Use a tablespoon to dollop the melted chocolate onto the baking sheets, leaving at least 1” gap between each tablespoon. If the chocolate doesn’t flatten out on its own, tap the baking sheets onto the counter once or twice. Sprinkle or drizzle with your favorite toppings. Transfer the baking sheets into the fridge or freezer to harden – it takes about 20 minutes for the chocolate to harden.
