Peanut Butter Blondies

My second peanut butter recipe in a week’s time, and yet it seems like it’s been so long! I guess that’s life when you’re a teensy bit of a peanut butter-holic. The good news is that if you share my peanut butter affliction, you’ll certainly be in peanut butter heaven as soon as you take one bite of these. Using a traditional blondie base, crunchy peanut butter is added, and then chopped peanuts, and then (we’re not done yet) – peanut butter chips. A great big mouthful of soft, chewy, peanut butter goodness in each and every bite. These are absolutely a peanut butter lover’s dream.

Save This Recipe
Like all blondie (and most brownie) recipes, one of the best things about this recipe is how quick and easy it is to make. You don’t need to haul out the big mixer, nor do you need any special equipment. Just two bowls, a whisk, a spatula, and you’re set!
If you’d like to break up all of peanut butter-y-ness with another flavor, feel free to throw in 1 cup of chocolate chips along with the peanut butter chips. I think any type of chocolate would be good – milk, semisweet or bittersweet. Customize to your liking!

Peanut Butter Blondies
Ingredients
- 1½ cups (187.5 g) all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon (0.5 teaspoon) salt
- 8 tablespoons unsalted butter, melted and cooled, (½ cup )
- 1½ cups (330 g) light brown sugar
- 2 eggs, at room temperature
- 4 teaspoons vanilla extract
- ½ cup (129 g) crunchy peanut butter
- ½ cup (85 g) peanut butter chips
- ¼ cup (36.5 g) salted dry-roasted peanuts, chopped
Instructions
- Preheat oven to 350 degrees F. Line a 9x13-inch baking pan with foil, allowing excess foil to hang over pan edges. Grease foil.
- Combine flour, baking powder, and salt in a small bowl; set aside.
- In a separate large bowl, whisk the butter and brown sugar together until smooth. Add the eggs and vanilla and whisk until well incorporated. Whisk in the peanut butter until combined. Switch to a rubber spatula or wooden spoon, add the flour mixture and stir until just incorporated. Add the peanut butter chips and peanuts and mix until evenly distributed.
- Scrape the batter into the prepared pan and smooth the top. Bake until a toothpick inserted into the center comes out with a few moist crumbs attached, 30 to 35 minutes, rotating the pan halfway through baking. Cool completely on a wire rack for at least 2 hours. Using the foil overhang, lift the blondies from the pan and transfer to a cutting board. Cut into squares. Store in an airtight container at room temperature.

Michelle,
You love peanut butter? Well, I’ve been making Peanut Butter Breakfast Bars for 20 years. My family has always been “nuts” about them. My kids are grown up and married but my husband whines when I don’t make them. I got the recipe from Sunset Magazine. They are wonderful when you need something quick. Add a smoothy and what a great start to your day!
Peanut Butter Breakfast Bars? Sounds heavenly! :) I am a pb fanatic & also only buy the natural, but most recipes call for the “other” stuff. I did a Google search for the brkfst bars that you mentioned, but came up empty :( Would you mind sharing? :))
Mmm, fabulous as always! My wife looves peanut butter and would adore these :)
I’m thinking of halving the recipe (or better yet, making these in a larger pan) and top with a good brownie recipe, then bake. Super dee dooper delicous, I bet. You should try this as your next experiment. :D
Oh these look so good! I’d have a really hard time sharing these :)
I definitely can relate to being a peanut butter-aholic! Looks like a great recipe; so creative to use three different peanutty flavors :)
These are seriously heaven-sent. LOVE blondies and I have a great recipe for them but I will have to try these. (p.s. I love Skippy brand peanut butter, too ) :)
I wish we had peanut butter chips in England!!! Heck, I wish we had chocolate chips in England! Of all the blogs I read, yours always makes me most homesick for American things. And that’s a compliment :)
Aw, thank you! :)
I love blondies, they are my new obsession! And I LOVE peanut butter. Chocolate chips would be great in here too, but you can never go wrong with plain peanut butter!
I love a good peanut butter blondie…these look amazing!!! Thank you for making me drool since I haven’t eaten lunch yet:-)
OMG the description of these blondies alone is making me drool. Sounds amazing! I’m totally in love with blondies & peanut butter. Can’t get much better then that!!
A yeah, definitely a PB lovers dream. My dream! I like your suggestion for adding chocolate chips too. Me and these blondies = match made in heaven. Yummers!!!
Eh… YUM!!
Peanut butter, peanuts, and more peanut butter? My heart just started beating a little bit faster! I love blondies, but this just takes them to a whole new level! I can always lose weight next year! :)
Oh my gosh so much peanutty goodness!
Michelle, I’m curious to know if you have a brand preference in peanut butter? Do you go for or avoid natural blends? And if you use natural, do you use the truly natural that would require a stir before use?
I’m guilty of just buying what’s on sale, but as I’ve started trying to use better chocolate, I think I should also aim for better PB choices.
Thanks!
Hi Holly, Well, here goes… I grew up in a strictly JIF house and that’s all I really ate up until a couple of years ago. Since then I started experimenting with others and really wanted to move to natural peanut butter. This is where I am now… I love Smuckers (both creamy and chunky) natural for everyday/eating. I also found Peanut Butter & Co this summer (also natural) and LOVE their cinnamon raisin, as well as “bee’s knees” (peanut butter w/honey) as a sometimes treat. That being said, I never bake with natural peanut butter due to the excess oil that can sometimes collect. If you choose to bake with natural, just make sure that you use the no-stir kind that can be kept at room temperature (JIF and Skippy both sell these). For baking, I recently read that Cook’s Illustrated did a taste test of peanut butters and found Skippy to be their favorite. I bought a jar and really did like it, so now I use regular Skippy for baking. Sorry that was such a long answer to a seemingly simple question!
That’s a perfect answer! I appreciate your time!
These look beautiful. I would definitely add the chocolate because, obviously, I love chocolate!
peanut butter and I have a dangerous relationship. These look great!
One word: WOW!!
Blondies ;)
Loving your PB kick! Would down the whole pan of these blondes :)
The peanut butter lovers in my life thank you for this.
Given that I could go swimming in peanut butter I am a huge fan!
Peanut butter. Never grow tired of it. These look like a good chew and heaven with a glass of milk.
I have to make these! Unbelievable! I have had only one blondie in my life, and it’s time to change that! I love the combo of peanut butter, pb chips and nuts! This little bar, should give you lots of energy!!! Oh, can’t wait to make it!!
Awesome…the look so stunning and tempting.
The perfect blondie in my opinion!
These look delicious!
I think I would have to add milk chocolate chips though, just because I am a chocolate and PB addict;).
Have I died and gone to Heaven! These bars will turn anyone into a peanut buttery holic. These cookies are the bomb! These cookies are the answer to world peace!
I just came from The Girl Who Ate Everything who just made your PB Cookies. And now you’ve made PB Blondies. Being that I LOVE PB and put it in just about everything, these are perfect! :)
Honestly, this is just what the doctor ordered! They look so rich and nutty!
