If you have frozen soft pretzel bites, bake them according to the package directions. While they are baking, put together the board.
Grab a large wooden board or even a rimmed baking sheet. Add different sized bowls randomly. Fill bowls with popcorn and nuts. Add another bowl for the homemade snowcaps and one for M&Ms. Fill in spaces with twizzlers or other candies and warm pretzel bites.
