Preheat oven to 350 degrees. Spray a 9x5 loaf pan with non-stick spray, or line with parchment paper and set aside.

Prepare apple mixture. Toss chopped apples with spices and sugar until evenly coated.

Prepare brown sugar mixture in a small bowl. Whisk together sugar and cinnamon.

Prepare the bread batter. In a medium bowl, whisk together the flour and baking powder.

In a large bowl, use an electric mixer and beat together the softened butter and sugar until smooth. Beat in the eggs one at a time, then mix in the vanilla. Add in the flour mixture and mix until blended. Add the yogurt and mix until smooth.

Pour half the batter into the prepared loaf pan. Spread half of the apple mixture and half of the brown sugar mixture over the top. Gently swirl, just a little bit, with a butter knife. Pour the remaining batter over the top. Spread the remaining apple mixture and brown sugar mixture over the batter, gently pressing it in to the batter, or swirl it just a little with a butter knife again.

Bake in preheated oven for approximately 55 to 60 minutes, or until a toothpick inserted in the center comes out clean. After removing from oven, let it rest for at least 15 minutes before removing it from loaf pan. Cool on wire rack for at least another 20 to 30 minutes.

To make the glaze, whisk together all of the ingredients until smooth. You can make it thicker by adding a little more sugar, or thinner by adding a little milk. When you're ready to serve the bread, just drizzle the glaze all over the loaf.
