How to Make S’mores Bars

Ingredients

To make S’mores Bars, you’ll need:

  • butter – softened to room temperature
  • peanut butter – use creamy peanut butter
  • dark brown sugar
  • sugar – granulated sugar
  • eggs – use large eggs
  • vanilla extract – I love to use my homemade vanilla extract, but if using store-bought, be sure to use the highest quality you can. I donโ€™t recommend using imitation vanilla flavoring as I believe it can leave a bitter aftertaste.
  • flour – use all-purpose flour
  • baking powder
  • salt – a little salt in sweet recipes helps to balance the sweetness
  • chocolate bars – use your favorite quality milk chocolate bars in extra large size
  • graham crackers
  • miniature marshmallows

Step-by-Step Instructions

Make the batter. Cream together the softened butter, peanut butter, and sugars with an electric mixer until well combined and fluffy. Add the eggs one at a time, beating well after each egg, followed by the vanilla extract. Stir in the flour, baking powder, and salt until well combined.

Prep the Baking Dish. Line a 9×13 baking dish with parchment paper that has been lightly sprayed with nonstick baking spray or has been buttered. The parchment paper lining is important – do not skip this step. Then, press 1/2 of the batter into the bottom of the baking dish.

Add the grahams. Arrange a single layer of graham crackers on top of the batter.

Layer with chocolate bars. Top the graham crackers with your chocolate. I used the extra-large milk chocolate bars. I tested the recipe with chocolate chips, chocolate chunks, and thicker pieces of chocolate and did not like the texture or flavor. After testing many of the other types of chocolate, we found the milk chocolate bars were, without a doubt, our favorite.

Layer on the marshmallows. Pour a whole bag of mini marshmallows on top of your chocolate layer.

Spoon on the remaining batter. Then, add the remaining batter in dollops on top of the marshmallows.

Bake. Bake your s’mores bars until done – about 30 minutes.

Let the bars cool and set. Allow the bars to cool completely so that the marshmallows and the chocolate set. I find that I get the best results by baking and allowing them to cool overnight.

Cut and serve. Using the edges of the parchment, lift your s’mores bars out of the baking dish and cut them into individual pieces. You can cut them as large or as small as you like to serve them. Most often, I like to cut them into smaller pieces than shown in the photo so that I have 24 individual pieces.

Make Ahead and Storage Instructions

Place completely cooled bars in an airtight container and store them on the countertop for 3 to 5 days.

I do not recommend freezing because the bars contain marshmallows.

    What size baking pan for the Smores Bars?

    1. Robyn Stone says:

      You should use a 9×13 baking pan, Brooke. I hope you enjoy the bars.

  2. Pet says:

    5 stars
    Hi, im from NZ and haven’t come across Graeme Crackers. Can I use another Plain Cracker…We call them Biscults…. Instead of Graeme Crackers? And do they have yo be unsweetened.

    1. Robyn Stone says:

      The graham crackers are sweetened, Pet. They are made with graham flour. I’m not sure which biscuits you have in New Zealand that would be similar to the ones we have here. You might try one of those. I’m sorry I couldn’t give you more help.

  3. Kelly Hughes says:

    Perfect timing for this to be in my inbox. A weekend with middle & high school students fall retreat. We were going to do traditional smores but there is a ban burn where I live, so no campfire:( This is the next best thing, and a perfect answer to the alternative and can make ahead. THANK YOU!!

    1. Robyn Stone says:

      I’m so glad this recipe was posted just as you need it. Have fun on the retreat! Hope all the kids love it since they can’t do traditional S’mores. Thanks, Kelly.

  4. Gesiena M Petitt says:

    I will make these the next meeting I go to. They sound wonderful

    1. Robyn Stone says:

      I think you and everyone at the meeting will love them, Gesiena. Thanks!

  5. Mindy says:

    I send care packages to my college age son who in turn shares with his friends. He has one friend with a peanut allergy. What can I substitute the PB with?

    1. Robyn Stone says:

      Mindy, you can substitute the peanut butter with the same amount of butter. If he is only allergic to peanuts and not other nuts, you could try other nut butters such as Nutella, almond butter, etc. I would make sure that the nut butters were not processed in same plant that processes peanut butter. It should be on the label of the nut butter.
