Preheat oven to 180C. Grease baking trays or line with baking paper.
In a large bowl, stir together the brown sugar, oats, flour, bicarb soda, baking powder, salt and cinnamon. Make a well in the center and pour in the canola oil, minced prunes, water, egg whites and vanilla. Mix until well blended. Stir in the raisins, walnuts and apricots.
Scoop biscuits using an ice cream scoop, or roll into golf ball sized balls. Place biscuits 5cm apart onto the prepared baking trays and flatten with wet hands. These biscuits do not flatten very much while baking.
In the preheated oven, bake 8 minutes for chewy biscuits 10 to 12 minutes for dry biscuits. Biscuits will not get crisp. Remove from baking trays to cool on wire racks.
