Magnolia Bakery's Vanilla Cupcakes with Vanilla Buttercream Frosting

This was my first time to try this recipe. I got Magnolia Bakery's recipe for their famous Vanilla Cupcakes. I didn't have their vanilla buttercream frosting recipe so I got one off of Martha Stewart's website. The cupcakes turned out really yummy! The frosting was a little too runny. I will add more confectioners sugar next time.
