Gooey Chocolate Chip Sandwich Bars… Cookies for Kids’ Cancer Cookbook

September is Pediatric Cancer Awareness month, and today I’m sharing some Gooey Chocolate Chip Sandwich Bars. What do these goodies have to do with cancer? The Gooey Chocolate Chip Sandwich Bars come from the “Cookies For Kids Cancer: Best Bake Sale Cookbook.” I’m giving away 3 copies of this fabulous book– see the details at the end of this post…

The Cookies for Kids’ Cancer cookbook provides directions on how to hold a bake sale, signage, and lots of recipes and photos. The best part? All of the author’s royalties go directly to help fight pediatric cancer by funding research into new treatments and a cure. Author Gretchen Holt-Witt founded in 2007 when her two-year old son Liam was diagnosed with pediatric cancer. A few years and a few hundred thousand cookies and bake sales later, this charity has raised millions of dollars to help fun new pediatric cancer treatments. Kids helping kids… I like that.

These are slab cookies. Made in one pan and lifted out as a slab. Love that word- slab. Slab. Slab. (sorry)

They’re a little chocolatey.  SOOO good right out of the pan and warm and gooey, but rather hard to cut.  It’s best to chill them and them cut them neatly.  If you’re into being neat.

So let’s talk about the makeup of these bars.  They’re basically chocolate chip- oatmeal cookie dough spread into the bottom of a pan, then topped with a gooey chocolate layer, then topped with more chocolate chip- oatmeal cookie dough.  Hungry?  Craving chocolate now?  Yeah, I thought so.

I love the sort of natural, rustic crackle look on the tops of the bars.  Gives you a lil’ peek that there is a gooey layer of chocolate hidden in the middle.

And there they are… my “neatly” cut Gooey Chocolate Chip Sandwich Bars.  Chocolate overload, if you like that sort of thing.  Good with milk, if you drink that stuff.  And perfect for a bake sale, where you’ll make big bucks to donate to Cookies for Kids’ Cancer.  I think it’s a great idea for kids to have bake sales for charity– showing them that it’s not all about making money for themselves to purchase their next Wii game or iTunes gift card or whatever.  There are things much more important in this world.

I’m giving away three copies of the Cookies for Kids’ Cancer cookbook, courtesy of Wiley Publishing and three OXO Good Grips Good Cookie Spatulas, courtesy of OXO.  This giveaway is open to anyone who has a mailing address in either the USA or CANADA. Three winners will be chosen via on Sunday, October 2nd and will be contacted via email.  Each winner will receive a Cookies for Kids’ Cancer Cookbook and an OXO Good Grips Good Cookie Spatula.

This giveaway is now closed- randomly selected winners via are commenters #174, 144 and 188.  Congratulations!

Gooey Chocolate Chip Sandwich Bars


2 cups semi-sweet chocolate chips
One 14-ounce can sweetened condensed milk
2 teaspoons vanilla extract

1 cup (2 sticks) unsalted butter, at room temperature
1 cup light brown sugar
1/2 cup granulated white sugar
1 large egg
1 large egg yolk
1 tablespoon vanilla extract
2 cups all-purpose flour
1 cup quick-cooking or old-fashioned rolled oats
1 teaspoon baking powder
1 teaspoon baking soda
1 teaspoon kosher salt
3 cups semi-sweet chocolate chips


1. Preheat oven to 350 degrees F. Lightly butter a 9x13-inch pan with parchment paper, allowing enough overhang on the long side to lift the bars from the pan.

2. Prepare the gooey chocolate filling: Place the chocolate chips and condensed milk in a small saucepan over the lowest possible heat and cook, stirring constantly, until the chocolate has melted and the mixture has thickened, 3 to 5 minutes. Turn off the heat, add vanilla, and stir until smooth. Set aside to cool to room temperature.

3. Prepare the cookie dough: Place the butter and sugars in a large bowl. Beat with an electric mixer until smooth and creamy. Add the egg, egg yolk and vanilla. Beat well. Whisk together the flour, oats, baking powder, baking soda and salt in a medium bowl. Add to the butter mixture. Beat until everything is well incorporated, scraping down the sides of the bowl as needed. Stir in the chocolate chips.

