Cover inside of the pan with a parchment paper.

Have your ingredients at room temperature.

Preheat the oven to 160℃ for 15 min.

Whip up eggs and sugar and vanilla for 5 min with high speed, next add oil and milk and just mix them. Then turn off the device.

After mixing wheat flour, baking powder, and cocoa powder, sift them for 2 or 3 times. Sifting lets air go through the flour mixture. It makes your cake softer.

Now mix everything using a wooden spoon. Try to move your hand in one direction, if clockwise, maintain.

Pour the mixture into your baking tin

Bake for 30 minutes until a toothpick comes out clean.

Cool the pan for 15 minutes. Then remove the cake and cool it completely.

You can now design with chocolate, frosting, etc.

Cake is ready to serve. Enjoy!
