Preheat the oven to 400°F (200°C). Lightly coat a large baking sheet with nonstick cooking spray.

In a medium bowl, whisk together the flour, baking powder, kosher salt, and cinnamon until evenly combined.

Pour the melted butter into a large mixing bowl. Whisk in the granulated sugar, followed by the egg.

Stir in the alcohol-free vanilla extract and applesauce until smooth.

Add the dry ingredients to the wet mixture. Stir just until no dry streaks remain, taking care not to overmix.

Gently fold in the finely diced Honeycrisp apples until evenly distributed.

Scoop approximately 1 tablespoon of batter for each fritter and arrange the mounds a few inches apart on the prepared baking sheet.

Bake the Apple Fritter Bites for 10 minutes. Remove the baking sheet from the oven and switch the broiler to high.

Meanwhile, make the glaze by whisking the powdered sugar and apple cider or apple juice together until smooth. The glaze should be fairly thin and easy to brush.

Brush a layer of glaze over each warm fritter, allowing some to drip naturally down the sides.

Return the baking sheet to the oven and broil for 2–4 minutes, rotating the pan every minute for even caramelization. Watch carefully because the sugary glaze can brown very quickly.

Remove the fritters as soon as their tops are lightly caramelized.

Brush the remaining glaze over the warm fritter bites.

Allow them to rest on the baking sheet for approximately 15 minutes, or until the glaze has set.
