Preheat your oven to 200°C (400°F) and line a baking sheet with parchment paper.

In a large mixing bowl, whisk together the flour, sugar, baking powder, cinnamon, and salt.

In a separate bowl, beat the egg, then stir in the milk and vanilla extract until well combined.

Pour the wet mixture into the dry ingredients and stir gently until just combined.

Gently fold in the diced apples until evenly distributed in the batter.

Heat about 1 inch of vegetable oil in a large skillet over medium heat.

Drop spoonfuls of the batter into the skillet and fry for 2-3 minutes on each side until golden brown.

Transfer the fritters to the prepared baking sheet and bake for 10-12 minutes.

Allow the fritters to cool slightly on a wire rack, then dust with powdered sugar before serving.
