Keto Chocolate Banana Smoothie
Ingredient Notes (Detailed Explanation of Each Ingredient)
Unsweetened Almond Milk
Almond milk is a staple in keto recipes because it’s naturally low in carbohydrates and calories. Unsweetened versions typically contain 1–2 net carbs per cup, making them ideal for smoothies. It provides a light, nutty base without overpowering other flavors.
Substitute: Unsweetened coconut milk or macadamia milk.
Heavy Whipping Cream
Heavy cream adds richness, thickness, and healthy fats to the smoothie. Fat is essential on keto because it helps keep you full and supports ketosis. It also enhances the creamy mouthfeel that traditional banana smoothies are known for.
Unsweetened Cocoa Powder
Cocoa powder delivers deep chocolate flavor without sugar. It’s rich in antioxidants and very low in net carbs when used in moderation. Always choose 100% unsweetened cocoa powder to stay keto-compliant.
Keto-Friendly Chocolate Protein Powder (Optional)
This ingredient boosts protein content, making the smoothie more filling and suitable as a meal replacement. Choose a protein powder sweetened with stevia or monk fruit and free from maltodextrin or sugar alcohols like maltitol.
Banana Extract (Low-Carb Alternative)
This is the star ingredient. Banana extract provides authentic banana flavor without the carbs found in real bananas. A small amount goes a long way, so start with less and adjust to taste.
Important: Always check labels to ensure there’s no added sugar.
Powdered Erythritol or Monk Fruit Sweetener
These zero-glycemic sweeteners add sweetness without affecting blood sugar levels. Powdered versions dissolve more easily in cold smoothies, preventing graininess.
Almond Butter or Peanut Butter (Unsweetened)
Nut butter adds thickness, healthy fats, and a subtle nutty flavor that pairs beautifully with chocolate and banana notes. Make sure it’s unsweetened and free from added oils or sugars.
MCT Oil or Coconut Oil
These fats provide quick energy and help increase ketone production. MCT oil is especially popular in keto diets for mental clarity and sustained energy.
Vanilla Extract
Vanilla enhances both chocolate and banana flavors, creating a well-rounded taste profile. Use pure vanilla extract for best results.
Salt
A small pinch of salt balances sweetness and enhances overall flavor. It also helps replenish electrolytes, which is important on keto.
Ice Cubes
Ice thickens the smoothie and gives it a refreshing, milkshake-like texture. Adjust the amount depending on how thick you prefer your smoothie.
Serving Instructions
- Serve immediately for best texture and flavor.
- Garnish with a sprinkle of cocoa powder or shaved dark chocolate (keto-approved).
- Enjoy as:
- A keto breakfast
- Post-workout shake
- Dessert smoothie
- Afternoon energy boost
Tips
- Start with less banana extract; it’s very strong.
- Use powdered sweeteners to avoid a gritty texture.
- Freeze almond milk in ice cube trays for extra creaminess.
- Add avocado slices for more thickness and healthy fats.
- If too thick, add a splash of almond milk.
Storage Information
- Best consumed fresh
- Can be stored in an airtight container in the refrigerator for up to 24 hours
- Shake or re-blend before drinking
- Not recommended for freezing due to texture changes
