Frozen Spiked Watermelon Slushie
This frozen spiked watermelon slushie is the perfect drink for hot summer days—refreshing, fruity, and naturally sweet with no added sugar. Made with frozen watermelon, vodka, prosecco, and fresh lime juice, it’s an easy-to-make cocktail that blends up in minutes and satisfies any sweet frozen drink craving.
Ingredients
- 2 cups frozen watermelon cubes from ripe, seedless watermelon
- 1½ oz vodka
- 2 oz prosecco or sparkling wine
- Juice of ½ lime or about ½ tablespoon fresh lime juice
- Optional: 1 teaspoon simple syrup depending on sweetness of melon
- Lime wedge, fresh mint, or small watermelon wedge for garnish
Instructions
- Cut fresh, seedless watermelon into chunks and freeze in a single layer on a parchment-lined baking sheet until solid (about 4 hours).
- Add frozen watermelon cubes, vodka, prosecco, lime juice, and simple syrup (if using) to a high-powered blender or food processor.
- Blend until smooth and slushy. Add a splash more prosecco or cold water if the mixture is too thick, more frozen watermelon if too thin.
- Pour into a chilled glass.
- Garnish with a lime wedge, sprig of mint, or a small watermelon wedge, if desired.
- Serve immediately and enjoy!
Notes
Tips:
- Chill your glasses in the freezer for 10–15 minutes before serving. Your slushie will stay icy longer and look extra pretty with in the frosty glass.
- For a mocktail version, leave out the alcohol and use sparkling water in place of prosecco.
- Make it ahead: Blend the drink and freeze in an airtight container. Stir or re-blend before serving if it separates.
- If your watermelon is very sweet, you may not need any simple syrup at all—I did not.
