Put a pinch of sprinkles into the bottom of each hole, so that it just covers the base.
Melt the chocolate in a bowl using 10 second blasts in the microwave then pour into the heartshaped candy mould, filling each hole just shy of the top.
Use a dough scraper or spatula to scrape away the excess chocolate.
Leave to sit for 10 minutes, then transfer to the fridge to set.
Once fully set, pop out carefully onto a flat surface and you’re done!
