Key Lime Pound Cake is a riff on my favorite (and award winning) Vanilla Pound Cake. The cake itself is a little lighter than most pound cakes, but with buttery flavor and in this case, a gentle lime flavor. Think key lime pie in cake form.
What is Pound Cake?
Pound cakes, as a rule, are a little heavy. If you want a light, moist crumb, this isn’t your go-to cake. But when you need a comforting buttery dessert, they hit the spot.
They got their name because the original ingredient list was simple. One pound of butter, one pound of sugar and one pound of flour with a few eggs. Hence, pound cake.
But with no leaveners or other flavors, this also meant they were heavy and needed to be accompanied by sauce or fresh fruit. Since, many variations of pound cake have emerged. My key lime cake being one of them.
