Pre-heat the oven to 175℃ (350℉). Line and grease two 18cm pans (I used springform pans for easier removal).
Whisk the eggs and sugar together until the mixture becomes pale and light (about five minutes).
Combine the flour, baking powder and cardamom powder together.
Slowly add to your wet ingredients, just until incorporated.
Add the milk, and continue, again, just until everything is incorporated.
Pour evenly between the two pans, then bake in the lower part of the oven for around 20-25 minutes. The cake is ready when it bounces back, has started to pull away from the edges, and an inserted skewer comes out clean.
Remove from the oven, and allow to rest for ten minutes before removing the sides. Then allow to cool completely.
