In a bowl, combine coconut and almond flour along with vanilla, cinnamon, monk fruit sugar and cold butter.
Use your fingers to combine this into a coarse, crumbly mixture.
Place on a plastic sheet, top with another layer of plastic and roll into a ¼ inch thick sheet using a rolling pin.
Remove the top layer of plastic and cut 1 inch squares using a sharp knife. Poke holes in each of them using a fork.
In another bowl, combine the remaining monk fruit sweetener with cinnamon.
Sprinkle this mixture generously all over the sheet. Pop it in an oven preheated at 450°F for about 6-7 minutes or until they look slightly golden brown.
Get them out, allow them to cool down completely and then gently remove them from the sheet.
Use immediately or store in an airtight container at room temperature.
Notes
Work quickly with cold butter. If the mixture starts feeling greasy, chill it for 10 minutes before rolling.
Roll evenly to about ¼ inch so the squares bake at the same rate and don’t burn at the edges.
Watch the oven like a hawk during the last 1–2 minutes. At 450°F, the difference between 'perfectly golden and crisp' and 'too dark and bitter' happens fast.
Pull the tray when the edges are just turning golden, then let residual heat finish the job as it cools.
Let the cereal cool completely before lifting. It firms and crisps as it cools, and handling it warm can cause crumbling.
