Buy a Woopie cake pan or a lady finger pan and you can make your own Susie Q's or Twinkies much fresher and tastier than the ones you buy in the store, just individual wrap, can custom make to taste like orange, coconut, chocolate chips etc, store in fridge to firm up. Add half cup of milk to the cake mix instead of the full amount of water and it is more moist.
My first try, and hubby LOVES them. You have to play with the amount of batter you put in the shallow pan, they make 6 halves at a time. I used cream cheese frosting for the filling. There choices are nearly endless. You need a pipping bag if you do the lady finger pan to fill them...just yellow cake mix, don't forget the milk for added moisture.
