Sugar-Free Keto Peanut Butter Cups Recipe

This is a sugar-free recipe as you can use natural sweeteners such as stevia, monk fruit, or erythritol to sweeten the dish. Personally, I prefer erythritol. I hate the aftertaste of stevia. I’d rather drink my coffee without any sweetener than use stevia!

You can use candy liners or parchment muffin liners to make these designer peanut butter cups. Alternatively, you can go for crude-looking balls too – they taste the same and are simply delicious.

Toss in some crushed peanuts and you have a really crunchy bite too.

Let’s get down to the recipe now.

To make chocolate layers:


  • Dark chocolate – 275 grams
  • Vanilla essence – 1/2 tsp
  • Coconut oil or melted butter – 75 ml


  1. Mix all ingredients together in a double boiler till melted and smooth. You can also use the microwave to make this, but be careful not to overheat the chocolate.
  2. Use half the mixture to create the first layer of chocolate and keep aside the rest to use for the topping. Pour them into the candy liners to create a thin layer of chocolate.
  3. Freeze till set (10 to 12 minutes).

To make the peanut butter center:


  • Creamy peanut butter – 4 tbsp
  • Powdered peanuts – 1 tbsp
  • Coconut oil – 2 tsp
  • Erythritol -5 tsp
  • Salt – a pinch


  1. Heat the peanut butter and oil to gather in a double boiler or in the microwave.
  2. Add in the remaining ingredients and mix well.
  3. Spread a small spoon full of this mixture over the set chocolate. Avoid spreading to the edge if you want a fully chocolate-covered peanut butter cup. You can make the peanut butter center as thick as you like.
  4. Freeze till set (10 to 12 minutes).
  5. Reheat the remaining chocolate till melted and smooth. Pour this over the set peanut butter, allowing the chocolate to cover the sides of the filling as well if desired. You can also consider making three clear layers with the peanut butter sandwiched in between.
  6. Set in the freezer for another 30 minutes till it’s firm.
