Step 2. Gradually add flour and baking powder to the wet mixture. Stir gently to avoid overmixing. The batter should be thick and smooth.
Step 3. Fold in the diced apples, ensuring they’re evenly distributed throughout the batter.
Step 4. Pour the batter into a greased 20cm cake tin. Arrange thin apple slices on top in a decorative pattern and sprinkle generously with brown sugar.
Step 5. Place the cake in a preheated oven at 180°C and bake for 50 minutes. Check for doneness using a toothpick. Let the cake cool before slicing. Serve it as is or with a dollop of whipped cream for extra indulgence.
