Preheat the oven to 350 degrees F.
Line a standard loaf pan with parchment paper and place to the side.
In a blender or food processor, add ¾ cup oats and the pepitas and blend until finely ground and place in a large bowl.
Add the egg whites, maple syrup, sunflower seed butter, melted butter, and vanilla extract to the mixture and blend until combined.
Next, add chia seeds, ground flax seeds, kosher salt and chopped dates and combine until completely mixed together.
Lastly, fold in the remaining ½ cup oats.
Pour into the lined loaf pan and bake for 20-25 minutes.
While the granola bars cool, melt the chocolate chips with 1 tsp butter in the microwave for 15 second increments, stirring between.
Drizzle on top of the cooled bars and finish with sea salt.
Place in the freezer to set for 20 minutes, slice into 10 bars and enjoy.
