In a high-speed blender, combine the yogurt, strawberries, banana, ground flax seeds, and milk. Secure the lid and blend until smooth.
Stop and scrape down the sides of the blender, if needed. Once the smoothie has no visible chunks, give it a taste and make any adjustments, as needed. You can add a drizzle of honey or maple syrup, for sweetness, or add a handful of ice for a slushy texture.
Serve the smoothie immediately for the best flavor and texture. If you have any leftovers, pour them into a popsicle mold and freeze them for a frozen treat in the future.
Notes
Nutrition information is for the whole batch. This information is automatically calculated using generic ingredients, so it's just an estimate, not a guarantee.Yogurt Note: This recipe was tested with vanilla goat's milk yogurt by Redwood Hill Farm. If you use plain Greek yogurt, it will have a more tangy, sour flavor, so you might want to add extra sweetener in that case.Customize It: Feel free to add any other extras you love, like a scoop of protein powder, or a few tablespoons of rolled oats. Leave out the ground flaxseeds if you don't keep them on hand. This smoothie is easy to change based on what you have on hand.