4. Prepare the bars: Using half of the batch of cookie dough, place dollops into the prepared pan and press down lightly to even it out. Pour the cooled chocolate mixture over the dough and then add small dollops of the remaining dough on top. Don't worry if the dollops don't completely cover the chocolate mixture. Just spread it together as much as you can, and let some chocolate peek through.

5. Bake until lightly browned, 20 to 25 minutes. Set aside to cool completely, then cut into 32 bars.


*These are easiest to cut when they have chilled for a while. You'll be able to get nice, clean cuts when they're firmer, then they'll soften up a bit when they're at room temperature again.

    Your chocolate bars look so yummy! If at a bake sale I would likely go for something gooey and chocolate like them or anything with coconut. Anyone having a bake sale? I’m hungry.

    Thanks for sharing your talent and recipes with us.

    I love chocolate chips. Never had a choc chip sandwich though 🙂 I love the way you kept saying ‘slab’ and then I had the thought. OOOH, they look good enough to eat the whole slab. Which was quickly followed by the thought- not if you still want to fit in your clothes you don’t! :-)LOL
    Thanks for another yummy recipe 🙂

    Made these this weekend. Delicious. At first- I thought they were fantastic from the oven- very gooey. THEN I thought they were good right out of the fridge once they hardened- GOOD- THEN I thought they were fabulous from the fridge to the counter at room temo for an hour because the chocolate got fudgy. Will DEFINITELY make these again (after I restock my chocolate chip jar from this recipe!!!)

    This may be a stupid question but do the cookies call for 2 eggs?

    1 whole egg and then the yolk from another egg?

    • May 16th, 2012 @ 9:24 PM

      Yes, one large egg + one egg yolk without the white.

    HUGE hit in the office! To make them last a little longer (and hide them from my husband) I also saved a few in the freezer and they were delicious!

    I might cut back the chocolate in the cookie dough just a bit next time, but definitely a repeat. 🙂

    Oh my! I can’t wait to eat these! They just came out of the oven and look delicious! I altered the recipe a bit and used dark chocolate squares in the filling and put coconut on top (please don’t take offense, I alter every recipe I try to follow). Thanks for sharing with everyone!

    My mama used to make her regular chocolate chip cookie recipe in a 9 by 12 pan and cut them into bars. They were called bar cookies back then. Kept the house cooler in the summer than having the oven on baking regular cookies by the panful.

  35. postedOct 26, 2014 8:54 AM

    We used to make them in my HomeEc class, we used almost the exact same recipe and put it in a 9×9 pan, we called them yummy bars. They were very rich and yummy, hence our name for them 🙂

    I’ve looked at so many choc. chip bar recipes this morning, I honestly can’t remember how I got here – all I know is I started with Google LOL.

    But these are the ones that are in the oven. I think I messed up a couple things though. The chocolate sauce was super thick (not pour-able at all), and every search for ‘how to thin chocolate sauce’ led me to comments about seizing, so I just left it and spread it on the best I could. I also found the dough really dry so I added about 1/4 – 1/3 cup milk. Then I put way too much batter on the bottom layer, and didn’t have enough to cover the top. Oops! It was quite the gong show this morning LOL.

    Hopefully I didn’t completely ruin the recipe, and they still taste good!! Thanks for sharing!!

    I just made these!!  Oh my goodness, so much deliciousness!!  🙂
    In New Zealand it’s Anzac Day for us (a day of rememberance for those who’ve fought in wars for our freedom). So in the spirit of Anzac and to make this slice more Anzac-y, I made the base with a little less chocolate, added coconut and some golden syrup, and me oh my, it is so good.  Thanks for sharing this recipe with us all! 🙂

     I made this two days ago and it turned out great.

    I made these, it was really hard to spread the bottom so I had to use more batter, and the top looks awful because I ran out. They’re for a bake sale and I’m not sure how I’m going to salvage them. I really think you should adjust the cookie batter recipe so it’s not stretched too thin.
