Add the Earth Balance Buttery Spread and Nutiva Butter Flavor Coconut Oil to a small glass bowl. Heat in the microwave on high power for about a minute, until completely melted. Stir to mix together.

Add the popcorn kernels to a brown paper lunch bag. Fold the top of the bag over twice, then lay the bag flat in the microwave with the seam facing down.

Pop the popcorn. The following times work in my microwave, but you may have to adjust them for your microwave. Cook on high for 1 minute 30 seconds, then remove the bag. Hold the bag from the top, and shake to get all the unpopped kernels to go to the bottom. Carefully open the bag, and scoop all the popped popcorn into a large bowl. Be careful not to touch the unpopped kernels as they are burning hot! Fold the top of the bag over again, and put it back in the microwave. Cook on high for another 50 seconds, then add the rest of the popped popcorn to the bowl. Most of the kernels should have popped and you should have about 8 cups of popped popcorn.

Drizzle the melted butter mixture over the popcorn, stirring after each spoonful. Add salt to taste, then mix well.
