1 c. Packed Brown Sugar
2/3 c. Milk
2 tbsp. Corn Syrup
1/2 tsp. Salt
2 tbsp. butter
1 tsp. Vanilla

Use a butter loaf pan. 9 x 9 x 3 inches. Heat sugar, milk, brown sugar, corn syrup and salt in a 3 quart pan on medium heat, stirring constantly until sugars are dissolved. Cook stirring occasionally to 234°F on candy thermometer. Remove from heat and add butter. Cool without stirring to 120°F (bottom of pan will be lukewarm). Add vanilla, beat continually with wooden spoon until candy is thick and no longer glossy, 5-10 minutes. Mixture will hold its shape when dropped from spoon. Quickly stir into loaf pan.
