Keto Smores Bars are the best dessert for a low-carb diet during summer. They are made with a keto graham cracker crust, a layer of melted sugar-free chocolate, and sugar free marshmallows. This classic camping treat is gluten-free and a delicious substitution for regular carb-heavy s'mores.

These smores bars are filled with gooey deliciousness of chocolate and marshmallows just like keto smores and keto smores bites. two smores bars stacked on top of each other with chocolate chips scattered You won’t need a campfire to cook up these s’mores!

Substitutions

These low-carb chocolate bars are easily adjustable to fit your tastes and preferences. Here are some options you can try:
  • Graham cracker crust: For a shortcut to making your own honey graham crackers, use this keto honey graham cereal by Catalina Crunch. It’s similar to golden graham cereal but without the sugar or carbs. Grind the cereal in a food processor and mix with melted butter. Layer onto a baking sheet lined with a piece of parchment paper and freeze to cool.
  • Chocolate: If you don’t have access to keto chocolate or sugar-free chocolate chips, just use 85-90% dark chocolate since it has the least amount of sugar.

  1. These bars turned out great. I used the vanilla instead of graham cracker flavoring and it still had a nice, familiar taste. Do you think these would hold up if kept at room temperature during a picnic?

  2. These were easy to make and turned out great. I’ve been on keto a few months and this is the first recipe that really captured that nostalgic s’mores flavor. Will definitely make again for summer gatherings.

  3. These turned out perfectly! I’ve really missed s’mores, this definitely hit the spot without kicking me out of ketosis.
