Preheat your oven to 180 C (350 F). Grease a loaf pan with butter and set aside.
In a small bowl, mix together the brown sugar and cinnamon and set aside.
In another bowl, mix together the flour and baking powder, set aside.
In a mixing bowl, cream together the white sugar and butter. Use an electric mixer or the reliable hand and elbow grease ;)
Beat in the eggs one at a time, add the vanilla and mix that in as well. Add the flour mixture and mix in then mix in the milk to make a smooth batter.
Pour half of the batter into your prepared loaf pan than add 1/2 of the chopped apples and 1/2 of the brown sugar and cinnamon mixture, lightly tap the apples into the batter.
Pour on the remaining batter, then the remaining apples, and the remaining brown sugar and cinnamon mixture. Lightly tap the apples into the batter.
Using a butter knife, make a couple of swirls through the batter.
Bake for 30 to 40 minutes or until a toothpick (wood skewer would be a better choice) comes out clean.
Remove from oven and let cool on a rack for 20 minutes, then roll out to cool on a rack. When cooled, slice and enjoy :)
