When I need something quick, filling, and chocolatey, this high-protein smoothie is one of my go-to recipes. It’s thick, creamy, and easy to make with just a handful of ingredients.
Unlike most smoothies that are loaded with sugar, this one is keto-friendly and balanced to keep you full for hours. With nearly 40 grams of protein per serving, it’s a great option for breakfast, post-workout recovery, or even an afternoon pick-me-up.
Why You’ll Love This High-Protein Chocolate Smoothie
- Quick & easy – Ready in 5 minutes with simple ingredients.
- High in protein – Nearly 40 grams per serving to keep you satisfied.
- Keto-friendly – Low in carbs and sugar-free.
- Rich & creamy – A thick chocolate shake texture without the guilt.
- Versatile – Works as breakfast, post-workout fuel, or a healthy snack.
Ingredients & Swaps
- Protein powder – Use unsweetened chocolate whey or egg white protein powder. For a dairy-free/vegetarian option, try plant-based chocolate protein.
- Almond butter – Adds creaminess and healthy fats. Swap with peanut butter or cashew butter. Use or coconut butter (aka coconut manna) or sunflower seed butter for nut-free.
- Greek yogurt – Thickens the smoothie and adds extra protein. Use coconut yogurt for a dairy-free alternative.
- Almond milk – Unsweetened is best to keep carbs low. Any nut or seed milk will work.
- Cocoa powder – Use unsweetened cocoa (Dutch process) or cacao powder for a rich chocolate flavor.
- Optional sweetener – If you like it sweeter, add stevia, monk fruit, or allulose.
- Ice cubes – Make the smoothie extra thick and refreshing.

Do I have to use protein powder?
Not strictly, but it’s what makes this smoothie high in protein. If you’d rather skip it, add more Greek yogurt or even cottage cheese to boost protein content.
What sweetener works best?
This smoothie is naturally chocolatey but not very sweet. If you like a sweeter taste, add a little allulose, stevia, or monk fruit. Allulose will blend in smoothly without the cooling aftertaste erythritol sometimes has. My favorite allulose brand is RxSugar - click here to get 20% off RxSugar.
Is Zero-Fat Yogurt Keto?
Yes. Zero-fat or Skyr-style yogurt can fit into a keto diet because it’s naturally low in carbs and still creamy. Just like lean cuts of meat (chicken breast, cod, fillet steak), low-fat dairy is fine on keto.
Why use low-fat yogurt? Keto isn’t about piling on fat — it’s about controlling carbs and eating the right amount of fat for your goals. For weight loss, lower fat options like Skyr can help reduce calories while keeping protein high. For maintenance or weight gain, higher fat dairy may work better.
Storage & Make-Ahead
This smoothie is best served right after blending, while it’s thick and creamy. If you need to make it ahead, store it in a sealed jar or bottle in the fridge for up to 24 hours. Shake or re-blend before drinking, as it may separate slightly.
For meal prep, portion out the dry ingredients (protein powder, cocoa, optional sweetener) into small containers. When ready, just add almond milk, yogurt, and nut butter, then blend with ice.
