The best ever chocolate toffee oatmeal cookie bars! Rich and chewy, these easy cookie bars are like your favorite oatmeal chocolate cookies.



  • 2 1/2 cups flour
  • 1 cup rolled oats
  • 1 tsp cornstarch
  • 1 tsp baking soda
  • 1 tsp salt
  • 1 cup unsalted butter, at room temperature
  • 1 1/4 cups light brown sugar
  • 1 cup sugar
  • 1 large egg plus 2 egg yolks
  • 1 Tbsp vanilla extract
  • 1 1/4 cups semisweet chocolate chips
  • 1 1/4 cups toffee bits


  • 1/2 cup semisweet chocolate chips
  • Flaky salt


  1. Preheat oven to 350°F and line a 13 x 9-inch baking pan with parchment paper.
  2. Whisk together flour, oats, cornstarch, baking soda, and salt in a medium bowl. Beat butter and sugars in a large mixer bowl at medium speed until creamy. Beat in egg, egg yolks, and vanilla until combined. Reduce speed to low and gradually add flour mixture; beat just until incorporated. Fold in chocolate chips and toffee bits.
  3. Scrape dough into prepared pan. Use a piece of parchment paper coated with nonstick spray to press dough evenly across the bottom of the pan. Top with chocolate chips, pressing gently into the dough.
  4. Bake for 28 to 32 minutes, until golden and just set in the center. Remove from oven and sprinkle with flaky salt. Let bars cool completely on a wire rack before cutting into squares with a sharp knife.

  1. I absolutely cannot wait to make these! That extra sprinkling of salt on the end is giving me life. Love toffee everything!

      1. This recipe is such a huge hit in my family! I just can’t get over how amazing these are and so easy!!

  2. These are right up my alley! The toffee caught my attention, then the addition of oats sealed the deal! Can’t wait to make these gems.

  3. Absolutely delicious! I loved the gooey goodness of the combined chocolate chip and toffee bits. Thanks for the recipe!

  4. I made these today and they are delicious. This recipe is a keeper. I used 3 medium eggs and the bars turned out perfectly. I did not want to waste any whites, and it appears that the bars did not suffer from the substitution. Thank you for the recipe. I will make these again.

  5. Fantastic recipe! I had to sub golden raisins for the toffee chips (quarantine and cleaning out my pantry!) but it didn’t matter — these bars were super delicious. And easy enough to make with my toddler as my “helper.” 🙂 Thank you for sharing!

  6. I made these bars because I discovered I no longer have the patience for cookies 🍪!
    They are wonderful. This is the second time I have made them, and the next time I am going to use white chocolate chips instead of milk chocolate and add some coconut and craisins. Can’t wait! Thank you! I am going to share this with my daughter and her 5 year old — he loves his cookies.
