Melt on a low-medium heat until everything is melted and dissolved.
Once melted, turn the heat up slightly to a medium heat and boil the mixture for 7-8 minutes, or until the mixture has started to turn more golden and thickened. Stir it constantly with a spatula so the bottom of the pan is scraped properly.
Pour the Caramel onto the Shortbread and leave it to set in the fridge for an hour or so!
Once set, melt your Vegan Chocolate carefully and pour over! Melt any Vegan White Chocolate if using, and swirl through using a cake skewer or fork!
Leave the bake to set in the fridge until solid, and then cut up and enjoy!
