10.5 oz. package of marshmallows
16 c. popped popcorn (a little less than 3/4 c. unpopped)
1/4 c. butter
1 large bag Peanut M&M's (I used the Easter ones!)
Pop your popcorn first! I use microwave popcorn so a few bags.:)
In a large pot, melt the butter over medium heat, then add the marshmallows. I stir pretty constantly, to make sure the marshmallows don't burn on the bottom. Once it's completely melted, pour on top of your popped corn, and stir until every piece is covered. Add your M&M's, and gently stir them into the popcorn, making sure they are throughout the whole bowl.
Spoon the popcorn mixture into a lightly buttered bundt pan, and press firmly. (Don't use cooking spray--it will make it taste funny.) You don't need to let it sit for very long--only about 5 to 10 minutes, then you can turn it upside down onto a cake plate. You will probably need to take a table knife and gently go around the edges, then use your fingers to loosen it a little. Once it's loosened, it will come out pretty easily.
