Chocolate Peanut Butter Sandwich Cookies

Sometimes I want to love what everyone else loves…but don’t. Like, harem pants (my thighs don’t need help looking larger – thanks) or frappuchinos (real coffee, please) or sparkly shoe clips  or Mad Men (boring). Peanut butter and chocolate is one of those things that the entire world LOVES. And I do, too.

It’s the classic of classic combos. And there’s good reason. Something magical occurs when chocolate and peanut butter come together. The clouds open, the symphony sounds, a Lisa Frank rainbow appears in the sky and smiles appear.

This cookie has chocolate, peanut butter, oatmeal and a good amount of salt all mixed into one.

Chocolate Peanut Butter Sandwich Cookies

My biggest pet peeve in the world (and I’m being melodramatic) is when I eat a sandwich cookie and the cookie part is hard or crispy.

I loooove crispy cookies but not in the context of a sandwich situation. They need to be chewy and soft, or else the filling oozes out – and not like an attractive “oooo” ooze, but a “it’s on my shirt now” ooze.

Chocolate Peanut Butter Sandwich Cookies

These oatmeal chocolate cookies are chewy. I like them. These are adapted from these Meyer Lemon and Currant Oatmeal Cookies that I posted a few months ago. This was a time when meyer lemons had just hit the scene and Amelia still wasn’t housebroken. I’m glad it’s now and not then.

(Psst: Another example of salty, chocolatey and peanut buttery stuff on this blog: A Very Giant Reese’s Peanut Butter Cup.)

Isn’t peanut butter so pretty when sugar, salt and butter are added?

This is a peanut butter frosting that’s sweet and salty and all that jazz. Peanut butter does very nice swoops.

And this picture here is just all about me showing you my new manicure. That is all.

Chocolate Peanut Butter Sandwich Cookies

I added a few chocolate chips to the last few cookies I baked up and dude are they so good with added chocolate. Not a necessity. No.

I sat yesterday debating whether or not I needed to remake them, adding chocolate chips. I came to the grand conclusion of no. They’re chocolatey on their own. But as we all know, a little extra chocolate ain’t hurt nobody.

Chocolate Oatmeal Peanut Butter Sandwich Cookies

Serving Size: 16 Sandwich Cookies



  • 1 1/2 cups all-purpose flour
  • 1/4 cup Dutch processed cocoa powder
  • 1 cup 8 ounces unsalted butter, room temperature
  • 1 3/4 cups light or dark brown sugar
  • 2 large eggs
  • 2 teaspoons pure vanilla extract
  • 1 teaspoon baking soda
  • 1 1/4 teaspoon fine-grain sea salt
  • 2 3/4 cups old fashioned rolled oats

Peanut Butter Frosting:

  • 2 tablespoons unsalted butter, room temperature
  • 3/4 cup powdered sugar, sifted
  • 1/2 cup creamy natural peanut butter, *See note below
  • 3 tablespoons whole milk
  • 1/2 teaspoon sea salt, or to taste


  • Preheat your oven to 350 degrees F.
  • In a medium bowl, mix together the all-purpose flour and cocoa powder; set aside.
  • In a large bowl, cream together the butter and brown sugar for about 1-2 minutes, until light and fluffy. Add the eggs, vanilla extract, baking soda and salt; mix until thoroughly combined. Fold in the oats until completely combined. Next, fold in the flour and cocoa powder mixture and mix until there are no longer any specks of flour.
  • Using a 2-inch cookie scooper, drop rounds of cookie dough onto a parchment-lined baking sheet, spacing the cookies about 2-inches apart and flattening each cookie slightly. Transfer the baking sheet to the oven and bake for 10-12 minutes, until the cookies’ edges are firm but the edges are still soft to the touch. Using a spatula, carefully transfer the cookies to a cooling rack.
  • While the cookies are cooling, make the peanut butter frosting. Add the room temperature butter, powdered sugar, whole milk and salt to a medium bowl. Using a standup mixer or a good ol' fashion spatula, beat all of the ingredients together until light, fluffy and smooth.
  • To assemble the sandwiches, scoop a teaspoon or two of peanut butter frosting onto the center of half of the cookies; smooth it out with a knife and place the remaining cookies on top, gently pressing on them to squeeze the filling so it reaches the edges.

Note: I used creamy natural peanut butter with no sugar added; if your peanut butter has sugar, I'd recommend scaling back on the powdered sugar and doing it to taste.

    I actually prefer oatmeal with chocolate cookies. Maybe it is texture but I find not many people like this combo down under. Pb and chocolate is always a winner in my books; salty and sweet trend is something I could get use to.

    SOLD! I feel so bad for those suckers with peanut allergies. My sister was allergic when she was little and OMG, for me to eat a peanut butter sandwich in front of her was like torture! Anyway, I am obviously a peanut butter addict so you are definitely speaking my language.

    Fabulous, and I agree about crispy cookies not making it as the outsides of the sandwich!

  • Reply Stacey April 19, 2013 at 10:17 am

    These are some little beauties! I agree wholeheartedly about sandwich cookie cookies being soft. Must be soft! I’ve officially declared THIS the recipe that will get me a’bakin’ again. A week or two ago I set out to make cookies for the neighbors, who’d been dealing with the tomfoolery of our bad black labs all week. I baked late into the night, and then put the glorious dough balls in the oven. Set the timer for 10 min. Nada. 10 more minutes. Still nothing. 5 MORE min. Those fat little dough balls just stared at me. FINALLY I realized that I’d turned off the oven after dinner and then never turned it back on. My baking pride is mortally wounded and I haven’t done anything since!

    I totally know that feeling about not loving what everyone else loves (we talked about Mad Men on twitter…). Confession: I don’t love putting butter on pancakes. Nor do I like certain exotic foods, like frogs legs.

    But peanut butter and chocolate. Yes. Bring me lots of it.
