Bolo de nozes (Walnut Cake)

The walnut cake filled and covered with Egg Yolk Sweet ("ovos moles") is a traditional Portuguese Christmas Cake, introduced to Brazil. There are several versions of this recipe, that can also be filled with Egg Yolks Threads or with "papo de anjo" (sweet baked egg yolks), and usually are covered with whipped cream. It's a great cake with a unique and unmistakable flavor, for special occasions. 
The large-scale commercial nut production (pecans and macadamia) started in the second half of the 20th century, in some areas of the south and southeast of the country. Until then there were only the common walnut (Juglans regia), imported and very expensive, used primarily for very important parties.
