Creating Sourdough Cheez Its is simple when you follow these steps:

1. Mix Ingredients: In a large mixing bowl, combine the sourdough starter, shredded cheddar cheese, and softened butter. Mix until well incorporated.

2. Add Dry Ingredients: Add the all-purpose flour, salt, cayenne pepper, garlic powder, and onion powder to the mixture. Stir until a rough dough forms.

3. Adjust Consistency: If the dough feels too dry, add cold water one tablespoon at a time until it comes together.

4. Chill the Dough: Wrap the dough in plastic wrap and refrigerate for at least 30 minutes. This helps the flavors meld and makes it easier to roll out.

5. Preheat Oven: Preheat your oven to 350°F (175°C) while the dough chills.

6. Roll Out Dough: On a lightly floured surface, roll out the chilled dough to about 1/8-inch thickness.

7. Cut into Shapes: Use a sharp knife or pizza cutter to cut the dough into squares or desired shapes. Place them on a baking sheet lined with parchment paper.

8. Bake: Bake in the preheated oven for 12-15 minutes or until the edges are golden brown. Keep an eye on them, as they can burn quickly.

9. Cool: Remove from the oven and let the Cheez Its cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.

10. Store: Once cooled, store your Sourdough Cheez Its in an airtight container to keep them fresh.
