I just made these and used a SAD recipe but modified it to be legal. I just ate one and it was quite good. Broke my new 100% compliance rule because of the walnuts and sugar! But I had to test them..... they are for Mr. Doodlepunk to take to work and I need to make sure they were OK.

This is the very first time I've made muffins and they were as good as some SAD muffins I've had.
2 eggs' worth of Ener-G Egg Replacer, mixed with water as directed
1/2 of one banana, mashed
1 cup milk sub (I used almond milk) with one tablespoon vinegar
3 teaspoons vanilla extract
1 1/4 cups brown sugar
Mix all above and set aside.
2 1/2 cups whole wheat flour (I used home ground soft wheat, spelt would be good or King Arthur White Whole Wheat, or just regular whole wheat flour)
2 teaspoons baking powder
2 teaspoons baking soda
1/2 teaspoon salt
Mix the dry ingredients, combine with about 2 stirs with wet ingredients, then add:
3 cups finely sliced rhubarb
1 cup chopped walnuts
Stir briefly just until combined. Fill 18 muffin tins, sprinkle tops with a little cinnamon sugar.
Bake 350 for 40 minutes.
