This energizing coffee smoothie transforms your leftover morning brew into a nutritious, dessert-like treat that's perfect for both pre-workout fuel and afternoon pick-me-ups. The combination of frozen banana, dates, and coffee creates a naturally sweet, creamy texture without added sugars.
I discovered this recipe during my marathon training days when I needed something to power me through long runs without weighing me down. Now it's my go-to recovery drink that satisfies both my coffee cravings and sweet tooth simultaneously.
Ingredients
- Frozen banana slices: The frozen banana creates the creamy base and natural sweetness while providing potassium for muscle function
- Leftover coffee: Use whatever strength you prefer; cold brew works beautifully for a smoother taste
- Almond milk: Adds creaminess without heaviness; try refrigerating beforehand for an extra cold smoothie
- Almond butter: Provides healthy fats and protein that balance the carbohydrates from fruit
- Ice cubes: Adjust quantity based on how thick you prefer your smoothie
- Medjool dates: These caramel-like dates add complex sweetness and sustained energy from natural sugars
- Cauliflower: Completely undetectable veggie boost that adds fiber and nutrients without affecting flavor
- Sea salt: Enhances all the flavors and balances sweetness; use flaky salt for best results
- Cacao nibs: Optional but adds delightful chocolate crunch and antioxidants on top
Step-by-Step Instructions
- Prep Ingredients:
- Ensure your banana is properly frozen; slice it at least 4 hours before or overnight for best results. The smaller the slices, the easier blending will be. Pit your dates and break them into smaller pieces to help them blend completely.
- Layer Your Blender:
- Place ingredients in your blender in this order: liquid ingredients (coffee and milk), then soft ingredients (dates and almond butter), followed by frozen items (banana, cauliflower, and ice). This layering method prevents air pockets and ensures smooth blending.
- Blend To Perfection:
- Start blending on low speed for 15 seconds, then gradually increase to high speed and blend for 45-60 seconds until completely smooth. If your blender struggles, pause blending and use a spatula to push ingredients towards the blades before continuing.
- Serve Immediately:
- Pour into a tall glass and sprinkle with cacao nibs if desired. The smoothie is best enjoyed right away when the texture is perfect. Sip slowly to appreciate the complexity of flavors from the coffee, dates, and banana.

This smoothie became my secret weapon during a particularly grueling training season. The combination of quick carbs from the banana and dates paired with the steady energy from almond butter kept me going for miles. Now my training partners all request it before our long Saturday runs.
Making Ahead & Storage
Prepare components in advance by keeping a stash of sliced bananas in your freezer at all times. You can also pre-portion other ingredients (except liquid) into small containers or bags for grab-and-blend convenience. While best fresh, the smoothie can be stored in an airtight container in the refrigerator for up to 8 hours; shake well before drinking as separation is natural.

Customization Options
The beauty of this recipe lies in its flexibility. Swap the almond butter for peanut or cashew butter for different flavor profiles. Replace almond milk with oat milk for extra creaminess or coconut milk for tropical notes. Add a scoop of your favorite protein powder to make it more substantial after workouts, or a tablespoon of cocoa powder for a mocha variation. During summer months, frozen cauliflower rice can replace ice cubes for extra nutrition without dilution.
Perfect Pairings
This smoothie complements savory breakfast options beautifully; balance its sweetness with avocado toast or a breakfast burrito. For a complete post-workout recovery meal, pair with a small handful of nuts and dried fruit. The smoothie also works surprisingly well alongside simple desserts, offering a coffee-like accompaniment to a single cookie or small brownie without overwhelming sweetness.
Frequently Asked Questions
- → Can I use fresh banana instead of frozen?
Yes, you can use fresh banana, but frozen banana creates a creamier, thicker texture. If using fresh, add a few more ice cubes to achieve similar consistency.
- → Why add cauliflower to a coffee smoothie?
Cauliflower adds extra nutrients and fiber without significantly altering the flavor. It creates creaminess while keeping the smoothie lower in calories and sugar than using only fruit.
- → Can I substitute the coffee with something else?
Absolutely! For a caffeine-free version, use chicory coffee, dandelion coffee, or cacao. For a different caffeine source, try matcha or chai tea instead.
- → What if I don't have almond butter?
Any nut or seed butter works well - try peanut, cashew, sunflower seed, or even tahini. Each will add a different subtle flavor profile while maintaining the creamy texture.
- → How long will this smoothie keep?
This smoothie is best enjoyed immediately after blending for optimal texture and flavor. If needed, it can be stored covered in the refrigerator for up to 24 hours, though separation may occur (just re-blend or shake before drinking).
- → Can I make this smoothie ahead of time?
You can prepare smoothie packs by combining all ingredients except the liquids in freezer bags. When ready to enjoy, simply add the coffee and almond milk to the blender with your frozen ingredient pack.
