Method
 

  1. Prep pan: Grease an 8x8-inch pan, line with parchment paper leaving an overhang on all sides.

  4. Swirl: Pour chocolate layer into pan. Spoon peanut butter mixture on top. Swirl with a butter knife.
  5. Chill: Refrigerate at least 2 hours until completely firm.

Notes

  • If layers won’t combine when swirling, microwave the chocolate layer an extra 20–30 seconds before layering
  • Tap the pan on the counter to level the surface after pouring
  • Store in an airtight container at room temperature up to 1 week, or refrigerate up to 2 weeks
  • Freeze up to 1 month with parchment between layers
