I used a recipe on the back of a box of flaxseed. It's a basic muffic recipe, except you add flaxseed. I used apples and carrots, shredded, and random ingredients I thought looked interesting (almond extract, lemon juice, nutmeg).
375mL flour (250ml = 1 cup)
125mL oat bran (I substitute rolled oats)
125mL flaxseed
200mL (I think?) brown sugar
250mL apple, shredded (two small apples or one large)
250mL carrot, shredded (almost two)
2 tsp. baking soda (sodium bicarbonate)
1 tsp. baking powder (calcium phosphate, starch)
2 eggs
175mL milk
1 tsp extracts of vanilla
some quantity of almond extracts (I don't know, I sort of spilled it...)
nutmeg
salt
lemon juice (to neutralize the excess baking soda I spilled)
