Quick Triple Peanut Butter Brownies are moist, fudgy brownies filled with chocolate chips, peanut butter chips, chopped peanut butter cups, and topped with a yummy peanut butter swirl. These are the best peanut butter brownies and they are extremely simple to make!
We use box brownie mix in this recipe to save time and because it tastes delicious! This literally comes together in a matter of minutes, uses only one bowl, and looks way more complicated than it really is. If you love chocolate and peanut butter, you will absolutely adore these brownies.
Quick Triple Peanut Butter Brownie Key Ingredients
Let’s take a closer look at the ingredients that make up these decadent brownies.
Brownie Mix
I absolutely love Ghirardelli brownie mix. For this recipe, I use their dark chocolate variety because it is so rich and contains chocolate chips in the mix. If you use a different brand or variety that doesn’t contain chocolate chips, feel free to add 1/3 cup to the batter.
Peanut Butter Chips and Peanut Butter Cups
We use Reese’s brand for both the peanut butter chips and peanut butter cups.
Peanut Butter
I recommend using regular creamy peanut butter and would caution against using the natural type with the oil at the top. They may work however the texture of the brownies might be very oily and somewhat off.
Quick Triple Peanut Butter Brownie Process
Although we provide detailed instructions in the recipe below, here is a general overview of the process and some helpful tips along the way.
Prepare Pan
Preheat the oven to 325 degrees F. Spray an 8×8 pan with nonstick spray or line with parchment paper.
Make Brownie Mix
Prepare the brownie mix according to the box instructions. Reserve 1/3 cup brownie mix for the top swirl (set aside).
After the batter is prepared, fold in the peanut butter chips and chopped peanut butter cups. (If your brownie mix does not contain chocolate chips, fold in 1/3 cup.) Pour into the prepared dish and top with dollops of creamy peanut butter and reserved brownie mix. Using a knife, swirl the dollops together but take care to not press into the brownie mix too much. You just want the swirl to remain on top of the brownies. Bake for 40-45 minutes (they may look a bit underdone and that is ok).
How should I store brownies?
Brownies should be covered tightly with aluminum foil or placed in an airtight container and stored at room temperature for up to 4 days.
Tips
- Over-mixing – Take care to not over-mix the batter. When batter is mixed too much, it results in the gluten being activated.
- Doubling recipe – This recipe can easily be doubled and baked in a 13×9 pan. Keep in mind that doubling the recipe will require longer baking time.
- Pan type – The type of pan used may change the baking times. Glass pans often take longer than metal pans because glass slows the flow of heat but will retain heat longer.
My Preferred Tools
You may already have many of these items in your kitchen. I recommend the following for this recipe:
- Stand Mixer – to mix batter
- 8×8 Pan – pan to make single batch
- 13×9 Pan – pan to make double batch

Quick Triple Peanut Butter Brownies
Quick Triple Peanut Butter Brownies are moist, fudgy brownies filled with chocolate chips, peanut butter chips, chopped peanut butter cups, and topped with a yummy peanut butter swirl.
Ingredients
- 1 box Ghirardelli dark chocolate brownie mix
- 1/3 cup peanut butter chips
- 1/3 cup peanut butter cups, chopped
- 1/3 cup creamy peanut butter
Directions
- Step 1 Preheat oven to 325 degrees F. Spray an 8×8 pan with nonstick spray or line with parchment paper.
- Step 2 Prepare brownie mix according to box instructions. Reserve 1/3 cup brownie mix for top swirl (set aside).
- Step 3 After batter is prepared, fold in peanut butter chips and chopped peanut butter cups. (If your brownie mix does not contain chocolate chips, fold in 1/3 cup.) Pour into prepared dish and top with dollops of creamy peanut butter and reserved brownie mix. Using a knife, swirl the dollops together but take care to not press into the mix too much. You just want the swirl to remain on top of the brownies. Bake for 40-45 minutes (they may look a bit underdone and that is ok – if doubling the recipe, brownies will require more time. Begin checking around 50 minutes). You may try testing with a toothpick (this is tricky because of the chocolate chips) and the top will have a matte look instead of glossy.
- Step 4 STORAGE: Cover brownies and store at room temperature for up to 4 days.
- Step 5 DOUBLING RECIPE: This recipe can easily be doubled and baked in a 13×9 pan. Brownies will require longer baking time. Begin checking around the 50 minute mark.
- Step 6 PAN TYPE: The type of pan used may change the baking times. Glass pans often take longer than metal pans because glass slows the flow of heat but will retain heat longer.
