Ingredients You’ll Need

Let’s keep things simple but spectacular. Each ingredient for Peanut Butter Stuffed Brownies brings its own flair, making every bite an epic moment of chocolate and peanut butter harmony. Here’s what you’ll need, along with why it matters:

  • Unsalted Butter: The base of our brownies, giving them richness and that irresistible fudgy bite.
  • Granulated Sugar: Sweetens the batter and creates those signature crackly tops.
  • Large Eggs: Bind everything together and add a tender structure.
  • Vanilla Extract: A splash for warmth and aromatic depth, making the chocolate flavors shine!
  • Unsweetened Cocoa Powder: Delivers intense chocolate flavor—be generous with quality here.
  • Salt: Balances sweetness and enhances all the other flavors.
  • Baking Powder: Just a little for gentle lift, so your brownies aren’t too dense.
  • All-Purpose Flour: Provides structure without making the brownies cakey.
  • Semi-Sweet Chocolate Chips: For melty pockets of chocolate in every slice; don’t skip them!
  • Creamy Peanut Butter: The star of the show, creating that rich, dreamy layer inside.
  • Powdered Sugar: Thickens and sweetens the peanut butter for a luscious, creamy bite.

How to Make Peanut Butter Stuffed Brownies

Step 1: Prep Your Pan and Oven

Start by preheating your oven to 350°F (175°C) so it’s perfectly hot when your batter is ready. Line a 9×13-inch baking pan with parchment paper and give it a quick greasing. This step ensures your Peanut Butter Stuffed Brownies release easily and have cleaner edges when slicing.

Step 2: Melt and Mix the Brownie Batter

In a large saucepan over medium heat, gently melt the butter—watch it closely so it doesn’t brown. Remove the pan from heat, stir in your granulated sugar until well blended, then add the eggs one at a time, beating after each addition. Mix in the vanilla for extra flavor. Stir in cocoa powder, salt, and baking powder until the mixture’s smooth and glossy. Fold in the flour, followed by the chocolate chips for irresistible gooeyness in every bite.

Step 3: Make the Peanut Butter Filling

In a small bowl, beat together the creamy peanut butter and powdered sugar until it’s smooth, thick, and spreadable. This sweetened peanut butter filling is what transforms your brownies into Peanut Butter Stuffed Brownies magic!

Step 4: Layer and Assemble the Brownies

Spread half the chocolate batter evenly in your prepared baking pan, making sure it reaches the edges. Drop spoonfuls of the peanut butter filling all over the chocolate base, then gently spread it for a thick, even layer (go slow here, so the chocolate and peanut butter don’t totally mix). Spoon the remaining brownie batter on top and carefully smooth it out to cover the peanut butter completely.

Step 5: Bake to Fudgy Perfection

Slide the pan into your preheated oven and bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs. Resist overbaking—slightly underbaked means ultra-fudgy Peanut Butter Stuffed Brownies! Let them cool completely so the layers set before slicing into decadent squares.

Garnishes

Dust with extra powdered sugar, a drizzle of melted chocolate, or a few crushed peanuts for texture. For a playful twist, swirl a bit of peanut butter across the top before baking—picture-perfect and mouthwatering!

Side Dishes

Pair your Peanut Butter Stuffed Brownies with scoops of vanilla ice cream, fresh strawberries, or a tall glass of icy milk. These sides elevate the chocolate-peanut butter experience and keep every bite fresh and exciting.

Creative Ways to Present

Go bold: Layer the brownie squares in a fancy dessert glass with whipped cream, or cut them with a cookie cutter for custom shapes. Wrap individual brownies in parchment and tie with string for charming lunchbox or party favors. Peanut Butter Stuffed Brownies are an invitation to get creative!

Make Ahead and Storage

Storing Leftovers

Keep your brownies covered in an airtight container at room temperature for up to 4 days. If you want them extra chewy, store them in the fridge—just allow a few minutes at room temperature before enjoying.

Freezing

Peanut Butter Stuffed Brownies freeze beautifully! Wrap each square individually in plastic wrap, then store in a freezer-safe bag or container for up to 2 months. Thaw overnight in the fridge or on the counter for a convenient treat.

Reheating

For the “just-baked” experience, warm a brownie square in the microwave for 10–15 seconds. The peanut butter layer softens, the chocolate chips turn gooey, and every bite tastes like heaven!

FAQs

Can I use crunchy peanut butter instead of creamy?

Definitely! Crunchy peanut butter adds a fantastic texture and a bit of extra peanutty flair. Just be aware that the swirl will be less silky, but still just as tasty.

Why do my brownies seem underbaked in the middle?

That slightly gooey center is intentional—it’s what makes these Peanut Butter Stuffed Brownies so luscious! If the edges are set and the middle is just a little soft, you’ve hit the sweet spot. They’ll firm as they cool.

Can I halve this recipe?

Yes, absolutely. Simply use an 8×8-inch pan and watch the baking time—it may be a little shorter. You’ll have fewer brownies, but all the flavor packed in every bite.

What’s the best way to get clean brownie slices?

Let the brownies cool completely, then use a sharp knife wiped clean between each cut. For ultra-clean slices, refrigerate the brownies before cutting—it really helps keep the peanut butter and chocolate layers neat.

Can I add other mix-ins?

Of course! Chopped nuts, mini peanut butter cups, or white chocolate chips make delicious additions. The joy of Peanut Butter Stuffed Brownies is how easily you can customize them to your cravings.

Final Thoughts

You’re just one bake away from the kind of treat that friends and family will beg you to make again and again. Don’t wait to experience the pure joy of Peanut Butter Stuffed Brownies—they’re easy, decadent, and guaranteed to be the most popular dessert at any gathering. Go on, preheat that oven and treat yourself!
