"This is another Paula Deen magazine recipe that we loved. I always have Key lime juice on hand, so when I saw the recipe I had to try it. The cake is light with a yummy white chocolate frosting."

    How would I adjust baking this recipe as Cupcakes, instead of as 3 round layers? Baking later today for an office function tomorrow. Many Thanks!

    Once you bake the cake can it be stored at room temperature or does it have to be put in refrigeration refrigerator then Frost afterwards

    I made cup cakes out of this recipe and they are delicious. I baked them at 350 deg. for 16 min. I got 36 cup cakes and sprayed the foiled cup cake tins with Pam cooking oil. Flavor is wonderful... will be making these again. Thanks Paula!!

    This came out fabulous. I made it exactly as recipe stated. I will be saving this recipe for sure. The white chocolate buttercream paired so well with the lime. I think it would go well with many other flavors too.

    Lovely cake! I made double the frosting to be able to really decorate it. The lime flavor was VERY subtle so next time I will include lime zest in the cake and lime juice in the frosting.
