Add banana, whey, milk, pb powder, vanilla, truvia and ice to the bottom of a high powdered blender. Blitz milkshake together using the damper to get a thick and smooth consistency.: The moment you smell the frozen banana and vanilla together you know you are building depth of flavor; the mixture should look pale and chunky before you start. Start with the liquids lower in the pitcher to help powders hydrate, this prevents dry pockets and reduces the chance of the motor straining. A common issue is overfilling the blender, which can trap air and cause splattering, so respect the max fill line. If your whey protein clumps, pause and scrape down the sides before continuing. Keep a towel handy for any splash, and listen for a steady hum rather than a stressed grind which indicates the blades are handling the load properly.
Divide between two glasses, top with two tablespoons of light cool whip and enjoy!: As the blades engage you will hear the initial crunch of ice soften into a velvety rhythm, and the color will even out to a creamy tan. Aim for a texture that coats the spoon, not overly runny, so you know the balance of frozen and liquid is right. Over blending can warm the shake and thin it, so pulse to reach the desired body, checking the texture between bursts. If you notice bits of unmixed powder on the edges, stop and scrape down, then blend briefly to incorporate. Avoid running the blender excessively long, which may heat the mixture and reduce the refreshing quality.
Divide between two glasses, top with two tablespoons of light cool whip and enjoy: When you pour, listen for the soft, thick pour and watch how it slowly sinks into the glass, a sign of perfect consistency. The addition of light cool whip gives a sweet, airy contrast on top, creating a pleasant mouthfeel difference between spoonfuls and sips. Serve immediately because the whipped topping will begin to melt and the texture will change, which can alter the perceived creaminess. A frequent misstep is leaving the shake too long, producing separation; drink soon for the ideal experience. If you want a fancier presentation, swirl a small spoonful around the rim, but be mindful this adds an extra minute before serving which may start the melting process.
