Preheat oven to 170 degree C. Line a 15 cm round cake pan with parchment paper..make sure the sides of the parchment comes a little above the cake pan. Grease the parchment well with oil.

Now let's make the batter. Take chocolate and butter in a bowl and melt it in microwave or over a double boiler. Once it is melted set aside to cool a bit.

Now whip the eggs till it is fluffy and pale and really frothy.

Now add the egg mix to the chocolate in batches and fold very gently. Once it is mixed well.

Pour this into the prepared pan and bake for 30 to 45 mins. Untill the cake is risen and baked.

Remove it and let it cool little. The cake will deflate a little.

Now invert it and peel off the parchment.

Cool it, Slice and serve with ice cream.
