Nutmeg Feather Cake with Penuche Frosting

This is one of my favorite cakes, and somehow, every time I make it, I underestimate how quickly the frosting changes from too hot and liquidy to too chunky and un-spreadable. I finally jotted down a couple notes on the recipe for next time. Namely- the option to add cream in at the end if it's too thick needs to be rewritten as mandatory. Even if you start to spread it and it works just fine, by the time you get half way around, it is not the same consistency. Then you think if I add cream now, the frosting will have two distinct consistencies, I can't do that! So the game day decision is to just go with it as, after all, it is homemade (and it looks it)! Another note should be to double or at least 1.5x the frosting so it is easier to frost at will.
Hoping that I see those notes before jumping in again. The great news is that it always tastes wonderful. The smell and flavor are so nostalgic for me, I just love it!
