Chocolate Peanut Butter Bars

My husband has been whiny lately.

Apparently I haven’t been making enough chocolate and peanut butter treats for him? He feels like it’s all caramel, all the time around here.

I will admit to a slight obsession with caramel lately, but I’m not out of control or anything.

Seriously. I can stop at any time.

To prove it, I made these insane cake mix bars. They are bursting with chocolate and peanut butter. The filling is so gooey and rich. The crust is full of peanut butter. These totally taught my husband a lesson.

And that lesson? If you whine enough, I’ll give you what you want just to shut you up.

I maybe didn’t plan that so great.

Chocolate Peanut Butter Bars


1 package (18.25 ounces) plain yellow cake mix
1 cup peanut butter
8 tablespoons butter, melted
2 large eggs
2 cups semisweet chocolate chips
14 ounces sweetened condensed milk
2 tablespoons butter
2 teaspoons vanilla


Preheat the oven to 325 degrees F. Line a 13x9 baking dish with parchment paper.
Place the cake mix, peanut butter, melted butter and eggs in the bowl of your stand mixer and beat on low speed for 1 minute. Stop the machine and scrape down the sides of the bowl with a rubber spatula. The mixture will be thick. Reserve 1 1/2 cups for the topping. Transfer the remaining crust mixture to the pan. Using your fingertips, press the crust evenly over the bottom of the pan so that it reaches all sides. Set aside.
For the filling, place the chocolate chips, condensed milk, and 2 tablespoons butter in a medium pot over low heat. Stir and cook until the chocolate is melted and the mixture is well combined, 3 to 4 minutes. Remove the pan from the heat and stir in the vanilla.
Pour the chocolate mixture over the crust, and spread it evenly with the rubber spatula so that it reaches the sides of the pan. Using your fingertips, crumble the reserved crust and scatter it evenly over the chocolate.
Bake until the top crust is light brown, 25 to 30 minutes. Remove the pan from the oven and cool on a wire rack for 30 minutes.
Cut into small pieces.
Store at room temperature for 3 days or in the refrigerator for up to one week.

    I agree with your husband.
    Although my second love is caramel, so I agree with you too.

    Holy crapola, those look super duper fudgy & awesome. I’m loving the crumbly top mostly because I have a crumbly top obsession I inherited as a little girl. But you know, only a minor obsession. 😉

    Choc & PB is a winning combo….Pretty much a day never goes by where I don’t have it! (or one or the other, for sure!)

      Hope the surgery goes well! I’ll be thinkin’ about ya.

    It seems like everyone is baking desserts using box mixes these days. I better jump on the bandwagon!

    I love caramel. I love peanut butter too, but I can not eat it, sadly. So I’m on Team Caramel! I’d love caramel and chocolate.

    What if you made him something with caramel, peanut butter AND chocolate? That seems like it would be ideal for all parties. Compromise is key! Though..I’m kind of in love with these. So maybe just leave them as is.

    I’m SURE these made your husband VERY happy!


  15. Jocelyn July 11, 2012 @ 10:31 pm (#

    I kind of get whiney myself if I don’t have peanut butter and chocolate in some form each week:-) I love how easy these bars are with the cake mix too. I have to say I love Joanne’s comment about caramel, pb and chocolate…now that’s a bar waiting to happen!!!

    Hi Karly: I love chocolate and peanut so these bars look so yummy. I am going to try them in couple of days and try not to eat so many and give some to my neighbors. I love all your recipes and contests!


  17. Elizabeth@ Food Ramblings July 12, 2012 @ 6:31 am (#

    Love chocolate and peanut butter together!!

    Hi Karly,

    Wow, thank you so much for sharing this recipe! I tweaked it a bit by adding a tsp of instant coffee granules to the chocolate filling and by spreading some peanut butter over the initial layer of crust before adding the chocolate filling on top. To DIE for!

    I love to bake, and I try to bake something every other week or so for a salsa dancing team that I practice with on Saturdays. Last night I made these bars, and (after more quality control than was necessary on my part…I had a fair sampling), I just can’t wait to share them today! I will also be making another batch this Sunday for a summer bbq I’m hosting.

    Thank you thank you thank you!

    Yum! I wanted to let you know that I featured this today in my “What I Bookmarked This Week” post. Thanks for the inspiration.

    The presentation of these dessert treats on ripped paper towels is tacky at best. Certainly not conducive to getting someone’s attention. You need to watch more Food Network shows.
