Add almonds, coconut and salt (if using) to a large bowl. Stir until well mixed. Pour maple syrup over this mixture. Fold until well incorporated.
Pour this mixture into the prepared baking pan. Using a rubber spatula, press down on mixture and smooth into a tightly-packed, even layer. Bake for 28-38 minutes (mine took 33 mins). Bars must bake thoroughly, or they won’t hold together when cooled.
Allow to cool for 1 hour (or until completely cooled), in the pan on a cooling rack. Pinching opposite ends of the parchment paper lining, lift bars out of pan. Gently peel parchment paper off the bottom of the bars. Slice into 12 bars (6 rows by 2 columns). Enjoy! Storing instructions below.
