I’m not sure how feasible it would be to have a heart sparkler lit on a cupcake tower (the first would probably have gone out by the time you lit the last) but I do think it would be possible to have them inserted into cupcakes and lit just as they are delivered as dessert to your guests. They’re very cute and will certainly add some ‘wow’ to your final course, especially if you’re in an atmospherically lit reception venue. A pack of eight gold sparklers costs £5.99 at Confetti.
