Ingredients
These brownies are made with simple ingredients that come together to create the ultimate dessert. Here’s what you’ll need:
- 1/2 cup unsalted butter, melted
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/3 cup unsweetened cocoa powder
- 1/2 cup all-purpose flour
- 1/4 teaspoon salt
- 1/4 teaspoon baking powder
- 1/3 cup peanut butter (creamy or crunchy, your choice!)
Instructions
Now comes the fun part—bringing all these delicious ingredients together to create the perfect peanut butter brownies. Follow these steps for the best results:
- Preheat & Prep:
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease it to prevent sticking. - Mix the Batter:
In a medium bowl, whisk together the melted butter and sugar until smooth. Add in the eggs and vanilla extract, stirring until fully incorporated. - Combine the Dry Ingredients:
In a separate bowl, whisk together the cocoa powder, flour, salt, and baking powder. Gradually add this dry mixture to the wet ingredients, stirring just until combined. Be careful not to overmix—this keeps the brownies nice and fudgy! - Swirl in the Peanut Butter:
Pour the brownie batter into the prepared pan, spreading it evenly. Warm the peanut butter slightly in the microwave for 10–15 seconds so it’s easier to drizzle. Drop spoonfuls of peanut butter on top of the batter and use a knife or toothpick to swirl it through for a marbled effect. - Bake:
Place the pan in the oven and bake for 20–25 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs. Don’t overbake—brownies continue to set as they cool. - Cool & Serve:
Let the brownies cool in the pan for at least 15 minutes before slicing. This helps them firm up and makes for cleaner cuts. Then, dig in and enjoy!
Tweaks and Additions
Want to take your peanut butter brownies to the next level? Here are some fun variations and add-ins to try:
- Extra Chocolate Boost:
Stir in 1/2 cup of chocolate chips into the batter for an even more indulgent chocolate experience. The chocolate chips will melt slightly, creating gooey pockets of extra chocolate that make every bite even more irresistible. - Nutty Crunch:
Add chopped peanuts or walnuts to the batter for extra texture and a satisfying crunch. The nuts add a delightful contrast to the soft, fudgy brownies and enhance the peanut butter flavor. - Salted Caramel Swirl:
Drizzle some caramel sauce over the top along with the peanut butter for a sweet and salty twist. The caramel adds a buttery richness that pairs beautifully with the peanut butter swirls. - Espresso Infusion:
Add 1 teaspoon of instant espresso powder to the batter to intensify the chocolate flavor. Espresso deepens the richness of the brownies without making them taste like coffee—it just brings out the best in the chocolate. - Brownie Sundae:
Serve warm brownies with a scoop of vanilla ice cream and a drizzle of chocolate sauce for an ultra-decadent treat. The contrast of warm, gooey brownies with cold, creamy ice cream is simply heavenly. - Reese’s Lovers’ Dream:
Chop up some peanut butter cups and fold them into the batter for an extra peanut butter-chocolate explosion. The bits of candy melt into the brownies, making them even more indulgent and satisfying.
These brownies are proof that chocolate and peanut butter are a match made in dessert heaven. The rich, fudgy texture combined with the smooth peanut butter swirl makes them utterly addictive.
