Instructions:

Prepare the Apple Filling: In a medium bowl, mix together the chopped apples, granulated sugar, and cinnamon. Stir until the apples are well-coated. Set aside to allow the flavors to meld together while you prepare the bread batter.

Make the Bread Batter:

1. Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan or line it with parchment paper.
2. In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
3. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
4. In a separate bowl, whisk together the flour and baking powder. Gradually add the flour mixture to the wet ingredients, alternating with the milk, beginning and ending with the flour mixture. Mix until just combined, being careful not to overmix.

Assemble the Bread:

1. Pour half of the batter into the prepared loaf pan and spread it evenly.
2. Add half of the apple mixture on top of the batter, gently pressing it into the batter.
3. Sprinkle the cinnamon sugar swirl mixture over the apples.
4. Pour the remaining batter over the apple layer, then top with the remaining apples, pressing them gently into the batter.

Bake the Bread:

1. Place the loaf pan in the preheated oven and bake for 55-60 minutes, or until a toothpick inserted into the center comes out clean. If the top of the bread starts to brown too quickly, you can tent it with aluminum foil for the last 10-15 minutes of baking.
2. Once baked, remove the bread from the oven and allow it to cool in the pan for about 15 minutes. Then, transfer it to a wire rack to cool completely.
