S’mores Cookie Cake

S’mores remind me of our idyllic family vacations to Aspen, Colorado each summer. We’d take killer hikes, window shop all the exclusive boutiques, sit in the grass outside the Aspen Music Festival tent listening to practice, and we’d picnic along the Roaring Fork River.

The kids were in charge of finding kindling and my dad would start a crackling campfire. We’d grill brats, munch on chips, and eagerly await the next course. The scent of a pine forest still evokes memories of our meals at Maroon Lake with the breathtaking Bells in the background or the Grottos along Independence Pass. And also of those s’mores we toasted for dessert. It’s not a surprise my family was gung-ho for this S’mores Cookie Cake.

Summer S’mores Desserts

Fast forward to 2012 where S’mores bars and cookies are de rigueur. I decided to go one step further and make a cookie cake. I took the base I’ve used for S’mores cookies, baked it, topped it with milk chocolate ganache, followed by mini marshmallows which were browned with the broiler.

Even Katie, the pickiest family member loved this s’mores dessert recipe. So for your summer picnic, take along the epitome of the American dessert, a S’mores Cookie Cake. And when that disappears, this Easy S’mores Dessert Dip  and S’mores Cookies are more family favorites!

Tips for Making a S’mores Dessert

As you probably know, the classic campfire s’mores recipe is composed of graham crackers, a milk chocolate bar and a toasted marshmallow. Any s’mores dessert recipe needs to have that trio of ingredients.

  • For s’mores cookies or cookie cake, adding graham cracker crumb to modify a chocolate chip cookie dough is an easy way to add the graham cracker component.
  • Regular or mini chocolate chips and/or chocolate ganache provide the necessary chocolate.
  • Any sized marshmallows or marshmallow cream can be utilized for the marshmallow component.
  • PRO-Tip: If using marshmallow creme, spray your spoon with non-stick cooking spray to minimize sticking.
  • Dolloping sticky marshmallow cream on top of s’mores bars or a layer of marshmallows is much easier than making marshmallows from scratch.
  • If you’ve never made marshmallows from scratch, they’re a simple concoction of hot sugar syrup and gelatin. They’re best made in a stand mixer. Flavored with pure vanilla extract and dusted with powdered sugar, the taste is superior to anything you could buy.
