Cut a 2-inch length of fruit-chew candy and set it on a plate. Microwave for 5 seconds. Use a rolling pin to stretch and flatten the candy. Cut a thin strip lengthwise into a banner shape, as shown.
Working with one cupcake at a time, cover it with the pink frosting. Top it with a heart gummy candy. Then bend the ends of the candy banner as shown, and press the banner into place.
Put the chocolate frosting into a zip-top bag and snip off a corner. Pipe the word LOVE onto the banner.
