Chocolate cake - Sjokoladekake

Ingredients: 
- 120g of chocolate powder; 
- 4 eggs; 
- 2 tea cups of flour; 
- 2 tea-cups of sugar (brown sugar is better); 
- 1/2 tea-cup of olive oil; 
- 1 dessert spoon of baking soda; 
- 1 tea-cup to warm milk; 
- 1 package of cream (100 mL); 
- 150 to 200 grams of dark chocolate. 

Recipe:
Mix while adding the ingredients by the following order: first the chocolate powder, then the sugar, baking soda, the flour, beaten eggs, milk and olive oil. The mixture seems too liquid, but no problem, just put it in the oven and heat up to 180 degrees Celsius. Leave it there for 50 minutes tops.
Now it is time to prepare the covering of the cake. Heat the cream on a stove until it starts to boil. Immediately add the chocolate broken into small pieces. Blend the hot cream and chocolate until the chocolate melts, and cover the cake with it (obviously, wait until the cake is ready). For the perfect flavor, the cake has to be placed in the refrigerator and eaten cold.
Sometimes I add an extra layer in the middle of the cake, adding either nuts or almonds. In the photo I also invented a cream of white chocolate (using the same technique as previously done with dark chocolate).
