2 teaspoons ground cinnamon, divided
2 Granny Smith apples, peeled and chopped to ½-inch dice
½ cup butter, room temperature
⅔ cup granulated sugar
1-½ teaspoons pure vanilla extract
1-½ cups all-purpose flour
1-¾ teaspoons baking soda
½ cup + 1 tablespoon milk, divided
½ cup powdered sugar
In another bowl, combine the diced apples with the remaining half of the cinnamon; stir to blend and set aside.
Add the flour and baking soda mix to the butter mixture, and stir until well-blended.
Add the remaining batter to the pan, followed by the remaining apples and brown sugar mixture. Lightly press the apples into the batter and swirl the brown sugar between the apple chunks and into the batter.
While the bread cools, prepare the glaze. In a small bowl, combine the powdered sugar with the remaining 1 tablespoon of milk. Mix until smooth, and then drizzle over the cooled bread.
