperature.
Pour the mixture into a blender and blend until smooth.
Pour the mixture into popsicle molds, leaving a little space at the top for expansion.
Insert popsicle sticks into the molds and freeze for at least 4 hours or until the popsicles are firm.
To remove the popsicles from the molds, run them under warm water for a few seconds to loosen them.
Serve immediately or store in the freezer in an airtight container for up to 1 month.
