The quickest route to muffins is a boxed mix, and mixes take a step up with easy added ingredients.
I did a little research after my supervisor, Robin Fornoff, asked about muffin recipes.
I checked a lot of labels to see which mixes had the fewest calories and no trans-fat-carrying hydrogenated ingredients. To save you time, they were Krusteaz fat-free Honey Cornbread and fat-free Cranberry-Orange muffins, Duncan Hines Wild Maine Blueberry muffins with whole grains and Betty Crocker Angel Food Cake.
They all taste nice, and, yes, angel food cake has fewer calories and less hydrogenated junk than most muffin mixes.
For savory muffins, look for less-sweet cornbread mixes.
