Prepare the apples by peeling and chopping them into small pieces. Toss in a bowl with light brown sugar, ground cinnamon, and ground ginger.
In another bowl, whisk together the egg, white granulated sugar, vegetable oil, sour cream, and vanilla extract until smooth.
Combine all-purpose flour, baking soda, and kosher salt in a separate bowl and whisk together.
Gradually add the dry ingredients to the wet mixture while stirring gently until just combined. Fold in the prepared apple mixture gently.
Preheat your oven to 350°F (175°C) and grease a loaf pan. Pour in the batter and bake for about 55 minutes or until a toothpick comes out clean.
Prepare the glaze by mixing sifted powdered sugar with vanilla extract and milk until smooth. Drizzle over the warm bread.
Once cooled completely, slice into pieces and enjoy.
