Rocky Road Cookie Cake Recipe

This baby was described by one of my taste testers as “change your life good.” Oh yea!

So this past Sunday I hosted a baby shower for one of the women in my small group. All of our baby showers (3 now) have been couple showers, so we avoid things like decorating onesies and opt for guessing the price of baby stuff kind of games so that the guys can get into it – at least a little.

This past Sunday actually involved some football watching as well, given the time of day on Sunday. Not your usual baby shower, huh? 🙂

It was a great success! The wonderful thing about our small group is that even though I’ve hosted all three baby showers so far, I don’t actually have to do that much work. It’s totally a team effort.

I’m obviously the designated cake maker. And I usually help with decor because I like that kind of thing. But most everything else, like food and the main decor stuff, is taken care of by the other couples. We all kind of have our “thing” figured out. Then everyone but the parents-to-be show up early and throw everything together real quick. After this third one, we definitely have it down to an art.

The theme was Pioneer Woman this time around because the mom-to-be is a huge fan. She has her cookbooks and I’m sure some other stuff and it was a totally fun theme to put together. Most of the food was made from recipes on her blog, including this amazing Chocolate Strawberry Nutella Cake that I made. Check out the photo of the food and table set up.

One of the girls in our group even got a children’s book written by Ree herself as the guest book for everyone to sign. How stinking cute is that?! Good times were had by all.

This Rocky Road Cookie Cake will also guarantee a good time for all. It was a massive hit with myself and my taste testers. Seriously delicious! The stuff dreams are made of.

How to Make This Chocolatey Cookie Cake

Making it is pretty straightforward. Once you’ve made the cookie dough, which is stuffed with nuts and chocolate chips, you’ll press half of it into your cake pan. You’ll top the dough with marshmallow fluff – the good stuff. This stuff is gooey-city. And it works better than actual marshmallows when this cookie is baked because marshmallows melt and disappear.

Top the fluff off with the rest of the cookie dough and bake.

The cookie will still be a little jiggly in the center when it’s done baking. It will continue to bake a little and firm up as it cools. I let it cool completely in the pan, shaking it around a few times as it cools, so that it doesn’t stick to the pan.

Once cool, remove it from the pan. When ready to serve, toss on some more chocolate chips, marshmallows and nuts. Warm it up and toast the marshmallows a bit by putting it in the oven on convection bake for about 15 minutes. The cookie won’t cook any more, but it will get warm and gooey on top and in the center, where the fluff is.

This is the good stuff, my friends. Warm, gooey, chocolatey. Don’t miss out, because that would be a shame.

This Rocky Road Cookie Cake is everything you could want out of a cookie cake. It’s soft, chewy and oh-so-gooey! A chocolate cookie stuffed with chocolate chips, nuts & marshmallow fluff, then topped with more chocolate chips, nuts and marshmallows!



  • 3/4 cup salted butter, room temperature
  • 1/2 cup brown sugar, lightly packed
  • 1/2 cup sugar
  • 1 egg
  • 1 tsp vanilla extract
  • 1 1/4 cups all purpose flour
  • 1/2 cup cocoa (I use Hershey’s Special Dark)
  • 1 tsp baking soda
  • 1 1/2 cups chocolate chunks or chocolate chips
  • 1/2 cup chopped nuts, optional (I used pecans)
  • 3/4 cup marshmallow fluff


  • 1/41/2 cup marshmallows
  • 1/4 cup chocolate chips
  • additional chopped nuts


1. Preheat oven to 350 degrees and prepare a 9 or 10 inch cake pan by placing parchment paper in the bottom of the pan and spraying the sides with a non stick spray.
2. Cream butter and sugars together until light and fluffy, about 3-4 minutes.
3. Mix in egg and vanilla extract.
4. Add flour, cocoa and baking soda and mix until combined.
5. Stir in chocolate chunks and nuts. Dough will be thick.
6. Spread half of the dough evenly into the cake pan.
7. Spread marshmallow fluff on top of cookie dough.
8. Drop remaining cookie dough over the marshmallow fluff and flatten into an even layer.
9. Bake for 18-20 minutes. The center may still look a little undercooked but it will firm up and continue cooking as it cools.
10. Remove from oven and let cool completely in pan, then carefully remove.
11. When ready to serve, top cookie with marshmallows, chocolate chips and nuts and bake on convection bake for about 15 minutes, until marshmallows are lightly toasted.
12. Allow to cool for about 10 minutes, then serve.

    Could I use your triple chocolate cookie recipe and then follow the instructions above for the marshmallow fluff?
    Also would it work halfing the recipe and putting it in a 6 inch cake pan?

  2. Stefanie C.

    For the cookie cake, can I use a chocolate cake or brownie BOXED mix? Also, can I bake in a pie pan? Thanks!

  3. Czarlie Mae dela Cruz

    Hello there! I have a question about the temperature of all your recipes, is it in fahrenheit or celsius?

  4. Kaylene Fullmer

    My oven doesn’t have just a convection setting. Would I put it to the lowest setting (warm), or can I put it under the broiler to toast the marshmellows on top?

    Hi! This cake looks really delicious and amaze!!! I really want to make this for my sisters b-day this weekend but i have to make it maybe an hour or two before hand so i was wondering if anyone knew how long this cake can be stored for and where it should be stored? Thanks!:)


      You can definitely make it ahead of time. The cookie would even be fine a day ahead. You’ll just want to store it in an air-tight container. I’d recommend adding the toppings to the cookie shortly before serving if you can so that it’s warm, but if not, it’ll be good cooled as well.

    Such a cute idea for a baby shower especially the guest book! I didn’t even know Ree had written a children’s book! This cake looks amazing and I am sure the plate was licked clean…or at least it would have if I had been there! 😉

  7. Julianne @ BeyondFrosting

    Sounds like your baby shower went well! I love the PW thing! But this cookie cake, OMG! Gorg.

  8. Michelle @ My California Kitchen

    I think I need a glass of milk just looking at this amazing cake!! Love that you used special dark cocoa! My favorite!

  9. Kathi+@+Deliciously+Yum!

    I am not sure if I should trust my eyes or not… because what I’m seeing almost looks to good to be true. I am dying to get my hands on a slice. Fabulous , Lindsay!
