Transfer frosted lemonade to 2 glasses and garnish with lemon slices.
Notes
Use cold ingredients: Keep the lemonade and ice cream cold until you're ready to blend for the thickest, frostiest consistency.
Customize the texture: For a thicker drink, blend briefly. For a thinner, smoother consistency, blend a bit longer or add a few ice cubes if it gets too thick.
Chill your glasses: Pop your glasses in the freezer before serving to help keep your frosted lemonade colder for longer.
Blend thoroughly: Make sure to blend until completely smooth for the best texture—no icy chunks or uneven swirls.
Add a lemony boost: Want a stronger citrus flavor? Add a splash of fresh lemon juice or a pinch of lemon zest—but avoid zesting into the white part of the rind, as it can taste bitter.
Serve with style: Dress it up with a fun straw or serve in a milkshake glass for extra charm and presentation.
