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 sโ€™mores bars can be stored wrapped in foil or in an airtight container at room temperature for up to 4 days.
How to Freeze:

    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.

    1. Sandy says:

      I’m adding new recipes all the time. I am eating more low carb myself these days and am planning more low carb recipes! Thanks for your comment.

    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.
