6 ounces (4 cups) pretzel sticks
1 1/4 cups firmly packed brown sugar
1 (12-ounce) package real semi-sweet chocolate chips
2 ounces white chocolate baking bar, curled
Heat oven to 400ºF. Line 15x10x1-inch baking pan with aluminum foil; butter foil.
Place pretzels in single layer on pan.
Combine brown sugar and butter in medium saucepan. Cook over medium heat until mixture comes to a full boil. Continue cooking 2 minutes. Pour mixture over pretzels.
Bake 10 minutes. (Mixture may look foamy.) Remove from oven; sprinkle evenly with chocolate chips. Return to oven 1 minute to soften chocolate chips. Remove from oven. Gently spread chocolate over pretzels; cool 30 minutes. Sprinkle with white chocolate curls; cool completely.
Break or cut into pieces.
To make white chocolate curls, shave sides of white chocolate baking bar using vegetable peeler, letting curls or shavings fall onto waxed paper or paper towel.
