Magnolia Bakery is celebrating its 20th birthday in a big way. The New York City institution has released a third variety of its famous banana pudding — and it's one combination we all know and love. Layered with Nabisco Nutter Butter wafers, bananas, and roasted salted peanuts, the limited-edition peanut butter flavor is reminiscent of a classic peanut butter banana sandwich, kind of like the ones my mom used to make (no crust, of course). The dessert joins the Magnolia Bakery family alongside traditional banana pudding and chocolate banana pudding, but the big difference is that its only available through Sunday. Our best advice to you would be to run, not walk, before the batch runs out.
