Equipment
8×8-inch baking dish
Ingredients
1 cup (227g) unsalted butter
1 cup (175g) semisweet chocolate chips, divided
1¼ cups (150g) all-purpose flour
½ cup (50g) unsweetened cocoa powder
1 teaspoon salt
1 cup (200g) granulated sugar
1 cup (220g) firmly packed light brown sugar
3 large eggs
1 tablespoon vanilla extract
½ cup creamy peanut butter
Instructions
Preheat your oven to 350°F (177°C). Spray an 8×8-inch square baking pan with nonstick baking spray and line it with parchment paper for easy removal.
In a small saucepan, melt the butter over medium heat. Remove from heat and whisk in ½ cup of chocolate chips until melted and smooth. Transfer the mixture to a large bowl and allow it to cool slightly. Alternatively, you can melt the butter in a microwave-safe bowl and stir in the chocolate chips until smooth.
In another bowl, sift together the flour and cocoa powder, then whisk in the salt. This step ensures that your dry ingredients are light and lump-free.
To the melted chocolate mixture, whisk in the granulated sugar, brown sugar, eggs, and vanilla extract until smooth and glossy. Fold in the sifted dry ingredients until well combined, being careful not to over-mix. Gently fold in the remaining ½ cup of chocolate chips.
Pour the brownie batter into the prepared pan and use a spatula to spread it evenly to the edges. Drop the peanut butter over the top of the batter by teaspoonfuls, then use the tip of a knife or a skewer to swirl it gently into the batter for a marbled effect.
Bake for 40 to 45 minutes or until the center no longer wobbles when gently shaken. For a super fudgy texture, bake for about 35 minutes. If the peanut butter begins to brown, cover the pan loosely with foil after 25 minutes of baking. Note that covering the brownies may increase baking time by 5 to 10 minutes.
Allow the brownies to cool completely in the pan before slicing. This will help them set and give you clean, even squares.
Notes
Bring your eggs to room temperature before baking, as they will mix more easily and evenly into the batter. You can place cold eggs in a bowl of warm water for a few minutes to speed up the process.
For accurate measurements, use a kitchen scale. If you don’t have one, fluff your flour before spooning it into your measuring cup and leveling it off with a knife to avoid adding too much flour.
Avoid over-mixing the batter to keep your brownies soft and fudgy rather than tough. Use a spatula instead of a mixer.
When cutting the brownies, wipe your knife with a damp cloth or run it under warm water between slices for clean edges.
When melting the chocolate, ensure no water comes into contact with it, as even a small amount can cause the chocolate to seize.
Sifting the dry ingredients helps aerate the flour and cocoa powder and prevents dense or heavy brownies.
When swirling the peanut butter, use a light hand. Over-swirl and the peanut butter will blend into the batter instead of creating distinct ribbons.

FAQs
1. Can I use natural peanut butter instead of creamy peanut butter?
It’s best to use regular creamy peanut butter for this recipe, as natural peanut butter tends to separate and has a runnier texture, which can affect the swirl pattern and baking consistency. If you prefer using natural peanut butter, make sure it’s well-stirred and thick enough to hold shape when dropped onto the batter.
2. How can I make the brownies extra fudgy?
For extra fudgy brownies, bake them for about 35 minutes instead of the full time. The center should still be slightly soft but not raw. Avoid over-baking, as it will lead to a cakier texture. You can also reduce the flour slightly (by about 2 tablespoons) for an even denser result.
3. Can I double the recipe?
Yes, you can easily double the recipe and bake it in a 9×13-inch pan. The baking time will be a bit longer—around 45 to 50 minutes. Check the center for doneness using the same method: it should no longer wobble when gently shaken.
4. How should I store these brownies?
Store the brownies in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 1 week. For longer storage, wrap them tightly in plastic wrap and freeze for up to 3 months. Thaw at room temperature before serving.
5. Can I add other mix-ins to the batter?
Absolutely. You can add chopped nuts, extra chocolate chunks, or even swirl in a bit of caramel or Nutella for a fun twist. Just be careful not to overload the batter with too many additions, as it may affect baking time and texture.
