This breezy limoncello float is my favorite instant dessert for summer nights on the patio when friends drop by and you want something dazzling but effortless. Creamy ice cream swirls with citrusy liqueur and bubbles, making each spoonful taste like a vacation on the Amalfi coast. Whether you love Italian flavors or just enjoy easy treats with serious wow factor, you will make this again and again.
The first time I served this, my friend closed her eyes at the first sip and said it tasted like adult lemonade stand. This is now my favorite way to celebrate Fridays in July when the golden hour light hits just right.
Ingredients
- Vanilla or lemon ice cream: A creamy and rich base that adds a luxurious mouthfeel. Look for brands that use real vanilla beans or lemon zest for extra flavor.
- Limoncello: Bright Italian lemon liqueur for zing and aroma. Choose a bottle that is clear and vibrant in color for the freshest citrus punch.
- Prosecco: Dry sparkling wine adds lively bubbles and balances the sweetness. If possible, select a bottle labeled brut for a crisp finish.
- Lemon slices: Freshly cut to add aroma and an elegant garnish. Choose firm lemons with glossy skin for peak flavor.
Step-by-Step Instructions
- Prepare the Glasses:
- Choose tall glasses or wine glasses without residue and set them on your serving tray. Chilled glassware keeps your float colder and prevents melting.
- Scoop the Ice Cream:
- Portion a large scoop of vanilla or lemon ice cream into each glass. Try not to press it down so the prosecco bubbles have room to rise around it.
- Pour the Limoncello:
- Carefully drizzle measured limoncello over the ice cream letting it pool and soak slightly. This infuses every bite with a fragrant citrus kick.
- Add Prosecco:
- Slowly pour prosecco into the glass til it is three quarters full letting the bubbles fizz and combine with the ice cream. The ice cream will float and froth just right.
- Garnish and Serve:
- Place a thin lemon slice on top of each float and offer a small spoon alongside for scooping. Serve immediately while everything is icy and sparkling.

Limoncello started as a family favorite for my summer birthdays. Watching everyone take their first frothy spoonful was like sending little rockets of joy around the table. My personal favorite part is the moment when the ice cream starts melting into the prosecco because that is when all the flavors fuse.
Storage Tips
Floats are always best assembled just before serving so the ice cream stays cold and the bubbles lively. If you want to prep ahead just keep your glasses in the freezer, scoop ice cream onto a lined sheet tray and store covered for one hour. This way everything is ultra chilled when ready to pour.
Ingredient Substitutions
For non dairy guests, try a good quality vegan vanilla or lemon gelato. Sorbet works beautifully for a more tart finish. If you cannot find limoncello, you can use another citrus liqueur or even a splash of fresh lemon juice with a little sugar for brightness.
Serving Suggestions
Try rimming the glass with a tiny bit of raw sugar and lemon zest for sparkle. Serve with biscotti or amaretti cookies. It fits beautifully at the end of an Italian meal or as a spotlight opener for a small party.
Cultural Context
Limoncello hails from the southern coast of Italy where lemons are legendary and every family seems to have their own recipe. Prosecco is the norths answer to sparkling wine. Italians savor both for celebrations and casual get togethers and this float is a playful tribute to their joyful approach to flavor and fun.

This dessert is the easiest way to bring vacation vibes right to your patio. In just minutes, you’ll have a little Italian sunshine in a glass.
