Preparation and cooking overview

To make these S'mores Bars you need to bake the keto graham cracker crust base for 20 minutes, add the chocolate filling, and coat it with marshmallow topping. In 40 minutes total you'll have a perfect treat for your sweet tooth.

Chef's note

One thing to note is that the marshmallows used in this recipe DO NOT char, so you can't use these to make your typically roasted S'mores. Bummer, we know. But they're still divine without being toasted.

Crust⁠

  • 1 ½ cups almond flour⁠
  • ¼ cup Whole Earth Monk Fruit Blend⁠
  • ½ teaspoon cinnamon⁠
  • ½ teaspoon vanilla extract⁠
  • ¼ teaspoon salt⁠
  • 5 tablespoons unsalted butter⁠

Chocolate Filling⁠

Preparation steps

  1. Ensure you have everything you need before cooking and avoid any last-minute trips to the store.
  2. Measure all the ingredients with measuring cups and tools to replicate the recipe.
  3. Preheat the oven to 325°F to prepare it for baking.
  4. Line or grease a 10" cast iron skillet, so make the base non-sticky for the crust.
  5. Ready your food processor, a microwave-safe bowl, a candy thermometer, and a stand mixer.

Cooking instructions

  1. In a food processor, pulse together all the ingredients for the crust until it resembles graham cracker crumbs.
  2. Press the mixture into a lined or greased 10" cast iron skillet.
  3. Transfer the skillet to the oven and bake the crust for 20 minutes. Remove and set aside.⁠
  4. Place the chocolate chips in a microwave-safe bowl for the chocolate ganache filling and pour over the heavy cream. Heat in 30-second intervals, stirring between cycles until the chocolate is melted.

  6. To make the marshmallows, place cold water in a stand mixer and, sprinkle in the gelatin, let bloom for five minutes.
  7. In a medium pot, combine the water and monk fruit blend, and bring to a boil until the temperature reads 230°F on a candy thermometer.
  8. Turn the stand mixer to medium speed and slowly stream in the monk fruit blend mixture. Increase the speed to high for 15 minutes until thick and glossy.
  9. Pour the marshmallow fluff on top of the bar, return the skillet to the refrigerator, and cool for at least one hour.
  10. Carefully slice in the squares to serve. The final result is so delicious we bet you'll love it more!

Chef's pro tip

Keep a close eye on the marshmallow mix while it's getting thick in the mixer. You don't want it to get too beat up and lose its light and airy feel. If it's already got too stiff, throw in a spoonful or two of hot water and give it a gentle stir. This should bring back the fluff. But don't go overboard, or you'll end up with a soupy mess. When it's time to cut the bars, grab a sharp knife 'cause that marshmallow layer can be a really sticky situation and tough to slice neatly.

How to make it healthier?

You can increase the nutritional value of this sweet treat through the following methods:

  • Increase the fiber content: Add ground flaxseed, chia seeds, or psyllium husk powder to the crust or chocolate topping.
  • Use dark chocolate: The recipe calls for sugar-free semi-sweet chocolate chips, but you could also use dark chocolate with a high percentage of cocoa solids as it is a good source of antioxidants.
  • Swap butter for coconut oil: Substitute unsalted butter with coconut oil, as it is rich in healthy fat.

Time-saving tips

  • Buy pre-made almond flour crust. This will save time and also keep your dish keto-friendly.

What can I prepare ahead of time?

  • Gather and measure all the ingredients.
  • Make the crust mixture ahead of time and store it in an airtight container until needed.
  • Create the chocolate filling ahead of time. Keep it refrigerated.

Storage instructions

The Keto Smores Bar Recipe makes the perfect dessert for meal prep. Here are the storage tips:

  • Room temperature: Store the bars in an airtight container. Keep them away from direct sunlight to prevent the chocolate from melting.
  • Refrigerator: For longer storage, keep the bars inside an airtight container in the fridge for up to one week.
  • Freezer: You can freeze the bars for up to three months. Cover the bars in plastic wrap and place them in an airtight container to prevent freezer burn.

Recipe wrap-up and conclusion

Sticking to the keto diet can sometimes feel a bit lonely, especially when you can't share a sweet treat with your buddies or loved ones. But there's a workaround—whip up some Keto S'mores Bars right in your kitchen.

Every keto fan's gotta try this one. This dessert got the perfect mix of a sweet and crunchy base, a layer of melty chocolate, and roasted marshmallows on top. The best thing about it? You can chow down on this treat guilt-free and even share it with folks around you. So give it a go, and you'll be patting yourself on the back later!

Frequently asked questions

The center of the bars will be firm to the touch once they're cooked through. Also, insert a toothpick in the center; if it comes out clean, they are good to go.

You can substitute almond flour with coconut flour, but they have a different texture. Coconut flour absorbs more liquid than almond flour, so here's a general rule of thumb if you use it. Use ¼ to ⅓ cups of coconut flour for every cup of almond flour. And add more liquid to compensate for absorbency. We recommend not substituting with coconut flour for beginners as it might be tricky for you.

This recipe cannot use regular sugar as it is not keto-friendly. Monk Fruit Sweetener Blend is a 0-calorie and 0-net-carb sweetener that makes this recipe keto-friendly. If you want a substitute, you can try other keto sweeteners, such as Stevia or Erythritol.

Traditional marshmallows are typically high in sugar and carbohydrates, which are not ideal for a ketogenic diet. However, the homemade marshmallow created in this recipe is sugar-free and low-carb, made from natural sweetener.

For melting in s'mores, keto-friendly chocolate options include brands like Lily's, ChocZero, and Hu Kitchen. These brands offer sugar-free and low-carb chocolate options perfect for melting in s'mores. Check the nutritional information and ingredients list to ensure that the chocolate fits your keto diet's daily carb and calorie limits.

Mix the raw crust, chocolate filling, and marshmallow topping in a single layer. Place it at the bottom of the fryer basket of an air fryer preheated at 400°F (200°C) and cook for 3-4 minutes until the marshmallows are golden brown and gooey.

Carefully remove the s'mores from the air fryer basket using tongs or a spatula. Let them cool for a few minutes before enjoying your delicious air fryer s'mores!

      Hi Mahima, we haven't tested this recipe with another flour so unfortunately, we can't recommend a replacement.

    These look delish for a snowy day! I wonder if I can sub Bocha Sweet for the sweetener in the marshmallows and then toast them with my creme brulee torch? Looks like a great day for an experiment!

      We've never used Bocha Sweet but as written, these marshmallows will not toast - they'll just melt.
