Top with the remaining batter, smoothing it out into a single layer. Add the reserved handful of apples and the rest of the cinnamon sugar mixture. Again, use the butter knife to create swirls through the batter.

Bake in the oven for 50-55 minutes or until a toothpick inserted in the middle comes out clean.

Let the bread cool on a wire rack for 10-20 minutes.

While cooling, prepare the glaze. Whisk sifted icing sugar with hot water until the desired consistency is reached. Spoon or drizzle the glaze over the top of the loaf. Allow the glaze to set for 5-10 minutes before slicing.
