Preheat oven to 350º.
Place the sunflower seeds and pumpkin seeds on a parchment paper-lined pan and roast for 8 minutes.
Reduce oven temperature to 325º
In a medium pot on med-low heat, add the syrup, brown sugar, cinnamon, coconut sugar, and cranberry juice. Heat and stir until sugar is completely dissolved then remove from heat.
In a large bowl, mix together the oats, pumpkin seeds, sunflower seeds, almonds, and sea salt. Mix with a spoon (mixing with your hands does a much better job!) until combined.
Place mixture back onto the parchment-lined baking sheet and spread out to fill the pan.
Bake for 20 minutes then stir in cranberries.
Return to oven and bake for 30-35 more minutes. Remove when still slightly "uncrunched" because it will continue to crisp up as it cools.
