Grandma's Oatmeal Cookies: A Family Recipe

Recently, I went rummaging through my cupboards to take stock of ingredients I had on hand. I wanted to make something sweet, but I was out of butter and baking soda. I had peanut butter, oats, and baking powder. I also had plenty of sugar. Flipping through my secret family recipe book, I landed on our family's oatmeal cookie recipe. I took a few creative liberties and got to work, making a mess and baking.

Grandma's peanut butter oatmeal cookie recipe was born! About an hour later, I had a few pans full of scrumptious cookies. One bite, and I was hooked!

These cookies are delicious! They are soft, crumbly, and filled with peanut buttery goodness.

Ingredients needed

Ingredients needed


  • 1 cup brown sugar
  • 1 cup granulated sugar
  • 1 1/2 cups flour
  • 1 teaspoon salt
  • 1 1/2 teaspoons baking powder
  • 3 cups rolled oats
  • 1 cup shortening
  • 3 cups peanut butter
  • 2 eggs


  1. Preheat oven to 375 degrees Fahrenheit.
  2. In a large mixing bowl, combine sugars, flour, salt, and baking powder. Using a fork, gently sift through to get rid of any lumps.
  3. Add in oats. Mix well.
  4. Stir in shortening. Mix well.
  5. Add in peanut butter. I like to use my hands to ensure that the dough is evening mixed.
  6. Stir in eggs.
  7. Roll the dough into medium-sized balls. Place on a greased cookie sheet.
  8. Optional: Dip a fork into flour. Make a criss-cross pattern across the top of each ball, as you would for a traditional peanut butter cookie.
  9. Bake for 15 minutes.


These cookies are filling. Serve warm with a glass of cold milk before bedtime or as a snack. I like to have a few for breakfast with my coffee. You might try having a cookie or two with a side of vanilla ice cream.

Yummy cookies and a hot cup of coffee—perfection!
