Popcorn Cake

Ingredients
1 (16 ounce) packages miniature marshmallows
20 caramels
1/4 cup butter, cubed
10 cups popped popcorn
1 1/2 cups salted peanuts
1 cup M&M's plain chocolate candy

Directions
Place the popped popcorn in a large bowl or roasting pan.
In a saucepan, combine the marshmallows, caramels and butter. Heat on low until melted, stirring occasionally.
Pour the caramel mixture over the popcorn and mix well.
Working quickly so that it doesn't harden too fast, stir in peanuts and M&Ms.
Press into a well-greased 10-inch tube pan. Cool until firm.
Remove from pan and cut with a serrated knife.
