Add liquids first. Pour milk into the blender to help everything blend smoothly from the start.
Layer the rest. Add Greek yogurt, frozen banana, protein powder, nut butter, vanilla extract, and any optional sweetener or spices.
Top with ice. The ice helps create a thick, frosty texture. Start with a few cubes and add more if needed.
Blend until silky. Blend on high for 30–45 seconds, stopping to scrape down the sides if needed. You’re aiming for a creamy, shake-like texture.
Taste and adjust. If it’s too thick, add a splash more milk.
If you want it sweeter, add a touch more honey or a couple of dates. Blend again briefly.
Serve and sip. Pour into a large glass or an insulated to-go cup. Drink right away for the best texture.
