Starbucks Lemon Loaf Cake

Starbucks Lemon Loaf Cake it has a very pronounced lemony flavor, super moist, fluffy yet dense, almost bread pudding-like consistency and a delicious white glaze. I have been trying to figure out what it’s made of for a looong time. I have tried at least 3 recipes that looked like they were going to be a close replica, all to just be disappointed in the end. Something I do not like is that the other recipes was that they were not moist inside. I would rather use all natural ingredients that do not include a box of a store bought mix, I am able to get past that fact ONLY because this recipe produces an amazing, exact copy of the Starbucks Lemon Cake Loaf!
