Carrot cake with Lemon Frosting

I used the Betty Croker Carrot cake mix to bake two 8"x2" cakes then I leave them out to cool down for couple hours. Then, I spread the special Lemon Frosting to the cake (both layers), next I colored the frosting to lime green to write "Happy Birthday" - This was my first time to try out the cake deecorating, it was fun and interesting....I know my co-workers can't wait to taste it. Oh, by the way, I made this cake for my co-worker! Happy Baking!
