If you have ever made the "mock twinkie" filling, make that and add orange extract (and orange food coloring if you want). It's make a fantastic fluffy orange filling. (if you add vanilla as well, it tastes like a creamcicle). I just add the flavorings to taste (which for me, is a lot!). Good luck!
I made an orange-flavored SMBC for my mother's birthday cake. I just made the recipe up as usual and then added a touch of vanilla extract, a touch of orange extract, and the zest from two oranges. (I flavored the whole batch, it took that much but I started with the zest from just one!) It worked beautifully, it came out super-delicious. I had left over, even--until Mom started putting extra on the cake each time she took a slice!
My dad would flip. me, hubby and dad all love Creamsicles 
I love the DREAMSCICLE recipe that was submitted to CC. I have used it as a filling in choc. cups and as part of a trifle. It tasted fantastic!!! If I want to lighten it up a little or stretch it out in a large trifle bowl I will add some extra cool whip to it. I have never brought this recipe anywhere and not come home with an empty container. Fantastic!!! I think it would make an excellent filling for a cake, just be careful you don't eat it all before you finish the cake!!
