In a mixing bowl, combine the soaked dates, peanut butter, and oats. Mix until well combined and a sticky dough forms.

Line a loaf pan with parchment paper. Press the date mixture into the bottom of the pan evenly.

In a small bowl, mix together the maple syrup and peanut butter until smooth. Spread this mixture over the base layer in the loaf pan.

Drizzle the melted dark chocolate over the caramel layer and sprinkle with chopped peanuts.

Refrigerate for at least 1 hour to set. Once set, cut into bars and serve.
