Ingredients Needed for Toffee Chocolate Chip Bars
This is just a preview of ingredients and method, keep scrolling for full printable recipe.
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. Definitely try to find the ones that are just toffee, not chocolate-coated, but you can use whatever you have on hand. I’ve found the toffee-only bits to be harder and harder to find. I usually end up buying mine on either Amazon or at a restaurant supply store.





How to Make Toffee Chocolate Chip Bars
This is just an overview at a glance so you can get an idea of how this recipe works. Continue to end of post for the full printable recipe and instructions!
- In a large bowl, you’ll combine your dry ingredients and add cold butter to make a crumbly dough- I use a cheese grater so yes it looks like cheese! Then you’ll stir in an egg, add some chocolate chips, and press the mixture into a 9×13 pan.
- Bake for a few minutes and then pour a can of sweetened condensed milk on top and sprinkle on chopped toffee pieces.
- Cover this mixture with more cookie crumble dough and bake!
- When they’re all done you’ll sprinkle on a few more toffee pieces- and I like a sprinkle of flaky salt as well, to balance the sweetness. Let them cool completely before you cut into them.






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. Y
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!

Toffee Chocolate Chip Bars
Ingredients
- 2 ⅓ cups all-purpose flour lightly spooned into measuring cups and leveled with a knife
- ⅔ cup packed dark brown sugar
- ¾ cup cold salted butter
- 1 egg slightly beaten
- 1 12- ounce package semi-sweet chocolate chips
- 1 cup toasted coarsely chopped walnuts or pecans (optional; for real…I don’t use them)
- 1 14- ounce can sweetened condensed milk
- 1 ¾ cups toffee bits
Instructions
- Preheat oven to 350℉. Line a 9×13″ pan with parchment or spray with non-stick cooking spray.
- In a large bowl, combine the flour and brown sugar. Use a cheese grater to grate the butter and add it to the flour mixture. Combine the mixture with clean hands to form what resembles coarse crumbs, lightly breaking up butter pieces. Lightly beat the egg and pour it over the flour mixture and quickly combine it using a fork or clean hands.
- Reserve ½ cup of the chocolate chips and add the remaining 1½ cups chocolate chips to the dough mixture, along with nuts if using. Measure out 1 ½ cups of this dough mixture and set aside. Lightly press the remaining dough into the prepared pan and bake for 10 minutes.
- Remove pan from oven and pour the sweetened condensed milk over the hot crust, gently and lightly spreading it out without breaking up cookie dough below.
- Reserve ¼ cup of the toffee bits and set aside and pour the remaining bits over the sweetened condensed milk.
- Sprinkle the reserved 1½ cups dough mixture over the toffee bits and then sprinkle on the remaining ½ cup chocolate chips. Return to the oven and bake for 25-30 minutes or until golden brown. Mine usually take a little longer- like 30-35 minutes, but all ovens are different so keep an eye on them. When finished you should see them bubbling throughout, middle included, and the top should be starting to turn golden brown.
- Remove from oven and top with remaining toffee bits. Cool completely and then cut into bars.

Questions & Reviews
These look great! Would these be okay without toffee bits? I want to make them now but don’t have any toffee.
If you do, I’d replace them with something else (like more chocolate chips, peanut butter chips, butterscotch, white chocolate, etc.)
Who won the Bosch mixer? (obviously it wasn’t moi since I didn’t get an email, but I’m curious anyways). I don’t see it posted anywhere….
Wait a minute – back up. The dogs have their own room?!
Well, they’ve taken over my parents’ room. And bed. These people let my brother have one outdoor hunting dog while I was growing up, so I’m not quite sure who they are anymore…
Sometimes I’m forced to speak to them on the phone. Just ask Sara–she was there once.
Yum! Except I don’t usually have toffee bits on hand… Maybe we’ll have to change that!
Yum!
Love The Hunger Games! Those books never get old, do they? Suzanne Collins is brilliant. Also, I have to say I love the idea of grating the butter for this recipe. Although I’m not normally a sweets person, I will have to try this.
oooh, those look divine. i don’t care about this personally because i have a nut-allergic kid anyway, but you list nuts as an optional ingredient and then don’t mention them in the directions. (i am an editor by trade and apparently i can’t stop looking for stuff like that, NO MATTER HOW HARD I TRY.)
as always, i love your work! hope you get the laundry tamed soon (mine is still a wreck, and i’m not going to tell you how long ago spring break was around here. :))
I could eat about 50 of these. Ok, maybe 49…
So do you ever watch the Saturday Night Live segments with Stefon on Weekend Update? I had a dream last night that you and I were at a blogging event and they kept taking us to places like Stefon talks about and we were totally weirded out.
OK so I know you weren’t talking to me, but Stefon is my FAVORITE part of SNL!! I think he is so funny:)
Also-I’m making these today to take to a friend that just had a baby…. but they might not all make it to her house…. 🙂
Did you see the time Stefon totally broke character and started laughing? That was my favorite one. 🙂
I would definitely feel better coming home from vacation if I had a batch of these on the way!
I love anything with toffee! It’s too underused!
