A longtime family favorite recipe.

Why I’m JUST now sharing this recipe after 4 years of this blog’s existence beats me! But lucky for you, because today is the day. These Monster Cookies have been a favorite in my family since I started making them back in high school (a long time ago). Over the years, I’ve tweaked the recipe that I first started with (likely found on several times which evolved into what I’m sharing today. My Monster Cookies are a recipe I make all year round – especially during the holidays. They come together quickly and can be made all in one bowl. All you have to do is add the ingredients to a bowl, give them a stir, transfer to a cookie sheet and bake them. In no time at all, you’ll be sinking your teeth into warm, peanut butter-y, oatmeal cookie goodness!


These Monster Cookies can be made peanut- or nut-free with one simple substitution.

Now if you’re looking for a cookie option that’s peanut-free, you can simply substitute almond butter or cashew butter for the peanut butter. Both of these nut butters have a neutral flavor and will work well in this recipe. If you want to make the cookies completely nut-free, you can substitute sunflower seed butter for the peanut butter. This will change the flavor of the cookies a bit, but they’ll still be totally delicious!

A quick note about candy-coated chocolate pieces.

Though this post is not sponsored, I do want to give a quick and well-deserved shout-out to Little Secrets! The makers of the candy-coated chocolate pieces you see used in this recipe. If you’re looking for a dye-free, better-for-you alternative that’s similar to M&M’s, you’ll want to check them out! The chocolate pieces are made with non-GMO, Fair Trade Certified chocolate and no artificial colors (food dyes) or corn syrups. In these Monster Cookies, I like to use a combination of the Little Secrets Dark Chocolate Pieces and Little Secrets Peanut Butter Pieces. So good! You can browse and shop all of the Little Secrets products, here OR see where they’re available in a store near you here.

Add a stash to your freezer.

A cookie stash in your freezer is always a good idea! For many reasons:

  • Something delicious to offer to a surprise (or planned) guest.
  • The perfect treat to bring to a new mom, a neighbor or a special someone “just because.”
  • Something to have on hand for those last-minute situations – a treat to bring to a holiday gathering, birthday party, work potluck, etc.
  • You just never know when you’ll have a mad craving for a cookie!

If you plan to add a stash of these scrumptious Monster Cookies to your freezer, I recommend doubling or even tripling the recipe.
