Preheat the oven to 325°F and line a baking sheet with a silicone mat or parchment paper.
Combine the oats and salt in a bowl and mix to combine.
Combine the sunflower seed butter, butter, and honey in a microwave safe container and melt. 30 seconds to 1 minute. Stir to combine.
Add the melted honey sunflower butter mixture into the oats with the egg and mix well until the oats are coated completely.
Pour the mixture onto the baking sheet. Spread and pat down until ½" thick across.
Bake for 12-14 minutes, then remove from the oven and let them sit on the counter for 5 minutes. Turn the oven up to 350°F.
After 5 minutes, gently cut them into bars. I usually yield about 15 snack sized bars. Separate gently so there's some room between them.
Return to the oven for 5 more minutes. Remove and let cool completely on the pan.
Store in an airtight container once completely cool for 7-10 days.
