Cheesecake Custard Filled Cupcakes

I always swore that I would never use box cake no matter what, but then I got busy... and decided that sometimes it's okay. So, for my dance school's holiday potluck I decided to bring these- mainly because I thought the flowers (sort of?) resembled Hibiscuses and it's a Polynesian dance school so i thought it made sense. A room mate of mine once mentioned that she liked cheesecake custard filling and I had never heard of it. I'm big on Allrecipes.com and I have never seen a recipe for "Cheesecake Custard" anything, so this is what I came up with... simple, but I did get positive feedback

I used a box of chocolate cake mix and a box of yellow cake mix to make two batches of cupcakes. After cooling, I used the cone method to fill them. I doubled the filling and used the standard Wilton Buttercream recipe to ice
them, but any stiff buttercream will do. The flowers were made ahead of time with royal icing.
