In a large bowl, whisk together almond flour, brown sugar, cinnamon, baking powder, and salt.
Stir in the egg, melted butter, and vanilla extract until dough comes together. You might need a wooden spoon as the dough will be firm.
Turn the dough out onto a large piece of parchment paper. Top with another piece of parchment paper. Roll out the dough as evenly as possible to about ¼ to ⅛ inch thickness. The dough should measure roughly 12” x 10”.
Remove top piece of parchment paper and use a sharp knife or a pizza wheel to score into 6 pieces across and 4 pieces down. The crackers should measure about 2 inches. Transfer the entire piece of parchment onto a baking sheet.
Bake 25 to 30 minutes, until just beginning to brown and firm up. Remove crackers and prick each warm cracker, in 3 rows, with the tines of a fork.
Use the pizza cutter and cut again through the slice marks. Crackers will break up. Let cool completely and enjoy.
Notes
Swerve sweetener can be used in place of the brown sugar.
Roll the dough out on a piece of parchment paper so they transfer easily to the baking sheet.
Use a pizza slicer for slicing each cracker.
Cooling time is important for the crackers to get nice and crispy.
