We partnered with Lactaid to celebrate the age-old combination of cookies and milk, with a whimsical twist. From Halloween through Christmas we delighted Pinterest planners with stop-motion videos featuring scenes made entirely of cookies and frosting. To really grab their attention, we hacked the Pinterest platform with vertical videos. We created an optical illusion of two stacked scenes—a cookie world on top and an enticing glass of Lactaid Milk below. The cookies jumped down into the glass of milk, abandoning their original pin and proving that with Lactaid, no one (cookies included) needs to go without irresistible, real milk.
