Preheat the oven to 325°F (165°C) and line a large sheet pan with parchment paper.
In a large bowl, mix together the oats, crispy rice cereal, seeds, almonds, flaxseeds, cinnamon and salt.
In a small saucepan, stir together the maple syrup, brown sugar and coconut oil. Bring to a boil, then lower the heat to low and hold at a simmer for about 30 seconds. Turn off the heat and quickly whisk in the almond butter and vanilla until smooth.
Add the wet ingredients to the dry and stir to combine. Spread the mixture on the prepared sheet pan and press down firmly, using a spatula or another sheet of parchment paper. Sprinkle the chocolate chips on top.
Bake for 27 to 30 minutes, or until golden brown. The granola will still be a little soft when it first comes out of the oven. Allow it to cool for 5 minutes, then use a spatula to gently break the sheet into a few large clumps. Allow the granola to finish cooling completely on the sheet pan before transferring to an airtight container.
