You may have had to cancel travel plans to Florida due to the coronavirus pandemic, but don’t despair: You can bring beachy, island vibes to your home with this yummy Key lime pound cake recipe that will take your tastebuds on a tropical journey.

The recipe comes to us from Barbara Bakes. Barbara says its one of her most popular cake recipes, and once you try it for yourself, you will see why!

The approachable recipe is simple enough for beginner bakers, but special enough to deserve a place on Instagram. Made with fresh lime juice, this pound cake is light, moist and the perfect way to celebrate the return of warm weather and sunshine.

The quick bread is topped with a Key lime glaze, which is super easy to prepare. Simply combine Key lime juice with powdered sugar and vanilla extract, then pour over your cooled pound cake. You can prepare the cake in a tube pan, a loaf pan or a Bundt cake pan. (Epicurious has a handy guide that will explain the rules for substituting baking pans.)

And, if you are unable to find Key limes for this recipe, and can only find traditional limes (also known as Persian limes), no problem. You can still follow the recipe and come up with a delicious result. The difference between Key limes and regular limes is that the former hail from the Florida Keys and are celebrated for their aromatic and lightly tart taste.


According to Cooks Illustrated, Key limes have a higher acidity than Persian limes, which is why they taste less tart. But they are also smaller and contain less juice, so you will need more limes (and more time spent squeezing!) if you’re using Key limes for your recipes.

Not that it needs one, but if you’re looking for a topper for this Key lime pound cake, Walmart’s new margarita-flavored ice cream just might be the perfect match.
