Combine all of the ingredients in a high-powered blender, and blend until smooth and creamy. Add a little more almond milk or water if needed to facilitate blending. (If the shake isn't sweet enough for you, add a tablespoon of maple syrup and blend again.)
Pour into two glasses and serve immediately.
For best results, use a high-speed blender like the Vitamix, which breaks down ice effortlessly. A traditional blender should also work-- though, you may need to add a bit more almond milk to facilitate blending.
