Key Ingredients
- Butter: This is the base of our brownie recipe, providing a rich and buttery flavor to the mix.
- Peanut Butter: It adds a creamy, nutty flavor that pairs perfectly with the chocolate chips.
- Granulated Sugar: This sweetens the brownies and also helps to give them a nice, crisp edge.
- Brown Sugar: The molasses in brown sugar adds a deeper, more complex sweetness to the brownies.
- Eggs: They help to bind the ingredients together and also add some moisture to the mix.
- All-Purpose Flour: This is the main dry ingredient in our recipe, providing the structure for the brownies.
- Baking Powder: This is our leavening agent to give us the perfect texture to the brownies.
- Vanilla Extract: It enhances the chocolate and peanut butter flavors, giving the brownies a more rounded and full-bodied flavor.
- Salt: A pinch of salt helps to balance the sweetness of the other ingredients, making the flavors more pronounced.
- Chocolate Chips: These will melt into the brownie as it bakes, leaving pockets of melted chocolate throughout.
Equipment
- 9×9 Square Baking Pan – This is where you’ll bake the brownie mixture. Make sure to grease it well so the brownies don’t stick. You can alternatively use a medium rectangle baking dish.
- Hand or Stand Mixer – You’ll need this to cream the butter and peanut butter, as well as to mix the sugars and eggs. It makes the process much easier than doing it by hand.

How to Make Peanut Butter Chocolate Chip Brownies
Preparation
To start, preheat your oven to 350˚ F and grease your 9×9 baking dish. This will make sure that your brownies don’t stick to the pan and are easy to remove after baking.
Step 1 – Cream the Butter and Sugars
In a bowl, cream together the butter and peanut butter until they are light and fluffy. Then, slowly add the white sugar and brown sugar, and beat this mixture well. This will give your brownies a sweet, creamy base.

Step 2 – Add the Eggs and Dry Ingredients
Next, add the eggs one at a time, beating well after each addition. Once the eggs are incorporated, add the flour, baking powder, and salt. Mix these dry ingredients well with the butter and sugar mixture.

Step 3 – Add the Chocolate Chips
Now, it’s time to add the star of the show – the chocolate chips. Also, add the vanilla extract for a hint of flavor. Mix these into your batter until they are well distributed.

Step 4 – Spread the Batter and Bake
Pour your brownie batter into the greased baking dish and spread it out evenly. Then, pop it into your preheated oven and bake for 30-35 minutes. You’ll know it’s done when the top is set and a toothpick inserted into the center comes out mostly clean.

Step 5 – Cool and Serve
Once baked, let your brownies cool in the dish. This will help them set and make them easier to cut. After they have cooled, you can cut them into squares and they’re ready to serve.
Expert Tip
To guarantee that all of your ingredients are well incorporated at each step of the mixing process, make sure to scrape the sides of the bowls. This simple step will ensure that your peanut butter chocolate chip brownies have a perfect, uniform texture.
Recipe Variations
- Add Nuts: If you’re a fan of nutty brownies, try adding a cup of your favorite chopped nuts to the batter. This will add a delicious crunch and extra flavor to your brownies.
- Glaze or Icing: For a sweeter treat, consider serving your peanut butter chocolate chip brownies with a chocolate or peanut butter glaze or icing. This is a great option for special occasions or when you’re craving something extra decadent.
- Remove Chocolate Chips: If you want to highlight the peanut butter flavor, feel free to omit the chocolate chips from the recipe. Your brownies will still be deliciously sweet and full of peanut buttery goodness.

What to Serve With
- For a classic and delicious pairing, serve these peanut butter chocolate chip brownies with a cold glass of milk. The creamy, cool milk is the perfect contrast to the rich, fudgey brownies.
- If you’re a fan of a la mode, you can serve these brownies with a scoop of vanilla ice cream. The cold, creamy ice cream compliments the warm, gooey brownies, making for a truly decadent dessert.
- For a fun twist, try crumbling these brownies over a bowl of your favorite ice cream. It adds a delicious, chocolatey crunch to your ice cream, and makes for a great presentation.
- If you’re hosting a brunch, these brownies are a great addition to your spread. Pair them with a cup of hot coffee for a sweet, yet slightly caffeinated treat.
