Learn how to make a coffee banana smoothie with this easy recipe, made with frozen banana and coffee granules!

I'm currently dealing with a mountain of frozen bananas. Sure, you could make the best banana bread (without baking soda) with them, but smoothies will also do the trick when it comes to getting the frozen banana stash under control.
Ingredients
You don't need much to make this easy smoothie recipe!
For the smoothie
- milk and yogurt—I use a combination of 2 % milk and 2 % plain yogurt
- ice to give the smoothie some body and thickness
- frozen banana—I like to keep sliced ripe banana in the freezer for things like this, but if your banana is frozen whole, that will absolutely work too!
- coffee—I use instant coffee granules (the kind you add boiling water to when making a quick cup of coffee) but espresso powder will work too
- ground green cardamom
Fun toppings
While I topped this smoothie with espresso powder and cocoa nibs, you could try cocoa powder, shredded coconut, and so many other ingredients. Get creative!
See recipe card for quantities.
Special equipment
I tend to make my smoothies in my KitchenAid blender. Another option would be to use a stick blender and blend it directly in a large glass or jug. The KitchenAid stick blender kit comes with a large glass that can fit these ingredients.
Variations
I love the frothy layer that forms when you blend smoothies, like the milky foam of a cappuccino. This banana smoothie is so versatile and there are a lot of possible variations.
- Spices: I added cardamom to this banana drink, while thinking of Turkish coffee, which combines coffee and cardamom seeds, but you could try cinnamon, nutmeg, or even allspice for a different, warm flavour profile
- Chocolate: the coffee smoothie is topped with espresso powder, but you could try cocoa powder instead or even a splash of chocolate syrup
- Berries: one surprising flavour pairing is coffee and berries (like in this coffee raspberry bread pudding! Try adding a few strawberries or raspberries to the blender and see if you like it!
- Oats: to give the smoothie more body and to make it a better meal replacement, you can add large flake oats (also called rolled oats) and blend them in. They won't add much taste but will thicken up this smoothie and make it more substantial.
For a sweeter smoothie, add a splash of maple syrup or honey to the blender before mixing. For thicker smoothie, use less milk or add more ice cubes. For a thinner smoothie, add more milk. Smoothies are very forgiving.
Substitutions
- plain yogurt is unsweetened, but if you want more sweetness, and easy way would be to use vanilla yogurt instead or sweetened plain yogurt.
- lactose-free:
- This smoothie has a lot of dairy with lactose in it, if that's a problem, you can replace the regular milk with lactose-free milk.
- For the yogurt, there are lactose-free plain yogurt options now in stores
- vegan:
- you can try a vegan milk beverage to replace the cow's milk, like oat milk, almond milk, or even soy milk or coconut milk. Use the type of milk you like to drink.
- you can try coconut milk yogurt or even oat milk yogurt, which is slowly becoming more common and easier to find.
Each time I make this coffee and banana smoothie, I make it a little differently. Some days, I add more honey because I want it to be sweeter, other days, I add a cinnamon.
When I have some freshly brewed coffee on hand, I use it instead of the instant coffee and consequently, I reduce the milk used. If it's summer, I blend in a few ice cubes. Cocoa powder would also taste great in this recipe. The smoothie you create will be a matter of taste, but here's a recipe to get you started. And, by all means, tweak away when you make your version of this smoothie!
Storage
I prefer to make smoothies when I'm going to consume them and I prepare the quantity I'm going to drink. I find that otherwise, smoothies can separate or change colour, becoming less appealing. For this reason, I recommend making a smoothie fresh, not storing it.
If you must store a banana smoothie, put it in a mason jar, close the lid, and store refrigerate it for up to a day.

I love keeping bananas in the freezer for smoothies but I've never seen the combination of bananas and coffee. It sounds quite delicious! I wonder if leftover coffee would work. I always have about a half of a cup in the morning. Thanks for sharing this!
