These muffins will keep in the fridge for up to 6 weeks. Just scoop out what is needed each day and refrigerate the rest. You will need a large container that holds 2+ quarts of batter with a lid. I use my dough rising bowl and lid that I got from King Arthur, but in the past I used a half gallon pitcher with a lid.
