For an extra burst of lemon flavor, brush the cooled cupcakes with a simple syrup made from equal parts lemon juice and sugar, heated until the sugar is dissolved. Ensure that the butter is properly softened for both the cupcakes and the frosting to achieve the best texture. Sifting the confectioners' sugar will result in a smoother, less grainy buttercream. For a more intense blackberry flavor, consider using blackberry puree instead of jam. Strain the puree to remove any seeds.
