Blue raspberry lemonade is my go-to on warm days when I want something eye-catching and super zesty. Anytime I'm hanging out in the backyard or settling in for a movie with the family, I toss this together for an instant mood boost. All you need are a handful of basics and you’re set with a bold blue sipper that feels perfect for summer.
I first made this drink at my kid’s birthday bash and it was a crowd favorite. Kids couldn’t get enough of the color, and adults kept coming back for more. Now, it’s everyone’s first choice as soon as the temps rise.
Lively Ingredients
- Lemon slices: these add fresh scent and look cheery on top
- Ice cubes: loads of ice makes each glass super cold
- Blue raspberry syrup: go for quality since the flavor and awesome blue color come from here
- Fresh lemon juice: squeeze your own lemons for sharp tang, and strain so everything stays smooth
- Granulated sugar: use regular sugar and add more or less for the taste you like
- Cold water: for best flavor, pick filtered water if your tap water’s not great
Chunky, juicy lemons have way more juice and pack in more punch. Don’t cheap out on the syrup either—this is where all the bold flavor really shines through.
Easy Step-by-Step Guide
- Chill and garnish:
- Pack your glasses with lots of ice, pour in the blue lemonade, then top with a bright lemon slice for extra zest.
- Balance the flavors:
- Before you serve, taste it! Add more lemon juice if you want it punchier, or a sprinkling of sugar if you lean sweet—give it a good stir.
- Mix the lemonade:
- Grab a big pitcher, add your cooled simple syrup, three cups cold water, and blue raspberry syrup. Stir until the color’s even and striking.
- Prepare the syrup:
- Stir sugar into one cup of cold water in a pot on medium heat, letting it melt all the way for a clear syrup. Let it cool completely so it won’t water down your drink with melted ice.

The blue raspberry syrup does all the heavy lifting here—it’s what makes the drink feel special and brings all those fun throwback vibes. My crew always cracks up over the blue mouths and starts swapping stories whenever that big blue pitcher shows up.
Keeping It Fresh
If you have extra, stash it in the fridge and it’ll stay fresh for two days. Just stir before you pour because the syrup can settle. Want it ready ahead? Chill the lemon and syrup blend, and only add ice when you’re about to serve so it won’t get watery.
Swaps and Alternatives
Bottled lemon juice is totally fine if you’re rushing around, but the fresh stuff really does pop. To cut back on sugar, try a sweetener that’s meant for drinks—check that it dissolves easily. Out of blue raspberry syrup? Raspberry or blueberry syrup works, though the color might change up.

Ideas for Serving
Pour into see-through pitchers or tall glasses so the blue color really shows off. Add extra lemon slices or toss in mint for a fresh look. For the grown-ups, splash in some gin or vodka and you’ve got a fun twist.
Flavorful Origins
Blue raspberry brings back childhood for tons of folks in North America, especially memories of blue candies or snow cones. Mixing it into lemonade creates that classic taste—just a little grown up. You’ll be making it over and over again.
