From Joy of Vegan Baking. These are AMAZING!! In this recipe, the eggs are replaced with ground flax seeds. When using ground flax seed to replace eggs in a baking recipe, the ratio is always 1 TBSP flax seed to 3 TBSP water. Ground flax seed has a bit of a nutty flavor and it is best used in recipes like pancakes, waffles, muffins, breads and oatmeal cookies, and as an added bonus, flax seeds are the most concentrated source of omega-3 fatty acids.
