Line a 9 x 9 baking pan with 2 long pieces of parchment paper, long enough to go up over the sides for easy removal.
Lightly spray with oil.
In a medium bowl, whisk together oat flour, baking powder, baking soda, salt and cinnamon.
In a large bowl, with a mixer cream together the butter and the sugar on medium speed.
Add the egg followed by the honey, applesauce and vanilla extract.
Working by hand, stir in the flour mixture and the oats until just combined and no streaks of flour remain; stir in the chocolate chips, raisins and nuts.
Spoon oats onto prepared baking dish, flattening to make even.
Bake for about 23-25 minutes, or until light brown at the edges. They will seem soft and undercooked, but once they cool they will set completely.
Cool completely on a wire rack then refrigerate before cutting.
This will help them hold together better.
To cut use a long serrated bread knife and cut in a sawing motion.
Notes
*use gluten-free oats if you are on a gluten free diet
