This is a revision of previous recipes I've posted and I think this recipe's the best, so far. These are moist, healthy, substantial and they're 'total money' with cream cheese or nut butter for a fast breakfast. Note: I use almond milk in these to cut the carb count - the recipe works with any milk or, if you don't need to boost the protein, use water in place of milk.
You may also vary the grains/bran/flours to suit your needs, preference, and what you have in your cupboard. If you need to stretch the recipe, you can add more liquid and more bran/grains/flour. This is a very forgiving recipe. For instance: substitute garbanzo flour for the soy flour, oat bran for the wheat bran, whey powder for the flour.
Also, the lemon juice/soda helps these fiber-rich muffins rise.
Bonus: it takes less time to prepare the batter than it takes for the oven to preheat.
