Key Lime Coconut Cake

Icing the Key Lime Coconut Cake
Key Lime Coconut Cake

Can a cake be both decadent and refreshing? It sure can! Coconut Cake with a hint of key lime will make you feel like you are on a tropical vacation.

I absolutely love anything coconut. After craving coconut cake for days on end (no I'm not pregnant LOL), I decided to make one. Before I got started though, I asked myself "How can I turn this up a notch?" That's when I decided a hint of lime was exactly what it needed.

Husband and son approved, I bring you Key Lime Coconut Cake!

A few notes about this recipe: This recipe makes either 24 cupcakes or a 3 layer cake (using 9 inch pans). I recommend using parchment paper liners for both. If you choose to make the cupcakes, use a large amount of icing on each one or you will have leftover icing which works great on sugar cookies. Be sure the ingredients noted at room temperature are at room temperature. And if you can't find coconut flakes, you can put coconut shreds in the food processor to get them more fine. Oh, and definitely use fresh lime juice, not jarred. A few drops of food coloring in the icing will give the perfect pale green color!
