Prepare a large tube or bundt pan by spraying evenly with cooking spray.
Pop 2 bags of buttered microwave popcorn as directed on the package and dump into a large bowl.
{I used "Butter Lovers" because I am out of my mind}
Pick out the kernels that didn't pop...broken teeth aren't so cute.
Now mix in 2 cups of M&M's and 1 1/2 cups broken pretzel sticks..not crushed, just broken into smaller pieces...
Melt 1 stick of butter over low in a large saucepan.
When melted add in a 16 oz bag of mini marshmallows (8 cups)
Stir until melted and smooth.
Remove from heat and pour over your popcorn mix.
Stir until all the ingredients are combined and then press into the prepared pan.
Cover with foil and let your cake set for at least an hour to cool.
When you are ready to serve the cake loosen sides of your cake from the pan by running a butter knife around the edges.
Flip your pan over onto your serving platter.
Your cake should come out pretty easily.
{You want it to cool completely so it will cut nicely}
Now there's nothing wrong with that!
