Yes, deb...both of those will be okay. And if you want to ensure a moist
cake, brush the layers with a heavy Simple Syrup before icing. Per Alice Medrich, Goddess of Chocolate: 2 C sugar to 1 C water, boil for 4 minutes.
The ONLY cake I've screwed up by putting it in the refrigerator was a Puerto Rican version with a meringue icing (not the Swiss or Italian or French meringues...just whipped egg whites and sugar). It looked fine going in...came out looking pocked. Bummer.
