Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a bowl, whisk together the egg (or flax egg), applesauce, vanilla, and oil until smooth.
Stir in oats, oat flour, baking powder, and cinnamon until combined, then fold in the chopped apple.
Scoop 2-3 tablespoons of batter per fritter onto the baking sheet and flatten slightly.
Brush or spray the tops with a little oil and bake for 16-20 minutes, until golden and set.
Let cool slightly before serving. Drizzle with glaze drizzle if desired or pair with yogurt to dip!
