I know you want vanilla, but I did find a Godiva Chocolate Buttercream for later use, perhaps.
1 cup (2 sticks) butter, softened
2 cups sifted confectioners' sugar
1 cup sifted unsweetened cocoa powder
1/3 cup Godiva Liqueur
Beat butter in bowl until smooth, using electric mixer at medium speed. Sift sugar and cocoa over butter and add Godiva Liqueur, beating until smooth, using low speed.
