To a high powered blender add: old fashioned oats, banana, almond milk, almond butter, brewers yeast, honey, ground flaxseed, cinnamon, and ice cubes.
Blend until smooth.
Serve immediately. Enjoy!
Notes
Honey: You can add just 1 tablespoon of honey but the smoothie isn't as sweet and you'll be able to taste a more pronounced "brewers yeast flavor." Banana: If the banana is smaller, add 1.5-2 bananas to your blender. Also using a very ripe banana will help give it a great banana flavor to your smoothie. Brewer's yeast is thought to increase breast milk supply, however, there don't seem to be any clinical studies on it to scientifically prove it. Talk to your doctor before adding Brewer's yeast to your diet since some medications you may be on don't interact well with it.Don't have Brewer's yeast? That's OK. Just omit it.Milk: You can use other forms of milk instead of almond milk. I like using almond milk because it has fewer calories and pairs well with the almond butter. But you can use regular cow's milk, oat milk, soy milk, etc.
