Prepare popcorn according to package instructions. Pour into a large bowl and set aside.
3.9 oz. microwave popcorn
Heat oil and white chocolate in a small microwave-safe bowl for 30 seconds at a time. Stir in between until fully melted and creamy. It should take between 1-1½ minutes.
2 tsp canola oil, 1½ cups white chocolate chips
Pour the white chocolate over the popcorn and use a large spoon or spatula to stir all the popcorn until fully coated. It doesn't have to be perfect, you just want it as coated as possible.
Spray a large baking sheet with nonstick spray. Pour the popcorn over the baking sheet while still wet. Sprinkle with the crushed Oreos and extra white chocolate chips.
10 Oreo cookies
Place in the refrigerator for about 20 minutes, or until the chocolate has hardened.
Use a spatula to remove the popcorn from the baking sheet and pour into an airtight container until ready to snack.
