For best flavor, use fresh, soft brown sugar so it creams easily and gives the cupcakes a deeper caramel note; make sure all refrigerated ingredients are at room temperature to help the batter emulsify and rise evenly, avoid overmixing once the flour is added to keep the crumb tender, and if you bake in a dark metal pan check for doneness a couple of minutes early to prevent overbrowning—cupcakes are done when the tops spring back lightly to the touch and the edges just start to pull away from the liners.
