In a food processor, add flour, butter, cheddar cheese, cayenne pepper, and paprika. Process until the mixture looks like crumbs.
Add water and process until dough forms a ball.
Shape dough into a circle with your hands. Wrap in plastic wrap and refrigerate for at least 45 minutes until very cold.
Place dough on a lightly floured surface. Roll out to ⅛-inch thickness. Sprinkle with salt.
Use a pizza cutter to cut into ½-inch squares. If desired, poke a small hole in the center of each square with a skewer.
Place squares on an ungreased baking sheet. Bake at 350°F for 15–20 minutes until golden and crisp.
Transfer crackers to a cooling rack. Once cooled, store in an airtight container.
Notes
Ingredient Substitutions
Cheese
Try sharp white cheddar, pepper jack, or a cheddar blend for different flavors.
Seasoning
Swap cayenne for chili powder if you want less heat. Smoked paprika can add depth.
How to Store and Reheat
Store cooled crackers in an airtight container at room temperature for up to one week. If they soften, place them on a baking sheet and reheat at 300°F for 3–5 minutes to crisp them again.
