Key Lime Pie (without the pie)

I've been wanting to try a key lime pie cupcake recipe that I saw on another blog and this weekend was the perfect chance! I followed her recipe exactly being the first time around and they turned out good. Not great, but good. The icing and cupcake part turned out good, but they should have had a key lime pie center. The recipe said to let the center set up for 2 hours before filling the cupcakes with it. I did that but mine was still too runny. It wouldn't pipe well into the cupcakes and ended up making a big mess! I don't think very much of it actually made it into the cupcakes! Oh well, the overall turnout wasn't all that bad. The icing was a lime flavored cream cheese icing with graham cracker crumbles on top, yumm! Again, I'd have to say the icing was the best part. Or maybe I think that everytime :)
