So for last couple of weeks I have wanted to make these cupcakes. I found some cute key limes at the grocery store and had to have them. What do you get when you take a basic Vanilla Cupcake and fill it with Lemon-Lime curd and top it with Sweet lemon-line frosting?? Heaven on earth, tart and sweet and yummy all in one bite! I loved these and so did almost everyone who tried them. In fact my mom wants the lemon-lime curd for her birthday!
