Peanut Butter Blondies are full of peanut butter, with a buttery and soft center. They are super easy to make and loved by everyone!

If you like ooey-gooey melt in your mouth bars, you should try my classic Blondies Recipe and as well, the very popular Chocolate Peanut Butter Brownies and Mousse Brownies.

Chewy Peanut Butter Blondies Recipe

Peanut Butter Blondies are such a classic and amazing dessert. Easy to make, you can never go wrong with it. The addition of brown sugar gives them a caramel flavor that combines so well with the peanut butter.
 
These blondies are chewy, creamy, dense, and loaded with peanut butter. The recipe calls for creamy peanut butter, mini peanut butter cups, and as well Reese’s pieces.
 
Each bite is filled with a different texture, soft, dense, with a crunch from Reese’s pieces, and the nice surprise of the melted mini peanut butter cups.
 
This dessert can be easily made ahead of time, it is great to take to potlucks, or make a double batch and freeze some for later.
 

How to Make Peanut Butter Blondies

  1. Prepare the working area: Get the ingredients, make sure they are at room temperature. Preheat the oven to 350F and prepare the baking pan.
  2. Make the Batter: Start by combine melted butter with the sugars, followed by the eggs and vanilla extract After that, add the flour, baking powder, and salt. Fold in Reese’s pieces and mini peanut butter cups.
  3. Bake: Transfer the batter into the prepared pan and bake at 350F for 30 minutes. Let cool completely before serving.

Blondie Recipe Variations:

This recipe is easily adjustable and many add-ins are possible and recommended. Here are some of the best variations of this delicious dessert:

  • Chocolate Chip Blondies: If you are a chocolate lover, add half a cup of chocolate chips to the batter. Then, follow the same cooking steps. 
  • Vegan Blondies: For a vegan version, simply swap the eggs with a chia egg. Similarly, replace the honey with about half a cup of coconut sugar. 
  • Add nuts: For a crunchier texture, add your favorite nuts to them. Pecans, walnuts, almonds, or even pistachios. 
  • Original Chewy Blondie Recipe: If you are looking for the classic recipe, then try our famous recipe by clicking here.

How can you tell when they’re cooked?

The best way to check the doneness would be to insert a toothpick once they are baked. If it comes out mostly dry, they are ready. Just remember that they will dry out a bit as they cool.

What’s the Difference Between a Brownie and a Blondie?

Both are similar in texture as they are both gooey and chewy. The main difference between the two is that brownies contain cocoa powder, and are more chocolaty in flavor. On the other hand, blondies are more buttery with a hint of vanilla flavor. 

Which Peanut Butter is Best for Blondies?

The BEST peanut butter for cookies is always the creamy variety. I would recommend going with Jif or Skippy.

HOW TO STORE AND FREEZE Peanut Butter Blondies?

  • They can be kept at room temperature in an airtight container for about 5-6 days. 
  • To refrigerate: Use an airtight or sealed container, and then refrigerate for up to 10 days. 
  • To freeze: Wrap the sliced blondies in plastic wrap, and then transfer to an airtight container or freezer bag. Place in the freezer for up to 6 months.

Recipe Tips:

  • As stated above this dessert is easily modifiable. You can add your favorite add-ins, like chopped walnuts, white chocolate chips, etc. 
  • Also, coffee extract or cinnamon can be added to the batter. 
  • I would recommend placing the blondies in the fridge to cool them down faster. 
  • For the topping, you can use some caramel or even sprinkle them with some sea salt on top for a contrast of flavors!

I made these last night and they were AMAZING! Peanut butter is what Blondies have been missing this whole time! I'm allergic to chocolate, so have tried to make Blondies since I can't eat Brownies. They're all so dull (butterscotch, yuck) that they weren't worth the trouble. Until now! I altered only one small thing-- I subbed white chocolate Reeses for regular. I cut regular sized cups into 1/6ths, and folded them in. Except I also used regular Reeses on one side once I had the batter in the dish, because my husband can eat chocolate. I just pressed them into the batter. I rarely bake, so having all the steps explained was very helpful. And putting down parchment paper These? Brilliant! It made the bottom & sides perfectly crisp (in a good way) and the dish took 2 seconds to clean. These will become a favorite, I can tell. I took photos, too, they were so pretty!

Hi Catalina, I wasn't kidding when I said I found Blondies boring, even though I can't eat real chocolate. We have been enjoying these all week! Is there a way to post a photo or 2 with my review? I took one of entire baked dish & then 1 of a plate with my white chocolate square on one side, and my husband's chocolate piece beside it. Thanks & have a great weekend!
