Time for Key Lime

A few weeks ago The Pioneer Woman tweeted something about Key Lime Cupcakes in Salt Lake City and I thought the idea was brilliant.  The odd thing is that I don’t think I have ever had true key lime pie.  I just really like the idea of it.  Over Christmas I made a quick version key lime pie I found in a magazine, but it was not very good and I decided it was too much of a failure to share.  It did not ruin my desire for key lime and I am glad for that.    
Immediately after reading this tweet, I jumped online and into my 500 Cupcakes cookbook for recipes.  I found many that were like the one I am going to share with you and others had actual key lime cream filling with meringue for frosting.  I thought about combining these recipes to some degree by mixing different cakes with the different frostings, but in the end I decided to stick with the recipe I found on Bon Appetit.  I was feeling lazy and didn’t want to deal with a six step process to make cupcakes.  I will someday, just not now. 

These are delicious and I had enough batter to make 18 cupcakes instead of 12 like the recipe said.  They didn’t rise very much, but maybe they were not suppose to, I’m not sure and I can’t really tell from their picture if theirs did or not. It took me forever to actually bake these because I kept missing one thing or another and I kept missing the fact that the butter and cream cheese need to be at room temperature.  I also added coconut to the tops of half of them.  I think it was a good addition.
