In a food processor, combine the almond flour, shredded cheddar cheese, and water. Optionally, add 1/8 teaspoon salt. Blend until well combined.
Squish together to form a dough. Place the dough on a sheet of parchment paper.
Roll out the dough to about 1/4 inch thickness using a rolling pin. It may be easier to place a sheet on top of the dough and roll it out between two sheets of parchment paper.
Use a pizza cutter or knife to cut the dough into cracker-sized pieces.
Use a toothpick or the end of a utensil to poke a hole in the center of each cracker.
Carefully transfer the parchment paper with the crackers onto the baking sheet, making sure to separate them so they don’t touch. Optionally, sprinkle a little salt on top of the crackers.
Bake in the preheated oven for 12-13 minutes, or until the crackers are crispy.
