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.

Hi Julie
you are So right about chocolate and peanut butter being two of the best ingredients. What a marriage made in Heaven, right?
Some time ago I made a peanut butter and fudge ice cream pie which so many of us got to enjoy.
Another amazing combination is orange and chocolate i.e. jaffa. Several times now I’ve added either orange juice and/or orange zest into a chocolate cake or brownie with really good results.
Thanks for sharing your recipe with us.
I like how you layered the candy in the brownie mix. Neat idea; hadn’t thought of trying that.
Interesting because I bake Reeses’ brownies for a local restaurant. Alas, though, I’m forced to use a boxed mix because it’s cheaper.
But at home? Yeah…from scratch.
What a seriously great idea! I wish I would have thought of it first ;) But really, brownies will be the death of me one day. They are the one think I cannot seem to bake. It is pretty much always a fail… I guess I need to practice haha. These look beautiful Julie! :)
oh my GAWD. My fave in a brownie. I LOVE this.
These look UHmazeballs!
I agree about Halloween… another thing I’ve noticed (I live in the Midwest) is that nobody trick-or-treats when it’s dark outside. Where’s the fun in that???
Halloween has changed, it’s quite sad. But these brownies do make up for it
Best.Brownies.Ever.
This is the best thing ever.
Yep, I’m convinced, This is the most PERFECT way to use up any reese’s PB cups from post halloween trick-or-treating. The brownies looks insane Julie. You know how I feel about PB and chocolate!!!
Ugh, we have so much candy left over. We weren’t sure if we would have any kids in the complex our new townhome is in. But, nope, not one. Too many young people living here. Oh well, I guess I will just HAVE to make these amazing brownies! ;)
