Wrap the tofu in a cloth and remove as much moisture as possible.
Add black sesame powder and sugar into a bowl and mix well.
Sift the cake flour and baking powder, then add them to the black sesame mixture.
Mash the tofu into a creamy texture, then mix evenly with the cooking oil and eggs.
Add the dry ingredients into the tofu mixture and combine with a spatula.
Pour the batter into a pound cake mold and smooth out the top.
Bake in a preheated oven at 180°C for 35-40 minutes.
After cooling, remove from the mold and cut into appropriate sizes.
