In a large pot, melt almond butter, honey and coconut oil (if using) over medium-heat until the mixture comes to a boil, stirring constantly. Lower the heat and simmer until the mixture is slightly thickened, about 2 minutes. Remove the pot. (At this point, you can add vanilla, cinnamon and salt, if using).
Fold in oats, shredded coconut, and chopped almonds. reserving the whole almonds for topping.
Transfer the mixture into the prepared pan while pressing down very firmly and flattening with a spatula until tight and compressed. Press the reserved whole almonds down into the bars, evenly spaced apart. Press in some chocolate chips or any other add-ins of your choice.
Press down with spatula one more time so everything is nicely packed and compact. Place the pan in the freezer (or fridge) until hardened, about 1 hour. When the bars are set, use the parchment paper to lift them from the pan. Slice into even bars.
*can also use 1/2 cup of almond flour or oat flour instead of the 2/3 cup of chopped almonds
Bars are best enjoyed cooled straight from the fridge or freezer. When warmed they don't hold together as well.
