For best flavor, use tart, firm apples (like Granny Smith or Honeycrisp) so they hold their texture in the batter and balance the sweetness of the caramel. Ensure all ingredients for the batter are at room temperature to create a light, even crumb. If your caramel seems too thin, cool it longer; if too thick, gently rewarm with a splash of cream. Avoid overmixing once the flour is added to keep the cupcakes tender, and cool them completely before frosting to prevent the caramel buttercream from melting. These cupcakes are best the day they’re made, but you can store them covered in the refrigerator for up to 3 days and bring them to room temperature before serving so the texture of the cake and frosting is soft and luscious.
