In a saucepan, combine the milk, heavy cream, and sugar. Heat over medium heat until the sugar is completely dissolved, but do not bring to a boil.
Add the cocoa powder and chopped dark chocolate. Stir continuously until the chocolate is melted and smooth.
Stir in the cayenne pepper or chili powder, mixing well to ensure the flavors are evenly distributed.
Remove the saucepan from the heat and stir in the vanilla extract.
Allow the mixture to cool completely to room temperature, then refrigerate for at least 2 hours to chill thoroughly.
Pour the chilled ice cream base into an ice cream maker and churn according to the manufacturer's instructions. If you don't have an ice cream maker, pour the mixture into a freezer-safe container and stir with a fork every hour to prevent ice crystals from forming.
Place the ice cream in the freezer for at least 4 hours to firm up completely.
Before serving, let it stand at room temperature for a few minutes to soften slightly for easier scooping. Garnish with a sprinkle of grated chocolate or chili powder, if desired.
