That is one of my absolute favorite things to do with food, just throw things together and tinker, but...re-creating is then somewhat tricky.
I am pretty sure I have this one figured out though. No worries.
I brought these in to class so my roommates wouldn't complain about the excessive amount of baked goods in the apartment and, it seemed to go over well. Hopefully you guys can recreate these with similar results.
-1 carton blackberries
-French Vanilla Cupcake Mix
-2 cartons blackberry yogurt
-1/4 cup water, 1/4 cup oil
-Red/Blue food dye to make them REALLY purple and fun :)
Combine cake mix, yogurt, eggs, water, and oil. Mix well. Should be a grey/purple shade. Use dyes to your own liking to make it a more distinct purple in coloring. Grease 2 cupcake pans (24 cup cakes), put 1 blackberry in bottom of each cupcake mold.
The easiest way I have EVER found to pour cupcake batter into the cups without it getting all over me, the pan, and my counters is to pour all the batter into a gallon ziploc and then snip one of the corners with a scissors. You can then squeeze and pour as you would runny icing.
However you choose to do so, pour batter into pans, bake at 350 til golden sides and cooked completely through. Approx 25 min.
