Line an 18 cm (7-inch) baking pan with parchment paper and preheat the oven to 180°C (350°F). This ensures easy removal and even baking.
Core and slice 2–3 medium-sized apples into 0.5 cm thick pieces. Consistent thickness is key for even cooking and creating the rose effect.
Toss the slices of apples with lemon juice, sugar, cinnamon, and melted butter. Mix until well-coated for a deliciously fragrant base.
Microwave the slices for 2–3 minutes until pliable. Check their softness by bending each slice—if it doesn’t crack, they’re ready.
Sift flour, baking powder, and a pinch of salt into a bowl, then mix thoroughly. This ensures a light, evenly baked cake.
Whisk eggs, sugar, and vanilla until smooth, then add melted butter. The creamy mixture sets the base for a flavorful batter.
Fold half the dry mixture into the wet, then add milk and the rest of the dry ingredients. Mix gently until just combined to avoid a dense texture.
Spread the batter evenly in the prepared pan. This provides a stable base for your apple arrangement.
Layer the apple slices from the outer edge inward, overlapping slightly and curving them near the center. Press gently to secure each slice in the batter.
Bake at 180°C (350°F) for 40 minutes, then let it cool before removing from the pan. Cool completely on a wire rack for the best texture.
Sprinkle it with powdered sugar for a lovely finish. Slice, serve, and enjoy this stunning and delicious dessert!
