Chocolate Peanut Butter Cookie Bars

The other night I got this really weird urge to mix peanut butter with sweetened condensed milk. Like, I could not live another moment without that strange concoction in my life.

So, I did. Because it’s my job.

Yes, I am lucky enough to call succumbing to my strange cravings at 10:30pm my job. It’s a pretty good gig, if you ask me.

So, what I did was whip up some basic chocolate chip cookie dough (grabbed the recipe right off the back of my Hershey’s bag of chips), minus the chocolate chips. Then I mixed together some goopy condensed milk and peanut butter and then I drank it with a straw.

Actually, no, I did not. I ate it with a spoon. It was way too thick for a straw.

I topped the cookie dough with the peanut butter glop and then I baked it all up into this ridiculous union of peanut butter and cookie dough.

We all know that you can’t have peanut butter and cookie dough without a bit of chocolate, though, so I took the sad little bag of chocolate chips that had gotten left out of the dough and I sprinkled them on top of the baked dough, waited for about 5 minutes, and then smeared them in with an offset spatula. <—Longest sentence ever.

Chocolate. Peanut Butter. Cookie. Bars.

Yes. Put these in your next holiday cookie exchange and watch people fall in love with you. Or just eat them all yourself and call it a day. ‘Tis the season!

Chocolate Peanut Butter Cookie Bars


1 cup (2 sticks) butter, softened
3/4 cup granulated sugar
3/4 cup packed light brown sugar
1 teaspoon vanilla
2 eggs
2 1/4 cups flour
1 teaspoon baking soda
1/2 teaspoon salt
1/2 cup peanut butter
7 ounces (half can) sweetened condensed milk
2 cups (11.5-oz. pkg.) HERSHEY'S Milk Chocolate Chips


Heat oven to 350 degrees. Great a 13x9 baking dish with cooking spray or line with parchment.
Cream together the butter and sugars until light and fluffy. Beat in the eggs, one at a time. Add the vanilla and mix to combine.
In a small bowl, combine the flour, baking soda, and salt. Slowly add the flour mixture to the creamed butter and mix until well combined.
Spread the cookie dough into the prepared pan.
In a small saucepan over low heat whisk together the condensed milk and peanut butter until melted and combined. Pour the mixture evenly over the cookie dough and use a butter knife to swirl the mixture throughout the cookie dough.
Bake for 25-30 minutes or until the dough is lightly browned and cooked through. Remove from the oven and pour the chocolate chips in an even layer over the cookie bars. Let sit for five minutes before smoothing out the chips with an off-set spatula.

This recipe was created as part of an on-going partnership with Hershey’s. More recipes, a giveaway, and a video of me sharing cookie tips will all be coming up in the next month, so stay tuned!

    Haha, I could totally eat that mixture with a spoon. And I have some fairly large kiddie straws in my junk drawer that might even allow me to drink it. :-) Although adding it to these bars sounds so freakin good.

    I definitely need to start calling my late night craving satisfaction “work”. Then maybe my boyfriend won’t question my peanut butter/biscoff/dulce de leche consumption so much!

    Hi Karly! I am so sorry that I have gone most of my life without knowing about your blog. I fixed that last week and have been hooked ever since.

    I just wanted to say that you crack me up, and that I really enjoy your blog. Plan on me being a regular from now on. Not irregular. A regular. There’s a difference, right?

    And you’re correct…way too thick for a straw.

    I just made these and theywere delicious! But, they came out more cakey then cookieish! What can i do to make them more cookieish?

      Hi Erica!

      Glad you enjoyed them!

      You’ll want to make sure you’re measuring your flour correctly. Spoon it into the measuring cup instead of scooping it out. Scooping tends to compress it, so you end up with more flour than you need and that will make for a cakey cookie.

      Did you use real butter in the recipe or margarine? I always use real butter.

      You can also try swapping out the white sugar for brown and chilling the dough before baking.

      Hope that helps!
