These Toffee-Chocolate Chip Cookie Bars are a variation on the traditional Toll House Chocolate Chip Cookies my mom made when I was growing up. They are chewy, chocolatey and caramel-y deliciousness!

The Family Cookie Jar

Growing up, the cookie jar in our kitchen was always, and I mean always, full of delicious cookies. Most often, it was chocolate chip cookies. And, my mom followed the popular chocolate chip cookie recipe at the time – from the Toll House Inn in Massachusetts. Even today, eating chocolate chip cookies brings back visions of our family cookie jar – which I now have in my own kitchen! It was included in the cookie photo in my first cookbook, A Well-Seasoned Kitchen®:

How to make Chocolate Chip Bar Cookies with Toffee

Recently, I started to play around with the traditional Toll House Chocolate Chip Cookie recipe that I found in mom’s recipe box. First, I switched out half of the chocolate chips for English toffee-flavored chips. Mom also made her own amazing Chocolate Almond Toffee – so that’s another flavor I am partial to – and I was thrilled to find Heath Milk Chocolate English Toffee Bits at the grocery store one day. If you can’t find them at your store, no worries – I provide substitutions in the recipe’s Notes section.

Next, I simplified the process by making bar cookies instead of drop cookies. And, I created my own high altitude adjustments, based in large part on recommendations from my favorite high altitude baking cookbook, “Pie in the Sky” by Susan Purdy. (High altitude adjustments are included in my recipe’s Notes section.)

The resulting cookies are now Robert’s favorite! They are chewy, chocolatey, caramel-y tasting – and oh, so delicious. When eating these delectable cookies, I can still see my brother Jim trying to very quietly take the lid off the cookie jar, to grab a cookie (or two) before mom caught him doing so . . .

Chocolate Chip Cookie Bars with Toffee

  • Author: (By Lee Clayton Roper; adapted from the original Toll House Chocolate Chip Cookie recipe found in my mom's recipe box)
  • Yield: Around 5 dozen 1x
  • Category: cookies, desserts, easy


These Toffee-Chocolate Chip Cookie Bars are a variation on the traditional Toll House Chocolate Chip Cookies my mom made when I was growing up. They are chewy, chocolatey and caramel-y deliciousness! High altitude adjustments included in Notes section.


  • 2 1/4 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon table salt
  • 1 cup unsalted butter (2 sticks), softened
  • 3/4 cup granulated sugar
  • 3/4 cup packed brown sugar
  • 1 teaspoon vanilla extract
  • 2 large eggs
  • 1 cup toffee (Heath Bar) chips – See Note
  • 1 cup semisweet chocolate chips
  • 1 cup chopped pecans, toasted


  1. Preheat oven to 350 degrees. Line a half-sheet pan (13 by 18-inch) with parchment paper.
  2. In a medium mixing bowl, whisk together the flour, baking soda and salt. Set aside.
  3. Using an electric mixer with the paddle attachment, beat butter until creamy. Beat in granulated sugar and brown sugar until blended. Beat in vanilla extract. Add eggs, one at a time, beating well after each addition. Gradually beat in flour mixture. Stir in toffee chips, chocolate chips and nuts. Cover and refrigerate dough for 30 minutes.
  4. Spread dough in prepared pan by placing small clumps around the pan. 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 18 to 20 minutes, or until light golden brown.
  5. Cool completely in pan on a wire rack. Cut into bars and serve.


Heath Bar chips: if you can’t find these in your grocery store, buy a few Heath candy bars (Almond Roca candy would also work), put in a zip top baggie, and smash into bits!

High altitude: Increase flour by 1/4 cup. Increase vanilla by 1/2 teaspoon. Increase oven temperature to 375 degrees and reduce cook time to 15 to 17 minutes.

Make ahead: Dough can be prepared, covered and refrigerated for up to 3 days. Let sit at room temperature just until pliable enough to spread in the pan.
