Ingredients
- 1 cup unsweetened almond milk
- 1 scoop sugar-free chocolate protein powder (about 30g)
- 2 tablespoons natural peanut butter (no sugar added)
- 1 tablespoon unsweetened cocoa powder
- 1/2 avocado (makes it ultra creamy!)
- 1/2 teaspoon vanilla extract
- 1 tablespoon MCT oil (optional but great for extra healthy fats)
- 1 cup ice cubes
- Liquid stevia drops to taste (optional if you need extra sweetness)
Instructions
- Add the almond milk to your blender first (this helps prevent ingredients from sticking to the bottom).
- Add the protein powder, peanut butter, cocoa powder, avocado, vanilla extract, and MCT oil (if using).
- Add the ice cubes.
- Blend on high for 30-45 seconds until smooth and creamy. If it’s too thick, add a splash more almond milk.

Recipe Variations
Berry Chocolate Version
Add 1/4 cup of frozen raspberries or strawberries for a fruity twist. This adds about 2g net carbs but gives you an amazing chocolate-covered-berry flavor!
Mint Chocolate Version
Add 2-3 drops of peppermint extract instead of vanilla for a refreshing mint chocolate smoothie.
Extra Protein Boost
Add 1 tablespoon of collagen peptides for an extra protein boost without changing the flavor.
Coconut Chocolate Version
Use coconut milk instead of almond milk and add 1 tablespoon of unsweetened shredded coconut for a tropical twist.
Recipe Notes & Tips
- Protein Powder: Choose a high-quality, sugar-free protein powder with minimal ingredients. I prefer whey protein isolate or a plant-based option if you’re dairy-free.
- Peanut Butter: Make sure to use natural peanut butter with no added sugars. Check the ingredients – it should only contain peanuts and maybe salt.
- Make Ahead: You can prep the ingredients (except ice) in a jar the night before and store in the fridge. Add ice and blend in the morning for a quick breakfast.
- Texture Tip: The avocado makes this smoothie super creamy without any weird taste. Don’t skip it!
- Sweetness: Different protein powders have different sweetness levels. Adjust with stevia drops as needed.
Frequently Asked Questions
Can I make this smoothie without protein powder?
Absolutely! You can skip the protein powder and increase the cocoa powder to 2 tablespoons. The smoothie will have less protein but still taste chocolatey and delicious. You might want to add extra sweetener since you’ll miss the sweetness from the protein powder.
Is this smoothie truly keto-friendly?
Yes! With only 3g net carbs per serving, this smoothie fits perfectly into a ketogenic diet. The high fat content from the avocado, peanut butter, and MCT oil makes it an ideal keto meal or snack.
Can I substitute the peanut butter with another nut butter?
Definitely! Almond butter, cashew butter, or sunflower seed butter all work great in this recipe. Just make sure whatever you choose doesn’t have added sugar.
How can I make this smoothie thicker?
For an extra thick smoothie, freeze your avocado chunks beforehand or use less liquid. You can also add 1-2 tablespoons of chia seeds, which will thicken the smoothie while adding extra fiber and omega-3s.
