Add popcorn into a large mixing bowl. Melt white melting chocolate according to package directions. I heated in a small microwaveable safe bowl for 1 minute, then stir and reheated in 30 second intervals until chocolate was completely melted and creamy.

Pour melted chocolate over popcorn and stir to combine. Immediately pour coated popcorn onto a large baking sheet.

Top popcorn with crumbled red velvet cake and mix popcorn to combine. Don’t mix like a cake just gently toss and turn over popcorn using two mixing spoons or spatulas until popcorn is covered. Let the popcorn sit until all the chocolate is completely hardened. Break up popcorn and serve.
