The Perfect Monster Cookie Recipe

You absolutely have try this monster cookie recipe. It is perfect!

You all know I don’t like to cook. If I were rich, I would totally have a personal chef who would cook me nutritious, perfectly balanced meals every day. Huge chicken Ceasar salads, juicy hamburgers made with lean beef and tons of roasted veggies. Oh, and every so often, bake me monster cookies.

These monster cookies will make your tastebuds sing for joy and your kids sing your praises.

But, alas, this blog has yet to make me rich and my kids still want to eat every day, still outgrow their shoes, and expect us to pay for dental visits. So instead I have been forced to experiment time and time again until I perfect my favorite recipes. And today, I am sharing with you The Perfect Monster Cookie Recipe.

The perfect monster cookie recipe for hungry kids and stressed moms.

First off, a few words about monster cookies. They should be BIG and chewy, so you want to make sure you don’t overcook them.  I have found (through rigorous testing) the exact balance between M&Ms, chocolate, and Reese’s Pieces. Don’t mess with this!

Also, are fans of Adams Natural Peanut Butter, but do not use the natural peanut butter with these cookies. To get the right texture, use regular peanut butter. For these, I used peanut butter purchased from Brandless (more on that later since I am working on a review).

Monster cookies don’t contain any wheat flour. I have found that to get The Perfect Chunky Chewy Texture you need to make some oat flour. All you need to do it take a cup and a half of old-fashioned oats and whir them in the blender for a few seconds. This will give you a beautiful oat flour to use in your monster cookies.

The only monster cookie recipe you will ever need.

And now, with no further ado, The Perfect Monster Cookie Recipe.

  1. I’m going to try these. They look great. But I had no idea you hated cooking. You make so many great things. A friend suggested an Instapot to me–they do look great. You would need the largest size, possibly two, but you would sooooo enjoy.

    • Seriously? I thought I started every cooking/recipe post wit the caveat that I hate cooking. The only thing that saves us is a tight budget and my love of EATING good food. I have an Instant Pot and have posted several recipes here. One is plenty for us. I cook the main dish in and then make sides.

  2. Thank you for this recipe Renee. I haven’t baked cookies in years but these are tempting enough to try because I always loved chewy cookies. Also I thought of you earlier today when I read a blog from a dad in eastern Canada on supporting emotional regulation for children with ASD and FASD diagnoses. You probably already know this information but I usually learn something from everything I read so I thought I’d share this one with you.

Please share your thoughts!
