I had left over pumpkin pie filling after making my Thanksgiving pies; I think my pie shells were smaller than the package advertised! I really dislike throwing unused food away & wanted to try & find a use for it. So I made up this recipe. It is a very tender cake; with a hint of pumpkin & very reminiscent of carrot cake. It ended up that I did not have standard size cupcake liners so I had to make jumbo cupcakes. I got 9 jumbo cupcakes so I am guessing the recipe would make about 18 cupcakes in all. I do not think this batter would hold up well in a standard cake pan, to crumbly & tender. But if you try it & it works please let me know.
