You really need to let this one cool down in order to pick up on any background flavours. I don’t get any classic eggnog spices from this (was hoping for some nutmeg), but I do pick up on a super light, creamy vanilla eggy note. It’s more like vanilla soufflé than cake. Or, I once tried making one of those mug cakes in the microwave and it ended up tasting really eggy. This sort of captures that type of dessert.
