For best texture, avoid overmixing the batter so the cupcakes stay tender, and be sure they are completely cool before filling and frosting to prevent the filling from melting and the frosting from sliding off. If the peanut butter–caramel filling seems too thick, loosen it with a teaspoon of cream at a time, and if the frosting is too soft to hold its shape, chill it for 10–15 minutes and re-whip briefly. You can freeze unfrosted cupcakes for up to a month, then thaw and decorate as needed, and feel free to adjust sweetness by using lightly salted peanut butter or adding a pinch of salt to the caramel drizzle.
