I’m a big fan of stuffed brownies and cookies! From my chocolate peanut butter brownies to my strawberry cheesecake cookies, I love creating recipes that are loaded with flavor. And these peanut butter stuffed blondies are no exception! 

Just like my Nutella blondies, the peanut butter is frozen before being sandwiched between two layers of blondie batter, giving you the perfect peanut butter stuffed blondies!

Why You’ll Love These Peanut Butter Blondies

  • These blondies with peanut butter are easy to whip up and you don’t even need a mixer.
  • You can easily make this dairy-free, so it’s perfect if you have food allergies.
  • This is the ultimate recipe for peanut butter lovers! I’ve also added some chocolate chips because chocolate peanut butter is one of my favorite combos. 
  • You only need 9 simple ingredients, nothing too fancy here.

Ingredients Needed

Peanut Butter Blondies ingredients in bowls
  • Butter: you can use regular butter or dairy-free butter. 
  • Chocolate Chips: these are totally optional but I love adding them here! I recommend using semisweet or dark chocolate chips, but peanut butter chips would also be amazing.
  • Peanut Butter: I suggest using commercial peanut butter, like Skippy’s or Jif, where it’s super creamy. I don’t recommend using natural peanut butter with the oil on top, it will change the texture of the blondies. You can also use crunchy peanut butter!
  • Flour: I’ve tested this recipe with all purpose flour, but if you’re gluten-free you can use gluten free all purpose 1-1 baking flour.

Step by Step Instructions

Peanut Butter Blondies process in six steps

Step 1: Line an 8×8 baking pan with wax paper. Melt the peanut butter in the microwave or on the stove. Pour the melted peanut butter into the pan and place in the freezer for 1-2 hours. You want it to be able to remove it as one solid piece.

Step 2: Once frozen, preheat your oven to 350°Fahrenheit. Take the baking pan out of the freezer and remove the wax paper with the peanut butter. Line the pan with parchment paper, making sure it overhangs. This will make it easier to remove the blondies once cooled.

Step 3: Melt the butter in a large bowl in the microwave or in a small pan on the stove.

Step 4: Add the granulated sugar and light brown sugar. Whisk together until it resembles a paste that pulls away from the side of the bowl.

Step 5: Add the eggs and vanilla extract and mix once more.

Step 6: Pour in the flour and salt and mix until just combined, make sure you don’t over-mix it!

Step 7: Gently stir in the chocolate chips.

Step 8: Pour half of the blondie batter into your prepared pan. Peel the frozen peanut butter layer off of the wax paper and place on top. 

Step 9: Pour the remaining blondie batter on top and spread it so it covers the peanut butter layer. Feel free to sprinkle over more chocolate chips!

Step 10: Bake for 25-35 minutes. The tops of the blondies should be crinkly and a toothpick inserted in the middle should come out with wet crumbs, but not batter.

Step 11: Let the blondies cool completely before slicing.

Expert Tips

  • I always recommend using a kitchen scale to weigh out your ingredients! It’s so easy to add too much flour if you use measuring cups, which will make your blondies dense and dry. Don’t have a kitchen scale? Then make sure to use the scoop and level method to weigh out your flour! 
  • Make sure to use wax paper and not parchment paper when you freeze the peanut butter layer! It’s a lot easier to peel off of wax paper than parchment paper.
  • When lining the pan for the peanut butter blondies, make sure it’s hanging over the edges of the pan. That’ll make it much easier to remove the blondies!
  • Let the blondies cool completely before taking them out of the pan or slicing them, otherwise they might just fall apart.

Storage Instructions

Store the blondies un-sliced in a pan, covered with foil, for 3-4 days. To store sliced blondies, keep them in an airtight container at room temperature.

To freeze, wrap them tightly in plastic wrap and then foil. Place in a freezer bag and freeze for 1-2 months. Let thaw at room temperature before enjoying.

Peanut Butter Blondies

These gooey and chewy peanut butter blondies need just 9 simple ingredients! These blondies are stuffed with peanut butter and packed with chocolate chips.

Ingredients
 

  • cup (300 g) creamy peanut butter
  • ¾ cup (158 g)  butter (vegan or regular), melted
  • 1 cup (200 g) light brown sugar
  • ½ cup (100 g) granulated sugar
  • 2 eggs
  • 1 tbsp vanilla extract
  • ½ tsp salt
  • cup (220 g) all purpose flour
  • cup (80 g) semisweet chocolate chips or chopped chocolate (dairy free or regular), OPTIONAL

Instructions
 

  • Line your 8×8 baking pan with wax paper on all four sides (this helps the peanut butter not stick!). Melt the peanut butter in the microwave or on the stove. Pour the melted peanut butter into the pan and then freeze for one to two hours – you’ll know it’s ready when you can remove the peanut butter in one piece.
  • Once the peanut butter has frozen, preheat the oven to 350°F. Take the frozen baking pan out of the freezer and remove the wax paper with the peanut butter. Line the pan with parchment paper, making sure it is slightly overhanging so you can easily lift the blondies out once cooled. 
  • Melt the butter in a large bowl in the microwave or in a small pan over the stove.
  • Add in both the sugars and use a whisk to whisk the butter and sugars together. Keep whisking until the mixture resembles a paste that pulls away cleanly from the side of the bowl when you mix it.
  • Add the eggs and vanilla and mix again.
  • Pour the flour and salt into the bowl and mix with the whisk until just combined (it should only take about a minute). This is important, because over-mixing at this stage will affect the texture of the blondies!
  • Gently fold in the chocolate chips until just combined.
  • Pour half of the blondie batter into the prepared pan. Peel the peanut butter layer off of the wax paper and place it on top of the blondie batter. 
  • Pour the rest of the blondie batter on top and spread it so it is evenly covering the peanut butter layer. You can sprinkle more chocolate chips or peanut butter chips on top now if you wish!
  • Bake for 25-35 minutes. The top of the blondies should be crinkly and when you insert a toothpick in the middle the toothpick should not come out clean. The blondies are ready when the toothpick has a few wet crumbs, but not wet batter.
  • Let the blondies cool completely before slicing. Enjoy!
