A few weeks ago I needed a last minute desert for a party, so I searched the pantry to see what I could come up with. There are recipes all over Pintrest and the blog world for different ways to make a box cake, so I gave it a try with what was on hand... Chocolate cake mix and blueberry  pie filling.  The results were a very pleasant surprise, perfectly moist cupcakes with just enough fruit taste to set them apart from your usual chocolate. I made them on a Thursday  thinking they would be eaten Friday night, but the get together was delayed until Sunday. I was a little worried they would be dried out after a few days in my cupcake container, but they were just as moist and perfect as the day they were baked (and I know, because I sampled one both days)!
