Black Star Pastry’s now-cult strawberry-watermelon cake had humble beginnings. It was initially created for a friend’s wedding, and in 2011, before the cake took off on Instagram, the original bakery in Newtown, New South Wales was selling just 30 portions per day.

Once the internet hordes discovered it there were queues down the street, and now the bakery says it sells one million slices each year.

Given the cake’s origins, it’s appropriate that Black Star’s pop-up in St Kilda has created a heart-shaped version for Valentine’s Day, which you’ll need to order at least three days in advance. You can pick up your order in-store on February 13, 14 or 15. It’ll set you back $36.

The delicate cake, which was created by Black Star founder Christopher Thé, has layers of airy almond dacquoise (meringue), rose-water-scented cream and rose-water-macerated watermelon. It’s prettily topped off with halved strawberries, crimson grapes, Iranian rose petals and slivered pistachios.

While the cake was inspired by love, it’s also generated a lot of love beyond Instagram. Louis Li, the founder of Jackalope hotel on the Mornington Peninsula, loved it so much he bought a majority share in Black Star in 2018.
