Start by mixing all the ingredients in a medium bowl with a wooden spoon or another spoon you want to use. The dough will be a little sticky, but not too sticky. So, add some additional flour if you need it. Once you have mixed them all you can, knead the dough for 2-3 minutes until it is smooth.
Cover the dough with plastic wrap and let it rest for 8-10 minutes.
Preheat oven to 425 degrees.
Place the dough between 2 pieces of parchment paper and roll out with a rolling pin until the dough is very thin- about 1/16-inch.
Remove the top sheet of parchment paper, then cut with a pizza cutter, bench knife, round cookie cutter, or pastry wheel into the shapes you want.
I leave my cut cracker dough on the bottom piece of parchment paper then carefully slide it onto your baking sheet. If you want to add more seeds or nuts to the top of the dough add them now and gently press them in. I also like to sprinkle the crackers with a little salt.
Move immediately to the preheated oven and bake for 15-25 minutes. The baking time will depend on the thickness of the dough.
Remove the baked crackers and let them cool on a cooling rack.
