1. Preheat oven to 350F.

Make Jam:

1. Combine blueberries and maple syrup together in a small sauce pan over medium heat.  Keep over heat until its reduced and  you can break up blueberries and it becomes more sauce-like.
2. Remove from heat, stir in chia seeds, and put in fridge while you make crust to allow it to thicken (NOTE: you can also make this a day ahead to let it thicken even more!)

Make Crust:

1. Combine crust ingredients together in a large mixing bowl an stir until combined and a dough forms.
2. Roll the dough flat between two pieces of parchment paper, as thin as you can without it breaking.
3. Cut into rectangle pieces (2 for one bar, 4 for two bars, etc)
4. Scoop a spoonful of jam into the center of one rectangle of dough, and then top with another rectangle.
5. Using a fork, press edges shut.
6. Bake for 30 minutes.

Optional glaze on top:

1. Combine extra jam filling with powdered sugar and cashew milk.  Start with measurements above and adjust based on how thick or thin you want it to be.  Drizzle on top!
