Funfetti Cookie Cake

I made this cake to celebrate my own birthday the night before. I spent my actual birthday giving my 251 research talk in front of my area's department, which is sort of like our version of a master's thesis defense. And it was the last day of the quarter for the year. Needless to say I was a little preoccupied and wanted an easy, homemade dessert as a treat for afterwards.


I've always heard butter extract is the key to "cake batter" flavor without using cake mix, so I when I saw a bottle at Ralph's, I snapped it up for this purpose. You could totally decorate it with frosting, but like I said I was busy. Even without any frosting, it was super delicious and the perfect way to end my birthday (and a long quarter)!
