The most important part of these cupcakes is the buttercream frosting. The cupcakes are made of a basic vanilla batter, consisting of milk, vanilla extract, salt, eggs, sugar, butter, flour and baking powder. After they have baked and cooled, the fun begins — piping on the buttercream frosting so that it resembles flower petals. Put a chocolate candy in the center of each and voila! You have a pretty springtime treat to serve to your guests.
