Flaxseed Meal (Best Option)
1 tablespoon flaxseed meal + 3 tablespoons water per eggFlaxseed meal mixed with water forms a mucilaginous gel that acts as a binder and moisture retainer, essential for the structure and rise of cinnamon roll dough. The gel helps trap air bubbles during proofing, supporting yeast activity and dough elasticity.
To ensure success, grind whole flaxseeds fresh or use pre-ground flaxseed meal, and allow the mixture to thicken for at least 5 minutes before incorporating. Avoid overhydrating the dough since flax adds moisture.
Compared to eggs, flaxseed meal produces a slightly denser crumb but preserves the chewiness and softness expected in cinnamon rolls, with a mild nutty undertone that complements the spices.
