Preheat oven to 350 degrees F.

Combine the flours, maple syrup, egg, oil, baking soda, and salt in a mixing bowl. Stir until a dough forms, and fold in the blueberries.

Transfer the mixture to a clean surface, and form into a 3-inch thick circle. Cut into wedges and transfer to a parchment lined baking sheet.

Sprinkle with the maple sugar and bake until gold brown, 15-18 minutes.
