β Oat Flour (Best Vegan Option)
1 cup oat flour per 1 cup cake flourOat flour is lower in gluten and protein, which reduces binding strength but adds moisture retention and a subtle sweetness. It can help hold the meatloaf together when combined with eggs or other binders.
To ensure success, combine oat flour with an additional binder such as an extra egg or a small amount of ground flaxseed. Avoid overloading the mixture with oat flour to prevent crumbliness.
The meatloaf will be softer and slightly more crumbly than with cake flour, with a unique flavor profile that complements savory dishes.
