Preheat the oven to 350°F.
In a medium bowl, whisk together the flour, cinnamon, salt and baking soda. Make a well in the center. Pour in the liquid sweetener, water, and your fat of choice. Stir until all of the ingredients are fully incorporated.
Transfer the dough to a sheet of parchment paper, and place another sheet on top. Use a rolling pin to roll out to be approximately 1 cm thick. Trim off rough edges so that you have an even rectangle. Slice the dough into your desired sizes. Prick the center of each cracker with a fork. Roll up scrap dough and repeat. Top with flaky salt if desired.
Bake the crackers at 350°F for about 15 minutes or until crunchy. Cool completely to room temperature on the baking sheet before transferring to an airtight container. Say thank you and enjoy.
