How to Make Rainbow Island Float: Vibrant Non-Alcoholic Layered Fruit Drink Recipe
Step 1: Prepare Ingredients
Start by chilling all your liquid ingredients and drinking glasses thoroughly to keep the layers distinct for longer. Let the rainbow sherbet soften for about 10 to 15 minutes so it scoops easily without melting too fast. Meanwhile, wash and prepare your fresh fruits by hulling, peeling, and slicing them into attractive bite-sized pieces. Arrange these on a platter—it makes garnishing a breeze and adds to the festive mood.
Step 2: Layer Syrups
Using chilled, clear glasses is key to showcasing the breathtaking layers of this recipe. Begin by gently pouring 1.5 to 2 tablespoons of grenadine syrup at the bottom for that brilliant red base. Hold the back of a spoon just above this layer as you slowly pour the orange syrup next—this technique helps keep each syrup separate. Continue layering the green apple or lime syrup, then the blue raspberry or blue curaçao syrup, and if you choose, finish the layers with the grape syrup. Pour each syrup slowly and carefully to ensure vibrant and distinct strata.
Step 3: Add Coconut Flavor & Soda
Now it’s time to drizzle in 1 to 2 ounces of non-alcoholic coconut syrup over the blue or purple layer for a tropical twist that rounds out all the fruity flavors. Then, slowly pour the chilled lemon-lime soda (or your preferred ginger ale or sparkling water) over the back of the spoon until the glass is about three-quarters full. The soda’s bubbles will add a lively fizz that makes every sip feel refreshing and fun.
Step 4: Add Sherbet & Garnish
Gently place a generous scoop of rainbow sherbet right in the center of the glass so it floats beautifully atop the layers. Surround the sherbet with the fresh sliced fruits—strawberries, kiwi, blueberries, and pineapple chunks—arranged artistically to create a feast for the eyes and palate. Top everything with a luscious swirl of chilled whipped cream, then generously sprinkle rainbow sprinkles for that extra pop of color and whimsy. Don’t forget to crown your float with a shiny maraschino cherry and a fresh mint sprig. For the perfect finishing touch, add a tropical drink umbrella and vibrant straw. Serve immediately to enjoy every vibrant, layered sensation.

Garnishes
Garnishing is where you can get truly creative and make the Rainbow Island Float your own. Fresh mint sprigs lend an aromatic brightness, while maraschino cherries perched on the whipped cream cap add a classic vintage vibe. Colorful rainbow sprinkles or candy pearls bring playful texture and festive flair that will delight both kids and adults alike.
Side Dishes
This float pairs wonderfully with light, summery snacks or tropical-inspired bites. Think fresh fruit skewers, coconut shrimp, or mini Hawaiian sliders to keep the island vibe rolling. Even simple coconut-flavored cookies or a bowl of tropical trail mix would complement the drink’s vibrant flavors beautifully.
Creative Ways to Present
Hosting a party? Serve your Rainbow Island Floats in clear glass mugs or fun tiki glasses to really show off those mesmerizing syrup layers. Add colorful straws and tiny paper umbrellas for that beach-bar aesthetic. For an extra festive touch, rim the glasses with colored sugar crystals or dip the rims in melted white chocolate and sprinkle with crushed freeze-dried fruit.
Make Ahead and Storage
Storing Leftovers
Because the Rainbow Island Float is a fresh, layered drink with sparkling soda and delicate sherbet, it’s best enjoyed immediately. If you have leftovers, keep the syrups and soda sealed and chilled in the fridge separately for up to three days. Fresh-cut fruit should also be stored refrigerated and used within two days for best flavor and texture.
Freezing
Freezing the syrups or fruits isn’t recommended because it can alter their flavor and texture. However, you can freeze the rainbow sherbet in its original container until ready to use again. Just allow it to soften slightly before scooping into fresh drinks.
Reheating
This recipe is designed to be served cold and fizzy, so reheating is not applicable. For a warm tropical treat, consider other fruit-based warm drinks or spiced teas instead.

- 1/4 cup blue raspberry syrup or non-alcoholic blue curaçao syrup
- 1/4 cup green apple or lime syrup
- 1/4 cup grape syrup or grape juice concentrate (optional)
- 1–2 oz non-alcoholic coconut syrup or extract
- 2–3 cans (12 oz each) chilled lemon-lime soda, ginger ale, or clear sparkling water
Dessert and Garnishes
- 1 pint rainbow sherbet (orange, raspberry, and lime flavors)
- 1 can (15 oz) chilled whipped cream
- 1 cup fresh strawberries, hulled and sliced or quartered
- 1 cup fresh blueberries or blackberries
- 1/2 cup fresh pineapple chunks, bite-sized
- 1 kiwi, peeled and sliced into half-moons
- 1 orange, thinly sliced and halved or quartered
- Maraschino cherries, with stems
- Fresh mint sprigs
- Rainbow sprinkles or colorful candy pearls
- Optional: Tropical drink umbrellas, long spoons, colorful straws
Instructions
- Prepare Ingredients: Thoroughly chill all liquid components including syrups and soda as well as the glasses. Slightly soften the rainbow sherbet by letting it sit out of the freezer for about 10 to 15 minutes to make scooping easier. Wash, hull, peel, and slice all fresh fruits as needed, then arrange them on a platter for easy and attractive garnishing.
- Layer Syrups: In each chilled, clear glass, carefully pour 1.5 to 2 tablespoons of grenadine syrup to establish the red base layer. Using the back of a spoon held just above the syrup layer, gently pour 1.5 to 2 tablespoons of orange syrup next. Repeat this layering technique with green apple or lime syrup, then blue raspberry or non-alcoholic blue curaçao syrup, and optionally add grape syrup. Pour each syrup slowly to keep the layers distinct and colorful.
- Add Coconut Flavor & Soda: Drizzle 1 to 2 ounces of non-alcoholic coconut syrup evenly over the blue/purple layer to add tropical flavor. Next, slowly pour the chilled lemon-lime soda, ginger ale, or sparkling water over the back of a spoon until the glass is about three-quarters full. This prevents the layers from mixing and maintains the visual appeal of the float.
- Add Sherbet & Garnish: Gently place a large scoop of rainbow sherbet into the center of each glass so it floats on top of the soda layers. Artfully arrange sliced strawberries, kiwi, blueberries, and pineapple chunks around the sherbet for color and texture contrast. Top each glass with a generous swirl of chilled whipped cream, then sprinkle liberally with rainbow sprinkles or colorful candy pearls. Finally, add a maraschino cherry and a fresh mint sprig as a finishing touch. Optionally, insert a tropical drink umbrella and a colorful straw. Serve immediately for best flavor and presentation.
