Fudgy Brownies with Peanut Butter Chips

These Peanut Butter Chip Brownies are a simple twist on a fudgy brownie I’ve made many times. (Hello, Fudgy Cookies and Cream Brownies and Pecan Lovers’ Brownies!) They’re not fancy or elaborate. They’re just really, really good, especially if you’re a big fan of chocolate and peanut butter like I am.

Peanut butter chips are responsible for all of the peanut butter flavor here. They are such an easy way to add a little or a lot of peanut butter flavor to baked goods. And these brownies are really packed with peanut butter chips. In fact, I’m not sure I could have gotten any more mixed into the batter. If you’d like a few less, then feel free to dial it back to suit your tastes.

These brownies are made with both melted chocolate and cocoa powder for a big, fudgy chocolate experience. Plus, you get a little bit of that crackly top that cocoa powder often gives brownies.

If you’re a chocolate and peanut butter fan looking for a quick and easy treat, then I think you’ll love these Peanut Butter Chip Brownies. Brownies with peanut butter chips aren’t exactly revolutionary in the baking world, but I can tell you that they 100% get our seal of approval!

And if you want even more brownies with peanut butter, try Peanut Butter Brownies, Peanut Butter Streusel Brownies, and Brownie Peanut Butter Cups.

What You’ll Need

Scroll to the recipe card at the bottom of this post for ingredient quantities and full instructions. Here are some helpful notes about the ingredients.

  • Unsalted butter
  • Unsweetened chocolate – Chop the chocolate so it melts more easily.
  • Cocoa powder – I recommend unsweetened cocoa powder for these brownies. If yours looks lumpy, sift it before mixing.
  • Granulated sugar
  • Eggs – Allow these to come to room temperature for best results.
  • Vanilla extract
  • All-purpose flour – As always, measure by weight or use the spoon and sweep method. Learn more: How to Measure Flour
  • Salt
  • Peanut butter chips – Look for these alongside the chocolate chips with the baking ingredients.

How to Make Peanut Butter Chip Brownies

Prepare for baking. Heat the oven to 350°F. Line a 9-inch square baking pan with parchment paper, and grease the paper. Alternatively, skip the liner and grease the pan.

Melt the butter and chocolate. Place the butter and chocolate in a large microwave-safe bowl. Heat at half power in the microwave in 30-second increments until the butter melts and the chocolate melts when stirred. Stir until smooth, and then set aside to cool slightly. It should be warm to the touch but not hot.

Continue mixing. After the chocolate mixture has cooled, whisk in the cocoa powder, followed by the sugar, then the eggs and vanilla. Add the flour and salt, and mix until combined.

Add the peanut butter chips. Stir the peanut butter chips into the brownie batter.

Bake. Spread the batter evenly in the prepared pan. Bake 30 to 35 minutes. When the edges are set and a pick inserted into the center comes out with a few moist crumbs, the brownies are ready to come out of the oven.

Cool. Place the pan on a wire rack, and allow the brownies to cool before cutting into bars.

Tips for Success

Here are a few tips to make your Peanut Butter Chip Brownies turn out perfectly!

  • Use good quality chocolate. Brownies are all about the chocolate, so be sure to use good chocolate and cocoa powder.
  • Use a light-colored metal pan. Your brownies will bake more thoroughly and evenly.
  • Customize! You can use a different flavor of baking chips, or substitute nuts or another favorite add-in.

How to Store

After the brownies have cooled, place them in an airtight container. They should keep at room temperature up to 3 days.

Can These Brownies Be Frozen?

Yes, you can freeze these brownies. Once they’ve cooled completely, place them in a freezer-safe airtight container or sealable bag. If you like, wrap the brownies individually before placing them in the container so you can easily grab one or a few at a time. Properly stored, they should keep in the freezer up to 3 months. Thaw for an hour or two at room temperature, or warm briefly in the microwave.

  • 3/4 cup (170g) unsalted butter
  • 2 ounces (57g) unsweetened chocolate, roughly chopped
  • 1/4 cup + 2 tablespoons (31g) unsweetened cocoa powder
  • 1 & 3/4 cups (350g) granulated sugar
  • 3 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup (120g) all-purpose flour
  • 1/2 teaspoon salt
  • 1 & 3/4 cups (292g) peanut butter chips*


  1. Preheat oven to 350°F. Grease or line a 9-inch square baking pan.
  2. Place the butter and chocolate in a large microwave-safe bowl. Heat in the microwave at half power in 30-second increments until the butter has melted and the chocolate melts when stirred. Stir until smooth. Allow to cool slightly.
  3. Whisk in the cocoa powder, followed by the sugar, and then the eggs and the vanilla. Add the flour and salt, and whisk until combined.
  4. Stir in the peanut butter chips.
  5. Transfer the batter to the prepared pan and spread evenly.
  6. Bake 30 to 35 minutes, or until the edges are set and a pick inserted into the center comes out with a few moist crumbs attached.
  7. Cool the brownies in the pan on a wire rack. Then cut into squares and serve.


*I usually have larger bags of peanut butter chips in my kitchen, but many brands are available in 10 ounce bags which contain about 1 & 2/3 cups. If that's what you have available, then that slightly lesser quantity will be just fine.

Store in an airtight container at room temperature up to 3 days or in the freezer up to 3 months.

  1. I was planning to send care packages to my son and grandson so I thought I would make these. I doubled the recipe and used a 9×13 pan. I didn’t have time to go to the store so I used a mix of ingredients: butterscotch morsels, chocolate chips and chocolate and peanut butter morsels from Trader Joe’s. These are spectacular! So moist and chocolaty. Really outstanding. I’m so glad I saw the recipe today and tried it out. Thank you so much for such a winner!

  2. These brownies look so delicious and chocolatey! I love the addition of peanut butter chips!

  3. Ido not have peanut butter chips. But I have peanut butter liquid form (thick) which we use on bread. Can i use this instead of peanut butter chips
