Coconut Key Lime Panna Cotta - an easy tropical delight with sweet coconut silky smooth custard and a lime mousse.

Last year, I had trouble finding key limes. They were either short in supply or my grocery store just sucked at carrying them so I had to settle for key lime juice. I was eager to get my hands on some fresh key limes this year so I can make everything key lime!! I did not go as crazy as the meyer lemons a few weeks ago but I did get two bags and the first thing I made was this coconut key lime panna cotta. Are you surprised coconut was my first flavor combo? You know me better than that 🙂 But I do have a classic key lime pie on the way for you.

Coconut Key Lime Panna Cotta - an easy tropical delight with sweet coconut silky smooth custard and a lime mousse.

Panna cotta is one of those desserts that I think is very under-appreciated. It is such a delicious concoction that is extremely easy to whip up and should be used as an arsenal in one’s goodie bag. Have guests coming over for dinner? Want to impress the in-laws without a lot of work? Or just have a sweet craving? Panna cotta is the answer!!

I think it was Lindsay who recently called it adult jell-o and I totally agree with her. It’s a silky, smooth, custard with an endless possibilities of flavor combinations. This coconut key lime panna cotta is a tropical delight and just perfect for Spring. A sweet creamy coconut custard is mixed with tart citrus and topped with a key lime mousse that is light in itself to be a stand alone dessert.

So if you are looking for something special, different and just easy to make this Spring, this panna cotta is for you!
