Place the frozen bananas, peanut butter, almond milk, honey, and ice cubes into your high-speed blender.
Secure the lid and blend on high for about 30 seconds, until the mixture is smooth, creamy, and frosty. You should see a rich, velvety texture with no chunks remaining.
Stop the blender and use a spatula to scrape down the sides, ensuring all ingredients are evenly incorporated.
Blend again for another 10 seconds if needed, until the smoothie is thick, glossy, and fully combined.
Pour the smoothie into glasses, observing the creamy, thick consistency and the inviting peanutty aroma.
optionally, garnish with a drizzle of honey or a sprinkle of crushed peanuts, and enjoy immediately for the best texture and flavor.
