Remember those Key Lime Cupcakes I made a few weeks back? Well - I made them into a cake! If you wanted to make the cake, use the first key lime cupcake recipe , but double the recipe. I also used the same frosting recipe, but I used a little more powdered sugar so the frosting would be stiffer. The cake I made was 4 layers (it could/should have been five layers, but I didn't want to stay up any later baking), so I made a batch of "mini-muffin" cupcakes. Here are the pictures of the cake and the reaction from the birthday girl, my grandma! HAPPY BIRTHDAY GRANDMA!
