It is almost July, so I definitely don’t want to turn on my oven right now. But, I wanted cookies! So, I searched for no-bake cookies in my newest vintage cookbook, and found Corn Flake Cookies! They are made with chocolate and peanut butter, which is a favorite flavor combination of mine.

Sidenote: this cookbook has been on my wanted list for many years. My grandpa gave it as a wedding gift until 1990 when he could no longer find it. What cookbook is it? It’s “The American-International Encyclopedia Cookbook” by Anne London. The one I found at the local vendor’s market is in almost mint condition, too! If you can find one, I highly recommend it.

What Ingredients Will I Need?

  • Butter
  • Chunky Peanut Butter
  • Mini Marshmallows

Helpful Tips for Making Corn Flake Cookies

  • If the marshmallows don’t seem to be melting on the lowest heat, gradually (and slowly) increase the heat.
  • It is very important to stir constantly so it doesn’t burn!
  • For best results, use butter (instead of cooking spray) to grease the dish the cookies are going in.


  • Use Frosted Flakes instead of Corn Flakes for an even sweeter cookie!
  • Smooth peanut butter can be used instead of chunky peanut butter, if you prefer.
  • Use regular marshmallows in place of mini marshmallows. I would recommend cutting them in fourths for them to melt more quickly.
