Preheat oven to 350 degrees. Use a 9x5-inch loaf pan and spray with non-stick cooking spray.

Mix ⅓ cup brown sugar and 1 teaspoon cinnamon together in a bowl. Set aside.

Whisk together 1 ½ cups flour and 1 ¾ teaspoon baking powder in a bowl. Set aside.

In another bowl, beat ⅔ cup sugar and ½ cup softened butter until creamy.

Add 2 eggs, one at a time, blending well. Stir in 1 ½ teaspoon vanilla extract.

Gradually mix in the flour mixture, followed by ½ cup milk, until smooth.

Toss chopped apples with 2 tablespoons granulated sugar and 1 teaspoon cinnamon in a bowl.

Pour half the apple bread batter into the prepared loaf pan and spread out, then top with half the chopped apple mix.

Sprinkle ½ of the brown sugar/cinnamon mixture on top.

Repeat: Pour the remaining apple bread batter into the prepared loaf pan and top with remaining chopped apple mixture.

Sprinkle the remaining brown sugar/cinnamon mixture on top.

Use a knife to swirl through the mixture a few times.

Bake in the preheated oven until a toothpick inserted in the center comes out clean, approximately 60 minutes.

To make glaze, mix ½ cup powdered sugar and 1 to 3 tablespoons milk or cream together until well mixed.

Let loaf rest in pan for about 15 minutes before removing from pan to cool on a cooling rack. Drizzle with glaze.

If you want more glaze, make a double batch.
