Tips & Variations for Making S'mores Bars

  • Graham Cracker Crust: Try chocolate graham crackers instead of regular graham crackers. Teddy Grahams, both chocolate and regular, make for a nice crust, as do Oreos, gingersnaps, Biscoff cookies, and Golden Grahams cereal.
  • Chocolate Layer: Try dark chocolate, milk chocolate, semi-sweet chocolate chips. Peanut butter or butterscotch chips are also delicious. Or try chocolate candy bars such as the classic Hershey's (you'll need about 6 XL size).
  • Marshmallow Layer: Instead of mini marshmallows, you can add an even layer of marshmallow creme on top of the chocolate chips.
  • Nuts: Add in chopped nuts, such as pistachios, almonds, peanuts, or pecans.
  • Cutting Into Squares: Use a large knife such as a chef'e knife to cut them. You can make the bars any size you like.

How to Store

Leftovers s’mores bars can be stored wrapped in foil or in an airtight container at room temperature for up to 4 days.
How to Freeze:
The bars can be placed in a freezer-safe container or in a freezer ziplock bag and stored in the freezer for up to 3 months. Thaw the bars overnight in the fridge and then bring to room temperature, or you can warm them up in the microwave for 10-15 seconds before enjoying.

Ingredients
  • 2 sleeves Graham Crackers (~2 ½ cups crushed)
  • 1 ½ sticks Unsalted Butter (12 Tbsp. melted)
  • ¼ cup Granulated Sugar
  • 1 (12-ounce) bag Mini Marshmallows
  • 12 ounces Semi Sweet Chocolate Chips*
Instructions

  2. Prepare a 9x13-inch baking dish by lining the dish with parchment paper (or foil). Spray the parchment paper with cooking spray and set aside.

  5. Add the crushed graham crackers and sugar to a large bowl. Stir in the melted butter. Mix until fully combined and all of the crumbs are coated in the butter.

    Oh my goodness these sound so good. I wish I could eat them but I'm diabetic. It would be a blessing if you could have more low-carb recipes. Less, pasta, rice, and potatoes would help. I do love your recipes that I can have. Coq au vin was fantastic. Love the crockpot recipes.

    Hello Sandy;
    I've been following you for years and have made quite a few of your recipes. I have a request. Could you possibly include Nutritional information?
    I have diabetes and have to count calories and most especially carbohydrates on everything I eat. The carb count is what I use to figure how much insulin I need to take.
    That is very time consuming. If I just had info on those two things it would be so much help.
