Directions
- 1
Wash and dice the apples into small cubes — peeling is optional.
- 2
Add the apple cubes, eggs, sugar, oil, cinnamon and salt to a blender. Blend until completely smooth.
- 3
Pour in the oat flour and blend again until a uniform batter forms.
- 4
Add the baking powder and fold it in gently with a spatula — do not over-mix.

Pour the batter into a greased and oat-flour-dusted cake tin.
- 6
Oven method: bake at 350 °F (180 °C) for about 30 minutes. Air fryer method: preheat to 350 °F (180 °C) and cook for 20–25 minutes.
- 7
Test doneness by inserting a toothpick into the centre — it should come out clean.
- 8
Allow to cool completely before unmoulding. Finish with a dusting of cinnamon and serve.
💡 Chef's Tip
Use very ripe apples for a naturally sweeter, softer cake. Swap the sugar for maple syrup if preferred. The cake keeps well wrapped at room temperature for up to 3 days, or refrigerated for 5 days.
