- Whisk together the flour, baking powder, salt, cinnamon, and nutmeg in a separate bowl.
- Gently fold in the finely diced apple with a spatula.
- Spread the batter into the prepared baking pan, creating an even layer.
- Mix together the sugar and cinnamon for the topping and sprinkle it evenly over the batter.

- Let the bars cool completely in the pan before lifting out and slicing into squares.

Notes
Check for doneness at the lower baking time to avoid overbaking. Use a room temperature egg for better incorporation into the batter. Store bars in an airtight container at room temperature for up to 5 days.
