Preheat oven to 350 while you combine and mix all ingredients in a small bowl.
Using a silicon spatula, spread small amounts at a time out on a parchment paper-lined baking sheet. Make sure to create a thin and even layer across the sheet to get the perfect crispy texture for your crackers.
Bake for 10 minutes before removing to divide crackers into small squares by firmly pressing the edge of a bench scraper into the dough in a grid pattern. You can also use a chopstick to create a hole in the center of each small square to help get an even crispy texture. Sprinkle with flaky sea salt and press it in gently.
Bake for an additional 10-20 minutes, until crackers are browned and crispy. Let cool before separating the cracker squares.
