3-Ingredient Coffee Banana Smoothie
This 3-ingredient coffee banana smoothie turns your morning cup into a creamy, drinkable breakfast in under five minutes. It’s what you reach for when you need both caffeine and something that feels a little more substantial than a mug.

The frozen banana does the heavy lifting, giving it a thick, milkshake-like body without a spoonful of yogurt. Toss everything in the blender and you’ve got a cold, lightly sweet latte you can honestly call breakfast.
Why This Smoothie Is a Morning Staple
I keep coming back to this one because it tastes like a coffee shop treat without the price tag or the wait. The banana’s natural sweetness softens the coffee’s edge just enough so you can skip added sugar if you want to.
The texture stays thick and frosty, so it holds up for a few minutes while you pull the rest of your day together. It’s the kind of smoothie that actually fills you up past 10 a.m., thanks to the banana and a splash of milk.
Ingredients

- 1 large ripe banana, preferably frozen: frozen gives you a thick, icy texture; a fresh banana works with a few ice cubes tossed in.
- 1 cup chilled strong brewed coffee: use your favorite roast, cooled completely in the fridge so it doesn’t melt the drink.
- ½ cup milk of choice: whole milk makes it rich, oat milk keeps it creamy and dairy-free.
- Optional: 1 tsp maple syrup or honey, ½ tsp vanilla extract, or a pinch of cinnamon.
Variations / Substitutions
- Add a scoop of protein powder: a chocolate or vanilla powder turns this into an even more filling breakfast shake.
- Go mocha: blend in 1 tbsp unsweetened cocoa powder for a chocolate-coffee combo.
- Make it vegan: use oat, almond, or soy milk and sweeten with maple syrup if needed.
- Swap in espresso: replace the brewed coffee with 1 or 2 shots of chilled espresso for a stronger, more intense kick.
If you crave something fruitier, a Mango Lassi delivers the same velvety texture without the coffee.
How to Make Coffee Banana Smoothie
Step 1: Load the Blender

Add the frozen banana chunks, the chilled coffee, and the milk of your choice into the blender. If you’re using any sweetener, vanilla, or a dash of cinnamon, toss them in now so they blend evenly. A generous splash of milk is all you need, no need to measure down to the drop.
Step 2: Blend Until Silky

Cover and blend on high speed for 30 to 45 seconds, until the mixture is completely smooth and no banana pieces are left behind. It will turn pale and thick with a light froth on top. Stop once and scrape down the sides with a spatula if everything isn’t moving right away.
Step 3: Pour and Finish

Pour the smoothie into a tall glass and, if you’d like, dust the surface with a little cocoa powder or cinnamon. Serve it straight away while it’s ice cold. A straw isn’t mandatory, but it never hurts.
A Few Quick Tips
- Freeze your banana in slices: so it blends easier. Lay them flat on a tray, then transfer to a bag once solid.
- If you only have a fresh banana, add 4 to 6 ice cubes to the blender to chill and thicken the drink.
- Double the recipe: and pour the extra into popsicle molds for a frozen coffee treat later in the week.

Frequently Asked Questions
Can I use instant coffee?
Yes. Dissolve 1 tablespoon of instant coffee granules in 1 cup of cold water and chill it fully before blending.
Do I really have to freeze the banana?
No, but the smoothie will be thinner and less cold without it. Toss in a handful of ice cubes to make up the difference.
Can I make this the night before?
The texture is best right after blending and tends to separate if it sits. You can save time by freezing banana slices and brewing the coffee the evening before.
What if I don’t want any banana at all?
You can leave it out, but the smoothie will lose its creamy thickness. A handful of oats blended with the coffee and milk gives you some body as a swap.
