Old-Fashioned Peanut Butter No Bake Cookies

Creamy peanut butter and oats come together in these easy no bake cookies.  A quick homemade treat from my mother’s old newspaper recipe collection.

When the weather turned warm, my mother liked making simple desserts that didn’t require heating up the kitchen. These peanut butter no bake cookies came from an old newspaper clipping she saved and often used during the busy summer months.

She spent so much time gardening, canning, and keeping up with things around the house that quick recipes like this became family favorites. They came together fast, used simple pantry ingredients, and always disappeared quickly from the cookie plate.

One thing I always remember about this recipe card is that the original newspaper recipe called for 3 cups of sugar, but my mother thought they were much too sweet. She crossed out the “3” and wrote a “2” beside it instead. Our family always made them with 2 cups of sugar, but if you prefer sweeter old-fashioned no bake cookies, you can still use the full 3 cups from the original recipe.

The combination of creamy peanut butter and oats makes these cookies rich, chewy, and comforting in the best old-fashioned way. 

Ingredients: 

2 c. white sugar or 1 c. granulated sugar and 1 c. brown sugar OR
