What sets these brownies apart is the addition of a luscious peanut butter layer. After the brownies have cooled, a generous layer of creamy peanut butter mixed with a touch of powdered sugar and vanilla extract is swirled on top, adding a nutty, sweet contrast to the chocolatey base. The combination of rich chocolate and the nutty creaminess of peanut butter creates a harmonious flavor profile that's hard to resist.

To complete this sweet masterpiece, a marshmallow and cocoa frosting is generously spread over the peanut butter layer, resulting in a triple-layered, visually appealing dessert. The frosting not only adds a delightful sweetness but also gives these brownies their signature look.

For the Brownies:

  • â…“ cup/30 grams unsweetened cocoa powder
  • 2 cups/400 grams granulated sugar
  • 1½ cups/190 grams all-purpose flour
  • ½ teaspoon kosher salt
  • 4 large eggs
  • 1 teaspoon pure vanilla extract

For the Peanut Butter Swirl:

  • 1 (16-ounce/455 gram) jar creamy peanut butter
  • 1/3 cup powdered sugar
  • 1 teaspoon vanilla extract

For the Frosting:

  • ½ cup/115 grams unsalted butter (1 stick)
  • 10 large marshmallows (about 65 grams)
  • 4 cups/500 grams confectioners’ sugar
  • 1/3 cup/80 milliliters whole milk
  • ÂĽ cup/25 grams unsweetened cocoa powder

Method Instructions

  1. Heat the oven to 350 degrees. Coat a 9-by-13-inch pan lightly with cooking spray and line it with parchment paper, leaving a 2-inch overhang on the two long sides.
  2. In a small saucepan, heat the butter and cocoa over low heat until the butter melts, about 5 minutes. Whisk to combine then set aside to cool, 5 minutes.
  3. In a stand mixer fitted with the paddle attachment, combine the granulated sugar, flour, and salt. Add the butter mixture and beat on medium speed until well blended, 1 to 2 minutes. Add the eggs one by one, incorporating each before adding the next, then add the vanilla and mix until combined.
  4. Spread the mixture evenly in the prepared pan. Bake until a tester inserted into the center comes out with a few moist crumbs, 20 to 25 minutes.
  5. Let the brownies cool completely, about 30 minutes.
  6. While the brownies are cooling, prepare the peanut butter swirl. In a bowl, combine the creamy peanut butter, powdered sugar, and vanilla extract. Mix until smooth. Dollop spoonfuls of the peanut butter mixture onto the cooled brownies.
  7. In a medium saucepan, melt the butter and marshmallows over medium heat, stirring often, until both are melted and no lumps remain, about 5 minutes. Add the confectioners’ sugar, milk, and cocoa, and whisk until smooth, about 2 minutes.
  8. Spread the frosting over the brownies with the peanut butter swirl and freeze for 30 minutes.
  9. Remove the brownies from the pan: First, cut the brownies away from the pan edge on both short sides, then lift them out using the parchment paper handles.
  10. After spreading the frosting over the brownies, take a toothpick or a butter knife and gently swirl the peanut butter dollops into the frosting to create a marbled effect.
  11. Enjoy your Peanut Butter Swirl Brownies!

To serve Joanna Gaines' Peanut Butter Brownies, follow these steps:

  • Chill: After making the brownies and adding the peanut butter and frosting layers, allow the brownies to chill in the freezer for at least 30 minutes. This will help set the layers and make it easier to cut into neat squares.
  • Cut into Squares: Once the brownies have properly chilled, use a sharp knife to cut them into squares. You can aim for traditional brownie-sized squares or adjust the size to your preference.
  • Presentation: Arrange the cut brownie squares on a serving platter or individual dessert plates. The peanut butter swirl and frosting will give the brownies an attractive marbled appearance.
  • Optional Garnish: You can enhance the presentation by adding a few optional garnishes. Consider sprinkling some cocoa powder, powdered sugar, or chopped peanuts on top of the brownies for added texture and visual appeal.
  • Serve: Serve these delicious Peanut Butter Brownies as a dessert or sweet treat. They pair wonderfully with a glass of cold milk, a scoop of vanilla ice cream, or a dollop of whipped cream, enhancing the overall indulgence.


  1. Use Good-Quality Ingredients: Since there are relatively few ingredients in this recipe, the quality of each one can significantly impact the final taste. Use high-quality cocoa powder, butter, and peanut butter for the best results.
  2. Properly Line the Pan: When lining your baking pan with parchment paper, leave an overhang on the two long sides. This makes it easier to lift the brownies out of the pan for cutting.
  3. Even Layer: When spreading the brownie batter in the pan, ensure it's evenly distributed. This will result in uniformly baked brownies.
  4. Don't Overbake: Be cautious not to overbake the brownies. They are done when a tester inserted into the center comes out with a few moist crumbs. Overbaking can lead to dry brownies.
  5. Chill for Clean Cuts: After adding the peanut butter swirl and frosting, make sure to chill the brownies in the freezer. This step helps set the layers and makes cutting cleaner and easier.
  6. Marble Effect: When creating the marble effect with the peanut butter swirl and frosting, feel free to get creative. You can create swirls, zigzags, or any pattern you like for an appealing appearance.
  7. Optional Toppings: While the recipe doesn't call for it, consider adding toppings like chocolate chips, chopped nuts, or a drizzle of melted chocolate to further customize your brownies.
  8. Serving Suggestions: These brownies are rich and indulgent. They're best served in small to moderate-sized squares. Pair them with a scoop of vanilla ice cream or a cold glass of milk for a delightful treat.
  9. Storage: Store any leftovers in an airtight container in the refrigerator to maintain their freshness. These brownies can be enjoyed for several days.
  10. Experiment: Feel free to get creative with the recipe. You can add other ingredients like chopped Reese's peanut butter cups or caramel sauce for a unique twist.

Ingredient Substitutes
