My Personal Experience
I made this Coffee Smoothie on one of those mornings when I was too busy to cook but still wanted something nourishing and energizing. I tossed a few things into the blender — leftover brewed coffee, protein powder, and a splash of almond milk — and I was blown away by how good it turned out. Since then, it’s become a regular in my meal prep routine.
It also works great as an afternoon pick-me-up when I want something cold, creamy, and comforting without the hassle. I’ve tried different variations — with cinnamon, vanilla extract, and even cocoa powder — and every time, it feels like a mini café experience, minus the sugar crash!
Required Equipment
🌀 Blender
A good-quality blender is essential to make this smoothie ultra-creamy and lump-free. I like using one with a small personal cup attachment — it’s perfect for single servings and super easy to clean.
🥄 Measuring Cups & Spoons
These help you stay consistent with portion sizes, especially when tracking your macros or sticking to post-op volume limits.
🧊 Ice Cube Tray (Optional)
If you prefer an extra chilled and frosty texture, adding ice cubes is a must. Pre-freezing leftover brewed coffee into cubes also intensifies the coffee flavor without watering it down.
Ingredients & Substitutions
- 1/2 cup brewed coffee (cooled) – This gives the smoothie its bold, rich base. You can also use decaf if you’re caffeine-sensitive.
- 1/2 cup unsweetened almond milk – Keeps it light and dairy-free. Swap with unsweetened soy or Fairlife milk for a higher protein option.
- 1 scoop vanilla or caramel protein powder – Adds creaminess and essential protein. Choose a low-carb, bariatric-approved brand.
- 1–2 tsp powdered erythritol or monk fruit sweetener – Optional, depending on how sweet your protein powder is.
- 1/2 tsp vanilla extract – Enhances the flavor and gives it that cozy café feel.
- 4–5 ice cubes – Optional, for a thick and frosty texture.
Substitution Ideas:
- Swap almond milk with coconut milk for a richer flavor.
- Use chocolate protein powder for a mocha-style twist.
- Add unflavored collagen peptides for an extra protein and joint-health boost.
How to Make Coffee Smoothie
- Brew and Cool the Coffee
Start with fresh brewed coffee and let it cool completely. You can even make it the night before and store it in the fridge. - Add Ingredients to Blender
In your blender, add the cooled coffee, almond milk, protein powder, sweetener (if using), and vanilla extract. - Add Ice Cubes
Toss in the ice cubes for a thicker, chilled smoothie. Adjust the number of cubes based on your texture preference. - Blend Until Smooth
Blend on high speed until everything is smooth, creamy, and well-combined. Scrape down the sides if needed. - Taste and Adjust
Give it a quick taste. Add more sweetener or a dash of cinnamon if desired. Blend again briefly. - Pour and Enjoy
Serve immediately in your favorite glass or take it on the go in a tumbler.
Tips for This Recipe
- ❄️ Use chilled coffee to prevent your smoothie from getting watered down.
- 💪 Choose a protein powder that dissolves well and doesn’t have a chalky aftertaste.
- 🧊 Pre-freeze coffee into cubes for an even stronger flavor and a frostier texture.
- 🕓 Make a double batch and store one serving in the fridge for the next day.
Optional Additions
- Cinnamon or Pumpkin Spice – Add a cozy twist for fall vibes.
- Unsweetened cocoa powder – For a mocha flavor without sugar.
- Collagen powder – Boosts protein and supports skin, nails, and joints.
- Greek yogurt (2–3 tbsp) – Adds creaminess and thickness (great if you’re farther along post-op).
Serving Ideas
- Serve it in a chilled mason jar with a straw for a café-style treat.
- Pair it with a low-carb muffin or bariatric-friendly breakfast bar.
- Enjoy it as a post-workout smoothie to refuel your energy and protein.
Storage Recommendations
- Store in the fridge for up to 24 hours in a sealed bottle or jar.
- Shake or stir before drinking if it separates.
- Do not freeze — the texture doesn’t hold up well when thawed.
Frequently Asked Questions
Can I use decaf coffee?
Absolutely! If you’re sensitive to caffeine or drinking it later in the day, decaf works just as well.
What if I don’t have protein powder?
You can add Greek yogurt or collagen powder for protein, but the flavor and texture might differ slightly.
Is it safe right after surgery?
Check with your surgeon or dietitian. If you’re cleared for caffeine and protein shakes, this should be fine.
How can I make it thicker?
Use less liquid, more ice, or add Greek yogurt or a spoon of almond butter.
