Super Sour Cake
I have made this as cupcakes a couple of different times and varied the recipe a little each time. I didn't pay enough attention the first time I did it and I put the concentrate in the batter before it was baked, and I have to say, that was the best batch! Got the most compliments on it. I also use a whipped buttercream frosting to off set the tart, they are winners for adults even moreso than kids!
