This creamy, indulgent smoothie tastes like liquid Nutella but is packed with high-quality protein and healthy fats. It's the perfect post-workout recovery drink or a satisfying breakfast that keeps you full for hours.
For a keto-friendly version, replace the banana with 1/4 cup of frozen cauliflower rice and add 2-3 drops of liquid stevia. This smoothie is best enjoyed immediately but can be stored in an airtight thermos for up to 4 hours. If using raw hazelnuts, toast them in a dry pan for 3-5 minutes until aromatic to enhance the nutty flavor profile.
