Preheat your oven to 375°F (190°C) and prepare a 9-inch springform pan by buttering and dusting it with flour.

In a mixing bowl, whisk together the room temperature eggs until frothy, then gradually add the granulated sugar, whisking until thick and light.

Incorporate the melted butter, vanilla extract, cardamom, flour, and salt, mixing until just combined.

Slice the apples and layer them in the prepared pan, dotting with butter and sprinkling with brown sugar and cinnamon.

Pour the batter over the arranged apples, smoothing it out with a spatula to ensure even coverage.

Bake in the preheated oven for 35-40 minutes until golden brown on top and the edges slightly pull away from the pan.

Remove from oven, let cool in the pan for 20 minutes before carefully removing the sides of the springform pan.
