15 Key Lime Cake Recipes

Key Lime Sponge Cake

We are kicking off the list with a simple yet sweet key lime recipe: a delicious sponge cake with a citrusy twist. 

This is an easy one! All you need to recreate this Key Lime Sponge Cake is the usual ingredients needed for a sponge cake – flour, butter, eggs, sugar and vanilla extract – along with some lime juice and milk. The finished product is drizzled with a tangy glaze, made from icing sugar, lime juice, and lime zest. This is a recipe you should definitely give a go!

Key Lime Pound Cake

Next up, we have another traditional recipe combined with delicious key lime flavors. This pound cake not only tastes great, but looks awesome.

The reason a pound cake was given its name is due to the fact that, usually, a pound of each ingredient is used to create the dessert (e.g. one pound of flour, one pound of sugar, […]). This recipe is pretty much the same as your usual pound cake, with some differences made to make it a key lime variant.

Key lime juice is required for the cake batter and the icing glaze, plus it is optional to add green food coloring to the batter, making the cake a lovely pale green color. 

Easy Key Lime Coconut Cake

Key lime and coconut: truly a match made in heaven. If you have never tried this combination before, you will need to give this recipe a try.

The spongy dessert itself is fantastic straight out of the oven, but the rich, zesty lime topping elevates it to new heights. The two-ingredient key lime icing is drizzled over the top while it is still warm, soaking directly into the moist cake, while the remainder produces a delicate, crunchy, sweet coating on the outside.

Key Lime Ice Cream Loaf

Is there anything better than a cold, crisp slice of ice cream cake on a hot day? 

Well, yes, there is: a cold, crisp slice of key lime flavored ice cream cake.

This Key Lime Ice Cream Loaf is refreshing and light, perfect for those summer days spent outside. The combination of creamy, tangy key lime ice cream and crumbled layers of cookies is just exquisite, both in taste and appearance.

On a hot day, this key lime flavoured ice cream cake is the ultimate dessert to share with friends.

Key Lime Strawberry Coconut Ice Cream Cake

Remember how we said that coconut and key limes are a match made in heaven? Well, add some fresh strawberries, and you triple the tastiness.

This Key Lime Strawberry Coconut Ice Cream Cake mixes three great flavours into one vibrant ice cream cake that requires no baking, no churning, and is packed with delicious fresh fruit. The cake’s rich, creamy layers of green, white, and pink are visually gorgeous, making it almost too good to eat.

Key Lime Pineapple Upside Down Cake

If you love key lime pies and pineapple upside down cakes, you will adore this delicacy, which combines the two classic desserts.

The subtle dose of key lime juice and zest, along with the sweet, juicy pineapple, creates a burst of wonderful fruity flavors. While this may appear to be an unusual combination at first, trust us when we guarantee that you will not be disappointed if you try this recipe. 

15 Minute Key Lime Trifle

The only thing better than a delicious, visually stunning dessert is one that takes such little time to create. Less time cooking, more time eating!

This dessert is mainly made from ready made ingredients, designed to provide you with a gorgeous and delicious dessert in a pinch of time.

However, you could always switch up the recipe so that you are making it completely homemade if so desired. This trifle looks so good, due to its pale green tint, that you won’t want to eat it!

Key Lime Creme Poke Cake

This Key Lime Creme Poke Cake is a delicious treat to share with your friends and family… although, you may not want to share.

This tasty dessert is so quick and easy to create, filled with delicious zesty, lime flavoring. The moist sponge tastes great enough on its own, but combined with its deep-dug holes filled with citrusy gelatin and creamy Cool Whip, you are surely onto a winner. 

Dig in!

Key Lime Icebox Cake

Look no further than this incredible Key Lime Icebox Cake for the ultimate summery treat to savor by the seaside.

The only drawback to this dish is that it can take up to eight hours to make due to the requirement to completely freeze it before eating. However, the wait is well worth it, and you will be even more grateful when you eventually get to taste this scrumptious treat.

While this combo of flavors may seem strange at first, it makes sense when you consider that this cake is, essentially, the non-alcoholic dessert form of a Mojito. If you wanted to go all the way, and you are feeling a little adventurous you could even add some white rum to the recipe!
