Begin by melting chocolate in the microwave in 30-second intervals with a bit of oil. Once melted, stir in peanut butter.
Fill silicon liners with the chocolate mixture, then add a slice of banana.
Next, add peanut butter and jelly. Swirl them together using a toothpick.
Sprinkle chopped roasted peanuts on top, then drizzle with more melted chocolate.
Place in the freezer to fully harden, approximately 20-30 minutes.
Once set, remove from liners and enjoy!
