Combine brown sugar and cinnamon in a small bowl and stir to combine. Set aside.

Remove the peel from the apple and chop into small pieces. Place in bowl and set aside.

Combine softened butter and sugar in a large bowl and combine on low/med using a hand or stand mixer. This will be grainy and chunky.

To the same large bowl add the eggs and vanilla extract. Continue to mix on low/med using the mixer. This will be soupy and no large chunks should remain.

Next add the flour, baking powder and salt into the bowl with the rest of ingredients and stir to combine. Lastly, add the milk and continue to stir with a spoon until incorporated.

In a greased 9x5 inch loaf pan add half the batter then top with half of the chopped apples, followed by half of the brown sugar mixture. Repeat this layering one more time using the remaining ingredients.

Place the apple bread in the oven on the center rack at 350 degrees F for 50-55 minutes or until an inserted toothpick comes out clean. Once finished let stand in the pan for 10 minutes then remove, slice and enjoy warm on its own or with butter.
