Kiwi Watermelon Smoothie with Coconut Milk
This watermelon kiwi smoothie takes just four ingredients and less than a minute in the blender. Juicy watermelon and bright, tangy kiwi blend with vanilla coconut milk and ice into a cool, refreshing drink.
It is light, naturally sweet from the fruit and perfect for hot days when watermelon is at its best.

The Best Kiwi Watermelon Smoothie (Just 4 Ingredients)
I love smoothies, and this one is about as simple and refreshing as they come. Two cups of watermelon chunks, two peeled kiwis, a cup of vanilla coconut milk and a cup of ice are all it takes.
Watermelon is mostly water, so it blends into a light, juicy base that tastes like summer. On its own it can be a little one note, and that is where the kiwi comes in. Kiwi adds a bright, tangy flavor and a lovely tropical sweetness, and its tiny black seeds give the smoothie little flecks of color.
Vanilla coconut milk ties the two fruits together. It adds a creamy touch and a hint of vanilla without making the smoothie heavy, and it keeps the whole drink dairy free. A cup of ice makes it frosty and thick enough to sip slowly on a hot afternoon.
There is no added sugar and no protein powder or yogurt, so the fresh fruit really shines. It is the kind of smoothie you can blend for breakfast, an afternoon pick me up or a cool treat after time outside, and it goes from blender to glass in under a minute.

Ingredients You’ll Need
Here is what goes into this watermelon kiwi drink and why each one is there. Exact amounts are in the recipe card below.
- Vanilla coconut milk: The creamy base. Use the drinkable coconut milk sold in cartons, not canned coconut milk, which is much thicker and richer. The vanilla flavor adds a soft sweetness that rounds out the tart kiwi. Unsweetened vanilla or plain coconut milk also works, and almond milk is an easy swap. Give the carton a good shake first, since coconut milk can settle.
- Watermelon: The star of the smoothie. Pick a melon that feels heavy for its size and has a creamy yellow spot where it rested on the ground, both signs of a ripe, sweet watermelon. Seedless watermelon is easiest. If yours has black seeds, pick out what you can before blending. Cut it into chunks so it measures easily and blends quickly. Leftover cut watermelon keeps covered in the fridge for a few days, so you can blend another smoothie later in the week.
- Kiwi: Two kiwis, peeled. Ripe kiwis give slightly when you gently press them, like a ripe peach. Firm kiwis taste sour, so let them sit on the counter for a day or two if they are hard. Peel them with a vegetable peeler, or cut off the ends and scoop the fruit out with a spoon. Golden kiwi is a sweeter, less tangy swap with smooth, hairless skin.
- Ice: One cup makes the smoothie cold and thick. Add more ice for a thicker consistency. You can also freeze some of the watermelon chunks ahead of time and use them in place of part of the ice, which keeps the flavor from getting watered down.
How to Make a Watermelon Kiwi Smoothie
- Prep the fruit. Cut the watermelon into chunks, trimming away all of the green rind and pale white flesh, and remove any black seeds. Peel the kiwis and cut them in half so they blend evenly. Measure the watermelon loosely packed, with no need to squash the chunks into the cup.
- Load the blender in order. Place the ingredients in the blender in the order listed: vanilla coconut milk first, then the watermelon, the kiwi and the ice. Liquid on the bottom helps the blades start spinning freely, and the ice on top gets pulled down into the fruit.
- Blend on high. Blend on high for 30 to 45 seconds, until the smoothie is completely smooth and no chunks of ice or fruit remain. You’ll see the kiwi seeds spread evenly throughout as little dark flecks. Avoid blending much longer, since the heat from the motor can start to melt the ice.
- Check the thickness. For a thicker consistency, add more ice and blend for a few more seconds. If it is too thick, add a splash of coconut milk. Taste it too. If your kiwis were very tart, a little more watermelon will balance it out.
- Serve right away. Pour into glasses and enjoy it cold, with a kiwi slice on the rim if you like. Watermelon smoothies taste best fresh, before the ice melts and the fruit starts to separate. Chilled glasses help it stay frosty a little longer.
Kami’s tip: Put the ingredients in the blender in the order listed and blend on high for 30 to 45 seconds. If you like your smoothie thicker, just add more ice.
Ways to Customize Your Smoothie
- Freeze the watermelon. Use frozen watermelon chunks in place of some of the ice for a thicker, more flavorful smoothie.
- Add a banana. Half a banana makes it creamier and a little sweeter.
- Brighten it up. A squeeze of lime juice or a few mint leaves makes it even more refreshing.
- Swap the milk. Almond milk or plain coconut milk work in place of vanilla coconut milk.
Watermelon Kiwi Smoothie FAQs
- Do I need to peel the kiwi? The recipe calls for peeled kiwi, which gives the smoothest texture. Kiwi skin is edible, but it is fuzzy and can leave bits in your glass. A spoon makes peeling ripe kiwis quick.
- Can I use canned coconut milk? It will make a much thicker, richer smoothie. The recipe is meant for the drinkable coconut milk sold in cartons.
- Can I use frozen fruit? Yes. Frozen watermelon or kiwi both work. Use less ice so the smoothie doesn’t get too thick, and add a splash more milk if the blender struggles.
- Is this smoothie dairy free? Yes. It is made with coconut milk and has no yogurt or dairy.
- How do I make it thicker? Add more ice, or use frozen watermelon chunks in place of some of the ice.
- Can I make it ahead? It is best fresh. You can keep it covered in the fridge for up to 24 hours. Stir or shake it before drinking, since it will separate.
- What if my watermelon has seeds? Pick out the black seeds before blending. Seedless watermelon is the easiest choice. The small white seeds in seedless melons are soft and blend right in.
