Key Lime Cake with NILLA Wafer Pie Crust

I’m learning, being up here in North Carolina, that I will likely never lose my ‘Florida girl’ style, tendencies, and taste. I don’t know if I’ll ever get used to consist 35 degree weather for more than a day or two a year. I also don’t know if I can ever love all the different kinds of BBQ this state has to offer. There’s only one BBQ for me and that’s at First Choice, a restaurant I’ve been going to in the Tampa area for over 11 years! All that is to say that I really love key lime.

I used to live about eight hours to the tip of Key West. Not too bad considering you can hit the beginning of the Keys in a much shorter timeframe than that too. Because of the closeness, it was a fun trip to take with friends; I think I went once a year for a solid stretch of time, maybe even more. Key limes are abundant in Key West – everything from key lime taffy to key lime pie to key lime drinks. There were floats and milkshakes and cookies, all with that distinct flavor I associate with my home state.

The state of naval oranges? Nah, key limes are the things you want.

Key Lime Cake

So my aunt and my mom both wow guests and our entire family with key lime cake. There is plenty of key lime cake in Key West, but this one is the best. We typically make it in a cake pan, but this time around I wanted to try making a pie crust using NILLA Wafers. NILLA Wafers are already sweet and have a hint of vanilla flavoring so I thought they would be an excellent accompaniment to the key lime cake.

Spoiler alert: I was right. It was really simple to make this pie crust and really, the only thing that changed from cake to pie was the cooking time. I had to double the cooking time to cook the cake through, but then it was just as springy and delicious as usual. And surprisingly simple!

With this crust, you can make a cheesecake, pie, cake, or maybe even use the crumbs as a sprinkling on top of a milkshake! Why not.

The NILLA Wafers really came together nicely in the crust and when the cake was done cooking, the NILLA Wafers were still perfect, with a nice deep flavor to them. I really don’t think I’ll make this cake again with anything but this crust!

Of course, green sprinkles are completely necessary! Happy Spring!
