I stumbled upon these sugar-free keto peanut butter cups during a late-night snack attack, and let me tell you, it’s been a delicious spiral ever since. Imagine that perfect balance of creamy peanut butter and rich chocolate flavor—without the guilt. They’re like a tiny festival of flavor in your mouth, and trust me, you won’t believe they’re keto-friendly.
Steps
- Prepare the bottom chocolate layer by melting half of the chocolate chips and coconut oil using a double boiler or microwave. Stir frequently until smooth, and optionally add vanilla extract for flavor. Pour this chocolate mixture evenly into the bottom of parchment-lined muffin cups and freeze until firm.
- For the peanut butter layer, melt the peanut butter with more coconut oil in either a double boiler or microwave. Mix in powdered sweetener, peanut flour, and optional vanilla and sea salt until smooth. Place a spoonful of this mixture onto the chocolate layer in each cup, allowing it to spread slightly without reaching the edges, and freeze until firm.
- Create the top chocolate layer by melting the remaining chocolate chips and coconut oil, as previously done. Stir in the remaining vanilla extract if desired. Pour this over the peanut butter layer in each cup, ensuring it covers the sides and top, then freeze until completely firm.
- Store the finished peanut butter cups in an airtight container in the refrigerator to maintain their texture. For longer storage, freeze them for up to six months, enjoying them directly from the freezer or thawing as desired.

FAQ
- Can I use a different type of nut butter for the filling?
- Yes, you can substitute other nut butters such as almond butter or sunflower seed butter. However, they tend to be runnier than peanut butter, which might affect the texture of the filling.
- How should I store these keto peanut butter cups?
- Store them in an airtight container in the fridge to keep them firm. They can last for several weeks when stored this way.
- Can these peanut butter cups be frozen?
- Absolutely, they freeze well for up to six months. You can enjoy them straight from the freezer or let them thaw in the refrigerator or at room temperature.
- What can I do if my filling comes out grainy?
- Ensure you’re using a powdered sweetener that dissolves easily, like powdered Besti. Many other sweeteners, especially those with erythritol, can leave a grainy texture.
- Are there variations to make these cups more festive for holidays?
- Yes, you can make them in different shapes using themed molds for occasions like Easter or Halloween, or use decorative wrappers to fit the holiday theme.
Tips
- Choose Thick Peanut Butter: Opt for a thick and creamy natural peanut butter without added sugar. Runny peanut butters can affect the texture of your cups. Check labels to ensure you’re choosing the right kind.
- Use a Double Boiler for Melting: When melting chocolate and coconut oil, a double boiler provides better heat control compared to a microwave, helping prevent the chocolate from burning.
- Add Coconut Oil for Structure: Incorporate coconut oil into both the chocolate and peanut butter layers to help set the texture. Make sure to use the type that is solid at room temperature for best results.
- Store Properly for Freshness: Keep these treats in an airtight container in the fridge to maintain their firmness and freshness. They can also be frozen for up to six months, offering a delightful melt-in-your-mouth experience straight from the freezer.
