Peanut Butter Fudge Brownies

You ever bite into a brownie and think, “This is good… but it could be more dramatic”? Same. That’s where Peanut Butter Fudge Brownies step in.

We’re talking dense, chocolatey, fudgy goodness with ribbons of creamy peanut butter swirling through every bite. This isn’t the cakey brownie your aunt brings to potlucks. This is the rich, slightly over-the-top, “I need milk immediately” kind of brownie. And honestly? We love that energy.

Let’s make something dangerously good.

Why This Recipe is Awesome

Let me hype this up properly:

• Ultra fudgy texture. None of that dry, crumbly nonsense.
• Peanut butter swirls. Not mixed in. Swirled. There’s a difference.
• Easy ingredients. No weird specialty items.
• Crowd favorite. Chocolate + peanut butter = undefeated combo.
• Next-day perfection. Somehow even better after resting overnight.

These brownies don’t try to be subtle. They’re rich, bold, and unapologetically indulgent. IMO, that’s how brownies should be.

Ingredients You’ll Need

Let’s gather the chocolatey essentials.

For the Brownie Batter:

• 1 cup unsalted butter, melted (liquid gold)
• 1 ¼ cups granulated sugar
• ¾ cup brown sugar (for that deep, fudgy flavor)
• 3 large eggs
• 1 tsp vanilla extract
• ¾ cup unsweetened cocoa powder
• 1 cup all-purpose flour
• ½ tsp salt (essential, not optional)
• ½ tsp baking powder
• ½ cup chocolate chips (because we don’t hold back)

For the Peanut Butter Swirl:

• ¾ cup creamy peanut butter
• 2 tbsp powdered sugar
• 1–2 tbsp milk (just enough to loosen it slightly)

Optional:

• Extra chocolate chips on top
• Flaky sea salt sprinkle

Step-by-Step Instructions

1. Preheat and prep.
   Set your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper. Leave some overhang for easy lifting later.
2. Mix sugars and butter.
   In a large bowl, whisk melted butter with granulated and brown sugar. Mix until glossy and smooth. This step builds that signature crackly top.
3. Add eggs and vanilla.
   Add eggs one at a time, whisking well after each. Stir in vanilla. The batter should look thick and shiny.
4. Add dry ingredients.
   Sift in cocoa powder, flour, salt, and baking powder. Fold gently until just combined. Don’t overmix. We want fudgy, not tough.
5. Fold in chocolate chips.
   Stir them through the batter. Try not to eat half of them straight from the bowl.
6. Prepare peanut butter swirl.
   Mix peanut butter, powdered sugar, and milk until smooth and slightly pourable. Think thick but spreadable.
7. Assemble the magic.
   Pour brownie batter into the prepared pan. Dollop spoonfuls of peanut butter mixture over the top.
8. Swirl like an artist.
   Use a knife or toothpick to create swirls. Don’t overdo it—big ribbons look better than muddy blending.
9. Bake.
   Bake for 28–32 minutes. The center should look slightly underdone but not jiggly. A toothpick should come out with moist crumbs, not wet batter.
10. Cool completely.
    Yes, completely. Warm brownies are amazing—but cutting too early equals crumbly chaos. Let them set.
11. Slice and admire.
    Lift out, cut into squares, sprinkle flaky salt if desired, and prepare for compliments.

Common Mistakes to Avoid

• Overbaking. This is the fastest way to ruin fudgy brownies. Pull them out when slightly underdone in the center.
• Overmixing the batter. Stir until combined, then stop. No marathon mixing sessions.
• Skipping parchment paper. Brownies stick. Don’t fight your pan unnecessarily.
• Using natural peanut butter without stirring it well. Separation is not cute here.
• Over-swirling. You want ribbons, not beige confusion.

Alternatives & Substitutions

• Crunchy peanut butter: Adds texture if you like surprise crunch.
• Dark chocolate chips: Intensifies the chocolate flavor.
• Gluten-free option: Use a 1:1 gluten-free flour blend. Texture stays rich and fudgy.
• Healthier-ish swap: Reduce sugar slightly and add a tablespoon of Greek yogurt for moisture.
• Extra indulgent version: Add a thin layer of chocolate ganache on top once cooled. Because why not?

FYI, chilling the brownies in the fridge for an hour before slicing gives super clean edges. Bakery-level neat.

FAQ (Frequently Asked Questions)

Why are my brownies cakey instead of fudgy?
You probably overbaked them or added too much flour. Measure carefully and watch the oven.

Can I double the recipe?
Absolutely. Use a 9×13 pan and increase baking time slightly. Keep an eye on the center.

Can I freeze these?
Yes! Wrap tightly and freeze for up to 2 months. Thaw at room temperature.

Can I use oil instead of butter?
Technically yes, but butter gives better flavor and that shiny top. Choose wisely.

Why did my peanut butter sink?
If it’s too thin, it can sink into the batter. Keep it thick but spreadable.

How should I store them?
Room temperature in an airtight container for 3–4 days. If your kitchen runs warm, refrigerate.

Can I add nuts?
Of course. Chopped peanuts or walnuts add crunch if that’s your vibe.
