The glow-in-the-dark doughnut was created by Christopher Thé for his Black Star Pastry bakery in Sydney. Thé says the idea for the radioactive-looking ‘glonuts’ light up vivid came to him when he visited last year’s Vivid festival.

“It was an amazing challenge we just couldn’t resist,” he says, adding it took almost 12 months of development and testing to get the icing to glow.

“The ingredient itself that makes the icing glow is made from vitamin B, which in itself is quite acidic,” explains Thé, who opted for a yuzu glaze to match the tartness of the vitamin B.
