Preheat your oven to 350°F (175°C). Grease a standard loaf pan.

Cream together 1/2 cup butter and 1 cup sugar until light and fluffy, about 3-5 minutes.

Beat in the eggs one at a time, then mix in 1 teaspoon of vanilla extract.

Whisk together 2 cups flour, 1 tablespoon baking powder, and 1 teaspoon ground cinnamon. Gradually add this mix to the wet ingredients, alternating with 1 cup of milk.

Fold in 1 to 1.5 cups chopped apples until evenly distributed.

Pour half of the batter into the prepared loaf pan, sprinkle with brown sugar, then layer with the remaining batter.

Bake for 50-60 minutes until a toothpick comes out clean. The top should be golden brown.

Cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely.

For an optional glaze, mix 1 cup powdered sugar with 1-2 tablespoons of milk and drizzle over the cooled loaf.
