Some things just cannot be "diet"

This is why, maybe, diets don't works so well for me.  I have a hard time modifying certain foods to make them "diet".  I would rather not eat the food at all, then eat a inferior version of it.  Yesterday was my birthday and the hubby made me (and a group of friends) dinner and a cake. I requested pineapple upside down cake.

 
You can't make this without butter.  I am sorry.
