This recipe is from 100 Days of Real Food. I made a few small tweaks and wanted to make note of them somewhere for my own future reference -- but the recipe comes from her awesome website. I also doubled her recipe -- because apparently you can store any "extras" in the freezer for later.
2 cups whole wheat flour
10 Tablespoons cold butter, cut into tablespoon size chunks
8 oz or 3 cups grated sharp cheddar cheese
1/4 tsp paprika
A pinch of garlic powder
1/4 tsp salt
Sea salt for sprinkling
Preheat oven to 325 degrees. Combine all ingredients in a food processor or stand mixer and mix. The mixture will eventually turn into a big ball of dough, but be patient because it can take a few minutes to get to that point.
Roll the ball into a log about 1 1/2" in diameter. At this point you could refrigerate the dough until later. With a sharp knife slice 1/4" thick pieces off the log and place each one flat on an ungreased baking sheet. Try to rotate which side you are cutting down on because the top of the log does start to flatten a little.
Lay them out on a baking sheet, trying not to let the dough pieces touch each other. Poke centers of crackers with a toothpick or fork (optional). Sprinkle with sea salt (optional). Bake for 8-10 minutes.
