To prepare in advance
- With the rack in the middle position, preheat the oven to 325°F (165°C). Line an 8-inch (20 cm) square pan with a strip of parchment paper, letting it hang over two sides.
- In a blender or small food processor, purée the dates with the water, maple syrup, almond butter and vanilla until smooth. Transfer to a large bowl. Add the remaining ingredients and mix well. Spread the mixture out in the prepared pan and press down firmly with your fingers.
- Bake for 15 minutes or until the oats and rice cereal are lightly golden. Let cool. Unmould. On a work surface, cut into 10 bars. The energy bars will keep for 1 week in an airtight container at room temperature.
