Preheat oven to 350. Place parchment paper in a 8x8 or a rectangle pan. Mix together the shortbread ingredients and then place in the pan. Bake for 10 minutes or until crust is golden brown. Allow to cool for 10 minutes (or just place in freezer!)
Make the chocolate sauce by melting cocoa powder and coconut oil over low until fully incorporated. Pour chocolate over caramel layer and allow to cool until firm in the freezer about 30 minutes. You'll want to make sure the chocolate isn't too hard so it's easy to cut. Or just flip the bars upside down so the shortbread crust is the top layer and then cut into desired square sizes! Serve right away or store in the freezer for snacking later :)
