Chicago-based donut shop Stan’s Donuts is teaming up with another big baking name in the Windy City, Magnolia Bakery, on a limited-time offer combining their signature products.

Using Magnolia Bakery’s famous banana pudding as inspiration, Stan’s has created a Banana Pudding Bismark, available beginning June 29 through July 12 at all Stan’s locations. Made with Stan’s classic bismark donut, the Banana Pudding Bismark is cut in half and filled with a combination of pastry cream, mashed bananas and crushed vanilla wafers. The bismark is then topped with a brûlée sugar coating.

The partnership came to fruition when Stan’s founder, Rich Labriola, was given the famous Magnolia Bakery banana pudding for his birthday and immediately got the inspiration for a collaboration.

“The collaboration of two great brands showcasing Magnolia Bakery’s signature banana pudding felt like a perfect match,” says Labriola. “Since partnering with Magnolia Bakery, we were able to collaborate seamlessly in order to create a great donut featuring our signature bismark and their signature pudding for all of Chicago to enjoy.”

“We’re so excited to bring an all-new variation of our banana pudding to Chicagoans this summer,” says Sara Gramling, vice president, public relations at Magnolia Bakery. “When we first opened our Chicago store in 2011, we were thrilled at the excitement that customers showed when first tasting our banana pudding. That’s why, when the incredible Stan’s reached out about a partnership, we knew it was a perfect fit. It’s an honor to partner with such a legendary Chicago company to bring the Banana Pudding Bismark to life. We hope fans enjoy our first-ever donut as much as we do!”

Stan’s Banana Pudding Bismark donut will be available at all 16 Chicagoland locations at a special price of $4.25 per donut. Everyone who orders the Banana Pudding Bismark at Stan’s will also be treated to 10 percent off in the Chicago location of Magnolia Bakery from June 29 through July 19. Customers will need to show their Stan’s receipt to get the discount (in-store only).
