Make your popcorn on the stovetop (do not use microwave popcorn). Add a small amount of vegetable (or a high heat olive oil) to a 6 quart stockpot.
Add thin layer of popcorn about 1/4 cup of kernels - enough to cover the bottom of the pan. Cover with a lid. Turn to medium heat. When you start to hear popping, watch the pan closely, at this point sometimes I will vent the lid as well. When the popping starts to diminish, turn off burner and remove from stove top. Pour your popcorn into a large bowl.
Preheat oven to 250 degrees. Line a large rimmed baking sheet with parchment paper.
In a small saucepan, add the coconut oil, maple syrup, brown sugar and cinnamon. Turn burner on low heat and melt all ingredients. When the mixture starts to boil, boil and stir constantly for 2 - 3 minutes, until it starts to ‘thicken’ slightly.
Turn burner off - remove pot from stove. And add in both vanilla and baking soda. Mixture will bubble! Stir until well mixed. Pour over popcorn. Mix well.
Pour popcorn onto prepared baking sheet.Bake for 45-55 minutes. Stirring after every 15 minutes.
Cool on wire rack. Store in airtight container away from sunlight.
