Preheat oven to 400°. Line a large rimmed baking sheet with foil; spray foil with cooking spray.
Arrange saltines in an even layer on prepared pan.
In a medium saucepan, bring butter and brown sugar to a boil over medium-high heat; cook, stirring constantly, for 2 minutes. Remove from heat, and stir in condensed milk. Pour mixture onto crackers.
Bake for 10 minutes. Sprinkle with white chocolate; let stand until softened, about 2 minutes. Spread softened chocolate onto cracker layer. Sprinkle with pecans, cherries, and cranberries. Let cool completely on a wire rack. Break into cracker-size pieces. Store in an airtight container for up to 3 days.
