Thanks to my friend Chef Alli for sharing this easy recipe that makes a big smore bar in the form of a cake. Since this dessert is so visually attractive and unique it makes a special birthday cake, especially for people who love camping.

My family’s favorite part of this Smores Cake is the THICK layer of chocolate.  Four Hershey’s 4.4 oz chocolate bars fit almost perfectly in the pan.  Each time we’ve made this cake we had a couple extra pieces of chocolate that we had to figure out what to do with.  So in our minds, the XL Hershey bars are a perfect fit in a 9×13″ dish because we get a couple pieces to snack on while the cake bakes.

Why This Recipe Works:

  • I can definitely make both of these recipes much more quickly than I can build a fire to make a smore!
  • The pieces of cake can be cut into squares to look like real smores and the taste is amazing too.
  • This recipe is easy to make, but will be a stand out on any dessert table to share with friends.
  • Simple ingredients make a unique cake that people often ask for the recipe.

Ingredients Needed:

  • Graham Cracker Crumbs – I like to purchase a canister of crushed crumbs, but you can use a bag to crush whole graham crackers too.
  • Flour, Sugar & Salt – Give more substance and sweetness to the crust.
  • Eggs, Butter & Vanilla – Add some richness to the crust and help the crust hold together and become golden brown while baking.
  • Hershey’s Chocolate Bars – Use 4 of the XL bars that are 4.4 ounces each for a total of 17.6 ounces of chocolate to make a thick layer.
  • Marshmallow Fluff – comes in a big container, but two smaller containers of marshmallow creme work fine too. I like to use a silicone spatula to minimize sticking of the fluff.
Ingredients to make smores cake on a brown wooden counter top are Hersheys milk chocolate bars, marshmallow fluff, eggs, butter, brown sugar, salt, flour, sugar, vanilla and graham cracker crumbs

Step By Step Instructions

Spray a 9 x 13 baking dish with non-stick cooking spray to 350°F.

Melt the butter, crack eggs and add to a mixing bowl. Mix together.

Measure out dry ingredients and stir together.

Slowly add dry ingredients to the eggs and butter and mix well.

Mixer stirring up the s'mores cake batter

Spread half of the cake batter in the bottom of greased baking dish. 

Add a layer of chocolate bars.  Leave three bars whole, do not break them into pieces as they will fit easily in the pan.

Push the bars together so there is no space between the candy bars.

Take the final chocolate bar and break into pieces or place on a cutting board and use a butter knife to help divide.

The pieces may not have perfectly straight lines and that is okay. Fit them as flat and tightly as possible.

Then layer with a large container of marshmallow fluff.

Top with remaining dough and bake.  This step will take a bit more time to flaten each piece of graham crack batter by hand and arrange as evenly as possible over the top.

I begin by making as big of pieces as I can to provide the most coverage.

Then I go back with smaller pieces to fill in the gaps.

If you want every square of smores to be perfectly uniform then make sure each of the ingredients is spread evenly edge to edge.

Bake uncovered until lightly golden brown on top. The marshmallow creme will bubble up and the cake has a beautifully unique look.

Recipe Tips & Tricks

  • This cake freezes really well in individual pieces. Set one or two pieces out on the counter for a couple hours and it will taste amazing!
  • Sometimes it can be difficult to find the thicker XL Hershey bars that are 4.4 ounces each – as long as you make two layers of thinner bars the cake will still be great.

  1. I made these as a 4th of July dessert and it was loved by everyone! I didn’t have marshmallow fluff so I used mini marshmallows which turned out great too. Thanks for a great recipe! I will be making this again in the near future.

    1. So glad to hear this! Thanks for letting me know!

  2. Can I make this the night before? Should I do everything up until baking and keep in fridge or will it be ok cold?

    1. Hey! Great question! This cake can definitely be made a day ahead of time. We have left it out on the counter for 2-3 days before, but putting it in the refrigerator is a great idea too. Hope you enjoy!

    Made it for desert, really rich. I used the large marshmallows as that’s what I had on hand and turned out good.

  5. 5 stars
    Made this today and my boys loved it! Thanks for posting.

  6. 3 stars
    Too salty. Also the batter did not make a 9×11. I used and 8×10. Taking it to a party tonight, so we shall see what they say. Because it is so rich, I plan to cut it into 1″ bars. I think this cake should cool for 20 minutes before cutting into it.
