Step 1: Preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper.
Step 2: Cut each tortilla into 6-8 wedge shapes, like pizza slices. You can use a knife or a pizza cutter.
Step 3: In a small bowl, melt the unsalted butter. In another small bowl, combine the granulated sugar and ground cinnamon, mixing well.
Step 4: Arrange the tortilla wedges in a single layer on the prepared baking sheet, ensuring they don't overlap.
Step 5: Lightly brush each tortilla wedge with melted butter. Then, generously sprinkle the cinnamon sugar mixture over each buttered wedge. You can also toss the wedges in a bowl with butter and then with cinnamon sugar for a more even coating.
Step 6: Bake for 12-15 minutes, or until the crisps are golden brown and crispy. Keep a close eye on them as they can brown quickly.
Step 7: Remove from the oven and let them cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely. They will crisp up more as they cool.
