Preheat oven to 350 degrees
Place the blueberries, dates, and prunes in a saucepan and turn the heat on low, keep it low, don't add water.
In a mixing bowl combine the applesauce, oil, egg, vinegar, vanilla, maple syrup, and mix well.
Add the millet, almond flour, arrowroot flour, xanthan gum and oats. Combine until well mixed and divide the dough into halves.
Place half of the dough into a 9x9 inch pan and set the rest aside until the blueberry filling is in place.
In a bullet blender with the flat blade blend the blueberry mixture and spread it evenly over the dough.
Place the remaining dough over the filling. You can roll this out and place it over the filling or just make little balls and drop them over the filling. They will bake together to form a crust.
Place in the oven for 20 minutes.
Let cool and cut into bars. It makes 9 servings.
