After you obtain a homogeneous cake mixture, pour it into a suitable buttered and sprinkled with flour form.
Place the form in a preheated 356°F (180 °C) oven to bake about 30-35 min.
Once the cake cools, pour the warm glaze over it. To make it, melt the crumbled chocolate in a water bath with the butter and oil. You have to obtain a homogeneous mixture.
I used the same recipe for the cake in the 2nd photo, except instead of cocoa I added 5 tbsp coconut flakes.
