You will need to watch the first batch as all ovens bake differently. I always use a toothpick to check to see if the center is done.
Regular size muffin tin bake for 13-15 minutes or until golden.
Large muffin tin bake for 16-19 minutes until golden.
Remove from pan and allow to cool for 10-15 minutes. These muffins freeze really well, I have kept them in the freezer up to a month. I will just pull one out each morning and allow it to defrost for 30 minutes or so. Enjoy!
