Crockpot Hot Chocolate

Bahan-bahan (6 porsi)

• 3 cups whole milk (must be whole for the best texture!)
• 1 cup half-and-half (or heavy cream if you want to make this outrageously decadent)
• 6 ounces dark or bittersweet chocolate*
• 3 tablespoons granulated sugar
• 1 tablespoon unsweetened cocoa powder or Dutch process cocoa powder
• 2 teaspoons pure vanilla extract
• 1 teaspoon instant espresso powder or coffee powder (optional for a more intense flavor)
• Pinch kosher salt
• Toppings of choice: marshmallows (whipped cream, a drizzle of caramel, a handful of extra chocolate chips)
