Add the oats and water to a small saucepan.
Bring to a boil over medium-high heat.
Reduce heat and cook, stirring occasionally, until the oats reach your preferred consistency.
Keep the oats slightly thinner than desired, as they will thicken after adding the protein powder.
Remove the saucepan from the heat.
Stir in the vanilla vegan protein powder until fully combined.
If the oats become too thick, add a splash of almond milk and stir.
In a small bowl, mix the PB2 powder with a little water until it reaches a peanut butter-like consistency.
Transfer the oats to a serving bowl.
Top the Peanut Butter Banana Protein Oats Recipe with sliced banana and prepared PB2 mixture.
Serve immediately and enjoy.
