Brownie Bark

by on October 5, 2012 · 42 comments

Last week my friend Nancy (Tag Sale Tastes) and I were discussing our favorite brands of packaged cookies.  I told her my favorite cookie was an Oreo, and she told me hers was a thick, crispy, chocolate cookie brittle she discovered at Central Market.  Nancy was so in love with it that she sent me a bag.  The whole family loved it.

Rather than drive to Central Market for more, I decided to try coming up with my own recipe.  What I liked about the brittle Nancy sent me was that the flavor was very much like a brownie and the texture was extra crispy without being greasy or having any sort of burnt taste.  After making 5 different versions, I settled on this one.  It’s not exactly the same as the cookie Nancy sent me (which I’ve since seen at Costco), but it’s really good. Since creating this one, I’ve come up with a peanut butter brittle/bark called Monster Bark and a Snickerdoodle Cookie Bark.

Brownie Bark
Recipe type: Dessert
Cuisine: American
Serves: 8
  • 2 large egg whites
  • 1/2 cup granulated sugar plus 1 ½ teaspoons granulated sugar
  • 1 1/2 tablespoon of Hershey’s Dark cocoa powder
  • 1/4 cup of vegetable oil
  • 1/4 teaspoon of vanilla
  • 1/4 teaspoon of salt
  • 1/4 teaspoon of baking powder
  • 1 tablespoons of nonfat dry milk powder
  • 1/2 cup all-purpose flour -- make sure to aerate and stir before measuring.
  • 1/2 cup of dark chocolate chips plus a couple of tablespoons extra
  1. Preheat the oven to 325 degrees F. Line a heavy duty 13x18 inch baking sheet with nonstick foil or parchment paper.
  2. In a mixing bowl, whisk the egg whites until foamy. Gradually whisk in the sugar, then whisk in the cocoa powder, oil and vanilla until smooth. Whisk in the salt and baking powder (making sure the baking powder doesn’t clump), then whisk in the nonfat milk powder. Add the flour and stir until smooth, then stir in ½ cup of the chocolate chips.
  3. Empty batter onto the lined cookie sheet and spread as thinly as possible using the back of a spoon or scraper. Sprinkle a few more chocolate chips into areas where they did not clump together (the chips tend to congregate). Remember to try to make the bark as thin as possible.
  4. Bake on center rack for 20 minutes. Remove from oven. With a pizza cutter or knife, cut into pieces without separating – you want shards, similar to what you’d get if making peanut brittle. Return to oven for 5 minutes.
  5. Remove from oven and let cool completely. Pull apart. At this point, it should be completely crisp. If you are left with a few thick, chewy, pieces, return them to the oven and bake at 250 for 20 minutes, then re-cool. If your batter is thin enough the first time, you should not need the second bake.
For a double batch, I recommend making the recipe once, then repeating and baking on a second baking sheet rather than doubling the ingredients. I'm still testing larger batch sizes. Sometimes things go awry when scaling up. If you don't have any nonfat milk powder, just skip it. I think it adds a little crispness, but I forgot to add it to one batch and the bark was fine.

What a good idea!!

Anna October 5, 2012 at 11:30 am

Sue, I have a really good cookie brittle in The Daily Cookie, but I didn’t think of doing a brownie version. If you try this, let me know. I’ve made it 5 times varying the amount of ingredients, but there’s always room for improvement. I’m hoping people experiment and post results.

Nancy October 5, 2012 at 11:41 am

I can’t wait to try this recipe this weekend! They look fabulous!

Rhonda October 5, 2012 at 12:36 pm

We like the one bowl oatmeal cookies from last week so much, I baked a second batch yesterday.
This one looks good and maybe I can bake it while my grand daughter naps this afternoon. I’ve never heard of anything like them before.

Anna October 5, 2012 at 12:47 pm

Rhonda, I’m so glad you liked those! Did you use grapeseed oil or another type of vegetable oil?

Good luck with the bark. Also, if you just want a small batch, the recipe halves well.

cherie October 5, 2012 at 2:08 pm

Great idea – looking forward to trying it!

Karen October 5, 2012 at 3:17 pm

This I have to try!!!!! I don’t have Hershey dark cocoa but I think when I make it I will use a touch of the chocolate extract that you, Anna, MADE me get! LOL.

Caralyn @ glutenfreehappytummy October 5, 2012 at 8:38 pm

oh my gosh how creative and delicious!

Ela October 5, 2012 at 10:31 pm

This is something new to me. Did it remain crispy even after a day? Thanks.

