Make the simple syrup by heating equal parts sugar and water in either the microwave or on the stove. Heat until the sugar is dissolved, then transfer to a heat-safe container and allow it to cool.
Add the gin, lemon juice, and simple syrup to a cocktail shaker filled with ice. Cover the shaker, and shake for 20 seconds, or until the ingredients are cold.
Pour the mixture evenly into two champagne glasses. Then top with one ounce Champagne, and then top with BUBBL’R passion fruit wond’r (the amount varies based on the size of your glass, but in my glasses it was 3 ounces). Garnish with a lemon twist in each glass.
