These Heath Bar Crunch Cookie Bars are a STSL favorite! Buttery and gooey with sweet and crunch toffee chunks, they basically melt in your mouth and just put a smile on your face.
Ever since I tried the Heath Bar Crunch cookie from The Fresh Market last week, I’ve pretty much been obsessed. And that’s probably putting it lightly. Ask me if I got one this weekend on our stop back to get more coffee and pasta…I’ll proudly tell you ABSOLUTELY; and I wasn’t even ashamed to ask the girl in the bakery if there were any extra when I noticed the case was empty. I guess I’m a die hard.
On Sunday, I offered to provide some sweets for our Football party…since they’re already kind of expected from me as it is. I wanted something that would be quick and easy to be able to “grab ‘n eat” while watching the games. So I automatically thought: COOKIES.
However, some days I just really don’t feel like standing in front of the oven, plopping spoonfuls of dough onto cookie trays. Anyone else with me? So that’s where the cookie BARS came into play.
You can never go wrong with a classic chocolate chip, am I right? BUT then again, why not jazz it up a bit? Since I already had Heath bars on the brain, I decided to attempt to my own version of them. Because, well, I’m obsessed.
The Heath bars in these cookies are absolutely phenomenal. And please, don’t go buying actual Heath bars and attempt to crush them up yourself…way too much work. Just buy the bag of the Toffee Heath Bar Bits at the grocery store, and you’re good to go.
Oh, and if you’re a chocolate fan like me, feel free to add in extra chocolate chips…life’s just always a little better with more chocolate.
One of the keys to the moist, dough-like consistency of these bars is to undercook them. After 10 minutes, when I pulled mine out of the oven, they definitely did not look done. But TRUST ME, leave ‘em alone until they’re completely cooled, and you won’t regret it. Either will your friends.

Heath Bar Crunch Cookie Bars
Ingredients
- 2-1/4 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1 cup 2 sticks unsalted butter, room temperature
- 1/2 cup granulated sugar
- 1 cup packed light-brown sugar
- 1 teaspoon salt
- 2 teaspoons pure vanilla extract
- 2 large eggs
- 1-1/2 cups Toffee Heath Bar Bits
- 1/2 cup semi-sweet chocolate chips
Instructions
- Preheat oven to 350 degrees. In a small bowl, whisk together the flour and baking soda; set aside.
- In the bowl of an electric mixer, combine the butter with both sugars; beat on medium speed until light and fluffy. Reduce speed to low; add the salt, vanilla, and eggs. Beat until well mixed, about 1 minute.
- Add flour mixture; mix until just combined
- Stir in the chocolate chips.
- Spray a 10x15x1 baking pan with non-stick cooking spray (a 9×13 pan will work as well). Spread cookie dough evenly in the pan.
- Bake cookies 10-12 minutes. They will still be soft in the center. Remove from oven, and let pan cool completely on a wire rack. Cut into desired amount of bars. ENJOY!
And just for fun, a little throwback to the original photos from when this recipe was first published in 2010.

You had me at Heath Bar. :)
These look awesome! I love the toffee bits, I used them in a cookie recipe contest a couple months ago.
Me + Heath Bars = Love. These look fantastic!
I love cookie bars, even more than I love cookies to be honest…these look so good. Your blog makes me want to do nothing but bake all day, and I love it.
Hahaha, excellent! :)
I feel like Homer Simpson does with donuts..
Heath bar… *drooooooooool*
So delicious. Heath bars remind me of my grandpa, so they have sentimental meaning with me too. Thanks for sharing!
HOLY YUM!! I am totally giving those a try. Anything with toffee and chocolate you can count me in!
I love underbaking cookies and brownies and the like. It makes everything so much softer and gooier. Though that makes them too easy to eat. Sometimes I’ll put cookies in the freezer because it will take me longer to eat each one, then I eat fewer. :)
Heath bar? Heck yes! They’ve been my fav since day one. Love the sounds of this recipe!
Just have to say I’m a bit obsessed with the Fresh Market Heath cookies too. :) I’m desperately searching for a similiar recipe!
Just don’t use LIGHT stick butter (which I use in most recipes) or you will end up with heath bar crunch cake :-)
How long did you cook this using a 9×13 pan? I made this recipe using a 9×13 and cooked it 35 minutes and it was almost raw on the bottom. Wonder what I did wrong?
Hmmm, I’m not sure? I did mine in a 15×10, so that probably made a significant difference. Hopefully they turned out okay after you let them cook a little longer?? :)
You’re recipe says 9×13. Did you adapt the recipe?
Yes, I did wind up changing the recipe! Good catch, Susan! If you do 9×13 you’ll want to cook for closer to 35-40 minutes
So is this recipe for the 15×10 pan then? That is what I’m looking for. Saves me from having to adjust 😁
Been eating heath bar cookies for 25 years. Nothing like it.
Hey, where do you say to add the toffee bar bits??
So the recipe says to cook a 9×13 for 20-22 minutes and then in the comments you say 35-40. Could you please clarify?
Sorry Marie, just updated the recipe! If cooking in a 9×13, try baking for about 35 minutes. If you’re using a 15×10 pan, reduce the cooking time to be 20-22 minutes!
Thanks so much!! Looking forward to trying it today!!
When using the 10×15 jelly roll pan and wanting that gooey undercook affect do you cook for just 10-12 minutes then take out of oven? I see actual cook time is 20-22 minutes on jelly roll pan size but also see where you personally removed the bars after 10 minutes and note they were gooey and delicious… sorry just trying make sure I get this right. Also could only find Heath bits o brackle toffee bits (same as original but no chocolate on them just toffee bits)will these be okay to use? Thank you!
hey friends, in the recipe you forgot to put when you put the heath in :)
Updated, thanks Noah :)
Can you make these in mini mufins, if so how long to cook
Hey Melissa, I’m sure you could! I’ve never tried it though so I’m really not sure what to recommend for time. I’d say just eyeball them and check every 5 minutes or so!
Can I adnutsto the bars?
Can you add walnuts?
Sure!

This was delicious! I’m a terrible cook and it turned out just fine, nice and easy.
These are delicious! I followed the recipe as is and baked for 11 minutes. They look perfect and taste wonderful!
I followed your recipe exactly and it came out so great! I am so happy! Thank you for make my day.
These were fun to make with my kids and so delicious!
Wow so good! You should let them set a few hours if you want a rich flavor and add kosher salt on top when there all most baked.
These are amazing. I am about to make a batch for my mom! Thank for sharing it.
Super excited to try this recipe. Heath bars are one of my favorite candy bars and I don’t think I’ve ever since a recipe that included them. Looking forward to trying this out and thanks for sharing it!
It seems like the baking time in the recipe has been changed – it says 10-12 minutes. In a 9×13 pan, that results in warm dough, but it’s no where near done. Is it possible to update the recipe with the approximate cook times for the pan sizes noted? I’m left searching through the comments trying to adjust as I’m baking.
Thank you!!
Cook time says 12 mins.? The bars are very raw in the center!
Thank you for the recipe nut it was toooooo salty for my taste.
