Preheat your oven to 375 degrees Fahrenheit
In a small saucepan melt your butter oven medium heat
In a medium to large bowl measure out your sourdough discard, then whisk in the melted butter
In a small bowl combine the flour, salt, pepper, garlic powder and cheese
Add the dry ingredients into the wet ingredients and mix until evenly incorporated, the dough should be slightly shaggy but relatively easy to work with
Line a sheet pan with parchment paper then lightly sprinkle the parchment with flour and transfer your dough onto the parchment
Sprinkle the dough lightly with flour and begin the gently roll out the dough, you will probably need to add flour to the surface of the dough and the rolling pin a few times while rolling out the dough
Roll it out until it is roughly 1/8 to 1/4 inch thick. Then using a sharp knife or pizza cutter cut the dough into roughly 1 by 1 inch squares
I then like to separate the squares slightly from each other for a more even cooking. Take a fork and stab each one with a fork to create holes
Bake the crackers for 7 minutes, take them out of the oven and flip them and then bake for 7 more minutes. They should be a nice golden brown. They might feel slightly soft when you take them out of the oven but will crisp up as they cool.
Allow them to cool on the sheet pan and enjoy!
Store them in an air tight container at room temperature
