How To Make Keto Protein Shake

Making this protein shake is super easy, you just need a blender!


  • Almond Milk – Prefer unsweetened, unflavored almond milk. You can use vanilla almond milk if your protein powder is vanilla flavored to boost the taste.
  • Greek Yogurt – Pick unsweetened Greek yogurt, it’s keto-friendly. For a dairy-free version, choose unsweetened coconut yogurt. You can also use some heavy cream instead.
  • Protein Powder – You can use any flavor of low-carb protein powder you love. Chocolate protein powder is my suggestion but vanilla or unflavored protein powder works as well.
  • Almond Butter – Use natural almond butter made with only almonds. Avoid any nut butter with sugar or oil.
  • Crystal Sweetener – My preference is crystal erythritol. You can also use xylitol, allulose, or tagatose. Learn how to pick your keto sweetener.

Combine all the ingredients in a high-speed blender. The order doesn’t really matter but if your blender isn’t super fast, start with the almond milk.

This will avoid lumps of protein powder stuck to the bottom.

Blend on the high-speed setting until the keto shake mixture is smooth.

Adjust the frothiness to your liking by adding more ice cubes to make it frothier or more almond milk to make it runnier.

Keto Protein Shake


You can boost this low-carb protein shake flavors by adding:

  • More Erythritol – to boost the sweetness. In fact, protein powder brands vary in sweetness and depending on your brand, you may need to add more or less sweetener to fit your tastebuds.
  • Unsweetened Cocoa Powder – add 1 to 2 teaspoons to add a chocolate flavor to the shake.
  • Frozen Fruits – you can boost the creaminess of this sugar-free protein shake by adding low-carb frozen fruits like raspberries, blueberries, or boysenberries. Fruits mary better with vanilla protein powder than chocolate protein powder.
  • Frozen Vegetables – frozen cauliflower rice or frozen zucchinis are great thickeners in keto smoothies and shakes.
  • More Protein Powder – it’s up to you to add more protein to your shake by increasing the collagen powder. Note that this thickens the drink, so you may need more unsweetened almond milk to achieve a great texture.
  • More Ice Cubes –  To make the shake icy and forthier.
  • Chia Seeds – you can add a pinch of chia seeds to add antioxidants.
  • Coconut Oil – you can also add a touch of coconut oil or MCT oil to get all the benefits of medium-chain triglyceride.

Allergy Swaps

If you have allergies or want a vegan version, you can make the following changes.

  • Dairy-Free Option – Replace the yogurt with dairy-free low-carb yogurt. Unsweetened coconut yogurt is a great keto yogurt option because it’s high in fat and made from coconut cream.
  • Nut-Free: Replace the Almond Milk with an unsweetened nut-free alternative such as coconut milk and the almond butter with a seed butter such as sunflower seed butter.
  • Vegan: Use the dairy-free option and make sure to pick a low-carb vegan protein powder instead of collagen or whey protein powder.

  • In a blender, add all the ingredients. The order doesn't matter, but start with only 1 tablespoon of erythritol and increase later if needed based on the sweetness desired. Some keto protein powders are already sweetened, and you may not need any sweetener.
