Made this last night - was fantastic! Easy to make and fast to bake. Resisted my usual compulsion to throw in chocolate chips, and it was still amazing! The delicious cake is now, sadly, long gone and just a fond memory. Thanks for the recipe! Will make again.

if you wanted to modify this recipe to include less than the full amount of sugar (i'm ok with some sugar!) how might you adjust it? would you need to substitute anything else if you only included, say, 1/3 C of sugar, instead of 2/3? has anyone tried substituting stevia for sugar in cake recipes? many thanks in advance for any helpful advice.

Thanks - it's 1 cup of all-purpose. I keep trying to edit the recipe, but it's not showing up for some reason.

Love, love, love this cake! I also always put a fresh piece of banana on the cake top before I serve it. Has anyone ever made cupcakes with this recipe? Also, I assume after frosting the cake, you always refrigerate because of the cream?

honestly, we never have leftovers to refrigerate, but yes, I would suggest you chill any leftovers. be sure to wrap the pan well because the frosting will pick up any off flavors from your fridge. <br />
