Preheat oven to 300℉/150℃
Mix in a large bowl the almond flour, golden sweetener, cinnamon, baking soda, and salt.
Stir in large egg, melted butter, and vanilla extract until the dough comes together stiffly.
Transfer dough onto large piece of parchment paper, and add to the top another large piece of parchment paper. Roll out the dough under the parchment paper until it's 1/4 inch thick.
Use a pizza cutter or knife to cut dough into size of graham cracker you wish. Prick the graham crackers using a fork to make divvy marks where to break crackers once baked.
Transfer crackers onto baking sheet and bake for 20-25* minutes until they start to brown and get firm. (*Ovens vary)
Remove from oven and let cool for 10 minutes on baking sheet, then transfer to a cooling rack.
