Our town library hosts a monthly “family movie night” that everyone looks forward to. Parents bring snacks, kids spread blankets across the floor, and the snack table becomes a little competition of homemade treats. One month, I watched a group of kids stare at the dessert table trying to decide between brownies and cookies. A dad nearby joked that someone should invent a dessert that solved the debate once and for all.

⁠

That comment stuck with me during the drive home. The next day at work, a coworker mentioned her daughter wanted brownies for her birthday while her son insisted on chocolate chip cookies. Hearing both stories in the same week made the idea feel too perfect to ignore. By Friday evening, my kitchen counter was covered in butter, chocolate, and mixing bowls.

When the finished cake appeared at the movie night table, kids gathered instantly and adults asked questions before the first slice was even served. The tray came home empty, and several parents asked for the recipe the next morning.
