It’s all about the peanut butter in these rich and chewy Peanut Butter Blondies that are easy to bake and go great with a big glass of milk or scoop of ice cream!
Peanut Butter Blondies
These Peanut Butter Blondies give peanut butter its chance to shine and boy, does it! Rich, chewy peanut butter bars that bake up so moist in the middle. They’re impossible to resist. I rotate between my One Bowl Fudge Brownies and these blondies for a weeknight treat or a last minute get-together with friends. They get rave reviews and I get tons of requests for the recipe.
Pure Peanut Butter Bliss
I have to confess that when I make sweet treats with peanut butter in them I almost always combine it with chocolate. No chocolate needed in these, just pure peanut butter bliss. Of course, if you can’t resist that chocolate peanut butter combo, you could stir in some chocolate chips, frost them with chocolate or top one with a little chocolate ice cream. But they’re perfect as is.
One Bowl and 30 Minutes
These peanut butter blondies are so simple and are sure to become a favorite. One mixing bowl is all you need and just 30 minutes in the oven to pure peanut butter perfection. I use peanut butter flavored extract in them, but if you can’t find it on the baking aisle of your grocery store or supermarket, you can certainly use vanilla extract and the peanut butter flavor still comes through.
Grab your favorite peanut butter and get to baking. Simple yet so scrumptious!

How to Make Peanut Butter Blondies
- Preheat oven to 350°F. Lightly grease a 9×13-inch baking dish or pan with non-stick cooking spray and set aside.

How to Store Peanut Butter Blondies
Store leftover blondies in an airtight container on the counter for up to five days.
To freeze, wrap them individually in plastic wrap. Then place in a freezer-safe container or in individual freezer-safe baggies.
To defrost frozen blondies, let them set at room temperature, uncovered, so they don’t absorb too much of the moisture.

Hi! Your pictures look exactly how I want my PB brownies. If I wanted to use all natural, peanuts-only peanut butter, what do you think I would have to change to make the recipe work?
Thanks!
Hi Elizabeth! It should work great as long as the peanut butter is creamy and able to mix in well. Hope this helps. Enjoy!
Hey If I subtract an egg, would that make them fudgy instead of cake like
Hi Adriane! They are already pretty fudgy in texture. If you subtract an egg, they would be even more so. They should still taste great! Enjoy!
Ok thanks, Ill try them both ways, two eggs and three eggs
Do you recommend putting vanilla extract or extra peanut butter?
I would recommend vanilla extract as you would need to adjust the other ingredients to accommodate additional peanut butter for the texture to turn out. Enjoy!
This is a great recipe, but the bars were a bit too greasy for me. To fix this problem, I decreased the butter to 1/2 cup and they were perfect. I also like a thicker bar so the next time I made them, I calculated a 1-1/2 recipe, using 4 eggs plus 1 egg yolk. IMO, this was the perfect thickness for a 13×9 pan. I didn’t want to use a smaller pan because I wanted more servings. Thanks so much for a great recipe!
When you calculated 1-1/2 of the recipe, did you double the rest of the ingredients?
Hi Lily! If you’re wanting to make one recipe and then half of the recipe, you’ll want to put the full ingredients listed and then half of each ingredient to come to 1 and 1/2 times the recipe. Hope this makes sense. Enjoy!
I made them and love them I added a extra egg yolk and mini chocolate chips on top and loved it ☺
These were phenomenal! A total hit with my entire family. Great recipe!
I absolutely adore brownies, and the fact that these brownies are entirely peanut butter is blowing my mind a bit. And I kind of want to whip up a pan of my own so I can gorge myself tonight after a long day! Thanks for sharing!
