1. Preheat the oven to 375°F (190°C). Line an 8 inches (20cm) springform tin with baking parchment and grease lightly. Set aside.

2. Add the butter and sugar to a large bowl and mix until light and fluffy. Add the eggs, one at a time, and mix until well combined. Combine flour, baking powder, baking soda, Salt, cinnamon, and cardamom and add to the large bowl – mix until just combined. Transfer the batter to the prepared springform tin and spread out into one even layer.

3. Peel the apples, quarter, and core. Use a fork to scratch lines into the apples and press the apple pieces into the batter. Bake the cake for about 60-75 minutes or until a wooden skewer inserted into the center of the cake comes out clean. Take out of the oven and let cool down for a moment, then brush with some warmed apricot jam and sprinkle with some additional sugar. Let cool down a bit further before serving.
