Key Lime Cake

key lime cake

For the few months before the Wedding Cake Buffet I did a lot of experimenting with cake recipes.   Believe me no one around here was complaining.

I put a lot of time and effort into the cake menu and making sure the flavors were balanced and well represented.

I knew that I wanted to have a California Orange Cake, a recipe I shared several years ago.  I think it is my all time favorite cake!!  I also knew I had to have the Best Chocolate Cake  and the bride’s father had requested Red Velvet Cake.  I love citrus flavored cakes so I knew I needed a lemon cake and when I came across the recipe for a Key Lime Cake over at Bakerella I knew it had to be part of the line up too.  How could Bakerella steer me wrong?  She didn’t.  I loved having three citrus flavors represented – lemon, lime and orange.

I loved this cake.  I think I may have eaten more than my share of it.  It is a sweet cake but isn’t that what cake is suppose to be?  Sweet!

The recipe calls for key lime juice.  If you have ever purchased key limes before you know they are small and it would take a lot of limes to get the amount of juice I needed so I just bought the bottled key lime juice – it works great and used the key limes for the photo shoot!

You are going to notice a bit of a difference in the photos in this post.  The first time I made the cake I tinted the frosting with a little green food coloring (see photo above) so some of the photos have green frosting in it but for the actual cake buffet I didn’t want it green so just left it white.    Bakerella’s cake also was beautifully coated in graham cracker crumbs.  I tried that on the first cake and let’s just say my cake didn’t look like her cake and thus you are not seeing photos of it!!  I left the crumbs off for the wedding.

For the wedding I piped the top with whip cream stars and sprinkles.

The cake is made by splitting your two layers of cake into four and layering with frosting.  I love frosting so for me the more frosting the better!

Then you add a layer of the delicious key lime/cream cheese frosting on the top and bottom.  A light, lovely and sweet cake.  Perfect for a wedding cake buffet.

    I’ve actually never made a cake with a whipping cream frosting. How long does this hold up in the refrigerator? Would it freeze well? When you set it out, how long do the decorating dollop thingies hold up?

    • says

      The frosting isn’t actually whipping cream just the piped stars on top and they hold up really well. I refrigerated the leftovers and it held up for several days no problem. Not sure about freezing it though?

    Leigh: Can you tell me what size star tip you used for the piped stars on top of cake? Thanks. Can’t wait to try as I love anything “citrusy”

    Oh my goodness, my dad loves Key Lime so I decided to do this for our Father’s Day party today and made them into cupcakes for easier access for the little ones. These are out of this world phenomenal! Now if only I could be on the beach… :)

    Greetings, I bought some key limes the other day and am ready to bake. I wanted to turn this into a bundt cake. Any changes in the recipe?

  7. Tara says

    I am assuming that the 2 boxes of confectioners sugar ( ingredients)is blended into the cream cheese and butter! It is missing in the directions. Please let me know if this is
    The cake sounds delicious.
