Start by making cranberry chia filling. In medium saucepan, stir together cranberries, water, maple syrup, and 1/2 tsp (2 mL) cinnamon over medium heat. Stir mixture often until cranberries start to bust open, about 5 minutes. Using spoon or fork, mash cranberries until mixture is chunky with no whole cranberries remaining. Remove mixture from heat and stir in vanilla extract and chia seeds. Set aside.
