Peanut Butter Chocolate Oat Cookies

Have you ever looked up the definition for the word, “colossal”?

If you haven’t, it’s hysterical. Colossal simply means “extremely large”. Not ginormous. Not freaking huge. Not even a whoaaaa bessie. Just extremely large. What could be bigger than extremely large? A thirty-story building? A space shuttle? The world’s largest ball of twine? I think even the giant from Jack and the Beanstalk is shrugging his shoulders with confusion.

Anyway, this cookie recipe comes from the Grier family vault of recipes written by Mr.B’s late grandmother, Granny. The woman knew her cookies. Her gingersnaps were absolute sugar perfection. As I was looking through the recipe vault trying to gather ideas of what I wanted to make, I asked Mr. B, do you remember eating these colossal cookies as a kid? Mr. B’s eyes lit up like a Christmas tree. “Oh, YES! We would actually help Granny make these cookies all the time.”

My heart melted a little. Granny was always good about taking the approach that, if you can read, you can cook. She was wired to love, teach, and get things done. I miss her, especially her humor. Even though I didn’t get a chance to ask why these cookies were named “colossal”, I kind of feel like she looked at the definition and laughed a little too.

Peanut Butter Chocolate Oat Cookies

Yes, these cookies are extremely large, but they don’t skip on flavor. Did I mention that there’s an obscene amount of oats, chocolate chips, oh and a jar of peanut butter in the batter? I know, have mercy, right? As I was scooping these bad boys onto a  baking sheet, I started to giggle. Not only are the cookies crazy big, but there’s an eff ton of batter!

If you need a good laugh over the holidays, make these cookies. They bring out colossal smiles in all of us.
