In a large mixing bowl, combine flour, baking powder and sugar.
In a medium bowl, whisk together egg, Benecol®, milk and water.
Gently add the wet ingredients to the dry ingredients and fold in blueberries.
On a floured work surface, turn out the dough and pat down to a round disk approximately 1" thick by 10" wide, and slice into 8 wedges.
Place onto a floured baking sheet and bake for 10-15 minutes or until golden brown.
OPTIONAL: Make an egg wash by combining 1 egg with 2 tablespoons of milk and whisking, and brush the top of the scone dough just before baking. This will give the scones a beautiful golden color when they come out of the oven!
