Simple whole-grain muffins studded with soft, sour pockets of a late-spring treat, rhubarb, some times called "pie plant" because yeah, rhubarb pie. My Rhubarb Muffins are barely sweet and oh-so-tender and definitely – definitely! – not cupcakes. (And oh! That crisp thin layer of cinnamon and sugar on top ... ) For all who prefer a less-sweet, less-rich but ever-so-satisfying morning-bread treat, this is your recipe!
