Preheat your oven to 250F and lay a Siplat baking mat down on 2 large baking sheets (or you can lightly oil them). Make sure your popcorn is in a large bowl, waiting to be covered in this yummy caramel sauce.
In a medium pot, melt the vegan butter over medium heat, then add in the salt, brown sugar, vanilla and maple syrup. Bring to a boil.
Allow to boil for about 5 minutes, then remove from heat and add in the baking soda. Mix well, and pour over your popcorn right away.
Mix in the caramel, making sure to cover all of the popcorn. Then, pour the popcorn onto the 2 baking trays and bake for 30 minutes.
Remove from oven and stir, then allow to cool for about 15 minutes.
