In a blender, combine the frozen blackberries, frozen banana, almond milk (or oat milk), protein powder, and your choice of nut butter (almond or peanut butter). Blend until you achieve a thick and creamy consistency. Adjust the consistency by adding an extra tablespoon or two of almond milk if necessary.

Pour the smoothie into a bowl. This is where you can get creative with your favorite toppings. Sprinkle with granola, fresh blackberries, and any other toppings you like. Some great additions are chia seeds, Greek yogurt, mixed berries, coconut flakes, banana slices, hemp seeds, and flax seeds.

Serve immediately and enjoy this delicious recipe!
