Soak the dates in boiling water for about 5 minutes or until soft.
Drain the water from the dates and add them into a blender along with some fresh cold water. Blend until smooth and creamy.
Pout the date caramel into a large bowl and add oat flour, salt, and peanut butter.
Combine and create a thick but sticky dough.
Transfer the dough into a square pan or loaf pan and spread it out with a spatula. The dough should be 0.7 inches thick (2cm).
Melt the dark chocolate and pour it over the dough. Let the bars chill in the fridge for at least 2 hours before serving. Enjoy!
