Firstly, mill the wheat to get your freshly milled flour.
Also, get your pan preheated with the oil ready. We used enough peanut oil to fill the pan about 1&1/2 to 2 inches high. Then, preheated it to 375*F. This can take up to 20 minutes to preheat, so get it started early in the process.
Then, add the sugar, baking powder, salt, and cinnamon to the bowl of freshly milled flour. Stir to combine.
In a separate small bowl, add the milk, eggs, and applesauce. Stir to combine.
Pour the wet ingredients into the dry ingredients, and mix just until combined. Then, fold the peeled & diced apples into the batter.
Prepare a baking sheet with some paper towels. (This is where the fritters will go to drain after frying.)
Using a high heat digital thermometer, check the oil and make sure it is up to temperature before frying the fritters. (If the oil is too hot, it will burn the outside before the inside is cooked, if the oil is too cold, it will make the fritters very oily and odd textured.)
Once the oil is up to temperature, drop about 1/4 cup of batter into the oil, and lightly press to flatten a bit. (I like to use a metal measuring cup, so it can touch the oil.)
Cook each side until golden brown, about 2 minutes per side. Make sure not to overcrowd the pan, because that will drop your oil temperature resulting in an uneven cook.
Remove fritter from the oil onto some paper towels to drain. Let the oil come back up to temperature, and repeat with the rest of the apple fritters until gone.
Make the glaze. So, add milk to the powdered sugar in a clean bowl. Whisk together, then add vanilla and whisk that in. You may need to add more milk if the glaze is too thick, or more powdered sugar if it is too thin. You are looking for the glaze to coat the back of the spoon, but still drizzle excess off.
Let the fritters cool a few minutes, then while still a bit warm dunk each side of the fritter into the glaze. I like to place a cooling rack over my paper towel lined baking sheet for an easier glaze cleanup.
Once both sides of the fritter are coated, let the excess drain off, then place on the cooling rack. More glaze should drizzle off.
Let the apple fritters cool and dry completely, the glaze will harder as it dries.
