Key Ingredients for Peanut Butter Brownies:
Here’s everything you’ll need to make these irresistible Peanut Butter Brownies:
1/2 cup (1 stick) unsalted butter – melted
1 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
1/2 cup all-purpose flour
1/3 cup unsweetened cocoa powder
1/4 teaspoon baking powder
1/4 teaspoon salt
1/2 cup creamy peanut butter – slightly warmed for easier swirling
1/2 cup chocolate chips (optional) – for extra chocolaty goodness

Step-by-Step Instructions:
Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking pan or line it with parchment paper for easy removal.
Prepare the brownie base: In a large bowl, mix the melted butter and sugar until smooth. Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract.
Combine the dry ingredients: In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt. Gradually add this dry mixture to the wet ingredients, stirring until fully incorporated.
Pour the brownie batter into the prepared baking pan and smooth the top with a spatula.
Peanut butter swirl: In a microwave-safe bowl, heat the peanut butter in the microwave for about 20-30 seconds until it’s slightly runny. Drop spoonfuls of peanut butter onto the brownie batter and use a toothpick or knife to swirl it through the batter, creating a marbled effect.
Bake for 25-30 minutes or until a toothpick inserted into the center comes out with a few moist crumbs. Be careful not to overbake, as you want your brownies to remain fudgy.
Cool and slice: Let the brownies cool in the pan for 10 minutes before transferring them to a wire rack. Once fully cooled, cut into squares and enjoy!
What to Serve Peanut Butter Brownies With
While these Peanut Butter Brownies are delicious on their own, why not take it up a notch with a few complementary dishes? Here are some ideas to pair with your brownies:
Vanilla Ice Cream: The creamy, cold ice cream perfectly balances the richness of the brownies.
Coffee or Milk: A cup of coffee brings out the chocolate flavor, while milk is the classic companion to any brownie.
Fresh Fruit: A side of fresh berries adds a touch of tartness that contrasts beautifully with the sweet, fudgy brownies.
Top Tips for Perfecting Peanut Butter Brownies
Don’t Overmix: When mixing the wet and dry ingredients, be careful not to overmix the batter. Stir until just combined to keep the brownies tender.
Peanut Butter Consistency: For the best peanut butter swirls, make sure the peanut butter is soft and slightly warmed. If it’s too thick, it won’t swirl as easily.
Customize Your Brownies: Feel free to add chocolate chips, a sprinkle of sea salt, or even chopped peanuts for extra texture and flavor.
Storing and Reheating Tips
Once you’ve baked these delicious Peanut Butter Brownies, you’ll want to know how to store them for maximum freshness:
Storage: Store leftover brownies in an airtight container at room temperature for up to 4 days. If you want them to last longer, refrigerate them for up to a week.
Freezing: These brownies freeze beautifully! Simply wrap them individually or as a whole batch in plastic wrap and aluminum foil. Freeze for up to 3 months.
Reheating: When ready to enjoy, warm up a brownie in the microwave for about 15-20 seconds for that freshly-baked taste. Add a scoop of ice cream, and you’ve got yourself a dessert to remember.
FAQs
When to Add Peanut Butter to Brownies?
To achieve the perfect peanut butter swirl in your brownies, it’s best to add the peanut butter after pouring the brownie batter into the pan. Once the batter is spread evenly, drop spoonfuls of peanut butter onto the surface. Then, use a knife or toothpick to swirl it into the batter, creating a marbled effect. This ensures the peanut butter blends beautifully with the chocolate, creating a rich and satisfying flavor in every bite.
What Happens if You Put Too Much Butter in Brownies?
If you add too much butter to your brownies, the texture may become overly greasy and soft. This can lead to a lack of structure, making your brownies fall apart easily. Additionally, the extra fat can make the brownies excessively rich, overpowering the chocolate flavor. To avoid this, it’s best to stick to the recommended amount of butter in the recipe for the perfect balance of moisture and structure.
What Can I Add to Brownie Mix to Make It Taste Better?
To elevate the flavor of your brownie mix, consider adding a teaspoon of vanilla extract or a pinch of espresso powder. These additions help intensify the chocolate flavor. For a more indulgent twist, you can also mix in chocolate chips, chopped nuts, or swirl in peanut butter. Furthermore, a sprinkle of sea salt on top before baking can balance the sweetness and enhance the overall taste.
What Causes Brownies to Crumble?
Brownies can crumble for several reasons, but the most common cause is overbaking. When brownies bake for too long, they lose moisture, leading to a dry and crumbly texture. Another factor could be not measuring ingredients correctly—too much flour or not enough fat can affect the texture as well. To prevent crumbling, bake the brownies just until a toothpick inserted into the center comes out with a few moist crumbs.
Are Peanuts Good in Brownies?
Absolutely! Peanuts are a great addition to brownies. Their crunchy texture and slightly salty flavor pair wonderfully with the sweet and rich chocolate, creating a perfect contrast. You can either chop the peanuts and mix them into the batter or sprinkle them on top for added texture. Plus, the peanut flavor complements the brownies’ fudgy richness, making them even more delicious.
What Is the Best Way to Use Peanut Butter?
Peanut butter is incredibly versatile, and there are many ways to use it. For baking, you can swirl it into brownies, cookies, or cakes to add richness and flavor. If you prefer savory dishes, try adding it to stir-fries, sauces, or dressings for a creamy texture and subtle nuttiness. Additionally, spreading peanut butter on toast, pairing it with fruits like bananas, or using it in smoothies are all fantastic ways to enjoy this creamy delight.
