Line a 9"x9" baking pan with parchment paper and set aside.
In a large mixing bowl, add the oats, dried cranberries, dates, nuts, and chia seeds. Stir to combine.
In a small saucepan, add the almond butter, honey, sea salt, and cinnamon. Heat over low, stirring just until the ingredients are combined and the almond butter has melted.
Pour the almond butter mixture into the oat mixture and stir to coat and combine.
Spoon the mixture into the prepared baking pan and press to pack the mixture evenly into the pan.
Chill pan in the fridge for 1-2 hours, or until firm. Pan may also be chilled in freezer for about 10-15 minutes.
Once chilled, remove from pan. Use your hands to form mixture into small balls.
In small saucepan - or in microwave in 30 second intervals - melt chocolate over low heat until smooth.
Use a fork to dip granola balls into chocolate. Once coated, place on parchment paper. Chill in fridge until chocolate is set.
If desired, sprinkle sea salt on top. Place granola bites in fridge to set.
Once chocolate is set, store granola bites in airtight container in fridge.
