When you use the aluminum foil baking cups, like from Reynolds, they come with paper liners in between themDo you put the batter in the aluminum cup directly and discard the paper liner, or do you put the batter in the paper cup inside the foil cup?
You can use them both, but I ditch the paper - your cupcakes will stick much less to the metallic linersJust be careful, they cook a little faster in the metal ones than the paper.
potatoes take longer to cook than carrots this might be the reason they burned.
