Add the milk and cream cheese to your blender first. This helps the cream cheese blend smoothly without sticking to the sides.
Pro tip: using softened cream cheese prevents lumpy disasters.
Drop in the Greek yogurt, protein powder, frozen strawberries, and vanilla extract. The frozen fruit is your built-in ice maker, so you don't need to add any extra.
Secure the lid tightly. IMO, there's nothing worse than a kitchen ceiling decorated with pink splatter.
Blend on high for 45-60 seconds until the mixture is completely smooth and has a thick, milkshake-like consistency.
Give it a quick taste test. Adjust sweetness if needed with your chosen sweetener and blend for another 10 seconds to combine.
Pour into a glass, sprinkle with graham cracker crumbs if you're feeling extra, and consume immediately for the best texture and flavor.
