Ingredients You’ll Need

Here’s what you’ll need for these brownies, and trust me, every single ingredient plays a starring role. From the intense cocoa to the creamy swirl of peanut butter, each component builds the perfect balance of flavors and textures that make these Peanut Butter Chocolate Fudge Brownies unforgettable.

Unsalted butter (1/2 cup, melted): Gives the brownies a tender crumb and that classic fudgy richness.
Granulated sugar (1 cup): Sweetens the brownies and helps create that shiny, crackled top.
Large eggs (2): Bind everything together for a chewy, moist interior.
Vanilla extract (1 teaspoon): Adds warmth and complexity to both chocolate and peanut butter flavors.
Unsweetened cocoa powder (1/3 cup): Provides deep chocolate flavor without any added sweetness.
All-purpose flour (1/2 cup): Just enough to give body to the brownies while keeping them moist and dense.
Salt (1/4 teaspoon): Balances the sweetness and intensifies the flavors.
Baking powder (1/4 teaspoon): Lifts the brownies just slightly for a bit of lightness.
Semi-sweet chocolate chips (1/2 cup): Melt into little pockets for extra chocolate gooeyness.
Creamy peanut butter (1/2 cup): Swirled in for that classic nutty goodness and beautiful marbled look.
Sweetened condensed milk (1/4 cup): Blends with the peanut butter to create a rich, creamy swirl that bakes up like a dream.

How to Make Peanut Butter Chocolate Fudge Brownies

Step 1: Prep Your Pan and Oven

Start by preheating your oven to 350°F (175°C); this way, your brownies will bake evenly from edge to center. Line an 8×8-inch baking pan with parchment paper, making sure the sides hang over so you can lift out the brownies later with zero fuss. This nonstick barrier is a lifesaver for fudgy desserts like these!

Step 2: Combine Wet Ingredients

In a large bowl, whisk together the melted butter and sugar until the mixture looks glossy and unified. This step helps dissolve the sugar a bit, creating a shiny top. Next, add the eggs and vanilla extract, beating the mixture until it’s smooth and just a little bit frothy—this brings chew and structure to your Peanut Butter Chocolate Fudge Brownies.

Step 3: Add Dry Ingredients

Sift or gently stir in the cocoa powder, all-purpose flour, salt, and baking powder. Mixing these in just until combined is key—overbeating brownie batter can make them tough rather than tender and fudge-like. Once the mixture is thick and even, stop stirring and switch to a spatula for the final fold.

Step 4: Fold in Chocolate Chips

Now comes the chocolate chip magic. Gently fold in the semi-sweet chocolate chips so they’re evenly distributed. These chips melt into chocolatey pools during baking, creating rich bites throughout the finished brownies.

Step 5: Prepare the Peanut Butter Swirl

In a separate small bowl, stir together the creamy peanut butter and sweetened condensed milk until smooth and glossy. The condensed milk transforms the peanut butter into a swirlable, ultra-creamy mixture that won’t dry out during baking—it’s what gives these brownies their swoon-worthy marbled effect.

Step 6: Assemble and Swirl

Pour the brownie batter into your lined pan, smoothing the top as you go. Drop spoonfuls of the peanut butter mixture evenly over the surface. Using a butter knife or a skewer, swirl the peanut butter and chocolate batters together in looping motions, making sure not to overdo it—distinct swirls look and taste best!

Step 7: Bake and Cool

Bake your Peanut Butter Chocolate Fudge Brownies in the center of your oven for 25 to 30 minutes. You’re looking for set edges and a center that still looks slightly underdone; a toothpick should come out with moist crumbs, not wet batter. Cool completely in the pan to firm up the fudge factor, then lift and slice into perfect squares.

How to Serve Peanut Butter Chocolate Fudge Brownies

Garnishes

The peanut butter-chocolate combo truly shines on its own, but if you want to dress things up, try a dusting of powdered sugar, a handful of chopped roasted peanuts, or a drizzle of extra melted chocolate over the top. These simple touches let everyone know this isn’t just any brownie—it’s a showstopping treat!

Side Dishes

Peanut Butter Chocolate Fudge Brownies are rich, so pair them with something cool and refreshing. A scoop of vanilla ice cream makes every bite creamier, while a tumbler of cold milk or a bold cup of coffee perfectly balances the sweetness and chocolatey intensity. For party platters, add fresh strawberries or slices of banana on the side.

Creative Ways to Present

Want to go beyond the classic square? Try cutting the brownies into heart or star shapes for special occasions, or serve them parfait-style by layering chunks of brownie, ice cream, and whipped cream in a glass. For parties, skewer small brownie bites onto sticks for easy-to-eat treats that look irresistible.

Make Ahead and Storage

Storing Leftovers

Once your Peanut Butter Chocolate Fudge Brownies have cooled, pop them into an airtight container. They’ll stay fresh and fudgy for up to four days at room temperature. If your kitchen runs warm, refrigerate to avoid melting chocolate swirls; just let them come closer to room temp before serving for the best texture.

Freezing

Have leftovers or prepping ahead? No problem! Wrap individual brownies tightly in plastic wrap and slide them into a freezer bag. They’ll keep their incredible texture and flavor for up to two months. When cravings strike, just thaw them at room temperature or heat briefly in the microwave for gooey goodness.

Reheating

If you love warm, melty brownies, pop a square in the microwave for about 10 to 15 seconds. This brings back that just-baked softness and makes the chocolate chips extra melty. Watch closely—they heat up fast! Top with a scoop of ice cream for heavenly results.

FAQs

Can I use crunchy peanut butter instead of creamy?

Absolutely! Crunchy peanut butter adds delightful bits of roasted peanut throughout your Peanut Butter Chocolate Fudge Brownies, making each bite a little more textured and nutty.

How do I know when the brownies are done baking?

Look for set edges and a center that appears slightly underbaked—that’s what keeps them fudgy. A toothpick inserted near the middle should come out with a few moist crumbs attached, but no wet batter.

Can I double the recipe for a larger batch?

Yes, you can! Simply double every ingredient and bake in a 9×13-inch pan. Keep an eye on baking time; check for doneness around 30 to 35 minutes since the larger pan might need a little extra time.

Are these brownies suitable for gluten-free diets?

To make gluten-free Peanut Butter Chocolate Fudge Brownies, substitute a one-to-one gluten-free flour blend for the all-purpose flour. Be sure your baking powder and chocolate chips are certified gluten-free, too!

What can I use if I don’t have sweetened condensed milk?

The creamy swirl owes a lot to condensed milk, but you can try substituting with a thick vanilla yogurt or a blend of heavy cream and a bit of sugar in a pinch. The texture will be a little different but still delicious.

Final Thoughts

These Peanut Butter Chocolate Fudge Brownies are the kind of dessert that magically transforms any day into a special occasion. They’re easy enough for a weeknight treat, but impressive enough for sharing (if you’re feeling generous).
