Combine cocoa powder, sugar, oil, milk and condensed milk and stir on low heat. Don't let it boil. Once the sugar dissolved, leave it to cool.

Sift the flour with baking soda and baking powder.

Lightly beat 3 eggs.

Mix the eggs into the cocoa mixture. Then add vanilla extract.

Fold the flour into the cocoa mixture, bit by bit, till combined.

Pour the mixture into your baking pan and steam the cake for about 1hour to 1hour 10mins. Good luck! 😚✌🏻
