Pulse blender until all ingredients are equally incorporated and mixed.

Notes
Add the peanut butter in closest to the blade of the blender. So for larger blenders, add the peanut butter first, and for one-serving blenders, add it last. This prevents the peanut butter from sticking to the sides and helps it mix into the smoothie easily.
Not Vegan? Use cow's milk or add whey-based protein powder.
Want more protein? Add hemp seeds, chia seeds, or a vegan protein powder.
Gluten-free? Just make sure to select a certified gluten-free brand of oats.
