A quick and easy keto-friendly peanut butter cups recipe featuring a creamy 3-ingredient filling and a rich chocolate shell, perfect for satisfying sweet cravings without the sugar crash.

Ingredients

Scale
  • 1 cup unsweetened baking chocolate (preferably 70% cocoa or higher)
  • 2 tbsp coconut oil
  • 12 tbsp erythritol or preferred keto sweetener
  • 1/2 cup natural peanut butter, smooth (no added sugar or oils)
  • 1/4 cup cream cheese, softened (full fat)
  • 1 tsp vanilla extract
  • Optional: a pinch of salt if peanut butter is unsalted

Instructions

  1. Prepare your molds: Line a mini muffin tin with paper liners or grease silicone molds lightly with coconut oil.
  2. Melt the chocolate shell: In a microwave-safe bowl, combine 1 cup unsweetened baking chocolate, 2 tbsp coconut oil, and 1-2 tbsp erythritol. Microwave in 30-second bursts, stirring in between, until smooth and glossy (about 2-3 minutes total).
  3. Form the chocolate base: Spoon about 1 tbsp of the melted chocolate into each mold, spreading it evenly across the bottom and slightly up the sides. Refrigerate for 10 minutes to firm up.
  4. Make the creamy filling: Mix 1/2 cup smooth natural peanut butter, 1/4 cup softened cream cheese, and 1 tsp vanilla extract in a bowl. Beat until silky and well combined. Add a pinch of salt if needed.
  5. Layer the filling: Once the chocolate bases are firm, add about 1 tbsp of the creamy peanut butter filling on top of each. Flatten gently with the back of a spoon.
  6. Seal with chocolate: Cover the filling with another tablespoon of melted chocolate, making sure to seal the edges.
  7. Chill to set: Refrigerate the peanut butter cups for at least 30 minutes until fully firm and set.
  8. Serve and enjoy: Carefully peel off liners or pop out from molds. Store in the refrigerator for best texture and freshness.

Notes

Use room temperature cream cheese for smooth filling. Let chocolate chill well between layers to prevent cracking. Temper chocolate if possible for shiny finish but gentle melting works fine. Adjust sweetener to taste. Work quickly when layering chocolate to avoid hardening.