Anna October 6, 2012 at 8:01 am

Hi Ela,

Yes, it stayed crispy. I think the lack of egg yolks helps in that department.

Martha in KS October 6, 2012 at 10:26 am

For Halloween, I think after breaking up the bark, you could drizzle on melted orange-colored white chocolate for a holiday look. Then all you need are some clear Halloween-decorated bags & you’ve got great goody bags.

Anna October 6, 2012 at 4:16 pm

I’m going to have to check Costco again. I did find it at Central Market here in Austin, though.

Sheila In MD October 6, 2012 at 4:21 pm

At my Costco it was on an end display by the Ghiradelli brownie mix….not anywhere near the other packages cookies or bakery stuff!

Heather of Kitchen Concoctions October 6, 2012 at 5:49 pm

Oh what a great idea! Brownie Bark! Brownies are my favorite treat, so I can’t wait to try this. And I love Martha’s idea to make this a Halloween treat with drizzled orange and white chocolate.

Carolyn October 7, 2012 at 11:41 am

I have this in the oven as I write this. Thinking that this could be good at Christmas with the addition of a bit of mint extract.

Anna…. would an oatmeal cookie bark be possible?

Thank you for feeding my cookie passion with so many yummy recipes?

Anna October 7, 2012 at 12:13 pm

Hi Carolyn, I’m really looking forward to your opinion! Let me know if you think it needs to be thinner/crunchier/sweeter/less sweet, because there are lots of different ratios that can be used. Oatmeal bark would be fun! I’ve seen versions of it here and there (maybe called oatmeal brittle?) but I don’t remember trying it.

Carolyn October 7, 2012 at 7:42 pm

Hi Anna — this is fantastic. I think you have the correct ratios… it’s not too sweet, nice texture, good intense chocolate flavour… Thank you for another winning recipe! I’ll see if I can hunt down an oatmeal version.

Anna October 7, 2012 at 8:12 pm

Hooray! Glad you like it!!! I bought a bag of Sheila’s today and did a comparison. Mine is much thicker and more like a cookie, while hers is sweeter and brittle. It fits its name. I liked both. About that oatmeal version, I think I saw it in a Helen Corbitt cookbook, so I’ll go dig it up. Helen’s is more like an oatmeal lace cookie brittle and definitely more of a brittle than a bark.

Sheila October 8, 2012 at 2:36 pm

Heh..heh…took my large bag from Costco to a dog agility trial I was competing in as it was WAY too dangerous to have at my place given I live alone…all that tried it agreed a better name for it would be Brownie Crack as it is INCREDIBLY addicting!

JEANNE December 30, 2012 at 7:00 pm

I just bought a 4 oz. package of this Brownie Brittle at Wallly World on sale for under $2.00. It’s awesome!

Debbie January 23, 2013 at 2:26 pm

Omg this are the best you can buy them at Costco

Robin January 23, 2013 at 3:11 pm

Made these today. Came out great but any way to make them more chocolatey like Sheila G?

Anna January 23, 2013 at 3:14 pm

Hi Robin,
You could try adding more mini chocolate chips, that might help. Personally, I thought they had enough chocolate and I’m a chocoholic. Sheila’s seemed sweeter to me, and definitely lighter textured.

Torrey May 2, 2013 at 12:35 am

Hi Anna,

Loved the idea, and just pulled mine out of the oven. After reading the comments, i used 3/4 cup sugar, and no powdered milk. I must say they are VERY GOOD! Thank you for sharing!!

Anna May 2, 2013 at 8:34 am

Thanks for the variation! Good to know for people who out of or don’t want to buy the dry milk.

Brooke May 9, 2013 at 2:53 pm

Thanks for this recipe! I had this stuff before a Costco and it was amazing! I quadrupled this recipe and it turned out great!

Anna May 9, 2013 at 2:56 pm

Glad the quadrupling worked!

Tami May 9, 2013 at 6:23 pm

OMG Sheila’s Brownie Brittle. It is definitely addicting. I can’t stop sneaking into the kitchen for more. It’s almost embarrassing. Definitely like brownie crack. It’s definitely a Costco find. On line it is $12.99 for a pound not including shipping and only $6.99 at Costco.

Ronica June 27, 2013 at 4:19 pm

I had some brownie brittle recently, and loved it, so was very excited to try your recipe. It is delicious! Different, yes, but very good. My kids love it, too. :)

Some things I learned from making my second batch:

Foil might be easier to spread upon: parchment paper slides a lot. It is nice, however, to slide it off the pan to cool when it comes out of the oven. (Faster into my mouth. Haha)

Sprinkle the chips after spreading. It makes the spreading a lot easier.

