Preheat the oven to 350F. Line a 11 x 7 pan with parchment paper or foil and spray with cooking spray. Leave an overhang on the sides to make it easier to remove the bars from the baking pan.

For the apple filling

In a pan on low to medium heat add the apples, brown sugar, butter, vanilla and cinnamon. Cook for 4-5 minutes to soften a little. Remove from heat and allow the apples to cool completely.

For the bars

In a stand mixture fitted with a paddle attachment, cream the butter until light and fluffy. Add the brown sugar and granulated sugar and mix until combined. Stop the mixer and with a spatula scrape the bottom and the sides of the bowl to incorporate the butter.

Then add the eggs one at a time, beat well after each addition.

Add the salt and vanilla, mix well.

In a medium bowl mix the dry ingredients, flour, baking powder, cinnamon and nutmeg together. Add the wet ingredients and stir the mixture until combined.

Add the cooled apple mixture and mix gently.

Using a spatula or your hands spread the batter evenly in the prepared pan.The batter is very sticky so it might be a little hard to spread. You can spray your clean hands with cooking spray to help spread the batter evenly in the pan.

Bake the bars in a preheated oven for 30-40 minutes or until the bars are golden brown and a skewer comes out clean. Baking time may vary depending upon your oven and how big you made your apple chunks.

Remove the pan from the oven and let cool on a wire rack. Once the bars are cooled spread with the vanilla glaze.

To make the glaze add the softened butter, cinnamon and the sifted powder sugar to a small bowl, mix well. This will make a paste, then add the milk or heavy cream and vanilla extract to get the glaze to the consistency that you like.

Pour the glaze on the blondies and use an off set spatula to spread evenly on the bars. Let sit for 20 minutes to set, then slice and enjoy the fruits of your labor.
