Add the rolled oats to your blender and pulse a few times to break them down slightly.
Place the frozen banana slices, Greek yogurt, almond butter, honey, vanilla extract, and salt into the blender.
Pour in about 3/4 cup of the milk to start.
Blend on high speed until completely smooth and creamy, about 30-45 seconds.
Check the consistency. If it's too thick, add the remaining milk a little at a time until it reaches your preferred thickness.
Taste and adjust sweetness if needed by adding more honey.
Pour into glasses and serve immediately.
