Peanut Butter Chocolate Chunk Cookie Bars – All the flavor and texture of peanut butter-chocolate cookies, but much faster and easier. The batter comes together in minutes by hand and in one bowl. In under 30 minutes, from start to finish, you can be eating one of these bars.
Sometimes I think there’s no new way to combine peanut butter and chocolate.
But then I put my thinking cap on and something always comes to me.
I was craving something dense, thick, peanut buttery and chocolaty, and very easy. I wasn’t in the mood for stand mixers and dough chilling. I wanted something fast and not fussy in the least. Sometimes I can handle tedious baking projects and other times, I have the patience of a flea.
I planned to use browned butter in the batter and finish them with a melted peanut butter-chocolate chip drizzle, but kept them pretty bare bones and am so glad I did. The peanut butter flavor comes through, and the glorious hunks and chunks of dark chocolate shine in every bite.
They’re made in one bowl, no mixer required, and the batter comes together by hand in five minutes. After a short 20 minute stint in the oven, you can be enjoying big chewy bites. I love recipes that don’t require hours of advance planning and that go from cupboard shelves and into my belly in under 30 minutes flat.
They combine many favorite recipes into one. They remind me of a pan-full of peanut butter-spiked Browned Butter Chocolate Chip Cookie Cups. As an aside, if you’re prone to cookies that spread, it’s impossible with those because they’re baked in muffin cups.
I love the soft, fudgy density of Peanut Butter and Jelly Blondies and this recipe is reminiscent of those, but because I used a pinch of baking soda and slightly more flour, they have more of a cookie-bar than a blondie texture. And, they’re loaded with chocolate chunks like my favorite Peanut Butter and Chocolate Chunk Cookies.
To make them, melt the butter, about 1 minute in the microwave. Stir in an egg, sugars, vanilla, a hearty scoop of peanut butter, and the dry ingredients. After the batter comes together, fold in chopped dark chocolate. I used Trader Joe’s Dark Chocolate Pound Plus Bar. I love their Pound Plus Bars for baking and the 72% and the Dark Chocolate are my two favorites.
A tip when chopping chocolate is to put a piece of parchment paper on your cutting board before chopping. It makes it so easy to pick up and dump the whole shredded mess into your mixing bowl. Chocolate isn’t able to cling to the cutting board, making cleanup much easier. I chop many batches of chocolate on the same piece of parchment and tuck it inside the wrapper of my leftover chocolate bar for next time. I hate to waste, even paper.
After the chocolate is folded in, transfer batter to the pan, and bake for about 20 minutes. Don’t overbake because the bars will set up in the pan as they cool. A toothpick test may or may not work because there’s so much chocolate in them and I had to insert a toothpick in four different spots until I stopped hitting chocolate and struck dough. Not a horrible problem to have.
They have all the benefits and taste of Peanut Butter Chocolate Chunk Cookies, but faster and easier. I love pans of bars because there’s no dough to chill or form into individual mounds. No mixer dishes to do, and nothing can accidentally spread out all over a cookie sheet since it’s baked a pan.
The flavor of peanut butter is distinct and present but not overwhelming and doesn’t overshadow the buttery, sweet dough. The edges raised up and puffed a bit while baking and turned chewy, yet the interior remained dense, tender, moist, and soft.
The chocolate chunks are beautiful surprises that you can sink your teeth into in every bite.
There are so many ways to doctor these up, from using browned butter rather than melted, or adding white, butterscotch or peanut butter chips. Sprinkle in a handful of marshmallows, M&Ms, or a favorite candy. The dough is ripe for add-ins.
Before serving, drizzle with chocolate, melted peanut butter or melted chocolate peanut butter. After the photos, I drizzled some Dark Rum Caramel Sauce over the top on a whim. Oh my, highly recommended and if only I gotten a picture. You’ll have to use your imagination or just make some for yourself.
Those center cut bites are my favorite. Under-baked, gooey, rich, and flanked with hunks of dark chocolate.
Even after writing a cookbook with 100 Peanut Butter Recipes I don’t think I’ll ever run out of ways to combine peanut butter and chocolate.
They’re my favorite food groups.

