Strawberry S'mores Icebox Cake

4.5 from 2 votes
Easy to make no bake cake with three layers of whipped cream, marshmallows and Fluff, graham crackers, sweet strawberries, and rich chocolate ganache. Perfect to make ahead for a summer party - and you can even swap homemade whipped cream for Cool Whip to make it even quicker!
Prep Time 15 minutes
Total Time 4 hours 15 minutes
Servings 9 slices


  • 4 ounces mascarpone cheese, I use Belgioioso
  • ¼ cup sugar
  • ¼ teaspoon vanilla extract
  • 1 cup heavy cream
  • 12 ounces semisweet or dark chocolate chips or chopped chocolate
  • 12 ounces heavy cream
  • 1 cup marshmallow Fluff
  • 2 cups mini marshmallows
  • 12-15 graham crackers
  • 3 cups fresh strawberries, sliced and divided
  • Optional: additional mini marshmallows, crushed graham crackers and chocolate ganache for topping



  • Chill a large mixing bowl in the fridge - you'll need this for the whipped cream. If you're not going to make your own whipped cream and would prefer to use premade or Cool Whip, you can skip this step.
  • Remove stems from the strawberries and slice. Pro tip: if you have an egg slicer, use it to slice the strawberries and speed up the process!

Make the ganache:

  • Place the chocolate in a heatproof bowl.
  • In a small saucepan, warm the heavy cream over low heat until it comes to a simmer.
  • Immediately pour the cream over the chocolate, and let it sit for a few minutes. Stir until melted, combined and smooth.
  • Place the chocolate in the fridge while you prep the rest.

Make the whipped cream:

  • Note: If you're not going to make your own whipped cream and would prefer to use premade or Cool Whip, you can skip this step.
  • In your chilled bowl, combine mascarpone cheese and sugar on a high speed until completely combined.
  • Add vanilla and heavy cream, and mix on a low setting until it is mostly combined. Now increase speed to high and whip until stiff peaks form. Set aside.


  • In a large bowl, add ⅔ of the prepared whipped cream (or Cool Whip, if using), Fluff and mini marshmallows. Use a spoon or spatula to stir to combine.
  • In an 8x8 pan, spread a thin layer of the marshmallow mixture on the bottom of the pan. You just want enough for the next layer of graham crackers to stick.
  • Line the bottom of the pan with a single layer of graham crackers, breaking them as needed to cover everything.
  • Use a spatula to spread ½ of the remaining marshmallow mixture on top.
  • Add a layer of sliced strawberries.
  • Pour half of the chocolate ganache on top, using a spatula to smooth it out.
  • Now start over! Add another layer of graham crackers, the other half of the marshmallow mixture, then another layer of strawberries, and top with the remaining chocolate ganache.
  • Top with one more layer of graham crackers and cover with the reserved ⅓ of your whipped cream and the remaining strawberries.
  • Optional, but strongly encouraged: Add a handful of mini marshmallows, crushed graham crackers and a hearty drizzle of melted chocolate to top it all off!
  • Place in the fridge for at least four hours to let it all meld together. Slice into 9 pieces, serve and enjoy!
