Follow these simple steps to create your Maple Glazed Apple Blondies:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and line a 9×13-inch baking pan with parchment paper for easy removal.
2. Mix Butter and Sugars: In a large bowl, combine the melted butter, brown sugar, and granulated sugar. Stir until well combined.
3. Add Eggs and Vanilla: Mix in the eggs one at a time, followed by the vanilla extract. Ensure everything is well blended.
4. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt.
5. Incorporate Dry and Wet Mixtures: Gradually add the dry ingredients to the butter mixture, mixing until just combined.
6. Fold in Apples: Gently fold in the diced apples until evenly distributed throughout the batter.
7. Pour into Pan: Pour the batter into the prepared baking pan, smoothing the top with a spatula.
8. Bake: Bake in the preheated oven for 25–30 minutes or until a toothpick inserted into the center comes out clean.
9. Cool Down: Remove from the oven and let cool in the pan for about 15 minutes before transferring to a wire rack to cool completely.
10. Prepare the Glaze: In a small bowl, whisk together powdered sugar, maple syrup, and milk (if needed) until smooth. Adjust the consistency by adding more syrup or powdered sugar as necessary.
11. Glaze the Blondies: Once cooled, drizzle the maple glaze over the blondies, allowing it to set before slicing.
