- 1/4 cup margarine
- 1 tablespoon peanut butter
- 5 cups miniature marshmallows, divided
- 6 cups honey nut-flavored cereal squares (such as Honey Nut Chex®)
- 2 cups candy corn
- 1/2 cup peanuts
- Grease a 9×13-inch baking pan.
- Cook and stir margarine and peanut butter together in a saucepan over medium heat until smooth, 2 to 3 minutes. Add 4 cups marshmallows to margarine mixture; cook and stir until marshmallows are melted, 2 to 3 minutes. Remove saucepan from heat.

Pour mixture into the prepared baking pan, pressing down in an even layer with buttered hands or a buttered wooden spoon. Cool completely before cutting into squares.
