When I said I had been on a s’mores wavelength lately, I wasn’t kidding.  Combine that with my exuberant celebration of National Ice Cream Month and this is what you get: s’mores ice cream cake.  Last summer I made toasted marshmallow milkshake shooters for our ice cream social, and I was amazed at how well the flavor of the toasted marshmallow came through.  It’s been lurking in the back of my mind ever since, waiting for another opportunity to use the same technique in something awesome.  Here it is.

I layered homemade graham crackers with toasted marshmallow ice cream, and added hot fudge sauce for the chocolate component.  Once turned out of the pan, a simple topping of torched marshmallows finished it off.  Even though it looks fancy and complicated, all it really requires is a bit of patience during assembly to allow each layer to set.  I found a nice rhythm with mine:  Make the first layer and work out while it sets.  Make the second layer, shower and get ready while it chills.  Add the final layer and put your feet up for a second.  Then jump up immediately because the toddler is trying to eat the cat food again.  No, just me?

  • Yield about 16 servings


For the ice cream:

  • 1½ cups heavy cream, divided
  • 1½ cups whole milk, divided
  • ¼ cup sugar
  • 9 oz. jumbo marshmallows, toasted and allowed to cool slightly

To assemble:

  • 3 9 x 5-inch graham cracker slabs*
  • 1½ cups hot fudge sauce, divided
  • Additional marshmallows, garnish


  • 01

    To make the ice cream, combine ¾ cup of the cream and ¾ cup of the milk in a small saucepan with the sugar.  Heat over medium, stirring occasionally, until the sugar is fully dissolved.  Add the mixture to a blender with the remaining ¾ cup cream, ¾ cup milk, and the toasted marshmallows.  Puree until the mixture is smooth, about 30-60 seconds.  Cover and refrigerate until well chilled.

  • 02

    Freeze the marshmallow ice cream base in an ice cream maker according to the manufacturer’s instructions.  (If the mixture seems too thick to pour into the ice cream maker, blend it once more briefly to smooth it out.)  Transfer to a storage container and freeze at least 1-2 hours to firm before proceeding with assembly of the cake.

    To assemble the cake, line a 9 x 5-inch loaf pan with plastic wrap.  Place one of the graham cracker slabs in the bottom of the pan.  Add about one third of the toasted marshmallow ice cream to the pan and smooth into an even layer with a small offset spatula.  Top with ½ cup of the hot fudge sauce and smooth to completely cover the ice cream.  Transfer the pan to the freezer and let set at least 30 minutes before proceeding with the next layer.  Repeat this same order two more times (graham cracker, ice cream, hot fudge sauce.)  Once all the layers have been added, let chill thoroughly, at least 4 hours.

    When ready to serve, turn the cake out of the pan and peel away the plastic wrap.  Top with additional marshmallows, if desired, and use a kitchen torch to brown them.  Use a serrated knife to slice the cake.

    *You certainly don’t have to make your own graham crackers for this, but I promise it’s worth the effort.  I found a half batch of this graham cracker dough to be just about right for the three layers needed here.  If the shapes aren’t perfect rectangles or are a bit too big for the pan, don’t worry.  Just cut them down to the appropriate size a few minutes after they come out of the oven.

    If you choose to use premade graham crackers, just layer them in a manner to create a complete, even layer as indicated in the recipe.
