Preheat the Oven: Preheat your oven to 400°F (200°C) and grease a baking sheet with nonstick cooking spray.

Mix the Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, kosher salt, and ground cinnamon. Set aside.

Combine the Wet Ingredients: In a large bowl, whisk the melted butter and granulated sugar until well combined. Then, whisk in the egg, vanilla extract, and unsweetened applesauce until smooth.

Add Dry to Wet: Gradually add the dry ingredients to the wet ingredients, stirring just until combined. Be careful not to overmix.

Fold in the Apples: Gently fold in the finely diced apples, making sure they are evenly distributed throughout the batter.

Scoop the Batter: Using a tablespoon, scoop out portions of the batter and drop them onto the prepared baking sheet, spacing them a few inches apart.

Bake the Fritter Bites: Bake in the preheated oven for 10 minutes, until they begin to turn golden brown.

Broil to Caramelize the Glaze: Remove the bites from the oven and switch the oven to the broiler setting on high. Meanwhile, prepare the glaze.

Prepare the Apple Cider Glaze: In a small bowl, whisk together the powdered sugar and apple cider (or juice) until smooth and thin enough to drizzle.

Glaze and Broil: Brush a portion of the glaze over the warm fritter bites. Place the bites under the broiler for 2-4 minutes, rotating the baking sheet frequently. Broil until the glaze starts to bubble and caramelize, being careful not to burn.

Add More Glaze: Remove from the oven and brush the remaining glaze over the fritter bites. Let them sit for about 15 minutes to allow the glaze to set.

Serve: Once the glaze has hardened slightly, your Apple Fritter Bites are ready to serve. Enjoy them warm or at room temperature!
