Add the oil, sugar, milk, nesquick and cocoa in a blender

Mix until smooth

Separate half the mixture into a large bowl and keep the other half in the blender
One half will become the sauce, and the other will be the cake itself

To the half in the blender add the egg, vanilla, flour and baking powder

Mix until smooth and place in a pyrex tray

Place the tray in the oven for 25-35 min at a temperature of 180°C

Right after removing the cake from the oven, dump the sauce half on the cake while still hot

Wait for 10-15 min for the cake to cool down, then serve and enjoy
