Blackberry Mojito

I learned how to make this blackberry mojito from a bartender friend many years ago, and it’s been my go-to way to make mojitos ever since. I love how simple it is and how it stays light and balanced instead of overly strong. The combination of fresh blackberries, lime, and mint feels bright and clean, and it comes together in about ten minutes, which makes it perfect for a hot afternoon or when guests come over.

And look at just how pretty this drink is!

Why you’ll love this recipe

• It’s quick to make and flexible—you can strain it or leave it rustic, use different berries, or switch up the herbs.
• The blackberry flavor is fresh, not syrupy.
• It stays balanced, not boozy. The blackberry, lime, and mint shine without the rum overpowering the drink.
• Easy to scale for guests, but just as good when you’re making one for yourself.

Key ingredients & how I use them

• Blackberries: I gently muddle them just enough to release their juice without turning them bitter.
• Fresh mint: pressed, not crushed — bruising the leaves releases flavor without overpowering the drink.
• Lime juice: I only use fresh lime juice here. Bottled lime flattens the flavor and can make the drink taste harsh.
• Simple syrup: I prefer it over granulated sugar because it dissolves instantly and keeps the texture smooth.
• White rum: I stick with white rum because it keeps the drink light and lets the blackberry and lime shine without competing.
• Club soda: Cold, plain soda water is best. It adds lift and freshness without changing the flavor balance.

How to Make a Blackberry Mojito

The full printable recipe is below, but here’s how I make it step by step.

You can use a bowl, a jar, or a cocktail shaker. I like to use a cocktail shaker because I like my mojito shaken. Some people prefer stirred. In that case, feel free to use a bowl or a large measuring cup with a spout.

This recipe makes two 12-ounce drinks or one large 24-ounce cocktail.

Sweetener Options

I sweeten this mojito with simple syrup, but you can absolutely use honey, agave, or even sugar if that’s what you have on hand. Simple syrup is my preference because it blends seamlessly into cold drinks. If using sugar, start with 1 to 2 teaspoons to the berries before you mash them. Once the rum has been added, taste for sweetness and add more sugar if needed.

How to make simple syrup

Combine equal parts sugar and water in a small saucepan, bring it to a boil just until the sugar dissolves, then turn off the heat and let it cool. I always keep a jar of simple syrup in the fridge—I use it for iced drinks and brush it onto cake layers when decorating to keep them extra moist. You can frequently see me do that on my videos.

Tips & Variations

• If your blackberries are very tart, add more sweetener and adjust after tasting.
• White rum keeps this light, but a lightly aged rum also works well.
• For a mocktail, skip the rum and add extra lime and seltzer.
• Add other berries to the mixture to make it a mixed berry drink.

FAQ

Can I make this ahead of time?
Yes, you can muddle and strain the blackberry, lime, and mint mixture a few hours ahead and keep it refrigerated. Add the rum, ice, and club soda right before serving so it stays fresh and bubbly.

Do I have to strain it?
Not at all. Leaving the berries in gives it a more casual, rustic feel — it’s purely preference.

Do I need a muddler?
A muddler helps, but the back of a wooden spoon works just fine. The key is pressing gently — not crushing — especially when it comes to the mint.

Can I use frozen blackberries?
Fresh is best for flavor and clarity, but frozen blackberries will work in a pinch. Let them thaw first and expect the drink to be slightly darker and softer in flavor.

This blackberry mojito is a staple for me when I want something easy, refreshing, and balanced. If you’re in the mood to try another version, my strawberry mojito and blood orange cocktail are both great options.
