Corn Flake Cookies are crisp on the edges and soft in the middle, and loaded with corn flakes, oats, and peanuts. They’re perfect with a glass of milk!
This recipe for Corn Flake Cookies is from my late grandmother. She called them “peanut cookies”, but they have more corn flakes than peanuts so I changed the name. 🙂
Grandma noted in her recipe book that the recipe is from her aunt, so these cookies date back several generations! It’s easy to see why the recipe made it into her recipe book—the cookies are soft on the inside, crisp on the edges, and have lots of delicious mix-ins: corn flakes, oats, and peanuts.
Here’s how to make them:
- You’ll need both granulated sugar and brown sugar for this recipe.
- Old fashioned oats (a.k.a. rolled oats) add a great texture to the cookies.
- The peanuts can be honey roasted, salted, unsalted—use whatever you like!
- The corn flakes soften slightly in the cookies, but still leave a “crunch”.
How to make corn flake cookies
In the bowl of a stand mixer, cream together the granulated sugar, brown sugar, and butter. You can also use a handheld mixer.
Add the eggs and beat until combined.
With the mixer on low, add the flour, baking soda, and salt. Mix until just combined.
With the mixer still on low, add the oats, corn flakes, and peanuts. Mix just until the mix-ins are incorporated.
Refrigerate the dough for one hour, or up to 48 hours.
Preheat oven to 375°F. Scoop the dough into 2 tablespoon sized balls (I used a cookie scoop for it—it makes it so much easier).
Bake the cookies for 10–12 minutes, or until golden brown on the edges.
What kind of peanuts should I use?
You can use any type of peanuts that you like (shell off, of course). I used honey roasted peanuts. Unsalted roasted peanuts would be delicious, as would salted roasted peanuts. The cookies will not be too salty if you use salted peanuts.
Can I use quick oats instead of old fashioned oats?
Yes! The cookies will have a slightly different texture, but you can use either quick oats or old fashioned oats in this recipe. I used old fashioned oats, so that’s what the recipe calls for.
Can I add other mix-ins?
Definitely. A cup of chocolate chips or butterscotch chips, added along with the corn flakes, would be really delicious.
