Preheat your oven to 325°F (160°C).
In a large mixing bowl, whisk together the almond flour, oat fiber, cinnamon, baking soda, and xanthan gum until everything is well combined and free of lumps. Set this aside.
In a separate bowl, use a hand mixer to cream together the softened butter and both sweeteners (Brown Swerve and monk fruit/erythritol) until the mixture is smooth and light.
Add the egg and vanilla extract to the butter mixture, continuing to mix until fully incorporated.
Pour the wet mixture into the bowl with your dry ingredients. Mix gently with the hand mixer until just combined and a dough forms.
Place the dough onto a piece of parchment paper. Top with another piece of parchment paper and roll it out into a thin rectangular shape, about ¼ inch thick or slightly thinner for extra crispness.
Using a sharp knife or pizza cutter, cut the dough into your desired cracker shapes (rectangles or squares). You can re-roll any scraps to get more crackers!
Prick each cracker 3 times down the center with a fork to give them that classic graham cracker look. Gently move the cut crackers to a baking sheet, ensuring they are slightly spaced apart.
Bake for 18-20 minutes, or until the edges are lightly golden brown.
Remove from the oven and let them cool on the baking sheet for 10 minutes. Then, transfer them to a wire rack to cool completely at room temperature. They will become perfectly crispy as they cool!
