I am currently at the Detroit airport waiting for my flight back to Boston. I’ve spent the past week and a half traveling from place to place. First, to Chicago to photograph for Ambitious Kitchen. Then to Park City, Utah for a blogging retreat. After the first leg of my connecting flight home got delayed for two hours, causing me to miss my second flight, I made the decision to stop in Michigan to see Alex for a few days.

I am currently headed home with a big belly, a full heart, and a mind ready to dive back into work.

It’s amazing what time spent away from your routine can do to revitalize you. I’m so excited for what’s to come in the near future (but more on that later).

Now let’s talk Halloween. Usually I hate Halloween. I hate finding a witty and overpriced costume and finding myself surrounded by slutty nurses and cowboys (The Dress is now a costume. #meta).

But this year I have a variety of desserts to get me excited about Halloween. Starting with these Chocolate Peanut Butter Sandwich Cookies. They’re colorful and festive and, of course, delicious.

It’s like a soft Oreo cookie, but with peanut butter frosting in the middle. Uhm YES PLEASE.

From their mini size to their totally easy recipe,what’s not to love?

And can we talk about the consistency of these cookies? The peanut butter frosting is light and fluffy, but still salty from the peanuts, while the two cookies are chewy and soft– they taste more like a brownie than a cookie if you ask me.

Fun fact: Rebe and I ate all but two of these cookies last week. Ha.

  • Author: Sarah Fennel
  • Prep Time: 20 mins
  • Cook Time: 8 mins
  • Total Time: 28 mins
  • Yield: 16 cookie sandiwches 1x


For the dark chocolate cookies

  • 1/2 cup salted butter, room temperature
  • 1 cup firmly packed light brown sugar
  • 1 large egg, room temperature
  • 1 teaspoon vanilla
  • 3/4 cup all purpose flour
  • 1/3 cup dutch process cocoa powder
  • 1/4 teaspoon baking soda
  • 3/4 teaspoon salt

For the peanut butter frosting

  • 1/3 cup peanut butter
  • 1/4 cup unsalted butter, room temperature
  • 2 tablespoons milk
  • 1 cup powdered sugar

For the drizzle

  • 2 tablespoons peanut butter, melted


  1. Preheat your oven to 350°F. Lightly grease two baking sheets and set aside.
  2. In a medium bowl, cream the butter and brown sugar together until the mixture becomes light and airy (with a KitchenAid, about 3 minutes. with a manual whisk, about 5 minutes). Add in the egg and vanilla.
  3. In another bowl, sift together the flour, cocoa powder, baking soda, and salt. Next, add the dry ingredients into the butter mixture, stirring until just combined, being careful not to overmix the dough.
  4. Using a 1/2 oz cookie scoop, scoop dough onto cookie sheets, leaving about 1.5″ of space in between each ball of dough. Bake for 8-10 minutes, being sure to keep an eye on the consistency of the baking cookies. Let cool completely before frosting.
  5. In a medium bowl, whisk together the peanut butter, butter, milk, and powdered sugar. Place the frosting into a piping bag (or a ziplock bag with the corner cut off) and pipe frosting onto the underside of half of cookies, then sandwich with remaining cookies. Drizzle tops of cookies with melted peanut butter.
  6. Devour.




These are perfection! Sarah, you just made every oreo in history cry with these. I’m seriously considering dropping everything and making them right this second and that is the truth! YUM!

Thank you, Tori! I was dabating to call them soft oreos, but I wasn’t sure if they could compete. Glad you think so!

Laura (Blogging Over Thyme)

Please send me a (ten) dozen of these! K, thanks, bye.

Claudia | The Brick Kitchen

Gorgeous cookies! Love how the cookies are so dark and almost brownie-like, and the peanut butter filling and drizzle is the perfect contrast. Your travels sound like so much fun – can’t wait to hear what you have in store for the future 🙂


These look so, so good! Love that they’re more like brownies than cookies.


I’m a sucker for anything chocolate peanut and these are no exception! Love the texture of these cookies too!

June @ How to Philosophize with Cake

I’d definitely rather have these than any dry store-bought oreo! These look amazing, especially with that layer of peanut butter frosting in the center…mmm 🙂

Angela - Patisserie Makes Perfect

These look fantastic. I love peanut butter so much and I think it should be baked in things more!

Love the pictures, enjoy your blogger retreat.

Liz @ Floating Kitchen

Well missing your flight and getting to see your man sounds way better than actually making your flight. Glad it all worked out! :-). These cookies look amazing. They are a reason to celebrate Halloween – which by the way, I hate too because I’m a big chicken and I get scared by all the awful movies, etc. Yikes! I just want to hide under the covers and shove cookies in my face!


OH MY GOD I want to dive right into that peanut butter frosting. These cookies sound incredible, even better than the store bought Oreos!!

Lauren Gaskill | Making Life Sweet

These are 100x WAYYY better than Oreos! So gorgeous too!

SO much to love about these gorgeous brownie cookies! You can never EVER go wrong with chocolate and peanut butter in my books. Pinned!

Stephanie @ Girl Versus Dough

Um, OK, screw the Halloween candy. I need to get my mitts on these bb’s.

Sarah | Broma Bakery

Right? Homemade is the way to go!

Lily | Kale & Caramel

Wait but seriously. These cookies. If the Girl Scouts sold these cookies, I’d officially buy Girl Scout cookies for the first time in my life. I WANT THEM SO BAD! You’re the mega bomb diggity, girlfriend.

Sarah | Broma Bakery

Ahaha, how amazing would that be?!


Ugh, I want one of these! Glad to read that you got to spend a few impromptu days in Michigan. So great to hang out with you in Utah, lady!

Sarah | Broma Bakery

HI LADY! Yes, it was quite unexpected, but a total treat! Loved hanging out with you too, darlin 🙂


Thanks for a great recipe! Made these yesterday and there were delicious http://cl.ly/image/1u3I3d2e2D0C/IMG_0200.JPG.jpeg. I like that the cookies themselves are versatile too, I could see doing many variations of this recipe by just changing the filling.
