Monster Cookies - just like Grandma used to make!

My friend Augusta and I compared our grandmother’s recipes years ago and laughed when they were almost identical.

Side note: We then proceeded to make and eat almost an entire batch on our own, we probably consumed half of it as raw cookie dough – yeah, these cookies are that good.

I thought these cookies were exclusive to my own family and in the past few years, I’ve seen these all over the internet.

If you haven’t tasted them before, you are missing out on one of the best cookies ever.

I only make these cookies a few times a year, because I absolutely cannot eat just one (or two or three). I’ve been known to polish off so many I went to bed nauseous. (How’s that for a selling point? ha)

My brother Karl shares my weakness for these cookies and that’s motivation for me to make these every summer when he visits. And for a major treat? You’re going to want to make these Monster Cookie Ice Cream Sandwiches.

Monster Cookies stay beautifully chewy when frozen. They’re the PERFECT cookie for ice cream sandwich making. (I just skip the candies on top if I know I’ll be making ice cream sandwiches.)

Gluten Free without any special ingredients, these cookies were free of wheat before that was the cool thing to be. The oats and the peanut butter hold them together perfectly. (If you are baking them with allergies in mind, be sure to purchase certified gluten-free oats.)

First, and most importantly, do not overbake these amazing cookies. The cookies should be barely browned around the edges and just past looking wet on top when you remove them from the oven.

Let them cool on the baking sheets for a couple minutes and then transfer to a wire rack to finish cooling.

These cookies are wonderfully chewy and they’ll stay nice for several days when stored at room temperature in an airtight container. They can also be frozen for up to 3 months.

For what it’s worth, Grandma’s Monster Cookies are Oscar approved – not that I let him taste them. But he did give them a dignified nod of approval as he helped me take the photos.

  1. Preheat oven to 350 degrees. Cream together the butter and sugars.
