Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the Brownie Base:

  • Unsalted butter
  • Semi-sweet chocolate chips
  • Granulated sugar
  • Brown sugar
  • Eggs
  • Vanilla extract
  • All-purpose flour
  • Cocoa powder
  • Baking powder
  • Salt

For the Peanut Butter Swirl:

  • Creamy peanut butter
  • Powdered sugar
  • Vanilla extract
  • Milk (as needed for consistency)

Directions

  1. Preheat the Oven: Set your oven to 350°F (175°C). Grease and line an 8×8-inch baking pan with parchment paper.
  2. Melt the Chocolate and Butter: In a microwave-safe bowl, melt butter and chocolate chips in 30-second intervals, stirring until smooth. Let cool slightly.
  3. Mix the Brownie Batter: In a large bowl, whisk together the granulated sugar, brown sugar, eggs, and vanilla extract. Stir in the melted chocolate mixture.
  4. Combine Dry Ingredients: In another bowl, whisk together flour, cocoa powder, baking powder, and salt. Gradually fold this into the wet mixture until just combined.
  5. Prepare the Peanut Butter Swirl: In a separate bowl, mix peanut butter, powdered sugar, vanilla extract, and a little milk until smooth and spreadable.
  6. Assemble the Brownies: Pour half of the brownie batter into the prepared pan. Drop spoonfuls of the peanut butter mixture on top, then pour the remaining brownie batter over it. Swirl with a knife to create a marbled effect.
  7. Bake: Bake for 30-35 minutes or until a toothpick inserted in the center comes out with a few moist crumbs.
  8. Cool and Serve: Let the brownies cool completely before slicing. Enjoy!

FAQs

Can I use natural peanut butter?

Yes, but make sure to stir it well to prevent separation, as natural peanut butter tends to be more oily.

How do I make these brownies extra fudgy?

Use less flour and slightly underbake them to maintain a gooey center.

Can I double the recipe?

Yes! Use a 9×13-inch pan and increase the baking time by about 10 minutes.

Can I use a boxed brownie mix?

Absolutely! Prepare the mix as directed and simply add the peanut butter swirl for a quick upgrade.

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

Use a sharp knife dipped in hot water, wiping it clean between each cut.

Can I make these brownies dairy-free?

Yes! Substitute butter with a dairy-free alternative and use dairy-free chocolate chips.

Can I add nuts to the batter?

Of course! Chopped peanuts or walnuts add a great crunch to these brownies.

Why did my brownies turn out dry?

Overbaking is the most common cause. Remove them from the oven when the center is slightly underdone.

Can I add caramel to this recipe?

Yes! Drizzle caramel sauce over the peanut butter swirl before baking for an extra indulgent treat.

How do I store leftover brownies to keep them fresh?

Wrap them tightly in plastic wrap or place them in an airtight container to maintain freshness.
