After reading ALL of the "RAVE REVIEWS" posted about this cake, I had to stop what I was doing and make it!!!! Unfortunately, I didn't have the key limes or the key lime juice, so I used what I had on hand (Real Lime Juice) and had to add a little more than a 1/4 C. to the batter, but it turned out DELISH!!!! While the cake is cooling and still a little hot, I took some (store bought non-alcoholic) Margarita Mix and brushed the outside of the cake with it to create a more moist cake (similar to a simple syrup) so as it sets out in my covered cake pan, it will maintain its moistness. The tartness of the lime juice coupled with the brushing of Margarita Mix was PERFECT and REFRESHING!!!! Everyone in the house LUV's this new cake, and I will be making in now on a regular basis!!!! This was prefect timing for this cake as it is 92 degrees!!!!
