- In a food processor, pulse 1 cup of the rolled oats into a powder. Set aside. 
- In the bowl of a stand mixer fitted with the paddle attachment, combine remaining 1 1/3 cups of oats, coconut flakes, tapioca flour, salt and brown sugar. Mix on low speed until everything is evenly combined. 
- Add in corn syrup or brown rice syrup and melted coconut oil to the mixture and mix again until everything is evenly incorporated. 
- Scoop out half of the cookie batter into an 8×4-inch loaf pan lined with parchment paper (or foil). Press down firmly to create an even layer. Sprinkle chocolate chips over top. 
- Scoop the remaining cookie batter over top and spread evenly. Sprinkle with remaining rolled oat powder and press down gently to flatten. 
- Place in the freezer for 2 hours until set. Cut into 9 bars or squares, store in an airtight container, and enjoy!
