Creamy Banana Iced Coffee Recipe

Banana coffee, sometimes called banana iced coffee, is a creamy blended banana frappe — thick, dreamy, and a deliciously refreshing way to enjoy your morning coffee. Made simply with banana, coffee, and milk, it’s easy to adapt to dairy-free or vegan diets and makes a satisfying chilled treat year-round.

Banana coffee — essentially a banana smoothie with coffee

I first discovered banana coffee on a 30th birthday trip to Costa Rica. It was everywhere at cafés and smoothie trucks — especially in Nosara — and for good reason. The drink is bright, naturally sweet, and perfectly cooling in warm weather. It’s simply coffee blended with milk (dairy or plant-based) and frozen banana. That combination may sound unusual, but the flavors work beautifully together and the result is velvety and satisfying.

If you enjoy unexpected coffee pairings, another favorite is peanut butter with coffee. Try a peanut butter espresso protein shake for a rich, nutty variation.

This blended coffee makes an ideal frozen beverage for summer or any time you want a cold, caffeinated treat.

Full recipe details are provided in the recipe card further down. In short: blend frozen banana, coffee, and milk until smooth, taste, adjust, and serve.

Tools

• Blender: Any high-speed blender or personal blender will work. A blender that handles frozen fruit will create the creamiest texture.

Ingredients

• Banana: Use ripe, spotty bananas for the best natural sweetness. Slice into coins and freeze in an airtight container overnight so they’re solid — this creates a thick, creamy texture.
• Coffee: Espresso shots give the boldest coffee flavor. Cold brew or chilled brewed coffee also work if you prefer a milder taste.
• Milk: Any milk will do — dairy or plant-based (almond, oat, soy, etc.).
• Optional additions: protein powder, honey or maple syrup, vanilla extract, peanut butter, cinnamon.

Steps to make a coffee and banana smoothie

• Add milk, frozen banana, and coffee to the blender. Include any optional add-ins like protein powder or nut butter.
• Blend on high for one to two minutes, until completely smooth and velvety. Start with less milk to keep the texture thick and creamy, then add more if needed.
• Taste and adjust sweetness or coffee strength, then pour into a glass and enjoy.

Banana milk

Banana milk is a simple, nut-free, dairy-free milk alternative you can make with just bananas and water blended until smooth. Use banana milk over ice and add espresso shots for a quick banana-flavored iced coffee. Sweeten with honey or maple syrup if desired.

FAQs & Tips

• Meal prep frozen bananas: Slice ripe bananas into coins and freeze in a zip-top bag or airtight container so you always have frozen fruit ready to blend.
• Start with less milk and add more to reach your preferred thickness — this keeps the drink creamy rather than thin.
• Try different coffee bases. Espresso yields the strongest coffee flavor, while cold brew or chilled brewed coffee produces a subtler taste. Use what you enjoy most.

Recipe variations

• Stir in a spoonful of homemade Nutella to make a hazelnut banana coffee shake.
• Add a chocolate protein scoop and an electrolyte packet for a chocolatey, replenishing version.
• Try a pinch of cinnamon and nutmeg for warm spice notes.
• Use a flavored nondairy creamer for extra richness and flavor.
