This is a lemon-lime cake, made with a basic vanilla cake recipe. I turned the layers out onto a cooling rack and poked them carefully with a fork. Then I drizzled them with a simple glaze of confectioner’s sugar mixed with key lime juice and a small amount of hot water to thin.
Once the layers cooled and the glaze dried, I stacked the layers, frosting with a buttercream icing flavored with key lime and lemon juice.
I decorated with a “limon” tree hand-molded and then carved from fondant and painted with Wilton paste food coloring, slightly thinned. The lemons, limes and leaves were made from fondant, colored with gel food coloring. My 11 year old daughter, Erin, made them herself, as she did the letters. The lemon and lime slices are real and were added at the end. It’s a good idea to cut them a bit ahead of time and let them dry out somewhat so the moisture won’t compromise the frosting or the cake.
The “stream” is made with Wilton Gel-Flow, colored blue with gel coloring. The rocks are hand rolled from fondant. The fish in the stream were Erin’s idea and creation. They really added a finished look to the cake.
