Lower the oven temperature to 350F and bake for another 15 to 17 minutes, or until muffins are done. Muffins are done when a toothpick inserted in the center should come out clean, or with a few moist crumbs, but no batter.
Allow muffins to cool in pan for about 10 minutes before removing.
Nectarines are in-season right now. During the height of the season, nectarines are plentiful and cheap. Here’s a twist on the classic blueberry muffin. Just substitute the blueberries for nectarines. I also used avocado to lighten up the recipe. Healthy and good!
