Prepare the Ingredients: Gather the banana, blueberries, almond milk, peanut butter, honey or maple syrup, vanilla extract, Greek yogurt, and ice.
Blend: Add the banana, blueberries, almond milk, honey or maple syrup, peanut butter, Greek yogurt, vanilla extract, and ice to a blender. Blend on high speed until the mixture is smooth and creamy.
Adjust the Consistency: If the smoothie is too thick, add a little more almond milk and blend again. For a thicker texture, add a few extra ice cubes or more frozen blueberries.
Serve: Pour into a glass and serve immediately. For a fun twist, garnish with a few fresh blueberries or a drizzle of peanut butter on top.
