Created by the Woolworths Bakery team, the Pumpkin Spice Mud Cake is adorned with a pumpkin spice ganache, drizzled with white chocolate and topped with pecan cookie crumb.

"Our latest Mud Cake innovation, the Pumpkin Spice Mud cake, is inspired by the growing global love for pumpkin spice flavours, especially around Halloween," Woolworths Chief Cake Maker Laura Mcleod said.

"We've seen this trend resonate strongly with Australians year after year, which is why we know this delicious new flavour will be a Halloween hit," she continued.

The limited-edition Pumpkin Spice Mud Cake is available in stores and online for $7 from Wednesday, October 16.
