Preheat oven to 250 degrees and line a large rimmed baking sheet with parchment paper.
Prepare your air popped popcorn and place in large bowl.
Combine coconut oil, agave, brown sugar, peanut butter powder and salt in small saucepan on stove.
Bring liquids to a boil and boil 3 – 5 minutes stirring constantly.
Remove from heat, add soda and extract (this will bubble!). Continue to stir to combine into a sticky liquid.
Working quickly, pour the liquid mixture over prepared popcorn and mix well.
Pour on prepared baking sheet.
Bake in oven for 45 minutes, stirring every 15 minutes to evenly coat popcorn and prevent burning.
Remove from oven, sprinkle with chocolate chips and cool on wire rack.
Store in airtight container.
