Yesterday was one of my best friends' birthdays, and in honor of it, I made her a cake disguised as a giant margarita. After seeing this cake on Frosted Garden a couple months ago, I knew immediately that I would be making it for Kate's birthday. 
Before adding the final layer of frosting
I had seen these giant margarita glasses before at Michael's (craft store) and picked one up a couple weeks ago to prepare for the cake. I had meant to bring my smallest Pyrex bowl home with me from Hoboken to Toms River, but completely forgot it. Fortunately, after rummaging through my grandmother's cabinets, I found a glass bowl that seemed to be the right size.
After deciding on funfetti cake with vanilla frosting (seemed to be an appropriate "birthday flavor"), I baked the cake for what felt like forever. I'm so used to cupcakes and their short baking time that a deep cake like this tested my patience. Especially since I couldn't wait for this to come out of the oven so I could take a nap.
No Kate, you can't drink that
After the cake baked and cooled, I made some vanilla frosting, tinted it light green, and frosted the bottom and sides of the glass. This part was the trickiest because I had to make sure that you didn't see any spatula lines through the glass. I cut the rounded-bottom cake in half, placed the bottom half in the glass, filled in a layer of frosting on top of it, and then topped it off with the other cake half and another layer of frosting to complete the cake. I added a hot pink straw and a slice of lime to complete the look.
