Can you mix pretzels butter and sugar then bake them and leave out of refrigerator all night to make pretzel salad the next day or should it be refrigerated?

Yes, you can mix pretzels, butter, and sugar, then bake them, but it’s best to refrigerate the mixture if you plan to leave it out overnight. The butter and sugar mixture can become sticky and may spoil at room temperature. Refrigerating it will help maintain its texture and prevent any food safety issues.
