Hello Kitty Cake for the second time

When I made the Hello Kitty cake and cupcakes for my friend (see here), my daughter, seeing the first creation, love it so much that she wants to have one for her birthday. 

And so I tried the second time using the chocolate cake recipe from my friend Jimmy and still get frosting inspiration from Michelle of i-heart-baking.

My chocolate cake was nicely done :) and yep I have to deal again with the cream cheese frosting. Googled for recipe, looking for something like maybe a pipeable one yet they all says the same -- like a cream cheese, a butter, a vanilla and a confectioner sugar makes up a good cream cheese frosting. 

But doing it still gives me the same output -- a runny frosting!

- must be the mixer huh? 

- or the weather? 

- or for reasons I still don't know :( 

I need to put them back in the fridge for sometime so I could pipe the the face using the star tip. But when the frosting didn't held up in the sides, I used stick wafers instead. 

Found out that the combination doesn't look bad :) and the birthday girl likes it much :)
