Why you’ll love this sludge trio
- 28g protein per shake for just 270 calories
- Low carb and sugar-free — exactly as promised on the cover
- In the glass in a genuine 5 minutes
- Three flavours from one simple base
- Thick enough to eat with a spoon — real sludge, not a smoothie
- Dessert-shop looks, meal-prep macros
Health notes
- Greek yogurt and protein powder: The double-protein base that makes every flavour work.
- A pinch of xanthan gum: The thickener that turns a shake into sludge — a little goes a very long way.
- Sugar-free everything: Cookies, syrup and cheesecake crumb all have sugar-free versions — the regular ones break the claim.
- Real strawberries: A small handful gives the cheesecake shake its colour and flavour.
- Locked from the cover: The photo supplied the title, flavours, claims, time and macros, so they are kept consistent throughout the block.
Key element — less liquid, more ice, short bursts
Sludge is a battle against liquid. Start with HALF the milk you think you need, a full tray of ice and a pinch of xanthan, then blend in short bursts, tamping down between each one. Add milk a tablespoon at a time only if the blender stalls. Blend it like a smoothie — long and liquid — and you get a drink; blend it thick and reluctant and you get the spoon-standing sludge in the photo. Serve immediately: it loosens as it sits.
Ingredients
Base (per shake)
- ¾ cup plain Greek yogurt (0% or 2%)
- 1 scoop (30g) protein powder — flavour matched below
- ¼ cup milk or unsweetened almond milk, plus more only if needed
- 1½ cups ice cubes
- ¼ tsp xanthan gum
- 1–2 Tbsp erythritol or monk fruit sweetener, to taste
- ½ tsp vanilla extract
- Pinch of salt
Cookies & Cream Protein Blizzard
- Vanilla or cookies-and-cream protein powder in the base
- 2 sugar-free chocolate sandwich cookies, crushed — half folded in, half on top
- Sugar-free whipped cream, to top (optional)
Peanut Butter Fudge Protein Sludge
- Chocolate protein powder in the base
- 1 Tbsp peanut butter powder (or 1 Tbsp peanut butter)
- 1 Tbsp cocoa powder
- Sugar-free chocolate syrup, to swirl the cup and drizzle the top
- 1 tsp almond-flour crumb or crushed sugar-free cookie, to finish
Strawberries & Cream Cheesecake
- Vanilla protein powder in the base
- ½ cup strawberries, fresh or frozen, plus slices to top
- 2 Tbsp cream cheese, softened
- ½ tsp lemon juice (optional, for the cheesecake tang)
- 1 Tbsp cheesecake crumb: almond flour toasted with butter and sweetener
Instructions
| 1 | Load the blender right. For one shake: yogurt, protein powder, just ¼ cup of milk, sweetener, vanilla, salt and the xanthan gum in first, ice on top. |
| 2 | Blend it thick. Blend in short bursts, tamping down between each, until it moves like soft-serve. Add milk one tablespoon at a time ONLY if it stalls — thickness is the whole point. |
| 3 | Cookies & Cream. Pulse in half the crushed sugar-free cookies at the very end — 2 pulses only, so the flecks stay visible. Spoon into a cup and top with the rest of the crumbs. |
| 4 | Peanut Butter Fudge. Blend the base with the chocolate protein, peanut butter powder and cocoa. Swirl sugar-free chocolate syrup inside the cup before filling, drizzle more on top and finish with the crumb. |
| 5 | Strawberry Cheesecake. Blend the base with the strawberries, cream cheese and lemon juice until pink and smooth. Top with the cheesecake crumb and fresh strawberry slices. |
| 6 | Serve immediately. Straws in, spoons ready — serve the trio at once, like the photo. Sludge waits for nobody: it loosens as it sits. |
Pro tips
- Frozen strawberries replace some of the ice in the cheesecake shake — even thicker.
- Xanthan gum: ¼ teaspoon is plenty. Double it and the texture goes gummy.
- Casein or a whey-casein blend powder whips thicker than pure whey isolate.
- Chill the cups for 10 minutes first and the sludge holds longer.
- For a single flavour for a crowd, the base triples cleanly in a big blender.
