White Chocolate Macadamia Cookie Cake with Peanut Butter Frosting

I cannot for the life of me get these cookies off my mind.

Our last tryst involved a very long road trip with some very hungry besties, and once you’ve had a warm and chewy this-may-have-spent-a-little-too-much-time-in-the-car cookie for breakfast, there’s no coming back from that. I may have joked that I was going to bake them into one giant cookie and use it as a pillow.

How could I not follow through on that?

I may have died and gone to peanut butter heaven with this one. Each slice is a medley of warm, gooey, soft, chewy, melty amazingness with a nice crisp edge and crackle at the top. If that wasn’t enough of an adjective bomb for you, then you’re as insane as I am.

Call me cuckoo for coca puffs all you’d like, but I make a mean cookie cake.

That reason alone should solidify my VIP status at any and all birthday parties from now until forever. Granted now that I’m a mom some of those parties may be kiddie parties.

Those things have booze, right? If not, then this momma is spiking the OJ!

And with that, I give you cake:

Author Jenn Laughlin - Peas and Crayons


  • 3/4 cup unsalted butter (softened)
  • 3/4 cup light brown sugar
  • 1/4 cup granulated sugar
  • 1 large egg (room temperature)
  • 2 tsp pure vanilla extract
  • 2 cups all-purpose flour
  • 2 tsp cornstarch
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 3/4 cup peanut butter chips
  • 1/4 cup macadamia nuts (halved or chopped)
  • 2 oz quality white chocolate (cut into chunks)


  • 1/4 cup salted butter (softened)
  • 1/4 cup peanut butter
  • 1.5 cups powdered sugar
  • 1/4 cup milk (cow, coconut, and almond all work)


  1. In a large bowl, cream together softened butter and sugar with an electric hand mixer. Start at the lowest speed and increase as needed.
  2. Add in the egg and vanilla and continue to beat with the mixer to incorporate.
  3. In a seperate bowl, mix together flour, cornstarch, baking soda, and salt.
  4. Add flour mixture to the larger bowl slowly while you continue to beat on low.
  5. Once your dough is mixed, fold in peanut butter chips, macadamia nuts, and chopped white chocolate and cover.
  6. Next pop it in the fridge for an hour, or overnight. Whatever works for you!
  7. Ready to bake?
  8. Pre-heat your oven to 350F then grab your dough from the fridge.
  9. Place a sheet of parchment paper on the bottom portion of an un-greased 9-inch nonstick springform pan and lock in the sides.

  10. Press in your dough and bake on the center rack for 18-22 minutes. Mine is nearly always done in 20 but oven times may vary a smidge based on oven temperament as well as the size pan you used for the cookie. A thinner cake will finish a teeny bit faster than a thicker one, you know the drill!
  11. Once your cookie cake has finished baking, flip your oven to broil on HIGH and watch it like a hawk. After about a minute the top will brown to golden perfection, still leaving that soft slightly cookie dough-esque center intact.
  12. While your cake cools, whip up the frosting using a handheld electric beater. The thickness and sweetness can be adjusted to taste by beating in extra powdered sugar at the end, if desired, but the ratio above was my version of peanut butter perfection!
  13. Once your cake has cooled, use a piping bag or a trusty ziploc with the corner cut off to fancify your cake with a little bit of melt-in-your-mouth peanut butter frosting.

Recipe Notes

Recipe will yield best results when dough is refrigerated before baking. I typically make mine ahead of time and leave it in the fridge overnight.

In a rush to cake it up? Pop it in the fridge for an hour before baking instead! 24 hours of chill time is typically ideal with cookie dough, but even when I rush the results are still scrumptious!

Not a fan of nuts? Sub for extra white chocolate and get this cake in your face, stat!

For this recipe I use a 9-inch non-stick springform pan. A 10 or 11- inch non-stick springform will also work great too. Basically the larger the pan you use, the thinner the cookie cake will get so if you like a thicker cookie cake with a soft center, aim to use a pan around 9-10 inches in diameter.

Dive in with a fork if you’re feeling civilized…


…but fastest cake to face physics involves manhandling each slice like you’re eating pizza.

I don’t have a photo of the latter.

I was too busy flinging my camera aside and diving faster than Cookie Monster coming off a juice cleanse.

Or maybe Pac-Man after a ghost-chugging bender?

I have issues. I’m okay with that.

      Do. Not. Wait…. make this NOW! Hands down one of the yummiest cookie cakes EVER! Added a scoop of vanilla ice cream and my guests went nuts for it. Had to hide the last piece for myself. Thanks for this heavenly desert ❤

  • WOW this looks amazing!!

  • Good god woman! You have outdone yourself.

  • If your issues involve cookie cake feel free to invite me along for the ride… I’ll even bring you a peanut butter pillow 🙂

  • Oh my. Did I mention it’s my birthday? In a little over three months from now at least. And I don’t mind cake deliveries. Or alternatively invitations to any birthdays taking place at your house. No matter if adult or kiddie parties. I might actually prefer the latter because they mean no side glances when I eat cake with my hands, Forks are overrated, right?!

  • oh my gosh. This is so creative and delicious!

  • jillian

    omg yessss this sounds amazing! xo jillian

  • I just might have to make this dessert this weekend!

  • I saw this on instagram and thought it was a dream.

    You have just made the term ‘dreams come true’ stand true.

    After you open up your pizza joint, you will make cookie pillows.

    This cookie cake is fabulous! This cookie cake is so thick and rich that I couldn’t believe it needed frosting. But the peanut butter frosting was a surprisingly good addition! It just made the cookie more delicious!

  • Ummm….this looks incredible. Not sure how you got those pictures taken at all! Dangerous.

  • This looks and sounds amazing, yum!
