Ingredients
Here are the ingredients you'll need:
Peanut butter - Make sure your peanut butter isn't runny. On the firm side of gooey is best.
Butter and coconut oil - These are interchangeable. If you don't like or can't have one or the other, simply swap them out.
Chocolate - Use either sugar-free chocolate chips or a dark chocolate with at least 85% cocoa solids, preferably 90%.
Sweetener - I used Lakanto Classic, which is an erythritol monk fruit sugar substitute. Allulose, Bocha Sweet or xylitol also work. The sweetener for the peanut butter filling should be powdered.
Salt - I added sea salt because my peanut butter did not contain added salt. If yours contains salt, you may not need it.
Instructions
This section contains step-by-step instructions and photos that show how to make this recipe. See the recipe card for full information on ingredients and quantities
First, combine the base ingredients in a large mixing bowl...
...and press them into a baking pan lined with parchment paper.
Next, stir together the peanut butter mixture...
...and spread it over the crust. Freeze until set.
Then melt the chocolate and coconut oil (or butter)...
...and pour over the peanut butter layer. Freeze again or cool in the fridge until set!
Top tip
Let the low carb peanut butter bars stand at room temperature for 20 minutes before slicing. Then, warm a large knife under hot water and slice with a rocking motion rather than moving the knife forward and backwards.
This way, the chocolate layer does not crack when you slice the bars.
What I learned
I used the granulated sweetener for the base layer, but powdered some for the peanut butter layer. You don't HAVE to do this, but I did not want the middle layer to taste gritty. I simply blended 1 cup of sweetener in the food processor to powder it and stored the rest.
Don't use runny peanut butter. Dig down into your pot and use the firmer part! To further firm things up you can also add 1 tablespoon coconut flour.
In my opinion, the salt in the peanut butter layer is ESSENTIAL! It really gives the bar that extra oomph.
FAQ
How can I make these dairy-free?
Use coconut oil instead of the butter.
Can I use almond butter instead?
Of course. Any nut butter works. Almond butter tends to be more runny than peanut butter, so you may need to add a little coconut flour to firm it up.
Is there a nut-free version?
You can use a blend of sesame seed flour and sunflower seed flour in place of the almond flour. Or, leave out the crust completely.
Storage
After slicing, I recommend that you store these keto peanut butter bars in the fridge or in the freezer. They last at least 1 week in the refrigerator (after that mine were gone!).
Freeze them sliced and wrapped in parchment paper so they don't stick together. Freeze for up to 6 months.

Ingredients
Base
- 1.5 cup / 150g almond flour
- 3 tbsp / 30g Lakanto Classic
- 5 tbsp / 70g butter melted
PB Layer
- ¾ cup / 190g peanut butter (use firm peanut butter, no runny oils)
- 3 tbsp / 45g butter melted, (or coconut oil)
- 2 tbsp / 20g Lakanto Classic powdered
- ½ teaspoon salt to taste
Chocolate Layer
- ⅔ cup / 4.4 oz / 125g sugar free chocolate or dark chocolate, at least 85% cocoa solids
- 2 tbsp / 28g coconut oil (or butter)
Instructions
Base: Place all the ingredients in a mixing bowl and stir together. Line a small baking tray (24cm x 16cm) with greaseproof paper. Press the mix to form a base.
Peanut Butter Layer: In a clean bowl, add the peanut butter, butter, powdered Lakanto and sea salt. Whisk with a hand ballon whisk to combine. If your peanut butter is too thick, warm it slightly first. Spread over the base and freeze until set, about 10 - 15 minutes.
Melt the chocolate and coconut oil in a heatproof bowl over a pan of boiling water (bain marie). Allow to cool slightly, then spread on top of the peanut butter layer. Place in the fridge for at least 2 hrs or until fully set (or freezer for about 30 minutes).
Let the bars come to room temperature before cutting. Run a shape knife under hot water and slice. This will help prevent the chocolate layer cracking.
Notes
Makes 16 bars. 3.1g net carbs per bar.
The recipe uses Lakanto Classic for the base and powdered Lakanto Classic for the peanut butter layer. I simply blended 1 cup in the food processor until it was powdered and stored the rest.
Store in the fridge for up to 1 week or in the freezer for up to 3 months.
