In a small saucepan, combine 1 cup of water and 1 cup of sugar. Heat over medium heat, stirring gently until the sugar is fully dissolved, which should take about 3-5 minutes. Remove from heat and let the mixture cool.

In a large mixing bowl, pour in 1 cup of freshly squeezed lemon juice. Gradually add the cooled sugar mixture to the lemon juice, stirring continuously to combine.

Blend in 1 cup of pureed strawberries into the mixing bowl, stirring thoroughly until well incorporated.

Pour the strawberry-lemon mixture into a large serving pitcher and gently add 2 cups of sparkling water, stirring carefully to maintain the fizz.

In a separate bowl, whip 1 cup of heavy cream with 1 teaspoon of vanilla extract until soft peaks form, about 3-5 minutes.

Carefully fold a portion of the whipped cream into the pink lemonade mixture using a spatula.

Pour the creamy Pink Lemonade into glasses, topping with a dollop of the remaining whipped cream, and garnish with lemon slices and fresh mint leaves.
