Cookies! Yum!

I have been feeling nostalgic lately and have been revisiting many of my favorite recipes from my childhood. 

When I was little, my mother would bake cookies that would disappear as soon as she made them.

Snickerdoodles, sugar cookies, and oatmeal raisin cookies. 

(Don’t get me started on the oatmeal raisin/chocolate chip debate…my mother did not like chocolate chip cookies and so never made them. I do like them but a good oatmeal raisin cookie wins this contest with me every time.)

When I was in high school, she would also make what we called “Laverna’s Cookies.”  

They were so good for an after-school snack and, truth be told, they were so much fun to stuff in my pocket and become quick weekday breakfasts! Don’t fool yourself…if people eat chocolate chip cookie cereal for breakfast, you can eat Laverna’s cookies early in the day!

Laverna was my grandmother’s youngest sister and this great recipe was hers.

Do you name recipes based on who gave it to you? My family does!

Grandmother’s Meatloaf, Nana’s Mexican Casserole, My Favorite Lemon Curd…I have a recipe box full of them!

Well, Laverna’s cookies are the ultimate peanut butter cornflake cookie!

This recipe is so easy! You mix everything but the corn flakes over head and, once you get a slight soft boil in the center, you add the corn flakes.

Once you stir in the corn flake cereal, the key is to work quickly as you scoop the cookie mixture onto a cookie sheet.

I like to use an ice cream scoop.

These are sticky when you put them on the baking sheet so it is a good thing these cookies are finger-lickin’ good!

Have you ever baked cookies only to have them dry out and lose their freshness? Here are some tips for storing your favorite cereal cookies.

  1. Make sure you allow the cookies to cool completely at room temperature on a wire rack.
  2. Store in an airtight container and separate the layers of cookies with parchment paper so they don’t stick together.

  1. Hi Missy, I loved reading about where the cookie name came from. Isn’t that a great memory? These cookies look so delicious. I’m definitely adding them to my cookie-baking rotation! Thank you for sharing a great recipe and your family memories! Loved this!

    1. It really is a great memory, Susan! I don’t remember Laverna herself very much because I was so little when she passed. But it is a connection to my grandmother that I love!

  2. 5 stars
    Oh my goodness, Missy! My mom made those, too, (probably your mother’s recipe), and they were so delicious!!! I’d forgotten all about them. I’ll be making them soon! Thanks for sharing!😊

    1. Aren’t cookies from out childhood the best? I used to make them for my kids all the time when they were little and then I kind of forgot about them. Glad to bring them back into our household! It was SO great seeing you! I wish we lived closer!

  3. 5 stars
    Yum! I was thinking as I read this that I might like to add chocolate chips or a chocolate drizzle to these, and then I saw that you suggested this as a variation! You knew there are people like me who always want to add chocolate!

    1. A drizzle of chocolate is always a good thing! Thanks for taking a look and commenting, Julie1

    I’ve made these using instead of Corn Syrup Marshmallows. I have another idea for a really good recipe: 1 bag Mini Marshmallows, 3 Tablespoons Olive Oil (if you use this keep stirring don’t walk away it melts faster than butter) or Butter melt in a pot after melted on low heat, after completely melted dip apples in I suggest Granny Smith or Pink Ladies then roll in Graham Cracker Crumbs then drizzle with melted chocolate.

  6. 5 stars
    I have always made these as bars – we called them Special K bars as the recipe called for using Special K cereal, but I always use corn flakes. And we do top them with a chocolate/butterscotch frosting. So good!
