Ingredients
  

  • Peanut butter: Use a natural, no-sugar-added creamy peanut butter. Check the label for just peanuts and salt.
  • Coconut oil or butter: Helps the filling set and adds a silky texture. Coconut oil firms up a bit more than butter.
  • Cream cheese (optional): Adds a cheesecake-like tang and extra creaminess. If you’re dairy-free, skip it.
  • Powdered keto sweetener: Erythritol, allulose, or a blend. Powdered dissolves better than granular.
  • Vanilla extract: Rounds out the flavor and softens any aftertaste from sweeteners.
  • Salt: A pinch brightens everything, especially if your peanut butter is unsalted.
  • Sugar-free chocolate chips or bars: Choose a brand with low net carbs and clean ingredients. Darker chocolate works best.
  • Coconut oil (for the chocolate): Helps the chocolate melt smoothly and set with a nice snap.
  • Silicone mini muffin mold or paper liners: For neat, bite-sized portions and easy release.

Method
 

  1. Prep your pan: Line a mini muffin tin with paper liners or use a silicone mold. Clear some space in the freezer.
  2. Make the peanut butter base: In a bowl, mix 3/4 cup natural peanut butter, 2–3 tablespoons melted coconut oil or softened butter, 2–3 ounces softened cream cheese (optional), 2–4 tablespoons powdered sweetener, 1 teaspoon vanilla, and a pinch of salt. Stir until smooth and fluffy. Adjust sweetness to taste.
  3. Portion the filling: Spoon about 1 tablespoon of the mixture into each cup. Tap the tray gently to level the tops.
  4. Chill: Freeze for 15–20 minutes, until firm to the touch. This helps the chocolate layer go on cleanly.
  5. Melt the chocolate: In a microwave-safe bowl, combine 3/4 to 1 cup sugar-free chocolate chips with 1–2 teaspoons coconut oil. Heat in 20–30 second bursts, stirring between each, until smooth. Or melt gently on the stovetop using a double boiler.
  6. Coat with chocolate: Spoon a thin layer of melted chocolate over each chilled peanut butter cup, just enough to cover the surface. Tilt the pan to spread if needed.
  7. Set the tops: Return the tray to the freezer for 10–15 minutes, until the chocolate is firm.
  8. Optional finish: For a thicker shell, add a second chocolate layer after the first sets. You can also sprinkle flaky salt or chopped peanuts on top before the chocolate hardens.
  9. Store: Once fully set, transfer the fat bombs to an airtight container. Keep them chilled so they stay firm.
