Step 1: Begin by preparing your main ingredients. Peel your ripe banana. Carefully cut the avocado in half lengthwise, remove the pit, and scoop out the creamy green flesh with a spoon.
Step 2: Add all your measured ingredients into your high-speed blender. This includes the banana, avocado, and unsweetened almond milk. If you desire a sweeter smoothie, now is the time to add honey or maple syrup. If you're not using a frozen banana, toss in a few ice cubes for chill.
Step 3: Secure the lid tightly onto your blender. Blend on high speed for approximately 30-60 seconds, or until the mixture achieves a completely smooth and uniform consistency. Ensure there are no visible chunks of avocado.
Step 4: Check the smoothie's texture. If you prefer a thinner consistency, add an additional tablespoon of almond milk at a time, blending briefly after each addition until your desired thickness is reached.
Step 5: Pour your freshly blended smoothie into a glass. For an appealing touch, you can garnish it with a thin slice of banana or a delicate sprinkle of cinnamon. Serve immediately and enjoy the revitalizing flavors!
