Preheat the oven to 350F.
Toss the blueberries with the cornstarch, then pour the coated berries into a 2-quart glass or ceramic baking dish.
Pour ¼ cup real maple syrup over the blueberries in the baking dish. Set aside.
In a medium mixing bowl, combine the ingredients for the crisp topping. Note: If you love the flavor of coconut but find the long shreds annoying, pulse the shredded coconut in a food processor before adding to the Crisp Topping mixture.
Sprinkle all of the topping mixture evenly over the blueberries.
Bake at 350F for 30-40 minutes, until the topping is golden brown and the blueberries are juicy and bubbling around the edges of the dish.
Cool slightly before serving. Top with a scoop of vanilla ice cream or whipped cream, as desired.
