Preheat the oven to 400F (205C) degrees. Line a rimmed sheet pan with foil. Lay the strips of bacon on the pan in a single layer. Bake for 18 minutes. Remove from the oven. Drain the bacon on a paper towel-lined plate and save 1/3 cup (55 grams) of the drippings for the glaze. Dice the bacon.
Heat the milk in the microwave for 1 minute. In a large bowl, whisk together the eggs and sugar. Add in the milk. Using a wooden spoon, stir in the flour, baking powder, salt and cinnamon.
Add the diced apples and diced bacon.
Heat the vegetable oil in a large skillet over medium heat to 325-350F (160-175C) degrees. Drop a large spoonful of batter into the hot oil. Use another spoon to scrape the batter off of the first spoon and gently flatten the fritter out into the oil. Add 2 to 3 fritters to the pan at a time. Fry for 3 minutes.
Flip and fry for 3 more minutes.
Place a baking rack over a sheet pan. Remove the fritters from the oil and let drain on the rack while you continue cooking the rest of the batter.
In a small bowl, whisk together the bacon drippings, milk and powdered sugar. For a grown-up fritter, add a tablespoon of bourbon.
Spoon the glaze over the fritters. Flip and glaze the other side. Serve.
