A bit difficult to dissolve for shakes but is brilliant to make protein pudding dessert! *by G***3 on 20 June 2013* My first attempt to make a protein shake with this Casein powder wasn't very successful, as it doesn't dissolve as well as whey protein, even with a shaker (I found that mixing it first in a bowl/glass with a small amount of liquid then adding more liquid is easier to dissolve it properly. I actually took advantage of the thick-high absorbing properties to use it to make protein pudding, with the following proportions: 20g of casein powder, 70ml of unsweetened almond milk (or other milk), 50g of fat-free yogurt, 3g of unsweetened cocoa powder, 5g of peanut butter, mix well and chill in the fridge for 30min at least, it will get smoother and thicken even more resulting in a delicious chocolate peanut butter mousse/pudding. It tastes like an indulgent dessert for only150kcal : 21g protein, 6g carbs of which 3g of sugar, 4g of fat (good unsaturated fat from the peanut butter). Being low in sugar, it's healthier than most desserts and it has also replaced my usual chocolate fix! I agree with another customer on a kind of "cappuccino"-like smell of the dry powder, but once dissolved the chocolate taste is nice. I have also tried the vanilla as a sample, which tastes like vanilla ice cream. Both are properly sweetened for most people taste I think, however I have cut my sugar consumption for the past two months and being more sensitive to any sweetness, I now find it a bit too sweet to my taste, but I will keep buying it anyway. ## Frequently Bought Together - Optimum Nutrition Gold Standard 100% Micellar Casein Protein Powder, Slow Digesting, Helps Keep You Full, Overnight Muscle Recovery, Chocolate Supreme, 2 Pound (Packaging May Vary) - Optimum Nutrition Gold Standard 100% Whey Protein Powder, Double Rich Chocolate, 2 Pound (Packaging May Vary) - Optimum Nutrition Micronized Creatine Monohydrate Powder, Unflavored, 60 Servings, 300 Grams (Packaging May Vary) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/702109646-optimum-nutrition-gold-standard-casein-slow-digesting-protein-powder-zinc](https://www.desertcart.kg/products/702109646-optimum-nutrition-gold-standard-casein-slow-digesting-protein-powder-zinc) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-09-27*
