Make a batch of your favorite cupcakes. Let cool.

In a mixing bowl, beat the softened butter until creamy.

Gradually add the confectioners' sugar, mixing well.

Add the heavy cream and vanilla extract, and beat until smooth.

Begin to tightly roll a red sour strap into a rosebud, then loosely twist it while continuing to wrap it around the bud to form the petals.

Tuck the end underneath the rose and secure with one end of a toothpick; stick the other end into the top of the cupcake.
