Preheat oven to 350°F (177°C). Spray a 9x5” loaf pan with non-stick cooking spray or grease with butter and flour, or line with parchment paper and set aside.

In a small mixing bowl, combine the brown sugar and cinnamon. Set aside.

In a mixing bowl, whisk together flour, baking powder, and salt.

In a second mixing bowl, whisk together eggs, sugar, sour cream, melted butter, and vanilla extract.

Add the dry ingredients to the wet ingredients and mix together with a spatula until just combined. Stir in chopped apples.

Pour ½ of the batter into prepared loaf pan. Sprinkle on ½ the cinnamon sugar topping over the bread. Top with remaining batter and use a knife to swirl the cinnamon sugar mixture throughout the bread and sprinkle on remaining topping.

Bake for 50-60 minutes until a toothpick inserted in the center of the bread comes out clean. Remove from the oven and allow the bread to cool completely in the pan set on a wire cooling rack.

Whisk together the glaze ingredients and drizzle over the cooled bread.
