Ingredients
Here are the simple low-carb banana smoothie ingredients:
- Unsweetened Almond Milk: Be sure to use almond milk instead of cow's milk to keep the carbs low. I prefer vanilla almond milk for added flavor.
- Heavy Whipping Cream: Makes the sugar-free banana smoothie extra rich and creamy and makes it taste like a milkshake!
- Keto Orgain Vanilla Collagen Powder: My very favorite low-carb protein powder. It only has three net carbs and tastes like a legit vanilla shake!
- Banana Extract: Banana flavor without the carbs!
- Ice Cubes: Aids in the texture.
- Xanthan Gum: Keeps the shake from being frothy and slightly thickens it.
- Ground Cinnamon: Adds depth of flavor.
- Allulose: Sugar-free sweetener that dissolves well and has NO aftertaste! I don't usually add allulose to my smoothie (which is why it's not in the picture), but if you prefer smoothies on the sweet side, feel free to add some!
Frequently asked questions
A medium banana has roughly 27 carbs and 24 net carbs. Since many keto diets only allow around 30 carbs, bananas are not considered keto-friendly.
To make a low-carb banana smoothie, use banana extract instead of a banana for the delicious flavor without the carbs.
Low-carb smoothies can be thickened with ice, xanthan gum, yogurt, chia seeds, or avocado (avocado will turn light-colored smoothies green!). I recommend Two Good Yogurt because it tastes great and is low in carbs. Be aware that I haven't tested yogurt, chia seeds, or avocado in the recipe below 👇
Milkshakes are usually ice cream-based and are more of a rich and decadent dessert, while smoothies may contain fruit, vegetables, or yogurt and are considered a healthier option. However, even though this recipe is a smoothie, it tastes rich and decadent like a milkshake!
Easy instructions
Add all the ingredients to a blender jar and blend until smooth. I use a Blendtec, but no special blender is needed. Just use whatever you have!
Add almond milk if the keto shake is too thick or ice if it's too thin.
Variations
Here are some fun variations for your sugar-free banana smoothie. Remember that the variations may change the nutrition information and carb count.
- Peanut Butter: Add two teaspoons of almond butter or peanut butter for a peanut butter banana smoothie.
- Green Smoothie: Add a small handful of mild greens, such as spinach or kale.
- Bulletproof: Add MCT oil or butter.
- Strawberry Banana: Add a small handful of frozen, chopped strawberries.
Substitutions
- While I prefer the Orgain Collagen Powder, you can use any low-carb vanilla protein powder you like. Since all powders are a bit different, you may need to add some sweetener or adjust the amount of ice and xanthan gum to reach your desired thickness.
- The heavy whipping cream can be replaced with more almond milk, but it won't be as rich and creamy.
- For dairy-free, replace the heavy whipping cream with full-fat canned coconut milk.
Top tip
- Don't over-blend your smoothie, or the heavy whipping cream might start turning into whipped cream!
