Fudgy S'more Bars with a crispy graham cracker crust are reminiscent of sitting around a campfire toasting marshmallows and eating s'mores.



  • 1/2 cup flour
  • 1 cup graham cracker crumbs (12 squares/6 rectangles)
  • 3/4 cup brown sugar
  • 1/2 teaspoon baking soda
  • 1/2 cup butter, softened



  1. Heat oven to 350 degrees Fahrenheit, Grease 9x13 pan (I used a glass pan). In a large bowl, combine all crust ingredients and mix well until coarse crumbs form. Press into the bottom of a greased pan. Bake at 350 degrees Fahrenheit for 12 minutes.
  2. Remove pan from the oven and sprinkle evenly with marshmallows. Return to the oven and bake an additional 1-2 minutes or until marshmallows are puffy. Remove pan from the oven and sprinkle evenly with M&Ms. Drizzle with chocolate syrup. Let cool 1 hour, or until completely cooled. Cut into bars.


One of the easiest ways to crush graham crackers is to place them in a resealable bag and roll over them with a rolling pin until the graham crackers are crumbs.

I like my marshmallows to be slightly toasted. For this, once your marshmallows are puffy, place them under the broiler for 1-2 minutes at the second or third rack from the top. Watch very closely as they can burn quickly.

Best Method for Cutting S’more Bars

Toasted marshmallows can be quite tricky to cut due to how sticky they are. However, there are some tricks to make it easier. First, you want to make sure the bars have completely cooled.

  • Step 1 – Use a sharp, serrated knife. Oil both sides of the knife lightly with vegetable oil. You may want to wipe gently with a napkin or paper towel to ensure the layer is quite thin as you don’t want to make your bars greasy.
  • Step 2 – Slowly and carefully cut the bars. You will want to cut up and down in one cut, rather than dragging the knife through the bars.
  • Step 3 – Wipe down the knife and add another thin layer of oil as needed to prevent sticking.

Fun Variations

This recipe is great the way it is, but there are some fun variations you can try to mix things up a bit.

  • Try using cinnamon or chocolate-flavored graham crackers.
  • Use different types of M&Ms such as caramel, peanut or fudge brownie
  • Try other candy besides M&Ms or use half M&Ms and half another type of candy. Some other types of candy you might try are mini peanut butter cups or chopped Butter Finger.
  • Substitute chopped cookie pieces for M&Ms, for example chopped Oreo or Chips Ahoy pieces.

Storage and Shelf Life

These bars are definitely best served within 1 day of being made. However, they can be stored for 2-3 days at room temperature or refrigerated. You can freeze these S’more Bars for 2-3 months; make sure to thaw before serving.
