Have you ever wondered if there was a way to make low-carb S'more's bars? They are a decadent soft and gooey dessert, and it's hard not to miss them when you go keto.

These S'mores Bars are the perfect bite-sized treat for your holiday and New Year's Eve table!

At first "ketofying" S'mores Bars seemed like and impossible task. Luckily, with the right type of sweeteners and healthier grain-free flour alternatives, you can make almost any of your favourite treats keto-approved!

Keto S'mores Bars do take extra time to prepare as you'll need to make a batch of our No Fail Fluffy Keto Marshmallows and a batch of Homemade Low-Carb Graham Crackers.

In this recipe I first baked the crackers and then topped them with chocolate and marshmallows. Finally I blow torched each bar and topped with another cracker. This isn't he usual way to make S'mores Bars but I think it makes them look prettier, especially if you want to make these for New Year's Eve.

Traditional Way to Make S'mores Bars

You could follow a more traditional way of making S'mores Bars by placing the raw keto graham cracker dough in a tray, layer dark chocolate on top, followed by a layer of sugar-free marshmallow fluff (you could use it straight from the mixer), and finally finished with another layer of raw keto graham cracker dough. You can then bake it at 170 °C/ 340 °F (fan assisted), or 190 °C/ 375 °F (conventional) for 15-20 minutes. They won't be as pretty but will be just as delicious.

I hope you enjoy. Happy New Year to all of you!

Ingredients (makes 20 servings)

Graham crackers:
To assemble:


  1. Prepare the the full No Fail Fluffy Keto Marshmallows recipe. To do that you'll need water, gelatin powder, Allulose (or other low-carb sweetener such as Erythritol or Swerve), vanilla extract and salt.
  2. Cut the marshmallows into 20 smaller cubes. (The original recipe asks you to cut in 15 but you'll need smaller marshmallows in this recipe.) Keto S'mores Bars
  3. Prepare the Homemade Low-Carb Graham Crackers. To do that you'll need butter, Erythritol (or Swerve), almond flour, flax meal, cinnamon, baking powder, vanilla extract, salt, egg and blackstrap molasses (or use yacon syrup instead). Make sure to cut them in 40 pieces so you have 2 crackers per each bar. Keto S'mores Bars
  4. Place a piece of dark chocolate (Lindt works best as it's large and thin) on top of each cracker. Add a piece of marshmallow
  5. Just before serving, use a blow torch to caramelize. Alternatively, you could broil on high, very briefly. Top the toasted marshmallow with another cracker. Optionally, blow torch the sides.
  6. Once toasted, these S'mores Bars taste best fresh. You can store the individual components for several days. The crackers will keep at room temperature in a container loosely covered with kitchen towel for up to a week. The marshmallows can be stored in an airtight Tupperware, layered between sheets of greaseproof paper, for 2 to 3 weeks. They should be dusted with a mixture of arrowroot and powdered low-carb sweetener as described in the original recipe.) Keto S'mores Bars

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.
