Step 1: Prepare the Apples
- Heat a large skillet over medium heat and melt the butter.
- Add the thinly sliced apples, sugar, and cinnamon (if using). Sauté for about 5–7 minutes until the apples are soft and slightly caramelized.
- Remove from heat, stir in vanilla extract, and set aside to cool.
Step 2: Make the Cake Batter
- Preheat your oven to 350°F (175°C) and grease a 9-inch (23cm) springform pan. Line the bottom with parchment paper.
- In a mixing bowl, beat the eggs and sugar until pale and frothy.
- Add vanilla extract and milk, mixing until combined.
- In a separate bowl, sift together the flour, baking powder, and salt.
- Gradually fold the dry ingredients into the wet mixture until just combined. Do not overmix.
- Pour the batter into the prepared pan and spread evenly.
Step 3: Add Apples and Bake
- Arrange the sautéed apple slices evenly over the batter.
- Bake in the preheated oven for 25 minutes or until the cake is lightly set.
Step 4: Prepare the Custard Topping
- While the cake bakes, whisk together the egg, heavy cream, sugar, and vanilla extract in a bowl until smooth.
Step 5: Add the Custard and Finish Baking
- Remove the cake from the oven after 25 minutes and pour the custard mixture evenly over the top.
- Return the cake to the oven and bake for an additional 20–25 minutes, or until the custard is set and lightly golden.
Step 6: Cool and Serve
- Allow the cake to cool in the pan for 10–15 minutes before removing the springform ring.
- Serve slightly warm or at room temperature. Dust with powdered sugar or serve with whipped cream or vanilla ice cream for an extra treat.
Tips:
- Apple Variety: Use tart apples like Granny Smith for contrast or sweeter apples like Honeycrisp for a mild flavor.
- Make-Ahead: This cake can be stored in the refrigerator for up to 2 days. Reheat slightly before serving for the best texture.
- Optional Add-ins: Add a splash of Calvados or rum to the custard mixture for a boozy twist.
