Preheat and Prepare:
Preheat your oven to 350°F (175°C). Grease and line a 9-inch springform pan with parchment paper.

Prepare the Apples:
Peel and core the apples, then slice them as thinly as possible (use a mandoline if available). Set aside.

Make the Batter:

• In a large bowl, whisk together the eggs and sugar until pale and frothy.
• Stir in the milk, melted butter, and vanilla extract.
• Sift in the flour, baking powder, and salt. Whisk until smooth and lump-free.

Combine Apples and Batter:

• Add the thinly sliced apples to the batter, ensuring every slice is well-coated.

Assemble and Bake:

• Pour the apple mixture into the prepared pan, arranging the slices evenly.
• Gently press down to compact the layers.
• Bake for 50-60 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.

Cool and Serve:

• Let the cake cool in the pan for 10 minutes before transferring it to a wire rack.
• Dust with powdered sugar before serving.
