Peanut Butter Swirl Brownies for Two: From Prep to Plate

Now that you have everything you need, let’s get started on making these delectable brownies!
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your brownies bake evenly and come out perfectly fudgy.
Step 2: Prepare the Loaf Pan
Line your 9×5-inch loaf pan with parchment paper, leaving a bit of an overhang on the sides. This will make it easy to lift the brownies out once they’re baked.
Step 3: Mix the Brownie Batter
In a mixing bowl, combine the melted butter and granulated sugar. Whisk together until well combined. Next, add the egg and vanilla extract, mixing until smooth.
Step 4: Add Dry Ingredients
Sift in the cocoa powder, flour, baking powder, and salt. Gently fold the dry ingredients into the wet mixture until just combined. Be careful not to overmix; a few lumps are perfectly fine!
Step 5: Prepare the Peanut Butter Swirl
In a separate bowl, combine the melted butter, powdered sugar, smooth peanut butter, vanilla extract, and pinch of salt. Mix until smooth and creamy.
Step 6: Layer the Batter
Pour half of the brownie batter into the prepared loaf pan, spreading it evenly. Then, dollop spoonfuls of the peanut butter mixture over the batter. Use a knife or toothpick to swirl the peanut butter into the brownie batter gently.
Step 7: Finish with Brownie Batter
Pour the remaining brownie batter over the peanut butter layer, smoothing it out. Add a few more dollops of the peanut butter mixture on top and swirl again for a beautiful marbled effect.
Step 8: Bake
Bake in the preheated oven for about 20-25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Be careful not to overbake; you want them to stay fudgy.
Step 9: Cool and Serve
Once baked, remove the brownies from the oven and let them cool in the pan for 10 minutes. Then, lift them out using the parchment paper overhang and transfer them to a wire rack to cool completely. Slice and enjoy your Peanut Butter Swirl Brownies for Two!

Troubleshooting Tips
If you encounter any issues while baking your Peanut Butter Swirl Brownies for Two, here are some helpful tips:
- If your brownies are too dry, you may have overbaked them. Keep an eye on the timer!
- If the batter is too thick, add a splash of milk to loosen it up.
- For a more pronounced peanut butter flavor, increase the amount of peanut butter in the swirl.
- If you find the brownies too sweet, consider reducing the sugar slightly in the brownie batter.
Shelf Life & Storage
To keep your Peanut Butter Swirl Brownies fresh and delicious:
- Store them in an airtight container at room temperature for up to 3 days.
- For longer storage, refrigerate them for up to a week.
- These brownies can also be frozen. Wrap them individually in plastic wrap and place them in a freezer-safe container for up to 3 months.
Troubleshooting Q&A
What if my brownies are too cakey?
If your brownies turned out too cakey, you may have added too much flour or overmixed the batter. Make sure to measure carefully and mix just until combined.
Can I use crunchy peanut butter instead of smooth?
Absolutely! Crunchy peanut butter will add a delightful texture to your brownies, making them even more interesting.
Why are my brownies not rising?
If your brownies didn’t rise, check if your baking powder is fresh and that you added the correct amount. Also, ensure you’re not overmixing, which can deflate the batter.
How can I make these brownies gluten-free?
To make these brownies gluten-free, simply substitute all-purpose flour with a gluten-free flour blend. Just be sure it’s a blend designed for baking!
