Yield: 20 crackers
Preheat the oven to 350ºF. Line a baking sheet with parchment or a silicone baking mat.
Form the scraps into a ball and roll into a rectangle 1/4 inch thick. Sprinkle with the Cheddar, chipotle powder and salt. Press the topping down with your hands. Cut into 2-inch squares with a pizza cutter and transfer to the prepared baking sheet.
Bake until the pastry is crisp and the cheese is melted, about 10 minutes.
