In a bowl whisk the eggs, yogurt, milk, cream and vegetable oil until you get an homogeneous batter.

Add the sugar and mix.

Add the sifted the flour, sugar, cocoa powder, and baking soda.

Stir until batter is just blended.

Pour in your buttered mold.

Bake 40 minutes. Check baking with a knife: insert into the center, if it comes out clean it's baked. If not, bake another 1 or 2 minutes.

Cool in the mold for 10 minutes before removing to cool completely on a grid.

If you want, melt the chocolate with a double-boiler.

Let cool down a bit (35 C / 95 F degrees) and pour on the cake.
