As you may have noticed, my recipes have an increasing focus on protein. After doing a huge amount of research for my upcoming book, The Protein Advantage, I believe this is very important for healthy aging. So I have been creating a lot more low-carb high-protein recipes. And this delicious peanut butter frosty is a seriously tasty way to increase consumption of that vital nutrient!
My longtime fans and followers know just how much I adore the chocolate peanut butter combo. I work it into so many recipes like Keto Protein Balls and the famous Keto Peanut Butter Bars. So I was delighted when I discovered that Just Ingredients has a delicious Peanut Butter Chocolate protein powder. I thought it would be perfect for a delicious protein shake.

Ingredient Notes
- Cottage cheese: This helps give the frosty a thicker consistency. You could also use ricotta cheese.
- Peanut butter: I always use a creamy all-natural peanut butter. You can use almond butter or any nut or seed butter.
- Protein powder: I do recommend trying Just Ingredients, but I know not everyone can get hold of it. Read the Protein Options below for alternatives.
- Cocoa powder: You don’t need much additional cocoa to give it a frosty-like flavor.
- Low carb milk: I usually use unsweetened almond or hemp milk, but any kind of low carb “milk” works here.
- Heavy cream: A touch of heavy cream adds additional creaminess.
- Sweetener: This recipe doesn’t rely on a specific sweetener for consistency, so feel free to use your favorite.
Tips for Success
As with most smoothies and shakes, it’s really a matter of dumping all of the ingredients into a blender and turning it on. But I do have a few tips for you to get a super smooth, creamy consistency.
Use crushed ice. I find that starting with ice that’s already in small pieces helps create a smoother consistency. But what do you do if your refrigerator only dispenses full ice cubes? My new fridge doesn’t have a crushed ice setting so I actually blend the cubes on their own first, before adding any other ingredients. A few quick seconds and I have nicely crushed ice!
Add the thickest ingredients first: Getting a shake or smoothie of any kind to blend up nicely requires the ingredients to go in a certain order. Once I have the crushed ice in there, I add the cottage cheese and peanut butter, then the protein powder and cocoa. The liquid goes in last, as it will seep down among the other ingredients.
Blend and scrape, blend and scrape: Stop the blender a few times and scrape down the sides with a small silicone spatula (like this one – so useful, I have about 10 of them in my baking drawer!). This helps ensure that the peanut butter or cottage cheese get properly mixed in.
Protein Options
While I really love the Peanut Butter Chocolate protein powder for this recipe, it’s not a requirement. If you have a chocolate protein powder you love, you can use that instead. Use the appropriate serving size based on the powder you choose.
You can also use plain or vanilla protein powder. If using plain, you will need to add more cocoa powder and some more sweetener. I recommend another half tablespoon of cocoa powder (so 1 tablespoon in total) and 1 tablespoon of sweetener. Then taste and adjust as you see fit.
