Creating these Apple Cinnamon Bites is straightforward if you follow the steps below:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, baking soda, ground cinnamon, and salt.
3. Cream Butter and Sugars: In a separate bowl, cream the softened butter, granulated sugar, and brown sugar until light and fluffy.
4. Add Egg and Vanilla: Beat in the egg and vanilla extract until well combined.
5. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
6. Fold in Apples and Nuts: Gently fold in the diced apples and chopped nuts (if using) until evenly distributed.
7. Scoop Batter: Using a tablespoon or cookie scoop, drop spoonfuls of the batter onto the prepared baking sheet, spacing them about 2 inches apart.
8. Bake: Place in the preheated oven and bake for 25-30 minutes, or until the edges are golden brown.
9. Cool: Remove from the oven and let the bites cool on the baking sheet for about 10 minutes before transferring them to a wire rack to cool completely.
