Gather your ingredients: freshly squeezed lemon juice, cold water, and creamy vanilla ice cream. Make sure your water is ice-cold to ensure the best texture. Have a blender ready and your glasses pre-chilled for that perfect presentation.

In the blender, combine the freshly squeezed lemon juice, vanilla ice cream, and a cup of the ice-cold water. Blend on medium-high for about 30 seconds or until the mixture is smooth and creamy.

If the mixture is too thick for your liking, add a splash more cold water and blend again for another 10 seconds.

Pour your frosted lemonade into the pre-chilled glasses. Garnish with a slice of lemon or a sprig of mint if you're feeling fancy.
