Almond Meal/Flour - Bob's Red Mill. If you can find almonds on sale for $5/pound and make your own flour, you save money, but not time. And, caution, sometimes almonds will turn to almond butter, not flour. See recipes about making almonds into flour.
Bob's Red Mill Flaxseed Muffins. Recipe is also on the back of the bag of Bob's Red Mill Ground Flaxseed Meal. Recipe on the bag calls for brown sugar. Attached recipe uses maple syrup. Either would work. I also didn't use aluminum free baking soda. Just what I had on hand.
