Peanut Butter-Swirled Fudgy Brownies

I’ve been making lots of peanut butter recipes recently. Even more so than usual.

But I doubt you’re complaining.

I’m on vacation and make things that I know will turn out and that we like. This isn’t the time I want to experiment.

And I’ll never say no to peanut butter and chocolate, especially by way of dense, fudgy, rich, one-bowl brownies.

I have three main brownie base recipes on my site, that all others are derived from.

They’re each one-bowl, no-mixer recipes, that you can make in less than 5 minutes. As fast as using a boxed mix and they include:

Three eggs with melted chocolate in a 9×9 pan

Two eggs with cocoa powder in a 8×8 pan

I went for option two because the smaller the batch size, the better. I’m getting into a swimsuit daily.

Also, I tend not to keep chocolate bars on hand here in Aruba because they melt, whereas I always have cocoa powder stashed.

I melted the butter in the micro, whisked in the rest of the ingredients, and since I didn’t want to be bothered with having to frost them after baking, I swirled in peanut butter before baking.

I’m a big fan of peanut butter swirls and swirls in general. They’re a time-saver and they taste good. A win-win.

There are two major turnoffs for me with brownies, cakey and dry, and these are neither. They’re thick, dense, rich, ultra-fudgy, with zero traces of cakiness nor dryness.

Although cocoa powder sometimes gets a bad rap compared to melted chocolate, thousands of people love these cocoa powder brownies as I wrote about. You’ll change your mind about cocoa powder after trying them.

They’re not too sweet, very chocolaty, and I amp the chocolate intensity with a splash of coffee and espresso granules to bring out and enhance the chocolatiness, but they don’t make the brownies taste like coffee.

The peanut butter adds a touch of saltiness and balances the chocolate intensity.

And everything is better with peanut butter.

Peanut Butter-Swirled Fudgy Brownies

By Averie Sunshine
These one-bowl, no-mixer brownies are thick, dense, rich, ultra-fudgy, with zero traces of cakiness nor dryness. Stir the batter together faster than you can open a boxed mix. The peanut butter swirls add a touch of saltiness, balance the chocolate intensity, and everything is better with peanut butter. Plus, it saves you from having to frost them later. If youโ€™ve never tried cocoa powder-based brownies or think theyโ€™re somehow inferior to melted chocolate, these brownies will change your mind.

Ingredients 

  • 10 tablespoons unsalted butter, 1 1/4 sticks, melted
  • 2 large eggs
  • 1 cup granulated sugar
  • ยผ cup light brown sugar, packed
  • 2 tablespoons brewed coffee, leftover from the morning brew is fine, optional but recommend to enhance chocolate flavor and does not make brownies taste like coffee
  • 1 cup granulated sugar
  • ยผ cup light brown sugar, packed
  • 2 tablespoons brewed coffee, leftover from the morning brew is fine, optional but recommend to enhance chocolate flavor and does not make brownies taste like coffee
  • 1 teaspoon vanilla extract
  • ยพ cups plus 2 tablespoons unsweetened cocoa powder (natural or Dutch-process, I used Hersheyโ€™s natural
  • 1 teaspoon instant espresso granules, optional but recommend to enhance chocolate flavor and does not make brownies taste like coffee
  • ยผ teaspoon salt, optional and to taste
  • ยฝ cup all-purpose flour
  • ยผ cup creamy peanut butter, melted

Instructions 

  • Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil leaving overhang on the sides, spray with cooking spray; set aside.
  • In a large, microwave-safe bowl, add the butter and heat on high power to melt, about 1 minute. Allow butter to cool momentarily so you donโ€™t scramble the eggs.
  • Add the eggs, sugars, optional coffee, vanilla, and whisk to combine.
  • Add the cocoa powder, optional espresso granules, optional salt, and whisk to combine. If your cocoa powder is lumpy, it could take a couple minutes of vigorous whisking.
  • Add the flour and stir until just combined, donโ€™t overmix.
  • Turn batter out into prepared pan; set aside.
  • In a small microwave-safe bowl, add the peanut butter and heat on high power to melt, about 45 seconds.
  • Drizzle peanut butter over batter to create swirls. To create the marbled pattern shown, drizzle peanut butter over batter in 5 wide, evenly spaced, parallel lines, each spanning the length of the pan. Like 5 rows of long train tracks. Rotate pan 90-degrees. With a toothpick, starting at the top of the pan, โ€œdrawโ€ 4 or 5 evenly spaced lines through the peanut butter. Youโ€™re dragging the toothpick perpendicularly through the first set of lines to create the marbling.
  • Bake for about 20 to 25 minutes, or until done; donโ€™t overbake. A toothpick inserted in the center should come out mostly clean, or with a few moist crumbs, but no batter. Allow brownies to cool in pan for about 1 hour before lifting out with foil overhang and slicing.
  • Brownies will keep airtight at room temperature or refrigerator for up to 1 week, or in the freezer for up to 6 months. I prefer to store them in the fridge and serve them slightly chilled.

  1. These were so good! I love that the brownies have a really intense chocolate flavor and aren’t overly sugary-sweet. This will definitely be one of my go-to desserts. Thanks!

  2. These look so tasty! I will definitely make them once the weather isn’t so hot out. Chocolate and peanut butter are always a winning combination! :)

  3. These look wonderful! Went out & bought some cocoa powder & realized I don’t see a baking temperature. Hate to assume things… could it be the good’ol default temp of 350? Thanks

    1. Gah! Sorry about that! Yes – 350F. I updated the post. Not sure how I managed to omit that when I copy/pasted much of the recipe from my own recipe that I adapted it from. But that’s what happens when I have chocolate on the brain :)

      Enjoy the brownies & LMK how you like them!

      1. I used just “half” of your recipe cause I added cheese and blackberries. I baked at 170C (about 340F). It turned out delicious. Thanks

      2. cheese, blackberries, peanut butter, and brownies – that’s such a unique combo of flavors for brownies! Glad you enjoyed them!

  4. I love the peanut butter swirls on top Averie – these brownies look just incredible! Pinned :)

  5. I love chocolate and peanut butter together. I’m not usually a fan of cocoa powder brownies, but if you say they’re awesome, I’ll give them a try. Also, please tell me you didn’t cut out little squares of parchment for your photos. You’re supposed to be on vacation. :)

    1. Yes, I did. Or else they would literally turn into a melted fudge puddle all over my table but such is life :) I lived.

      And I never!!! thought that cocoa powder could stand a chance to melted choc in brownies but this recipe (adpated from Alice Medrich) made a believer out of me!

  6. Oh my, Averie! These brownies are the best! You’ve really outdone yourself here. And that mile-high stack there? Yeah, that needs to get in front of me!

  7. Yum, yum! These brownies look perfect and you can’t beat chocolate with peanut butter in my opinion.
