Ingredients Needed

Cookie Crust
- All-purpose flour
- Dark brown sugar
- Salted butter
- Egg
- Semi-sweet chocolate chips
Filling
- Semi-sweet chocolate chips
- Walnuts or pecans – Chopped and toasted.
- Sweetened condensed milk
- Toffee bits – Such as Heath or Skor. I try to find the ones that are just toffee, not chocolate-coated, but you can use whatever you have on hand.
How to Make Toffee Chocolate Chip Bars
- In a large bowl, combine some flour and dark brown sugar. Combine the mixture and then grate in some cold or frozen butter. Combine with clean hands so it resembles coarse crumbs.
- Whisk an egg and drizzle it over the flour mixture. Combine it with clean hands until evenly distributed.
- Take a bag of chocolate chips and measure out 1/2 cup of them to set aside. Sprinkle the rest of the bag into the flour/sugar/butter mixture along with nuts, if using. Mix it with your hands and then reserve 1 1/2 cups of the crumbly dough mixture.
- Gently press the remaining dough mixture into a prepared 9×13″ pan and bake for 10 minutes. Remove the pan from the oven.
- Pour a can of sweetened condensed milk over the hot crust and spread it out evenly. Reserve 1/4 cup of a bag of toffee chips and sprinkle the rest of the bag over the sweetened condensed milk.
- Sprinkle the reserved dough over the toffee chips and then top with the reserved chocolate chips. Yes, I realize that I did not follow the directions and put things in the wrong order. It’s okay.
- Place the pan back into the oven for another 25-30 minutes or until golden brown.
- Allow the bars to cool completely (you can even pop the pan into the refrigerator–kind of like Reese’s Peanut Butter Cups and Popsicles, these bars are way better cold) and then cut into squares and serve.



Storing and Other Tips
- Store finished cookie bars in an airtight container at room temperature and enjoy within 3-4 days for best results. You can also store in the fridge if you prefer.
- Don’t be too hasty! Let the bars cool all the way before you cut into them for nice, clean edges.

Frequently Asked Questions
Sure! Bake the bars a day ahead and store at room temp or in the fridge until ready to serve.
Yep! I often leave them out and this recipe is still just as delicious. Be aware that most toffee bits contain almond, in case you’re wanting to avoid allergens. You could replace the toffee bits with caramel bits or butterscotch chips if needed.
Sure! White chocolate or butterscotch chips would be good here. You may want to balance them out with some dark or semi-sweet chips since this is a very sweet cookie bar. Shredded coconut would make a great add in as well!

Questions & Reviews
You’re evil. Those look WAY too good.
Oh my goodness, yes please! Why is toffee + chocolate such a perfect combination??
Oh wow, looks so Yummy. I can’t eat toffee (allergy) so will have to figure out something else that will work. Sadly all nuts are off limits. I have some mint chocolate chips in the freezer I could try. I’ve never grated butter before so this could be an interesting adventure!
Kristine, same at my house. What about salted caramel, you think?
Haven’t tried salted caramel before. Interesting. I’ll have to do some checking for something suitable.
Grating the butter…Seriously I think I just witnessed genius. That is brilliant.
just pulled my batch out of the oven and waiting for them to cool. Seriously, the smell in my kitchen is intoxicating and I’m having a hard time waiting to cut into them. My son loves anything with toffee, Heath Bars are his favorite, so I’m thinking I’ll be earning some extra points for dessert tonight!
Um serious light bulb moment when you said grate the butter!!! Why oh why have I never thought of that because I seriously despise cutting butter into things and almost always avoid recipes that call for that even though they are so good! Thank you for that life saver tip (or should I say life taking tip since now I will be looking at all the horribly unhealthy recipes lol)!!!
Okay, always looking for an easier way of doing anything, so using a food processor for cutting in the butter would be a lot faster.
Agreed, food processor is the fastest way to cut butter.
These look completely wonderful, but is anyone else out there ready for a sugar break? I OD’d on sugar last weekend and am looking for something delicious that won’t put me into a sugar coma.
Honestly, and I’m not trying to be snarky or anything, just laying my cards all out on the table: this was kind of like McDonald’s for dinner at the end of a busy day–I would have LOVED to have posted a dinner or salad recipe, but it just wasn’t in the cards. 🙂
I’m so glad this is what you chose!! They are wonderful!!
I was thinking these would be perfect for my egg-allergic son. But then in the recipe at the bottom, it says to include one egg….just curious – did you leave it out when you made yours?
I’m so sorry–that was a mistake on my part. I did use the egg and corrected the recipe.
These are my husbands favorite squares – thanks for reminding me it’s been awhile since I made them!!
These look divine! I’m going to make them with my kids this week (we are on Spring Break). 🙂 I had the pleasure of meeting you in Florida at Time Out For Women (I was tagging along with Tennisa, my BFF). Hope you are doing great! Thanks for all the yummy recipes!
