Pop popcorn according to package directions. Open bag carefully and pour into large bowl; discard unpopped kernels. Add chow mein noodles to bowl. In a small microwave-safe bowl, melt baking chips, peanut butter and white chocolate, uncovered, on HIGH (100% power) for 2 minutes; stir well. Pour over popcorn mixture; stir until evenly coated. Drop mixture by large rounded tablespoonfuls onto wax paper-lined cookie sheets. Refrigerate until firm, 1 to 1-1/2 hours. Store in tightly covered container.
