Keylime Cake

I had the most FABULOUS cake last Saturday. Harrison's band hosted a marching band competition. I was part of the hospitality group. We fed all the volunteers; and then, we also had a special dinner for the judges complete with dessert. The head of the hospitality committee made key lime cake for dessert. The judges left a few pieces and I got a taste. OH MY!!! It is so refreshing and rich. It has a really fun green color, too. Now, I have some cake to go with my Key Lime Pie Ice Cream I make :c).
I just got the recipe for the cake. It's from allrecipes.com.
Here it is:
