The Barnyard Stack is a triple decker burger, available in stores starting April 2.

It consists of a beef patty, a slice of free-range crumbed chicken, a portion of bacon, and a drizzle of Smokey BBQ Sauce. This protein triple-hit is placed between a milk-bun, alongside lettuce, tomato, pickles, onions, and cheese.

Burger Project is also partnering up with local brewers to take its limited-edition burgers to new level. First up is Young Henry’s classic Pale Ale, the Newtowner. According to a the product release, the Newtowner's fruity yet bitter tang balances the Barnyard Stack’s flavours. Customers can enjoy the limited-edition combo deal, which includes the Barnyard Stack and the Newtowner, for $23.50.

“Our triple storey Barnyard Stack is the burger to beat all burgers, and with the addition of the Newtowner it’s a match made in burger heaven,” said Rockpool Dining Group culinary director Neil Perry. “Who can resist a burger and a beer?”

Limited-edition combo customers will receive an exclusive Burger Project t-shirt, as well as the chance to win a fully catered house party for 10. Winners can choose to host the party in their own home, or at the Young Henry’s Brewery in Newtown, Sydney.
