Line a large baking sheet with parchment paper and grease the paper. In a small, heavy saucepan, combine the sugar and honey over medium-high heat. Stir the mixture until just melted; bring to a boil. Insert a candy thermometer and cook until the mixture is caramel colored and the temperature registers 300 degrees .
Remove the saucepan from the heat and stir in the butter until melted. Stir in the granola and pour the mixture on the prepared baking sheet, spreading into a 1/4-inch-thick rectangle. Let cool for 20 minutes.
Cut the brittle into 1/2-by-2-inch pieces. Let cool completely. Wrap each piece in a 3-by-4-inch piece of cellophane.
