Computer Chip Snack (Marshmallow Peanut Butter Popcorn)

I'm not sure how this recipe got its name, but that is how it was passed on to me from my aunt. I have looked through the site and been unable to find a recipe quite like this one which combines popcorn with melted peanut butter and marshmallows rather than with a boiled syrup. This is a very addicting snack. Our family rarely adds the peanuts or the salt.

• Ready In: 20 mins
• Yields: 12 cups

Ingredients

• 8  cups  popped popcorn
• 3  cups  plain  Cheerios toasted oat cereal
• 1⁄4 cup salted peanuts (optional)
• 1⁄4 cup margarine
• 1⁄2 cup peanut butter
• 1⁄2 teaspoon salt (optional)
• 25  large marshmallows

Directions

1. Preheat oven to 250°F.
2. Combine the popped popcorn, the cheerios and the peanuts in a large bowl and set aside. I like to take the time to pick out and discard any unpopped kernels.
3. Melt the margarine, peanut butter, marshmallows and salt in a bowl in the microwave on High setting until smooth. Microwaves differ in power so check the mixture often, stirring each time until the ingredients are completely melted and well blended.
4. Pour the melted ingredients over the popcorn mixture and stir well, coating the entire mixture.
5. Spread evenly on 2 cookie sheets and bake in the pre-heated oven for 10 minutes.
6. Remove from oven, cool and break apart into chunks.
7. Store in an airtight container.
