The bulking shake: whole milk, protein powder, peanut butter, banana. Blend it thick, drink it fast, and let the calories do their muscle-building work.
Peel both bananas and break them into chunks for easier blending.
Add whole milk to the blender first to cushion the blades and improve mixing.
Place banana chunks, vanilla protein powder, and peanut butter into the blender, sequencing heavier dry items last.
Add honey for extra sweetness and ice cubes for thickness; pulse briefly to crush ice before blending fully.
Blend on high speed for 40–60 seconds, stopping to scrape down the sides if needed, until the shake is rich, creamy, and smooth.
Pour into large glasses and serve immediately to retain optimal coldness and texture.
