Full of buttery toffee flavor, Pecan Chocolate Toffee Bars are simply heavenly. A cookie base reminiscent of shortbread is prepared with brown sugar (providing that luscious toffee flavor) and, once baked, is topped with melted chocolate and chopped toasted pecans. Super easy to prepare, these Toffee Bars are true crowd pleasers!

  • Prep Time: 10 mins
  • Cook Time: 20 mins
  • Total Time: 30 minutes
  • Yield: Makes 3 to 4 dozen 1x
  • Diet: Vegetarian


  • 1 cup butter, softened
  • 1 cup firmly packed light brown sugar
  • 1 egg yolk
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • 2 cups all-purpose flour
  • 8 ounces milk chocolate (such as Hershey brand), broken into pieces
  • 1/2 cup chopped roasted pecans


  1. Preheat oven to 350 degrees.
  2. Lightly butter a 10 by 15-inch rimmed baking sheet (see Note below).
  3. In a large mixing bowl, using an electric mixer with the paddle attachment, beat the butter and sugar until well mixed and light in color.
  4. With the mixer running, add the egg yolk and vanilla; beat until blended.
  5. Add the salt and flour and beat just until blended.
  6. Spread in prepared pan and top with a piece of waxed paper. Push down on the paper to spread the dough evenly in the pan. Remove the paper and bake for 20 minutes.
  7. While the cooking are baking, in a small glass bowl melt chocolate in a microwave oven (do not overheat or it can turn white).
  8. Remove cookie base from oven and immediately spread chocolate over top. Sprinkle with chopped pecans, pressing down lightly to make sure they adhere to the chocolate.
  9. Let cool until the chocolate hardens (I put it in the refrigerator for around 1 hour).
  10. Cut into bars and serve.


Baking dish: You can also make these cookies in a 9 by 13-inch baking dish; increase cook time by 5 to 10 minutes.

How to store: Store cookies in an airtight container in the refrigerator. They’ll last for around 4 to 5 days (but they’re always eaten up before then in my house!). Bring to room temperature before serving. They can also be frozen in an airtight container, for up to 1 month.
