And now the recipe :
Cake Mix one box of Duncan Hines lemon cake mix with 4 eggs, 1 cup of buttermilk, and the amount of oil called for on the box. (This is my go-to recipe for any cake when I don't have time to make it from scratch.)
Icing I started with one jar of Duncan Hines cream cheese icing. I then beat in two pints of blackberries. This seemed a little thin for me, so I added about 1/4 block of cream cheese and some powdered sugar.
Stuffing After the cupcakes had completely cooled, I carefully cut a whole in the center of the cupcakes and spooned in as much icing as would fit.
While these were delicious as-is, like I said, it would have been even better with some real whipped cream on top. This would also hide the mess on top. Enjoy!
