Blitz the rice cakes in a food processor until fine then tip into a large bowl. Add the peanut butter and honey before stirring well until the mixture comes together. Press firmly into a lined 20cm square baking tin, creating an even layer. Place in the freezer for 10 minutes while you prepare the date caramel.
Middle Layer
Blend the dates in the food processor until smooth and sticky. Add a splash of water if needed. Spread the date mixture evenly over the base layer and place in the freezer for 30 minutes.
Top Layer
Melt the dark chocolate with extra virgin olive oil in short bursts in the microwave or over a bain-marie. Pour over the date layer and smooth out with a spatula or using your finger tips. (if using your finger tips, have a bowl of water at the side of you and keep your fingers damp as the caramel layer is sticky)
Return to the freezer for around 15 minutes until set.
Slice into bars or squares using a sharp knife. Keep chilled until ready to enjoy.
