  • Beautiful marbled look and irresistible flavor
  • Melt-in-your-mouth texture with crunchy edges
  • Make-ahead and freezer-friendly

Ingredients (makes 16 bars)

  • 8 oz sugar-free dark chocolate chips (Lily’s, ChocZero, or similar)
  • 8 oz sugar-free white chocolate chips (or sugar-free milk chocolate)
  • ½ cup natural peanut butter (no sugar added)
  • 3 tbsp coconut oil (divided)
  • 3–4 tbsp powdered erythritol or allulose (adjust to taste)
  • 1 tsp vanilla extract
  • Pinch of sea salt (optional but recommended)
  • Optional: ¼ cup chopped peanuts for extra crunch on top

Instructions

  1. Line an 8×8-inch or 9×9-inch pan with parchment paper, leaving overhang on the sides for easy removal.
  2. In a microwave-safe bowl, melt the sugar-free dark chocolate chips with 1½ tbsp coconut oil in 20-second intervals, stirring until completely smooth. Stir in 1–2 tbsp sweetener and a pinch of salt.
  3. Pour the dark chocolate mixture into the prepared pan and spread evenly. Place in the freezer for 5–7 minutes to firm up slightly.
  4. In another bowl, melt the sugar-free white chocolate chips with the remaining 1½ tbsp coconut oil. Stir in the peanut butter, remaining sweetener, and vanilla extract until smooth and glossy.
  5. Dollop the peanut butter mixture over the slightly chilled chocolate layer.
  6. Using a knife or skewer, gently swirl the two layers together to create the tiger-stripe pattern.
  7. Sprinkle with chopped peanuts if desired.
  8. Refrigerate for at least 1–2 hours (or freeze for 30 minutes) until completely firm.
  9. Lift out using the parchment and cut into 16 squares.
