These High Protein Peanut Butter Banana Overnight Oats are a nutritious and delicious breakfast option that can be prepared in advance. The oats are soaked overnight in a mixture of milk, Greek yogurt, peanut butter, and mashed bananas, which results in a creamy and flavorful oatmeal. The addition of chia seeds and protein powder boosts the protein content, making it a filling and satisfying meal. In the morning, simply give the oats a stir and top with your favorite toppings, such as sliced bananas, chopped nuts, or a drizzle of honey.
