Preheat air fryer or oven to 300℉ and prepare the airfryer basket or a baking sheet by greasing it or layering with a sheet of parchment paper.
In a large bowl, whisk together the almond butter, coconut oil, maple syrup and vanilla extract.
In a medium bowl, mix together the oats, almonds, walnuts, sunflower seeds, cinnamon and salt. Add this to the wet ingredients and stir until combined.
Pour the granola mixture into the air fryer basket or on the prepare baking sheet. Bake for 15-20 minutes, stirring halfway in between.
Allow the granola to cool until transferring it to an airtight container for storage. Enjoy on top of smoothie bowls, yogurt, and more!
