• Add the dry steel cut oats, flaxmeal, and cinnamon to the boiling water and stir to combine.
• Place lid on top, reduce heat to simmer, and cook for 20 minutes or longer for a softer consistency.
• Pour cooked steel cut oats in a glass container, cover, and place in the fridge overnight to firm up.
