Pour 4 cups of raspberry lemonade into 2 standard-size ice cube trays.
Freeze the lemonade cubes until solid, about 4 hours or overnight.
Place the remaining 2 cups of raspberry lemonade in the refrigerator.
Add 1 tray of frozen lemonade cubes to a blender.
Add 1 cup of the refrigerated lemonade, ½ cup lemon-lime soft drink, ½ cup raspberry vodka, and ¼ cup fresh lemon juice.
Blend until smooth.
Pour the mixture into 4 large glasses.
Garnish each glass with fresh raspberries and mint leaves.
Repeat the same steps with the remaining ingredients to make 4 more drinks.
Notes
Tips and Tricks
Freeze the lemonade ahead of time - The lemonade cubes need to be solid before blending. Overnight works well if you want to make the drinks the next day.Use chilled liquids - Cold lemonade, soda, vodka, and lemon juice help the cooler stay thick and frozen longer.Blend in batches - This recipe is made in two batches so the blender can handle the frozen cubes without overfilling.Serve right away - Frozen drinks melt as they sit, so pour them into glasses as soon as they are blended.Adjust the texture - For a thicker drink, use a little less refrigerated lemonade. For a thinner drink, add a small splash more.
