👨🍳 How to Make It (Step-by-step)
Step 1: Make the Apple Purée
Blend 2 chopped apples until smooth and creamy.
💡 Use sweet apples like Gala or Fuji for best flavour.
Step 2: Combine with Eggs
In a mixing bowl, whisk the apple purée with 2 eggs until fully combined.
💡 Room temperature eggs blend better and rise more evenly.
Step 3: Prepare the Oat Flour
Blend 1 cup (100 g) of oat flakes into a fine flour.
💡 Use a high-speed blender for a smooth flour-like texture.
Step 4: Mix the Batter
Add the oat flour and 1 tsp baking powder to the apple-egg mixture. Mix well.
💡 Let it rest 5 minutes — oats will absorb the moisture for a better texture.
Step 5: Add Flavour (Optional)
Stir in a pinch of vanillin sugar or cinnamon for warmth.
💡 Cinnamon or cardamom work beautifully here.
Step 6: Prepare the Cake Tin
Grease a round 8-inch (20 cm) baking pan or line it with parchment.
💡 Use coconut oil or spray for easy release.
Step 7: Pour and Smooth
Pour the batter into the tin and smooth the top evenly.
💡 Tap the pan gently to remove air bubbles.
Step 8: Bake the Cake
Bake at 180°C (350°F) for 25–30 minutes until golden and set.
💡 Toothpick test: it should come out clean.
Step 9: Prepare the Topping
Melt 30 g sugar-free white chocolate and mix it with 1½ tbsp of yoghurt until smooth.
💡 Use Greek yoghurt for a creamy finish.
Step 10: Assemble and Decorate
Spread the topping over the cooled cake and sprinkle 30 g ground almonds.
💡 Let it set in the fridge for clean slices.

🎯 Common Mistakes to Avoid
🎯 Using tart apples — they may not provide enough sweetness or moisture.
🎯 Overmixing the batter — it can lead to a dense, rubbery texture.
🎯 Skipping the parchment — the cake may stick and break apart.
🎯 Using cold eggs — they won’t blend properly and affect rise.
🎯 Not blending oats finely — coarse oats affect structure and mouthfeel.
🎯 Baking at too high a temperature — it can burn the edges before the centre sets.
🎯 Cutting the cake while hot — it crumbles and loses shape.
🎯 Forgetting to rest the batter — oats won’t hydrate properly.
🎯 Adding the topping too early — it may melt or sink into the cake.
🎯 Storing uncovered — the cake dries out and loses its softness.
