Line a cookie sheet with parchment paper.
In a medium bowl, combine almond flour, pepper, salt and baking powder and whisk until smooth.
Add basil, cayenne, and garlic and stir until evenly combined.
Next, add in the pesto and whisk until the dough forms into coarse crumbs.
Cut the butter into the cracker mixture with a fork or your fingers until the dough forms into a ball.
Transfer the dough onto the prepared cookie sheet and spread out the dough thinly until it’s about 1 ½ mm thick.
