I need some help naming this recipe! Does anyone remember these Bran Muffins?

They were popular in the 70's and 80's, made with All-Bran and buttermilk, and the recipe makes a LOT—you can keep the batter in your refrigerator for up to six weeks.

I'm having trouble naming them so people can find them! Hoping you all could help. Could you let me know what you might call these muffins?

Here are some ideas:
Buttermilk Bran Muffins
Refrigerator Bran Muffins
6-Week Bran Muffins
All-Bran Muffins
Any other ideas? Think of what you might put into a search engine if you're looking for this recipe.

Thank you in advance!!
