In a large mixing bowl, whisk together 1 cup of whole milk, 1 large egg, ½ cup of granulated sugar, and 1 teaspoon of vanilla extract until smooth.

In a separate bowl, mix together 1½ cups of all-purpose flour, 2 teaspoons of baking powder, ½ teaspoon of salt, and 1 teaspoon of ground cinnamon.

Gently fold the dry ingredients into the wet batter, then add in 1 large diced apple and stir until just incorporated.

In a deep skillet, heat about 2 inches of vegetable oil to 350°F (175°C).

Using a ¼-cup measuring cup, drop spoonfuls of batter into the hot oil, frying about 3-4 fritters at a time for 2-3 minutes on each side.

Once golden and crisp, use a slotted spoon to remove the fritters from the oil and place them on a plate lined with paper towels.

In a small bowl, whisk together 1 cup of powdered sugar, 2 tablespoons of milk, and ½ teaspoon of vanilla extract until smooth.

While warm, dip the fritters into the glaze or drizzle it generously over the top.
