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.
The glaze is a basic powdered sugar glaze, but dotted with lime zest to give it zing.
Pound Cake Recipes
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.
Key Limes vs Regular Limes
Is there a difference between key limes and regular limes? There sure is!
Key limes are smaller than the usual limes at the store. Their skins are greenish-yellow and they have seeds. They are slightly more tart and have a floral aroma. Both the zest and the juice is more potent than regular limes.
But for the majority of us, we will have trouble getting our hands on true key limes, so feel free to use regular limes if you can’t.
You can also buy key lime juice in a bottle. While I would generally shy away from citrus juice in a bottle (over fresh) this is one scenario where I might go ahead and do it thinking of it more like a flavoring or extract than juice. Just so you get some of the real key lime flavor. Then use zest from regular limes.
The ingredients for lime pound cake are pretty straightforward and simple…
- Unsalted Butter– Salt dries things out and brands can vary on salt content. Always bake with unsalted and then add salt as needed. Also, don’t skimp with cheap butter- it is the base for the is cake. Use a good grade A butter.
- Sugar- This is a rich cake, but not an overwhelming sweet cake. While it seems like a lot of sugar, this is also a LARGE cake and needs to balance out unsweetened cocoa.
- Eggs- Creates structure and stability in the finished product.
- Lime Juice- used instead of vanilla to add the punch you are looking for.
- Flour– Proteins that make up gluten and thus, structure and stability.
- Baking Powder- Leavener to add fluff and neutralize acids.
- Salt– Salt is essential in baking to bring out natural flavors and provide acidity.
- Milk– helps to keep things moist. Try to use a 2% or even full fat milk for the most impact.
- Key Limes– See my whole diatribe above…
This is discussed below, but it is so important that it needs to be discussed twice. USE THE PAN SUGGESTED FOR THE RECIPE.
This recipe calls for 2 standard loaf pans and while the batter will fit into a bundt pan or tube pan, it throws off the baking times.
You can, of course, give it a try, but the baking times will be off and please don’t leave a comment saying it failed miserably. It wasn’t the recipe, it was the pan.
Pound Cake Glaze
The simple cake glaze is just a mixture of 2 cups powdered sugar (confectioners sugar) with a touch of milk and lime zest. You can also add lime juice or vanilla for more flavor, but since key limes are already so flavorful, it wasn’t necessary.
Add milk sparingly. I’m not sure I’ve ever actually made the right amount of glaze. I almost always add too much liquid and then need to add more powdered sugar. Ha!
Mix together right before you are ready to ice, which should be after the cake is fully cooled. Then drizzle on top and allow to set or serve immediately.
I like to do this over a wire rack so the extra glaze drips off instead of pooling around the bottom of the cake. After it sets, transfer it to the serving dish.
