Featuring a buttery shortbread base studded with semi-sweet chocolate chips, layered with sticky caramel and finished with a swirl of bittersweet chocolate chips, milk chocolate chips and melted white candy, this millionaire bar-inspired recipe is topped with beautiful swirls that look almost too good to eat – but we’ll definitely be eating them anyway!
