How to Make Rainbow Island Float
Step 1: Chill Your Glass
Place a tall glass or float glass in the freezer for 10–15 minutes. This will give your drink a frosty effect that enhances its refreshing quality.
Step 2: Layer the Base
Add 2–3 scoops of rainbow sherbet directly into the chilled glass. This forms the colorful base of your float.
Step 3: Add the Coconut
Slowly pour ½ cup of coconut milk or coconut cream over the sherbet. Allow it to swirl around the scoops for an enticing visual effect.
Step 4: Spike or Skip
If you’re preparing a cocktail version, drizzle in 1 oz of Malibu rum at this point. For a kid-friendly mocktail version, simply skip this step.
Step 5: Fizz It Up
Gently pour ½ cup of lemon-lime soda over the top. Watch as it foams and bubbles, creating that magical floating effect.
Step 6: Top It Off
Add a generous swirl of whipped cream on top. This adds an extra layer of creaminess that complements the flavors beautifully.
Step 7: Garnish
Decorate your Rainbow Island Float with a mini paper umbrella or a colorful rainbow straw for added tropical flair.

Common Mistakes to Avoid
When preparing your Rainbow Island Float, it’s easy to make a few common errors. Avoiding these mistakes will ensure your float is as delightful as it should be.
- Using warm glasses: Always chill your glass before serving. A warm glass can melt the sherbet quickly, ruining the layered effect and making the drink less enjoyable.
- Pouring too quickly: When adding coconut milk or soda, pour slowly. This helps maintain the beautiful layers and prevents them from mixing too much, keeping that rainbow effect intact.
- Skipping the garnish: A mini paper umbrella or colorful straw adds fun to your drink. Don’t skip this step; it enhances the presentation and makes it feel special.
- Not adjusting sweetness: Depending on your taste, you might want to adjust the sweetness. If you find it too sweet, opt for a light soda or use less sherbet.
- Ignoring texture: For a creamier float, use coconut cream instead of coconut milk. This simple switch can elevate the overall mouthfeel of your Rainbow Island Float.
Refrigerator Storage
- Store any leftover Rainbow Island Float in an airtight container in the fridge for up to 2 days.
- Keep in mind that it may lose its fizzy element, so it’s best enjoyed fresh.
Freezing Rainbow Island Float
- If you have leftovers, freeze them in an airtight container for up to 1 month.
- When ready to enjoy again, allow it to thaw slightly before serving, but be aware that texture may change after freezing.
Reheating Rainbow Island Float
- Oven: Not recommended as this drink should be served cold.
