In a medium skillet, pour oil to a depth of 1/2 inch; heat oil over medium heat. Add tortillas, 1 at a time, and fry, about 1 minute per side until golden. (Press tortilla down with a fork if it starts to puff up while frying.) Drain on paper towels.
In a small bowl, combine sugar and cinnamon. Sprinkle evenly over hot tortillas. Set aside to cool.
Transfer fried tortillas to a serving platter. Drizzle with Dulce de Leche, and top with grated Mexican chocolate and pumpkin seeds.
