Someone pour me a martini

I'm supposed to bring dessert to a party this weekend, and randomly decided to make a Harvey Wallbanger cake. My mom used to make these all the time back in the day, so I didn't think anything of it. Then Googling a recipe, everything was like "70s era!" "vintage!" (plus it has booze in it...) - but hey. It seems very Mad Men to me, so what the hell. Bringing it back. (Apparently it was originally a drink - time to bring that one back as well!)
