Pepperidge Farm Puff Pastry Oktoberfest Puffzel™ Recipe. Inspired by cheesy stuffed pretzels (and of course, Oktoberfest) these unique Puff Pastry Puffzels make for a perfect fall snack. Simply fill strips of Puff Pastry with cheese and smoked sausage, seal with an egg and mustard wash, twist and bake until golden. We also sprinkled ours with a savory seed mixture before baking. Serve as appetizers while rooting for fall football or enjoy with a cold brew and good friends. Prost!
