Brioche is a very rich eggy bread, in the fine line between bread and sweet yeast cake. This is not very sweet, but the texture us so rich, and full of rich butter flavot (but not greasy!), that you will find yourself ignoring all the calories, and eating one after the other.
You may think that the brioche dough may be time consuming and hard to make, but, in fact, the mixer does all of your hard work, and after one night in the fridge, the dough is very easy to work with.
The thing that may be time consuming is making the chocolate truffles, but you can easily replace them with easier fillings like jam or Nutella spread.
Note: The recipe does not call for any liquids except the yolks. When I made the dough it did not form into a ball, but remained crumbly. I added about 1\4 cup of water, until the dough was a little sticky. I suggest that you make the recipe as it is, and if you see that you need to add liquids, add them, but do it slowly, just until you get a dough at the right texture.
