Hershey's Bar Toffee Squares

A friend gave me this recipe several years ago and it's become a real favorite!

• Ready In: 25 mins
• Yields: 24 squares

Ingredients

• 1  cup butter, softened (not margarine)
• 1  cup  packed brown sugar
• 1  egg yolk
• 1  teaspoon vanilla
• 2  cups flour
• 1⁄4 teaspoon salt
• 4  Hershey Bars, separated into squares
• 1⁄2 cup  finely chopped walnuts

Directions

1. Preheat oven to 350 degrees.
2. Beat butter, sugar, egg yolk and vanilla until creamy.
3. Add flour and salt; mix well.
4. Pat dough into a 10x13" rectangle on greased cookie sheet.
5. Bake for about 20 minutes- until dough is set and lightly browned.
6. Remove from oven and immediately top with the Hershey bar squares.
7. When squares have softened (and it doesn't take long!) spread evenly and top with the finely chopped walnuts.
8. Cut into bars while warm, as these are difficult to cut when cooled.
