Place all 'bar' ingredients into food processor and mix until well-combined.
Press mixture firmly into parchment-lined tray (approx 8x8).
Put in freezer for 15 minutes to harden.
Create a double-boiler with a glass or metal bowl sitting on top of a saucepan filled with a bit of water (don't let water touch bottom of bowl). Bring to a boil then reduce to simmer.
Add chocolate and coconut oil and slowly melt while stirring continuously.
Once melted, stir in maple syrup and remove from heat. Let sit for 5-10 minutes.
Pour chocolate mixture over hardened bars and spread evenly over the top.
Put back in freezer for 10 minutes; once hardened, cut into 16 square bars.
Store in air-tight container in fridge.
