Key Lime Cake with Cream Cheese Lime Icing

Talk about a cake with some zing! This Key Lime Cake has all kinds of fresh tangy flavors—it feels like a party in your mouth! Use fresh key limes to make the cake, and spread some of this zesty Cream Cheese Lime Icing between the layers and on the outside to send it over the top! It’s perfect for birthdays and all kinds of other celebrations. The fresh fruity flavors make it perfect for serving outdoors.
Birthdays are always a really big deal in our home. We enjoy a week of fun with the birthday girl or boy picking out all the meals. Though we do have two kids with the same birthday (they love it, by the way), a birthday gives us an opportunity to throw a special celebration for one child.
From the time they could talk, the kids were in charge of how we spent their birthday (within reason). That’s everything from the venue to what we ate, including the cake or dessert. Interestingly enough, the kids have rarely elected to have a huge birthday party. They usually settle for long hikes on our land with family and a nice birthday meal we can all enjoy together. I’ve been very thankful for that. I like to enjoy their special day as much as they do, so it gives me a chance truly cherish the moment with my birthday child without having to be “in charge” of a production. Of course, we will do the “big” birthday thing every once in a while, but for the most part, we just enjoy each other and great food.

This year, Emelia, my youngest, chose to go out on our land and ride 4-wheelers after a great meal of homemade hamburgers and twice fried fries! If you’re following my Facebook live broadcasts each Sunday, you know we don’t have water at our new property yet, so it was little more difficult, but it actually turned out quite nicely. We ate in the barn on picnic tables and enjoyed each having each other around! After that, we rode the ATVs and ate cake under the Hackberry trees behind the little cabin on the property.

I had never had a Lime Cake until my mother-in-law brought one over. Wow, was it fabulous! Using a lime jello packet gives this cake its zing, along with the fresh limes of course. It’s a relatively easy cake, and you won’t have leftovers! My mom doesn’t like cake, but she definitely loved this one. It’s tart with just enough sweetness to make this the perfect cake for just about any occasion.
Come to think of it, I think I’ll make it for St. Patrick’s Day next year.
Well, now I’m starting to realize that my kids are growing up way too fast! I’m trying to soak it all in.

For the Key Lime Cake
