Preheat the oven to 180°C.
If using homemade taco dough, roll it into two thin tortilla shapes.
Mix the Sugar and Cinnamon powder together in a small bowl.
Brush one side of each tortilla with the melted Butter.
Sprinkle evenly with the cinnamon sugar.
Cut each tortilla into triangles and arrange on a lined baking tray.
Bake for 8 minutes, or until crisp and lightly golden.
