Bars, Blondies & Brownies/ Cookies/ Desserts

PB Cookie Chocolate Brownie Nutter Butter Bars

Whew…that was a mouthful.  And that these bars are.  A layer of peanut butter cookie dough, topped with Nutter Butter cookies and then smothered with a rich, chocolate brownie batter and then baked up into a bar worthy of destroying your diet for.

**One quick note before we dive into chocolate-peanut butter heaven…I made the cookie dough and brownie batter from scratch for this recipe, but if you are looking for an easy dessert, scroll all the way down to the bottom, for directions on how to make these bars using refrigerated cookie dough and box mix brownies!**

James gets a lot of what I bake…which means everyone James works with, gets a lot of what I bake.  I am thankful for a firehouse full of firemen who are always eager to try my dessert creations.  James moved to a new firehouse last week, which means a whole new crew he is working with now.  So this insane recipe I created, was a collaboration of brainstorming between the hubs and I, because he wanted me to make him something for his first tour with his new crew at MFD Station 3.  My apologies in advance boys, for destroying any diet you may be on….

James loves peanut butter cookies and loved the Slutty Brownies I made not so long ago (I am still hating that title for the recipe—but that’s what they are called).  So I took a spin off of those brownies and came up with these amazing bars!  Seriously.  If you love peanut butter cookies, brownies and Nutter Butters, then this is the ultimate dessert for you, because I have combined all three into one glorious cookie-brownie bar!  Get milk y’all.  You will need milk for when you eat these!

Make your peanut butter cookie dough and press it evenly into your pan…

And get your Nutter Butters…family size is always a good idea!  Because who will complain about having extra Nutter Butter cookies in the house?!

Press those Nutter Butters into your peanut butter cookie dough!

Next pour your brownie batter ALLLLLLL over that peanut butter goodness!

And then top with sprinkle hearts…because it’s almost Valentine’s Day and anyone you make these for will love you forever!  And now these are ready to bake!

PB Cookie Chocolate Brownie Nutter Butter Bars

Print Recipe
Serves: 30 Cooking Time: 35-45 minutes


  • 1/2 cup unsalted butter, room temperature
  • 1 cup light brown sugar, packed
  • 3/4 cup creamy peanut butter
  • 1 egg, room temperature
  • 2 teaspoons vanilla extract
  • 1-1/2 cups all purpose flour
  • 3/4 teaspoon baking soda
  • 20 whole Nutter Butter cookies
  • 4-ounces unsweetened baking chocolate, cut into chunks
  • 10 tablespoons butter
  • 2 cups white granulated sugar
  • 3 eggs, room temperature
  • 2 teaspoons vanilla extract
  • 1 cup all purpose flour



Preheat oven to 350-degrees. Line a 9x13-inch baking pan with parchment paper and spray bottom and sides with baking spray. Set aside.




In the bowl of a stand mixer, with the paddle attachment affixed, cream the butter on medium-high speed until smooth and creamy. Add the brown sugar to the butter and mix until light and fluffy. Add the egg and vanilla extract and beat into the mixture until incorporated. Add the peanut butter and mix on medium-high speed until completely combined. Turn the mixer to low speed and slowly add the flour and baking soda, mixing on low until barely combined.


Remove bowl from mixer and use a rubber scraper to ensure all ingredients are incorporated and then spoon cookie dough into the prepared baking pan. Use the rubber scraper to smooth the cookie dough out into an even layer in the baking pan.




Gently press 20 whole Nutter Butter cookies into the peanut butter cookie dough layer.




In a microwave safe bowl, add the unsweetened chocolate and butter, and microwave until butter and chocolate are completely melted. Stop every 20-seconds to stir the mixture to ensure you don't scorch the chocolate. Once chocolate is melted, remove bowl from the microwave and stir in the sugar and vanilla extract. Once mixture is cool enough, add the eggs one at a time, beating into the batter completely before adding the next egg. Stir in the flour until incorporated. Pour brownie batter over the peanut butter cookie dough and Nutter Butters until bottom layers are completely covered by the brownie batter.


Bake in 350-degree oven for 35-45 minutes or until a toothpick inserted in the middle comes out without raw batter on it. Do not overbake. It's better to take the bars out and be a little underdone because they will continue to bake in the pan while they set and cool.


Let bars cool completely before cutting into desired sized squares.


Store at room temperature in an airtight container.

Another reason why these are prefect for Valentine’s Day?  Wellllll because calories don’t count on Valentine’s Day!  Yay!

And for anyone who doesn’t want to bake all of that from scratch?  Go to the store, buy pre-made refrigerated peanut butter cookie dough (large or family size) and a boxed brownie mix (large or family size—one that is made to be baked in a 9×13-inch pan).  Press the cookie dough in the prepared baking pan, press the Nutter Butters into the raw dough, make the brownie batter according to the directions on the back of the box, and then pour the raw brownie batter over the raw dough and cookies.  Bake in 350-degree oven for 35-minutes or until a toothpick inserted in the middle comes out without raw batter on it.  Baking times will vary depending on the amount of cookie dough and brownie batter you have.
