Use a double broiler to melt together white chocolate chips, cream cheese, and heavy cream. You could also use a microwave-safe bowl at 30-second intervals but be careful as white chocolate can burn easily.
Once smooth, add in vanilla extract, 1 tablespoon cinnamon, and brown sugar. Stir well and remove from heat. Chill for 3 hours or until firm enough to roll into a ball.
Use a food processor (or put in plastic bag and crush) to pulse together graham cracker cookies until they're the consistency of sand. Stir in 2 tablespoons cinnamon and granulated white sugar.
