For those who love popcorn, marshmallows and M&M's, will definitely enjoy this cake. My favorite M&M's to use in this cake, are the peanut M&M's. (Also, when making this recipe, I did use a large Teflon coated pan/kettle.)
1Make microwavable popcorn according to instructions on the bag. Discard any un-popped popcorn seeds from the bag.
2Butter the inside of one 8x8-inch pan with a bit of butter. Then line inside of pan with plastic wrap.
3In a large kettle or Dutch oven, add the 1/4 cup of butter. (I used a large Teflon coated kettle/pan, when making this recipe.) Melt the butter over low heat, then add the marshmallows; stirring until marshmallows have melted completely.
4Remove kettle from stove, and quickly stir the melted marshmallows and popcorn together.
5Add the M&M's, and quickly stir them in as well.
6Pour the popcorn mixture into the prepared pan.
7With buttered hands, press popcorn mixture down into the pan.
8Cover pan with plastic wrap, and set pan aside to cool for a few hours before cutting into squares. (I let mine set for at least 4 hours.)
9*Note: I have also made this with 4 cups of miniature marshmallows. With the extra marshmallows added, this will make 8 servings.
