let the parchment overlap and hang off the edges for easy remove of the bars from the pan.

assembling smore bars



press the graham crackers into the peanut butter cookie dough so they stick,

then top the graham crackers with the chocolate marshmallow cream, spread it with a small offset spatula until it’s smooth and even.

That way when you cut the bars, they will all look uniform.

The baking starts now,

bake for 15 minutes.

toasting marshmallows in oven for smore bars


Toasting the marshmallows if the final step, but please don’t start doing something else. This is the critical part that you will want to watch them carefully.

As the marshmallows heat they will swell and then start turning golden brown. Take them out of the oven, as soon as they are all golden. If you leave them in too long, they will burn and become messy and sticky and difficult to cut. So for the bars to be easy to cut when they cool, look for that golden color.

If at 350 degrees after two minutes, the marshmallows don’t turn golden, turn the broiler on high and place the baking pan in the middle of the oven, so that the heat browns them without having them too close or burning the marshmallows. This will only take a minute.

S’more Peanut Butter Bars
  • 9 (twin) graham crackers (these will fill one layer in an 8×8 pan
  • 1-2 package marshmallows (36 for top of S’mores) 18 for marshmallow cream
  • 2 tablespoons butter
  • 3.5 oz dark chocolate
  1. With the peanut butter cookie dough pressed into the 8×8 pan (see above recipe for details)
  2. press the graham crackers into the cookie dough
  3. remove 36 marshmallows from the bag and reserve these for the top of the bars.
  4. In medium saucepan over medium heat mix marshmallows (about 28 marshmallows)
  5. with two tablespoon butter
  6. then add in 3.5 oz dark chocolate cut into small pieces so it melts easily
  7. Once the chocolate marshmallow cream is smooth, remove pan from stove.
  8. Pour mixture over graham crackers and spread with a small offset spatula so it’s even in the pan.
  9. Bake at 35 degrees for 15 minutes.
  10. Place the marshmallows with the flat side down on top of the chocolate marshmallow cream mixture.
  11. Place in the oven for two minutes, then turn the broiler on high and place the pan on the middle rack and watch carefully as the marshmallows turn a light golden color.
  12. *if the marshmallows cook too long they will melt a lot and they will be more difficult to cut and the result will be messier and stickier.
  13. Remove pan from oven.
  14. allow the bars to cool for 20 minutes
  15. left out the parchment paper so the bars come out smoothly
  16. Place the bars with parchment paper on a cooling rack, and let them cool another 5 minutes.
  17. Cut the bars into pieces.
  18. I found it easiest to cut in between the marshmallows, So some bars are 4 marshmallows on top, two on top, one on top for bite sized portions.








    1. On the counter the day they are made. Then you can put them in the fridge, as with any baked marshmallow item, I think they are best consumed closest to making them. (that day, the next day) marshmallows get dry and they are not as appealing to me. You can always pre bake the cookie part one day if you want to do the final steps before serving the day of.

  1. Are these miniature or regular marshmallows? The regular bag is only 36 so there would be no extras for the cream. These look delicious and I don’t want to mess them up! Thank you for the recipe.

    1. I may have had a brand that had more marshmallows than 36. I went to check my notes and it looks like 18 for the marshmallow cream and 36 for the top. So I adjusted the ingredient list to call for 1-2 bags (maybe all won’t be used) and adjusted it to give a more specific amount of marshmallow count.
      Happy Baking!
