For best results, avoid overmixing the batter so the cupcakes stay tender, and make sure all chilled ingredients are at room temperature to help the batter and frosting emulsify smoothly. If the caramel is too runny, let it cool longer before topping or it will soak into the cupcake; if it gets too thick, rewarm briefly and stir. Add flaky salt sparingly on top—taste as you go, since the pretzels and caramel already contribute saltiness. Store the finished cupcakes in an airtight container at cool room temperature for up to a day, adding extra pretzel pieces just before serving to keep them crisp, and refrigerate briefly on hot days to prevent the frosting from softening too much.
