In a large bowl, add the flour, sugar, baking powder, salt and cinnamon and stir to combine.
Now add the applesauce and soy milk to the bowl with the dry ingredients and mix until just combined. Do not over mix. Fold in the diced apples.
Heat 2 inches of oil in a large, heavy skillet or pot to about 375 degrees (you do need a thermometer). Scoop 1/3 cup of the apple fritter batter and place in the hot oil, spreading it down to flatten quite a bit. You can also first flatten them on a floured surface, then transfer carefully to the pot for frying.
Cook on one side for about 2-3 minutes until golden brown, then flip with tongs and cook another 1-2 minutes until browned.
Place the cooked fritters on a cooling rack with a pan or parchment paper underneath to catch any oil drippings, as well as to catch glaze later.
Continue with all the batter until you have used it all, then turn off the heat.
Make the glaze: Whisk the glaze ingredients together in a small-medium sized bowl until smooth, then dunk each fritter into it. Place back on rack to harden and drip. Wait a few minutes if possible for the glaze to harden before enjoying.
