I’m sure you have leftover Halloween candy. We have TONS. We stupidly spent way too much money on it, too. It was our first Halloween in our new house and the neighborhood is swarming with kids. We were both certain we’d have a ton of kiddos come to the door. We decided to be prepared. Annnnd we shouldn’t have. We had like tops 20 kids come.

Halloween just isn’t like what it used to be anymore. You could always bank on having hoards of kids coming to your door and running out of candy. Now, you’re basically begging for kids to come take the candy and when they do show up, you give them seven fistfuls of candy because you know they’re the only ones you’re getting that night.

It’s funny how generations change. When I was young, Halloween was huge. We didn’t have to really worry about safety or danger of other people, you know? It was a lot less rules. Now, it’s like parents are so scared that they don’t let their kids go trick-or-treating anymore and they play it safe and take them to the mall to do the trick-or-treating. Maybe by the time my friends and I start having kids, it’ll change again and we’ll bring back Halloween and we’ll all run out of candy again at our houses.

So, since we had way too much leftover candy, I stole all the Reese’s peanut butter cups and baked them into a brownie. I figured it’d be a good idea, and let me tell you: it was better than good. It was brilliant. The fudgey and chewy brownie envelopes the Reese’s peanut butter cup. It’s the best surprise, ever, when you take bite into what you think is just a plain ole brownie. Chocolate and peanut butter. Two of the best ingredients collide and make a happy, decadent dessert :)

Made these last night, and everyone in the house loved them. We decided to use the white chocolate Reese’s cups, and I’m glad I did! We thought it would cut down just a smidge of the richness but in a good way...and it did. I did cut down on the sugar just a little and mixed white and brown sugar. Will definitely be making these again!

Hi! Really curious. How much of each item for a 9x13 pan??


Monday 18th of September 2017

Hi, 9x9 is not much different than 9x13. You don't have to change anything. Your brownie will just be a little thinner but slightly.

Could you make these using a brownie mix?


Friday 23rd of December 2016

Yes, definitely!

Is there a way to make these without the chocolate caramelizing and creating a hard, crunchy bottom?


Sunday 3rd of April 2016

I would add more brownie batter to the bottom layer and instead of pushing down the Reese's cups, just gently plop them on top of the batter then cover with the remaining brownie batter. Hope that helps!
