This creamy keto blueberry smoothie tastes like a treat but keeps net carbs at just 3.4g per serving. Avocado and coconut milk deliver rich healthy fats while a handful of wild blueberries adds that classic berry sweetness — all in about 5 minutes.
Ingredients
- 1 cup unsweetened canned coconut milk (full-fat)
- 1/2 cup unsweetened almond milk
- 1/3 cup frozen wild blueberries
- 1/2 medium ripe avocado
- 2 tablespoons heavy whipping cream
- 1 tablespoon chia seeds
- 1 tablespoon powdered erythritol (or to taste)
- 1/2 teaspoon pure vanilla extract
- 1/4 teaspoon ground cinnamon
- 4 to 6 ice cubes
Instructions
- 1
Add the coconut milk and almond milk to a blender first, so the blades have liquid to work with.
- 2
Add the frozen blueberries, avocado, heavy cream, chia seeds, erythritol, vanilla, and cinnamon.
- 3
Blend on high for 45 to 60 seconds, until completely smooth and the blueberries are fully broken down.
- 4
Add the ice cubes and blend again for 20 to 30 seconds, until thick and frosty.
- 5
Taste and adjust sweetness with a little more erythritol if needed, then pour into two glasses and serve immediately.
Tips & notes
- Use frozen wild blueberries rather than regular blueberries — they're smaller and lower in sugar per portion, and they keep the smoothie cold and thick.
- For extra protein, blend in a scoop of unsweetened vanilla or unflavored whey/collagen; it adds roughly 0g net carbs but will change the macros below.
- Best enjoyed fresh. If you must store it, keep in a sealed jar in the fridge up to 24 hours and shake well before drinking, as it will thicken from the chia.
