Why This Coffee Smoothie is Different
If you love a good iced coffee and also crave a quick breakfast or post-workout shake, this coffee smoothie checks every box. Unlike sugary store-bought options or overly complicated smoothie recipes, this one is blended with intention.
It’s made with wholesome pantry staples, naturally sweetened, and totally customizable to your taste. Plus, I’ve tested this recipe more times than I’ll admit publicly—and it’s the one I return to every time I need a nutritious energy boost that actually tastes like dessert.

Why Trust This Recipe?
Hi! I’m a professional recipe developer, food stylist, and lifestyle expert. I’ve worked with top food brands to create recipes that are approachable, seasonal, and actually work in your kitchen.
My readers come to me for easy, everyday recipes that taste elevated without requiring a dozen specialty ingredients. I test each recipe (including this coffee smoothie) thoroughly so that what you see here is the real deal—tried, tested, and smoothie-sipping approved.
The Story Behind This Coffee Smoothie
This smoothie was born out of busy mornings where I needed coffee and breakfast—and only had time for one. I started blending brewed coffee with frozen banana and a splash of oat milk and slowly evolved it into the ultimate coffee + protein smoothie hybrid.
Now, it’s one of my most popular smoothie recipes with friends, clients, and anyone who’s tried it. And honestly? It tastes like a creamy coffee milkshake but keeps you full and focused for hours.
Ingredients You’ll Need
Here’s what you’ll need to make this healthy coffee smoothie recipe:
- 1 frozen banana – Adds creaminess and natural sweetness (no ice needed).
- ¾ cup brewed coffee – Use chilled brewed coffee or your favorite cold brew for a stronger coffee flavor.
- ¼ cup oat milk – You can swap in almond milk, coconut milk, or dairy if you prefer.
- 2 tbsp peanut butter – For protein, healthy fats, and that classic PB flavor. Almond butter works too!
- 1 tbsp maple syrup (optional) – I find the banana usually makes this sweet enough, but it’s a great option if you want more of a treat.
- 1 scoop protein powder – Use your favorite protein powder to turn this into a balanced protein coffee smoothie.
Optional Add-ins: A pinch of cinnamon, a spoonful of cocoa powder for a mocha twist, or a few hemp seeds for an extra boost.
Variations and Substitutions
You can easily adapt this coffee smoothie based on what you have or your flavor preferences:
- No banana? Use frozen cauliflower or avocado for creaminess.
- Vegan version: This recipe is already dairy-free—just be sure your protein powder is vegan too.
- No protein powder? Add ¼ cup Greek yogurt for extra creaminess and protein.
- Low sugar? Skip the maple syrup or sub with stevia or monk fruit.
- Mocha vibe? Add 1 tsp cocoa powder to turn it into a chocolate coffee smoothie.

Tip
Chill your coffee ahead of time or use cold brew for the best texture.
Expert Tips for the Perfect Smoothie
Use a frozen banana – This is the key to a thick, milkshake-like texture without adding ice.
Chill your coffee – Hot coffee can melt everything and make your smoothie watery.
Choose a quality protein powder – For a protein coffee smoothie, make sure it blends well and complements the flavor (vanilla or chocolate both work great).
Double the recipe – Store leftovers in the fridge for up to 24 hours, though the texture is best right after blending.
How to Store + Meal Prep
You can make a batch of the base (everything except the banana) and store it in a mason jar in the fridge. Just add the frozen banana and blend when ready. You can also freeze pre-portioned smoothie ingredients in zip-top bags for a grab-and-blend option!
