In a saucepan over medium heat, melt the brown sugar and butter. Cook for 2 minutes after melting until the mixture reaches a caramel color. Use a candy thermometer if desired, though not required.

While the caramel is cooking, lay down an even layer of pretzels in the baking tray.

Sprinkle white chocolate chips over the caramel-pretzel layer and place the tray in the oven for 4 minutes.
