Preheat your oven to 375°F (190°C) and prepare a baking sheet with parchment paper.
In a large bowl, whisk together flour, baking powder, sugar, cinnamon, and salt.
Dice the apples into small chunks and toss them with a little flour to prevent sinking.
In another bowl, beat the egg and mix in milk and melted butter until well combined.
Pour the wet mixture into the dry ingredients and fold gently; then add the diced apples.
Spoon batter onto the prepared baking sheet, leaving space between each fritter.
Bake for 15-20 minutes until golden brown; let cool slightly before serving.
