Place the peanut butter into your blender, then add the ripe banana (frozen or fresh) on top.
Pour in the milk, ensuring all ingredients are covered enough to blend smoothly.
Add the crushed ice and a teaspoon of honey for extra sweetness, if desired.
Pour in the cooled, strong brewed coffee—this adds a bold, adult twist to the smoothie.
Secure the lid and blend on high for about 30-40 seconds, until everything is smooth, creamy, and frosty. You should see a thick, velvety mixture with a warm beige color.
Stop the blender and check the texture—if it's too thick, add a splash more milk and blend briefly to loosen it up. If it’s too runny, add a few more ice cubes and blend again.
Pour the smoothie into a glass, and give it a gentle stir if needed to ensure uniform creaminess.
Enjoy immediately, savoring the rich aroma of peanut butter mingling with the bold coffee notes and the chilly, velvety texture.
