Part 3/6:

1. Mixing Dry Ingredients: Pour the blended mixture into a bowl and sift in the flour, along with baking powder and bicarbonate of soda. The latter is optional, though it helps achieve a darker cake. Add corn starch to enhance the cake's softness. If you don't have corn starch, you can replace it with an equal amount of flour.

2. Gentle Incorporation: Carefully mix the ingredients until the batter is smooth and well combined.

Baking the Cake

1. Prepare the Baking Pan: Lightly grease a 20x30 cm (8x12 inch) baking pan with a non-stick spray, oil, or butter and flour, ensuring you don’t over-grease it since the cake won't need to be unmolded.
