Exquisite cake to make at home and it only takes 5 minutes

To begin, preheat the oven to 180°C.
In a large bowl, beat the eggs and sugar until well combined.
Add the milk and vegetable oil, and mix until smooth.
Gradually add the flour and baking powder, mixing well after each addition, until smooth.

Divide the dough into two equal parts.
In a separate bowl, mix the cocoa and water until smooth.
Add the cocoa paste to one half of the dough and mix until completely incorporated.
In a previously buttered mold, pour half of the batter without cocoa and spread it evenly.
Pour the other half of the batter (with cocoa) on the white batter and spread it evenly.

Using a fork, create a swirl effect by passing the fork through both batters.
