Yes, just one large egg is needed. I edited the recipe to include it (again). Very glad you liked them. I think orange zest would be a great addition.

(Am hoping you only needed one egg, it’s not in the ingredient list)

Muffin has a real nice texture and is very moist. Tastes great when you get a bite of cranberry (which by the way I’m glad I had a bag in the freezer! My store only had dried cranberries…grrrr).

I think I’ll add some orange zest to the batter next time I make these. That would give the rest of the muffin some flavor.
