Toppings are very customizable. You can get creative with it. To give it a more festive feel, add some colorful mukhwaas to the chocolate mix. Use nuts, M&Ms, edible flowers, shaved chocolate, sprinkles, seeds, dried fruits, candies, and/or pretzels. To make it nut-free, use pepitas and/or sunflower seeds. When selecting toppings, keep in mind the color contrast, textures, and flavors it will add to this dessert. Feel free to add as little or more when garnishing the bark.
