For best results, ensure the flour for the cookie dough is fully heat-treated and completely cooled to keep the filling safe and not gummy, and let the cupcakes cool fully before filling or frosting so the cookie dough centers and buttercream do not melt. If the frosting feels too soft, chill it for 10 to 15 minutes before piping, and if it feels too stiff, add milk or cream a teaspoon at a time; these cupcakes keep well covered in the refrigerator for up to 3 days, but let them sit at room temperature for 15 to 20 minutes before serving for the best texture and flavor.
