Started by the four young women with the similar interest for sweet treats, Whoops! is the soon-to-be-launched whoopie pie online store. It was found by Karina Maharani, Kimberly Lie, Nania Marli, and Winny Kartika on September 19th 2018 and will officially be opened on the beginning of June 2019. With the vision to bring joy to customers through desserts, these four sweets-enthusiasts believe that “Happiness is a Virus”. It makes the rule that every warm, sweet, and soft desserts shall be baked with joy and happiness.​
