Your weekend treat is right here!
A looong time, like ages ago, I shared this frozen coconut mojitos. They continue to be a really popular recipe here on the blog each summer, and I can attest to how delicious they are. They are light and fresh and cold and icy and perfect for hot summer days.
Even the last few years when it’s been all about frosé, I’ve often thought about my frozen coconut mojitos and wanted to make them for parties! Since they are frozen and made in the blender, it’s easy to make a big batch at once. We all love ‘em.
So enter… frozen watermelon mojitos!
This recipe came about by accident. I had a huge bowl of watermelon cubes on my counter. Every week in the summer I cut up a ton of fruit for us. Melons, berries, cherries – the list goes on. My kids adore fruit and it’s an easy snack to always have on hand.
This time, the watermelon I ended up with was HUGE. I barely had room in the fridge for it so I stuck the extra watermelon cubes in the freezer. And then it hit me!
USE THESE FOR A COCKTAIL!
I’ve made wine ice cubes before and of course we all know about coffee ice cubes. I loved the idea here of using actual frozen watermelon to blend into a drink without watering it down – whether it’s alcoholic or not.
And I’ve done this with frozen coconut that I’ve found at Trader Joe’s and Whole Foods before too. It’s great!
There is an abundance of fresh mint in my herb garden – or should I say, taking over the herb garden. As usual. So I made a mint simple syrup. I threw the fresh mint leaves right into the blender too, which is why you can see little specks in the frozen drink.
Fresh lime juice is also key! Squeeze it in and blend.
When it comes to rum, I suggest a white rum here, or you can use coconut rum too. I made this both ways and even though we love coconut rum, I still didn’t find the coconut to be too overpowering here. Depends on what you like! But definitely use one of those – nothing dark or spiced, of course.
Finally, I still added some seltzer right into the blender to finish this off! Yes, adding bubbly soda to the blender may be playing with fire but it was perfect and needed.
Top the glass off with limes, more mint, maybe a straw for easy sipping!
If you want to make a mocktail version of this, I suggest just using the watermelon, fresh lime juice, simple syrup and club soda. Simply leave out the rum!
Either version is so refreshing and easily my new favorite thing!
Frozen Watermelon Mojitos
Frozen Watermelon Mojitos
Ingredients
- 2 ½ cups watermelon cubes, frozen
- ½ cup white or coconut rum
- ⅓ cup freshly squeezed lime juice
- ¼ cup mint simple syrup, recipe below
- ½ cup seltzer water, you could use lime or watermelon flavor here too!
- lime wedges for garnish
- fresh mint leaves for garnish
mint simple syrup
- 1 cup water
- 1 cup sugar
- 1 handful of fresh mint leaves
Instructions
mint simple syrup
- To make the mint simple syrup, add the water, sugar and fresh mint leaves to a saucepan and heat over medium heat. Whisk constantly until the sugar dissolves and the mixture comes to a boil. Let it bubble for a minute or so, then reduce the heat and let it cool completely. If I make it before, I’ll usually put it in a bowl or jar, let it come to room temperature then stick it in the fridge overnight. I do like to let it cool completely before adding it to the blender. This will make extra, so you can store it in the fridge. You can use it in coffee or cocktails!
watermelon mojitos
- Make sure to freeze the watermelon cubes for at least 6 hours, or even overnight.
- Combine the watermelon cubes, rum, lime juice and mint syrup in a high powered blender. Blend until combined. Add in the seltzer and blend again. Taste and if you would like it to be sweeter, add more mint syrup.
- Pour in a frosted glass and garnish with fresh mint and lime wedges.

This is great timing, I was wanting something watermelon, not necessarily adding alcohol. Wish I had a watermelon! My mint spread more & more each year until we dug it out & put some in a pot. Last fall we sunk the pot in the ground for winter & pulled it back out this spring! I’m in Pittsburgh too, so remember this in case your mint gets too aggressive:)
This recipe is really amazing. Thanks for the sharing.

Hi, can I substitute the frozen watermelon for frozen pineapple? Thanks
These are delicious! So refreshing and summery. I love.
So I forgot I don’t have a blender, so I used my mini food processor for the frozen watermelon, and then I just mixed everything in a cocktail shaker and decided to strain out the mixture since I already had everything in the shaker anyway. I made this for my husband and he said it was good and tasted of watermelon, he didn’t detect the mint as much so I’ll try increasing that for next time.
This was so delicious! My entire family loved it. I was surprised how well the mint and watermelon paired. Also, freezing the watermelon allows you to have one last taste of summer after watermelon season has passed. Thanks so much!!
