A gluten-free muffin using Bob's Red Mill "Mighty Tasty Hot Cereal" I omitted the cranberries and walnuts to see what the flavour would be like AND I only used 1/4 cup of sugar and it was plenty sweet for me. Maybe you need the extra sugar if you use the cranberries. You could add lemon rind, blueberries, cinnamon....whatever to switch things up.
