Add the peanut butter, coconut oil, maple syrup, and chocolate chips to a saucepan over medium heat. Stir frequently, until all ingredients are well mixed and melted.

Add in vanilla and salt and mix to combine.

Add in oats and turn the heat down to low. Continue to stir until the mixture is thick and cohesive and the oats soften slightly. If it still seems too wet, add more oats.

Remove from heat. Place heaping spoonfuls of the mixture onto a greased baking sheet, using the back of the spoon to shape into round, cookie shapes.

Place in the refrigerator to harden for at least 30 minutes. Keep stored in the refrigerator.
