First off, heat up your oil to 375°F in a deep fryer or electric skillet.
In a big bowl, mix together flour, sugar, baking powder, and salt. Then pour in milk, beaten eggs, and oil; give it a good stir until everything's all blended.
Now toss in those chopped apples and make sure they're evenly mixed in.
Time to fry! Drop spoonfuls of batter into the hot oil, but go easy, don't overcrowd the fryer. Let them cook for about 5 minutes until they're golden brown all over.
Once they're done, scoop them out with a slotted spoon and let them hang out on a plate lined with paper towels to soak up any excess oil.
Last but not least, give those warm fritters a good toss in a bowl with the cinnamon sugar until they're nicely coated.
And that's it! Dive into your delicious Mom's Apple Fritters and savor the flavor!
