Peanut Butter Brownie Variations
- You can choose to make the brownie batter from scratch, but honestly, brownie mixes these days are so good that you wouldn’t miss out by grabbing a box. Plus, there are boxed brownie hacks that allow you to doctor up the brownies and make them even more decadent and rich.
- Add even more peanut butter flavor in every bite by sprinkling peanut butter chips into the batter before baking!
- There are so many varieties of Reese’s brownies now. I particularly love the dark chocolate peanut butter ones. Also, around different holidays, they have different shaped ones. For example, around Halloween they have the pumpkin-shaped Reese’s peanut butter cups. You can use whichever in this Reese’s brownie recipe!
Storage Instructions
These peanut butter brownies will last up to 4 days at room temperature if covered and wrapped tightly!
Pro tip: zap them in the microwave for 10-15 seconds to have a warm, gooey, center.

I need these in my life. Like now!
Yum! i can’t wait to try these! They would be perfect to take to someone who needs a smile sent their way.
I’d have a very hard time not heating the whole pan…they look incredible!
If we lived closer, you wouldn’t have had any reese’s cups left because I would’ve come over + devoured them all. =) And these brownies? Look amazing! Wish I had one for breakfast! =)
Haha, we still get the hoards at our house – we run out of candy every year no matter how much we buy! Of course then we go and buy some on sale to have for snacking afterward :) These brownies sound so fantastically decadent!
Reeses are my favorite candy..we keep them in our freezer year round. Im so in love. The gooey-ness here is making me want to eat these up for breakfast! Beautiful!
My mouth is watering— yum!
Halloween is definitely different now. Although I have never taken my kids to the mall to Trick or Treat…we usually just pick a safe neighborhood and then trail the kids closely. I need to go steal all the Reeses out of my kids bags because these brownies look super duper incredible. Love me some Reeses inside a chocolatey brownie:-)
These look dangerous!
