Numbers shift based on protein powder brand and how much fruit you add. Full-fat versus reduced-fat dairy also changes things. But that’s not always the case with every combination — treat this as a starting range.

Variations and Substitutions
What You Can Play Around With
No heavy cream? Coconut cream works well and adds a subtle tropical undertone that pairs nicely with raspberries or mango pieces if you’re not strictly low-carb. The texture is slightly different — a bit denser — but still good.

Chocolate protein powder instead of vanilla changes the whole character. Combine it with strawberries and it becomes something closer to chocolate-covered strawberry in flavor, which is not a bad direction.

Cream cheese softened can replace part of the cottage cheese if you want something richer and slightly more cheesecake-adjacent. About half and half works — full cream cheese replacement makes it quite heavy.

No erythritol? Monk fruit sweetener or a small amount of honey both work. Honey does add carbs but not a significant amount if used lightly.

Layers are worth trying — alternating the cream mixture with berries in a small glass looks considerably more intentional and impressive than just topping with fruit.

FAQs
Questions Worth Getting Out of the Way
Can I make these ahead? Yes, up to 24 hours in the fridge. Cover the cups with plastic wrap so the tops don’t dry out. Add fresh berries just before serving if you want them to look their best.

Which protein powder works best? A whey-casein blend tends to mix most smoothly here. Pure whey can sometimes make the texture slightly grainy depending on the brand. Plant-based powders work but may need a bit more sweetener.

Can I skip the whipped cream? Yes, but the result is denser and less fluffy — more like a thick yogurt bowl than a mousse. Still tasty, just a different experience.

My cups turned out watery — what happened? Almost certainly the frozen berries. Thaw them completely and drain off all excess liquid before adding. Fresh berries sidestep the problem entirely.

How long do these keep? Two days in the fridge, covered. After that the texture starts to break down and the berries get a bit soggy.

Conclusion
These cups exist in that useful gap between “actually satisfying” and “not going to undo your day.” They’re cold, creamy, just sweet enough, and take about ten minutes of actual effort before the fridge does the rest of the work.
