Scoop KitchenChalky or floury
Chalkiness is a dry, dusty finish from protein powder, cocoa, pudding mix or starch that never fully hydrated, or simply from too much of it.

Answer what you know. The most likely cause moves to the top.
3 possible causes
Protein powder, plant protein most of all
Most likelyHow to tell: It tastes like the shake, with a dusty finish. Pea or rice protein, or more than one scoop.
Why: Plant proteins and some whey powders do not fully dissolve. The tiny particles feel dusty on your tongue.
Fix this tubpint
- Re-spin with 1 to 2 tbsp of milk. It helps a little.
Next time
- Blend the base and let it rest for 10 minutes, or overnight in the fridge, before freezing so the powder can soak up the liquid.
- Use one scoop per 473 ml16 oz tubpint and swap some of it for Greek yogurt.
- For vegan tubspints, soy protein is usually smoother than pea.
Raw cocoa powder
Most likelyHow to tell: A chocolate tubpint with a dusty, slightly bitter finish.
Why: Cocoa powder needs heat or fat to hydrate. Stirred into cold milk, it stays dusty.
Fix this tubpint
- Nothing to do for this tubpint. A drizzle of sauce on top helps.
Next time
- Whisk the cocoa with the sugar and a splash of hot milk to a smooth paste before adding the rest.
- Replace part of the cocoa with melted dark chocolate.
Pudding mix or starch that did not hydrate
Most likelyHow to tell: A floury, starchy taste.
Why: Instant pudding mix needs a few minutes in cold milk to thicken. Cornstarch needs cooking.
Fix this tubpint
- Re-spin with 1 tbsp of milk.
Next time
- Whisk the pudding mix in and let the base stand 5 minutes before freezing.
- Cook cornstarch bases until they thicken, like our gelato recipes do.

How do I make protein ice cream less chalky?
Blend the base and let it rest before freezing, use one scoop of a good whey or whey/casein powder per tubpint, and swap some powder for Greek yogurt.
Why does my chocolate ice cream taste dusty?
The cocoa did not hydrate. Whisk it with sugar and a little hot milk into a paste first, or use some melted chocolate.
