Preheat the oven to 375 degrees.
Cut each tortilla into 6 triangles and place in a large bowl. Add in melted butter and toss to coat.
In a small bowl, combine white sugar & cinnamon. Add to tortillas and toss to coat well.
Arrange tortilla triangles on a baking sheet in a single layer. Bake 12-15 minutes, flipping halfway through until tortillas are golden brown.
