This creamy, nutrient-dense smoothie is packed with Omega-3 fatty acids from walnuts and potassium from bananas to boost cognitive function and sustained energy levels. Perfectly balanced with Greek yogurt, it provides a brain-fueling breakfast or afternoon pick-me-up.
For the best texture, use bananas that have brown spots on the peel before freezing. To make ahead, portion the dry ingredients and bananas into freezer bags; just add milk and yogurt when ready to blend. Leftovers can be stored in an airtight jar in the fridge for up to 24 hours, though some separation is natural—just shake before drinking.
