Ingredients:
- For the Brownie Base:
- 1 cup (2 sticks) unsalted butter, melted
- 2 cups granulated sugar
- 1 cup unsweetened cocoa powder
- 1 teaspoon salt
- 1 teaspoon baking powder
- 1 tablespoon vanilla extract
- 4 large eggs
- 1 cup all-purpose flour
- For the Peanut Butter Fudge Swirl:
- 1 cup creamy peanut butter
- 1 cup powdered sugar
- 1/4 cup (4 tablespoons) unsalted butter, softened
- 2 tablespoons milk
- 1/2 teaspoon vanilla extract
- Optional Toppings:
- Chopped peanuts
- Chocolate chips
- Sea salt flakes
Preparing the Brownie Batter
- Melt the Butter: In a large, microwave-safe bowl, melt the 1 cup (2 sticks) of unsalted butter. You can do this in 30-second intervals, stirring in between, to prevent splattering. Alternatively, melt the butter in a saucepan over low heat.
- Combine Wet Ingredients: Once the butter is melted, remove it from the heat and stir in the 2 cups of granulated sugar. Mix well until the sugar is mostly dissolved and the mixture is smooth.
- Add Cocoa Powder and Dry Ingredients: Add the 1 cup of unsweetened cocoa powder, 1 teaspoon of salt, and 1 teaspoon of baking powder to the butter and sugar mixture. Stir until everything is well combined and there are no lumps of cocoa powder remaining. The mixture will be quite thick at this point.
- Incorporate Vanilla and Eggs: Stir in the 1 tablespoon of vanilla extract. Then, add the 4 large eggs one at a time, mixing well after each addition. Make sure each egg is fully incorporated before adding the next. This is crucial for a fudgy texture.
- Add Flour: Gradually add the 1 cup of all-purpose flour to the wet ingredients. Mix until just combined. Be careful not to overmix the batter, as this can lead to tough brownies. A few streaks of flour are okay at this stage.
Making the Peanut Butter Fudge Swirl
- Combine Peanut Butter and Butter: In a separate medium-sized bowl, combine the 1 cup of creamy peanut butter and the 1/4 cup (4 tablespoons) of softened unsalted butter. Make sure the butter is truly softened, not melted, for the best consistency.
- Add Powdered Sugar: Add the 1 cup of powdered sugar to the peanut butter and butter mixture. Mix well until the powdered sugar is mostly incorporated. It will be quite thick and crumbly at this point.
- Incorporate Milk and Vanilla: Add the 2 tablespoons of milk and the 1/2 teaspoon of vanilla extract to the peanut butter mixture. Mix until smooth and creamy. If the mixture is too thick, add a tiny bit more milk, a teaspoon at a time, until you reach the desired consistency. You want it to be easily swirlable.
Assembling and Baking the Brownies
- Prepare the Baking Pan: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan. Alternatively, you can line the pan with parchment paper, leaving an overhang on the sides for easy removal of the brownies after baking.
- Pour Brownie Batter: Pour the brownie batter into the prepared baking pan and spread it evenly with a spatula.
- Dollop Peanut Butter Fudge: Drop spoonfuls of the peanut butter fudge mixture over the top of the brownie batter. Space the dollops evenly across the surface.
- Create the Swirl: Use a knife or skewer to swirl the peanut butter fudge into the brownie batter. Be careful not to over-swirl, as you want to maintain distinct swirls of peanut butter fudge.
- Add Optional Toppings: If desired, sprinkle chopped peanuts, chocolate chips, or sea salt flakes over the top of the brownies.
- Bake the Brownies: Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out with moist crumbs attached. Be careful not to overbake, as this will result in dry brownies.
- Cool Completely: Remove the brownies from the oven and let them cool completely in the pan before cutting. This is important for achieving a clean cut and preventing the brownies from crumbling. Cooling them in the refrigerator will speed up the process and make them even fudgier.
- Cut and Serve: Once the brownies are completely cooled, cut them into squares and serve. Enjoy!
Tips for Perfect Peanut Butter Fudge Brownies
- Use High-Quality Cocoa Powder: The quality of your cocoa powder will significantly impact the flavor of your brownies. Opt for a Dutch-processed cocoa powder for a richer, more intense chocolate flavor.
- Don’t Overmix the Batter: Overmixing the brownie batter can develop the gluten in the flour, resulting in tough brownies. Mix until just combined, and don’t worry about a few streaks of flour.
- Use Room Temperature Eggs: Room temperature eggs emulsify better with the other ingredients, resulting in a smoother batter and a more tender brownie.
- Adjust Baking Time: Baking times may vary depending on your oven. Start checking the brownies at 30 minutes and adjust the baking time as needed.
- Cool Completely Before Cutting: This is the most important tip for achieving clean-cut brownies. Cooling them completely allows the brownies to set and prevents them from crumbling.
- Store Properly: Store leftover brownies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week.
- Make Ahead: You can make the brownie batter and peanut butter fudge swirl ahead of time and store them separately in the refrigerator for up to 24 hours. Bring them to room temperature before assembling and baking.
- Variations: Feel free to experiment with different variations of this recipe. You can add chopped nuts, chocolate chunks, or even a layer of caramel to the brownies.
Troubleshooting
Why are my brownies dry?
Overbaking is the most common cause of dry brownies. Make sure to check the brownies frequently while baking and remove them from the oven when a toothpick inserted into the center comes out with moist crumbs attached. Also, avoid overmixing the batter, as this can also contribute to dry brownies.
Why are my brownies too gooey?
Underbaking can result in brownies that are too gooey. If your brownies are still very wet in the center after the recommended baking time, continue baking them for a few more minutes, checking frequently. Also, make sure your oven is properly calibrated.
Why is my peanut butter swirl sinking into the batter?
If your peanut butter swirl is sinking into the batter, it could be because the peanut butter mixture is too thin. Try adding a little more powdered sugar to the peanut butter mixture to thicken it up. Also, be careful not to over-swirl the peanut butter into the brownie batter.
Can I use natural peanut butter?
While you can use natural peanut butter, keep in mind that it may affect the consistency of the peanut butter fudge swirl. Natural peanut butter tends to be oilier than processed peanut butter, so you may need to adjust the amount of milk you add to the peanut butter mixture. You may also need to stir the natural peanut butter very well before using it to ensure it’s properly combined.
Can I make these brownies gluten-free?
Yes, you can make these brownies gluten-free by substituting the all-purpose flour with a gluten-free all-purpose flour blend. Make sure to choose a blend that is designed for baking and contains xanthan gum, which helps to bind the ingredients together. You may also need to adjust the baking time slightly.
