Preheat your oven to 350°F (175°C) and grease and line a baking pan with parchment paper.

Peel, core, and thinly slice your apples, tossing them with lemon juice to prevent browning.

In a mixing bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and cardamom.

In another bowl, combine the melted butter, sugar, eggs, vanilla, and yogurt and mix until smooth.

Gradually add the dry mix to the wet ingredients, stirring gently until just combined.

Spread half of the batter into the prepared pan and layer half the apple slices on top.

Add dollops of remaining batter and layer the rest of the apple slices on top.

Mix the topping sugar and cinnamon, then sprinkle over the apple slices.

Bake for 40–45 minutes until the top is golden and a toothpick comes out clean.

Let the cake cool in the pan for 10–15 minutes before transferring to a wire rack.
