  1. This cake is meant to be moist and it will have a lot of crumbs, so i dont recommend layering with this one. 
  2. use good quality cocoa powder 
  3. Do not over bake the cake. A good 20 -25 mins is good. Do keep a check. 
  1. ganache can be set on the counter top. I would recommend this, as you can check the consistency you want. This will happen while the cake is being cooled.
  2. if the ganache gets to hard, pop it on a bowl/saucepan with simmering water. And adjust the consistency accordingly. 
  3. You can store the ganache in the freezer, it will hold up good for atleast 2 months.