If you mix the ingredients minus the sugar, baking powder and egg whites first in one bowl, then mix the sugar and egg whites until they are at soft peaks, then mix the baking powder into the chocolate mixture and drizzle it into the egg whites while mixing to blend, it will be fluffier and a bit easier to spread. The trade off is another bowl to wash.

When scoring, cut in pretty small pieces (like 1.5 inches square.) It’s much richer than I expected!

Also, I used Ghirardelli cocoa and it was fantastic. I think it would also be really good with a bit of espresso powder to really intensify the chocolate flavor.

Thanks for the great recipe! Not only do we have tasty treats, my house smells AWESOME!!! :D

Rachel August 2, 2013 at 10:35 pm

I used higher quality baking cocoa and Ghirardelli semisweet chocolate chips that I sprinkled on top. It turned out AWESOME! It also works well on a silicone baking mat so you don’t have to fight with foil or paper.

Anna August 24, 2013 at 6:33 pm

Holly, I hope you like it! I’ve made it many, many times since I came up with this version and it’s pretty adaptable to variations. I like it drizzled with melted chocolate. Mine is definitely different than Sheila’s, though. Hers is so thin and light, while this one is crunchier and more cookie-ish.

Carolyn August 24, 2013 at 6:39 pm

The version of this I made last week using a chocolate cake mix is closer in taste and sweetness to the Shelia G’s version. I find this stuff crazy addictive (especially sprinkled with some Maldon salt before baking).

Sue January 5, 2014 at 5:46 pm

I made this recipe this afternoon and it turned out really great. My husband, son and I all LOVE it. I substituted mini m&m’s for the chocolate chips because I had them on hand. My only regret is that I waited so long to try this. Thanks for the recommendation Anna! This is a keeper recipe.

Ramona February 19, 2014 at 2:34 pm

I just discovered your recipe here after buying “brownie bark” at our local Food Lion!
We just love it and want to make it ourselves since it is expensive and will be a seasonal thing where we live.
I would like to use a brownie box mix that I have in my pantry as the base for making brownie bark!
Has anyone tried to do this already and what was their results?
The recipe calls for 1-2 eggs and I am guessing to just use egg whites.

Anna February 19, 2014 at 2:53 pm

Hi Ramona,
I haven’t tried it yet, but I’ve seen it done. My reason for using the egg whites was for a little extra crunch. Yolks tend to add softness, but I wanted a hard and crunchy bark. If someone formulated a bark recipe with eggs, you might want to go ahead and do it the way that person suggested. If it’s not hard and crunchy enough for you, go with the equivalent amount of whites. Have fun with the boxed version! Let me know how it works out.

Ramona February 20, 2014 at 12:52 am

Hi Anna,
I just baked a batch tonight.. based on the amount of flour in the box mix I upped
the egg whites to four..and added more water to the mix..
I ended up cooking them 40 minutes total; two times 20 plus the 5 minutes after scoring..they are real crunchy but are more of a cookie crunch than a bark crunch..
does that make sense?
I may try your recipe next to see what it’s like and then try another store mix that I bought from Sam’s club late last year!
Regardless, my husband likes them!

Anna February 20, 2014 at 8:35 am

Hello Ramona,
Thanks for the update! It sounds like the person that came up with the box mix recipe knew what they were doing when they called for whole eggs. I suppose whatever is in the mix needs that little bit of tenderizing or softening from the yolks. My scratch recipe does not, which is why I used whites. I would love for you to try the scratch version and compare it with the box version. I’m sure they are both good, but I think you’ll find the scratch version to be less crunchy. It it crunchy, but not tooth breakingly hard.

Ramona February 20, 2014 at 9:20 am

Thanks Anna,
I guess I will be baking several more batches…you and your friends are really creative…my husband doesn’t care…just as long as I keep on baking! (He loves cookies!!)
Last night I went back and read all the posts and got a few more ideas…
This is fun!

Shirley March 13, 2014 at 4:51 pm

I make brittle with brownie mix, I use coffee in place of water a little more than called for,

Gerard March 31, 2014 at 1:56 pm

I dont think I have nonfat dry milk power, would ordinary powdered milk work?

Anna March 31, 2014 at 2:18 pm

I think it would be fine. Good luck!

Felicity October 8, 2014 at 10:26 am

I made this. I used 3/4 cup sugar, no powdered milk, and subbed sweet potato puree for the oil. It worked. The kids ate it up and said I could make it again.
Thank you.
