This low carb sugar-free Keto peanut butter cups recipe is so easy to make and perfect for people watching their carbs, who love Reese’s peanut butter cups.

Just because you are on a low carb diet or Keto diet it doesn’t mean you can’t satisfy your sweet tooth with some fat bombs that are yummy. That is where these amazing homemade keto peanut butter cups come in. They are super simple to make using just a handful of ingredients. If I can do it, you can do it. Let’s get started!

Gather the ingredients

Several ingredients like chocolate chips, coconut oil, salt, almond flour, and peanut butter on a counter.

To make Keto peanut butter cups or peanut butter cups that are Keto friendly, you need a handful of simple ingredients:

  • Sugar-free chocolate chips – Typically these will be dark chocolate.
  • Coconut oil – The oil will help smooth out the melted chocolate chips. You can also use cocoa butter.
  • Natural peanut butter – Use store-bought creamy peanut butter or easy homemade peanut butter. Just make sure they are sugar free. You may use other natural nut butter if you like, like almond butter, cashew butter, etc.
  • Almond flour
  • Salt – This will balance out the sweetness.
  • Xylitol sweetener – Will add a hint of sweetness to the chocolate and peanut butter.
  • Vanilla extract – this is optional, but will add a bit of flavor.


  • Bowls
  • Spoon
  • Microwave or double boiler
  • Paper cups
  • Muffin pan

How to make Keto peanut butter cups

Hand adding peanut butter to a bowl.

Begin by adding the peanut butter to a medium bowl. The amount doesn’t have to be exact for this recipe. Start with 1/2 to 2/3rd cup of peanut butter. You can always add more later.

Then start adding in the almond flour, you may not wind up using it all. Mix in the xylitol sweetener, a pinch of salt, then a little more almond flour until the mixture is no longer really sticky.

In my classic homemade peanut butter cups, I add powdered sugar instead of almond flour to make the peanut butter less sticky. You could just follow that exact recipe but use sugar-free chocolate chips and almond flour instead of powdered sugar.

Now the peanut butter mixture is ready to go.

Melt the chocolate

Glass bowl full of chocolate chips and coconut oil.

Time to melt the sugar-free chocolate chips. Add them to a bowl along with the coconut oil and a pinch of salt. And then place the bowl on top of a small pot with about a cup of water in it.

Turn the heat on medium and the steam from the water will gently heat the bowl and melt the chocolate. Stir frequently while the chocolate is melting until melted.

TIP: Room temperature chocolate chips will melt faster.

You may also melt the chocolate in a microwave-safe bowl in the microwave using bursts of 25 to 30 seconds and stirring until melted.

Finish off the easy Keto peanut butter cups

Hand spooning in peanut butter mixture into muffin cups with chocolate.

Now take a muffin pan, either the normal size for large peanut butter cups or mini size for small ones, and add the cupcake liners. Spoon in about a teaspoon of melted chocolate onto the bottom of each cup.

Then come back and add a spoonful of peanut butter filling to the top.

Next, completely cover the top of each peanut butter layer with melted chocolate. Give the pan a few taps on the counter to settle everything and then place it in the fridge for 30 minutes or so for the chocolate to set.
