Place the peeled bananas into your blender, listening for a gentle thud as they settle. Add the peanut butter on top, aiming for a heaping tablespoon for a rich, nutty flavor.
Pour in the chilled milk, which will help keep your smoothie refreshingly cool and blend into a silky texture. Add a teaspoon of honey if you prefer a touch of extra sweetness.
Toss in the ice cubes, frozen bananas, and optional oats or vanilla extract for added flavor and creaminess. This mixture will turn into a thick, frosty delight as you blend.
Secure the lid on your blender and blend on high for about 30-40 seconds. Listen for the blender’s hum and watch the mixture transform into a smooth, velvety consistency without chunks.
Stop the blender and check the texture—if it’s too thick, add a splash more milk and blend briefly. If it’s too thin, toss in a few more ice cubes or frozen banana chunks and blend again.
Pour the smoothie into glasses, watching as it pours out thick and creamy with a glossy, inviting appearance. Give it a quick taste and adjust sweetness if needed by adding a little more honey and blending for a few seconds.
Serve immediately with a straw or spoon, enjoying the cool, nutty aroma and luscious texture. For extra chill, add a few more ice cubes on top or refrigerate briefly before drinking.