Peanut Butter Chocolate Chunk Cookie Bars
Ingredients
- ยฝ cup unsalted butter, melted (1 stick)
- 1 large egg
- ยพ cup light brown sugar, packed
- ยผ cup granulated sugar
- 1 tablespoon vanilla extract
- ยฝ cup creamy peanut butter heaping, like Jif or Skippy, do not use homemade
- 1 ยผ cups all purpose flour
- ยฝ teaspoon baking soda
- pinch salt, optional and to taste
- 6 ยฝ ounces dark or semi-sweet chocolate, roughly chopped (I used Trader Joe's Dark Chocolate Pound Plus Bar, 54%)
Instructions
- Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.
- In a large microwave-safe bowl, melt the butter, about 1 minute. Allow the butter to cool momentarily so you don't scramble the egg. Add the egg, sugars, vanilla, and stir vigorously to combine, for about 1 minute. Stir in the peanut butter. Add the flour, baking soda, optional salt and stir until just incorporated. Stir in chocolate. Turn batter out into prepared pan, smoothing it lightly with a spatula. Bake for 18 to 22 minutes, or until center is just set and golden (a toothpick test should come out clean if you hit dough but because of the abundance of chocolate, hitting chocolate is more likely). Bars will firm up more in pan as they cool.
- Allow bars to cool in pan for at least 30 minutes before slicing and serving. Store extra bars in an airtight container at room temperature for up to 1 week, or in the freezer for up to 3 months.
- Bars may be kept gluten-free by replacing the flour with your favorite gluten-free baking blend.

Mmm chocolate and peanut butter is my favorite! Definitely never gets old. I’m writing a whole magazine article on my love of the two flavors (and a ridiculous chocolate PB cake recipe), and I bet I could write a cookbook on it. Haha! Sooo good. These look phenomenal! Definitely trying…pinned.
What a fun article to write! And thanks for the pin!

Averie, these look sooooo good! Is there a greater combination than peanut butter and chocolate? I think not.
PB & Jelly is good but I think PB & C wins :)
I was having a terrible day and decided to make these about an hour ago. Greatest decision ever!
I am so glad to hear that they turned your day around! Thanks for coming back to LMK you tried them!
i immediately knew these were yours when i saw them on foodgawker… they are literally making my mouth water.
i love your thought about using browned butter. i might just have to try that out! :)
Love that you were able to recognize them on FG :) Thanks for saying that!
I long for these bars now! I just became the GM at my work (2 pubs) and needless to say I have been super busy! And these bars look perfect for my schedule! Because some times you want a big ol hunk of cookie and do not have the time or energy to make 36 individual ones! These look great! I absolutely love how dense and moist they look, perfect to sink my teeth into! Maybe even re heat and top with ice cream!
Pans of bars are always what I prefer to make. For some reason, people like cookies and are drawn to them, but if I had my choice, bars are so much faster/easier and you still get the same texture benefits chewy edges/soft middles!
I love ALL of your chocolate and peanut butter recipes. These look super tasty!
I love how all your bars and cookies look fudgy – even when there’s no fudgy. Like they are super soft and delightful! I cannot wait for your cookbook!
keeping baking soda/powder out of bars is one way and making sure not to overcook is another way…b/c I hate a dry, airy, cakey bar…ick! lol
Wow! I have to say, your bars always look so perfect! Little squares of deliciousness! And you can never go wrong with PB and choc combo! And your book!! I can’t wait to get my hands one a copy!
I am convinced that peanut butter and chocolate make for theeee best combo!! :)
If it looks like it and does not consume much of time, it could not be better :)
They’re the best food groups :D
I love how simple and easy and GORGEOUSLY delicious these are!
As much as I love the challenge of a complicated recipe, nothing can replace the joy of a simple one bowl dessert. These bars looks fantastic, you can’t beat a peanut butter-chocolate bar!
Your cravings lead to very good things! Love how they’re bursting with chunks of chocolate! They look awesome, Averie!
I’m SO glad that you keep putting that thinking cap on, because I just LOVE the combinations that you keep coming up with, PB and chocolate wise! Seriously, these bars just look so dense and luscious – I can’t imagine anything better! FABULOUS recipe!
You’d think after a book of it, I’d be tapped. But I feel like I’m just getting started!
