Arrange an oven rack to 400°F and mist a baking sheet with nonstick cooking spray.
Stir together the flour, baking powder, salt, and cinnamon in a medium-sized basin.
Beat the sugar and melted butter together well in a big basin. Whisk in the applesauce, vanilla, and egg until smooth.
Stirring just until mixed, add the dry ingredients to the wet ones. Fold in the diced apples rather gently.
To the prepared baking sheet, scoop out 1 tablespoon quantities of batter and place them a few inches apart.
After ten minutes of baking, take out of oven and set broiler to high.
To make the glaze, beat the powdered sugar and apple juice or cider until it is pourable.
Let some of the glaze run down the edges of the heated fritter bits as you brush over them. Broil, turning the pan often, for two to four minutes, or until the glaze begins to boil and caramelize.
Take out of the oven and liberally coat the fritters' tops with the remaining glaze.
Give the glaze fifteen minutes to set before serving.
ENJOY!
