Sprinkle sparkling sugars onto the top of dough and gently press down. Let the sugar stick on it. Cut into approximately 3/8-inch-wide slices. Place slices 2 inches apart onto a parchment paper. Bake for approximately 1o minutes in the preheated oven. Check when the edges of cookies start to get a golden brown and then remove to a wire rack and let it completely cool down.
