Turn the beloved childhood drink into a creamy summer treat that brings back sweet memories with every sip. This float combines the classic cherry-citrus flavors of a Shirley Temple with smooth vanilla ice cream, creating a refreshing dessert drink that's both nostalgic and new. After experimenting with different ratios, I've found the perfect balance that makes this float taste like a summer dream.
Last weekend, I served these at a retro-themed pool party, and watching adults' faces light up with childhood memories was priceless. Even the kids, who'd never had a traditional Shirley Temple, fell in love with this creamy version.
Essential Ingredients
- Lemon-Lime Soda: Use chilled 7UP or Sprite for the best fizz. Its citrus notes complement the grenadine
- Ginger Ale: Adds a subtle warmth and extra dimension of flavor
- Grenadine Syrup: Creates that signature cherry sweetness and beautiful pink color
- Premium Vanilla Ice Cream: Choose a quality brand for the creamiest results
- Maraschino Cherries: Not just for garnish, they complete the classic Shirley Temple experience
Detailed Cooking Instructions
- Glass Preparation:
- Start with a tall glass chilled in the freezer for about 10 minutes. This helps maintain the perfect temperature and keeps your ice cream from melting too quickly. The size of your glass will determine how many scoops of ice cream you'll need.
- Ice Cream Base:
- Add 2-3 generous scoops of vanilla ice cream to your chilled glass. Don't pack them too tightly - you want spaces between the scoops for the liquid to flow through, creating that perfect float consistency.
- Liquid Addition:
- Pour the grenadine first, letting it cascade over the ice cream. Follow with equal parts lemon-lime soda and ginger ale, pouring slowly down the side of the glass to maintain carbonation. The mixture will create a beautiful swirled effect as it combines.
- Final Assembly:
- Top with a maraschino cherry and a fresh lime slice. Add a colorful straw both for function and fun - the wider the straw, the better for managing both liquid and ice cream.

What started as a way to make children feel special at fancy establishments has evolved into this elevated dessert drink. My grandmother used to make me Shirley Temples when I helped in her kitchen, and this float version brings those memories flooding back.
Creative Variations
The basic recipe is just the beginning. For adults, create a "Dirty Shirley" float by adding a splash of vodka and amaretto. Sometimes I'll use cherry vanilla ice cream instead of plain vanilla, or add a splash of fresh lime juice for extra zing. Each variation maintains the nostalgic charm while offering something new.
Temperature Matters
The success of this float depends on temperature control. Using chilled glasses and sodas creates the perfect environment for the ice cream, preventing it from melting too quickly. The goal is to maintain that perfect creamy-fizzy balance from first sip to last.
Serving Suggestions
Present these floats with both a straw and a long spoon - they're meant to be both sipped and spooned. For parties, set up a float bar with different ice cream flavors and garnish options. Let guests build their own combinations while maintaining the classic Shirley Temple base.

Final Thoughts
This Shirley Temple Ice Cream Float represents the perfect marriage of nostalgia and innovation. Each sip combines the familiar cherry-citrus flavor we loved as kids with the creamy indulgence of a dessert. Whether you're recreating childhood memories or introducing the next generation to this classic flavor combination, this float proves that some things just get better with time. It's become more than just a recipe in my collection - it's a way to share sweet memories while creating new ones.
