Your guests will love the refreshing taste, but they will love the quirky watermelon glasses. It’s also healthy and packed with vitamins.


Expert Tips

– If you want to add your favorite soda or even alcohol like wine or prosecco, use it in place of the water in the main recipe.

– You can leave out the sugar if you prefer to have it less sweet.

– For a creamier slushie, use a bit of coconut milk.

– When choosing watermelons, look for the heaviest you can find—the heavier the watermelon, the tastier. You also want to look for a watermelon with a pale-yellow spot, this indicates that it spent some time ripening, and will therefore be sweeter. Sweet watermelons will be perfect for this recipe.

– If you don’t have watermelons, you can use strawberries as a substitute.

– Don’t have a chocolate pen? Use mini chocolate chips as the watermelon “seeds”.

Calpis is an unsweetened Japanese drink. If you cannot find it, use drinking yogurt or coconut cream.

Can I store Watermelon Slushie?

These Watermelon Slushies are best served immediately! But if you want, you can prepare them the day before. Simply cover with plastic wrap and store in the fridge. If you want to do some prep work, why not chop up your fruits and store them in the fridge until you’re ready to use them.

How to make Watermelon Slushie


Using an ice cream scoop, scoop about 8 watermelon balls. Remove the remaining watermelon flesh, add to a small bowl and set aside.

Pour a layer of kiwi mixture into each glass and refrigerate for 30 minutes.


In a small bowl, mix Calpis and gelatin until combined. Pour it on top of the green layer.


Using a melted chocolate, draw watermelon seeds on the insides of the glasses. Refrigerate for 30 minutes.


Add the watermelon in a blender and puree. Add dissolved gelatin and mix until combined.


Pour a layer of watermelon on top of the white layer. Refrigerate for 2 hours.
