Peanut Butter Cup Brownies with Oreo Crust

I’m just gonna say what you’re all thinking: these brownies are ridiculous. But in a very, very good way.

They’re what happens when Crack Brownies marry Slutty Brownies: they’re fudgy, chocolatey Peanut Butter Cup Brownies that have an Oreo Crust.

Like I said, ridiculous. But you want them anyway.

Peanut Butter Cup Brownies with Oreo Crust - the BEST brownie ever!

Sometimes I surprise myself. Sometimes I have to just gape in awe at my brilliance as a dessert thinker-upper.

Yes, that’s my new title. Like it?

Dessert Thinker-Upper (noun): a person who thinks deeply and seriously about dessert and who comes up with ridiculous dessert recipes that make you drool.

So in my role as Dessert Thinker-Upper, I’m always thinking about my next new dessert. I think about it at the gym, in the shower, and while I’m driving. I think about desserts when I’m trying to play Life with my daughter and when my husband talks to me about NFL Total Access. Long car trips? The perfect time for thinking up crazy ridiculous desserts.

If you read my post yesterday, you’ll know all about my trip to Palm Springs. On the way home I was thinking on a dessert I could make to send to our friends who lent us their condo, to say thanks. Because that’s how I say thank you: with dessert.

Makes you want to do something nice for me, doesn’t it?

Reese's Brownies with Oreo Crust - the BEST brownie ever!

Anyway, the treats needed to be mailed, so I thought cookies then bars then brownies. Because besides pie, I always think about brownies.

My next website needs to be Crazy for Brownies.

And if I could pick one kind of brownie to eat, it would have a crust. Brownies are just better with crust! If you don’t believe me, try it. You’ll thank me.

Naturally my next thought was an Oreo Crust. Because, well, who doesn’t love that?

And then, well. I thought, go big or go home. And I decided I would throw chopped Reese’s Peanut Butter Cups on top.

Oreo Peanut Butter Cup Brownies

I mean, do I even need to describe how good these are?

Crunchy Oreo crust.

Rich, fudgy, thick chocolate brownie. (These are baked in a 9×9 pan for ultimate thickness!)

And, BTW, fudgy, gooey brownie is where it’s at. Cakey, dry, sub-par brownies need not apply at Crazy for Brownies.

Chopped Miniature Reese’s Peanut Butter Cups.

Like I said, ridiculous.

In a good way.

Peanut Butter Cup Brownies with Oreo Crust - the BEST brownie ever!

My job is hard. But someone has to do it.

You’re welcome.

Peanut Butter Cup Brownies with Oreo Crust

Yield: 16 brownies

Peanut Butter Cup Brownies with Oreo Crust

This brownie is ridiculous! It has three layers of fabulous: an Oreo crust, a layer of fudgy rich brownies, and a topping of chopped peanut butter cups. This is a dessert for a serious chocoholic!


    For the Crust:
  • 20 Oreos
  • 1/4 cup butter, melted
  • For the Brownies:
  • 2 ounces unsweetened baking chocolate, coarsely chopped
  • 2 ounces semi-sweet baking chocolate, coarsely chopped
  • 3/4 cup unsalted butter
  • 1 3/4 cups sugar
  • 3 eggs
  • 1/4 teaspoon salt
  • 1 tablespoon vanilla extract
  • 2 tablespoons unsweetened cocoa powder (I used Hershey’s Special Dark)
  • 1 cup all-purpose flour
  • 25 Miniature Peanut Butter Cups (Reese’s), unwrapped and coarsely chopped


  1. Preheat oven to 350°. Line a 9x9” pan with foil and spray with cooking spray.
  2. Crush Oreo cookies to a fine crumb using a food processor. You can also place them in a gallon size ziploc bag and roll it gently with a rolling pin until you have a fine crumb. Stir cookies into melted butter and press into the bottom of your pan. Chill until brownies are prepared.
  3. Place the two baking chocolates and butter in a large, microwave safe bowl. Heat on HIGH power for 2-3 minutes, stirring every 30 seconds, until chocolate is smooth. Stir in sugar. Add eggs, salt, vanilla, and cocoa and stir well. Add flour and stir carefully.
  4. Spread batter in prepared pan. Sprinkle the top with the chopped peanut butter cups.
  5. Bake about 31-34 minutes, until a toothpick 1 inch from the outside of the pan comes out mostly clean. The center may still be a little jiggly. Let cool before cutting.
  6. Store in an airtight container at room temperature for up to 4 days, or place in an airtight container and freeze for up to one month.


When unwrapping and chopping the peanut butter cups, if the candy is too warm and the chocolate starts to peel off with the wrapper, chill the wrapped candy for about 5-10 minutes, then try again.

  8. Dorothy, these brownies look like they have the ultimate fudgy texture! That’s basically my only criteria for a brownie….so the added bonus of Oreo crust and peanut butter cups on top just put me over the edge! I’m sitting here trying to think of what I could offer to do for you so I could get a thank you gift of these brownies mailed to me…

  16. OMG! These sound (and look!) amazing!!! I’m not a huge Oreo fan, but somehow, I don’t think that Oreo crust would be a bad thing at all! I NEED to make these! :)

  17. A Dessert Thinker-Upper — I totally want this title too! Long car trips are the best for mind wandering dessert recipe thoughts, or even just the 1-1.5 hours it takes to drive to my parents’ house. Long runs work too, although half the time I start thinking about how much a certain muscle hurts or why I should’ve woken up earlier to avoid the heat. (Crazy Sacramento!) But you definitely outdid yourself with your chocolaty + PB-y creativity with these brownies Dorothy!!
