How to Make Peanut Butter Stuffed Brownies
Make brownie batter according to directions on package. Then pour about 2/3 mixture into the parchment lined pan. Cream butter, peanut butter and powdered sugar until smooth. Drop spoonfuls of peanut butter filling on top of brownie batter.
Add remaining 1/3 brownie mixture on top of peanut butter and smooth with spatula. Bake for 30 minutes, or until a toothpick comes out clean. Remove from oven and let cool completely.
To make chocolate ganache, heat the heavy cream in the microwave for about 30 seconds, or until very hot. Then pour on top of the chopped chocolate (photo below) and cover with saran wrap. Let sit for a few minutes in order to melt.
Stir ganache until smooth, then pour over cooled brownies and smooth with a spatula. Refrigerate for 1 hour prior to serving.
Baking Tips
- Easy clean up: Line your pan with parchment paper for easy removal.
- Add candy: Add chopped Reese’s to the peanut butter filling before baking or on top of chocolate ganache.
- More chocolate: Feel free to mix in some chocolate chips to your brownie batter.
- Less chocolate: You could omit the chocolate ganache if preferred.
- Don’t over bake! You want the brownies to be gooey and fudgy. Oven timing can vary, so use a toothpick to determine if brownies are done.

FAQs
Sure! If there is a peanut butter allergy, try almond butter or cashew butter.
Yes, use the same recipe and proportions then add brownie batter to a 9×13″ baking dish. Baking time will likely be shorter, about 20-25 minutes. Your peanut butter brownies will be more thin.
If your toothpick is still coming out fudgy another way to tell when the brownies are done are to look at the center. If the brownies are puffed up this means the egg is cooked through.
Store chocolate peanut butter brownies in an airtight container at room temperature for 3-5 days. You can also store them in the fridge and they get decadently fudgy.

Would your home made brownie recipe work vs using a boxed brownie mix?
Yes! That is perfect! I love that idea. Thanks for using both recipes together!

These were so easy to make and crazy delicious. Our family loves peanut butters much!
This was so good! So hard to resist!
You can never go wrong with this combination!!
That frosting on top is incredible. These are my kind of brownies!
The peanut butter chocolate combo is the best!
I made these using pillsbury’s all purpose gluten free flour for the brownies and they were delicious. But I used dark chocolate Reeses on top to contrast the frosting
Yum!
Would it be best to do them at night if there are going to be for lunch the next day?
Yes, definitely!
Have you ever made these only gluten free? Could you substitute the flour or would it taste bad?
Thanks
Brianna
Hi Brianna! I haven’t tried this with gluten free flour, but if you have tried it with other recipes, it should work just fine! :)
What do you mean by 1 cube of cream cheese – is that 4 oz or 8 oz
8 oz! :)
