Why Are Monster Cookies Called Monster Cookies?

Some Say Monster Cookies get their name from this intentional mash-up concept of pulling parts from different recipes to make a Frankenstein-like cookie.

However the original creator, stated his Monster Cookies refer to a cookie recipe that continually changed over time.

No matter why they are called Monsters Cookies these soft chewy treats have all the flavors we love and an unbelievable texture.

Is There Flour in Monster Cookies?

Yes and no. The original monster cookie recipe did not contain wheat flour, because the creator did not have any on hand.

However, as the recipe has morphed over the years, bakers have found a little flour makes a big difference in the recipe. It offers a softer fluffier texture, than oats alone.

Gluten Free Monster Cookies

Yet since it’s only a little flour, Monster Cookies (in my opinion) are the best cookies to convert to Gluten Free.

They taste and feel exactly the same with gluten free baking powder.

If you are very sensitive to gluten, it should be noted that it’s best to check all the ingredients for hidden gluten, or to make sure they were not processed in a facility with wheat products… Chocolate chips, oats, etc. (Classic M&Ms are gluten free!)

How Do You Make Monster Cookies?

  1. To make The Best Monster Cookies Recipe, start by mixing the oats with eggs, vanilla, and a little water. This helps moisten the oats before they are mixed into the dough.
  2. Cream the butter, peanut butter, and sugars together until light and fluffy. This usually takes a few minutes, but makes a big difference in overall texture.
  3. Mix in the dry ingredients. Then add the softened oat to the mixture as well.
  4. Then finally mix in the chocolate chips and M&Ms.
  5. Use a big scoop to portion out the cookies so they are monster-size.

How Do You Make Gluten Free Monster Cookies?

All you have to do is swap wheat flour for gluten free flour!

Can I Make A Dairy Free (or Vegan) Version of Monster Cookies?

It’s very easy to swap the butter for vegan butter in this recipe. However, to be fully dairy free and vegan, you will also have to use vegan chocolate chips and chocolate candies.

How Long Do Monster Cookies Last?

Well, that depends on how many cookie monsters you have in your house. One day in my house! However, you can keep them in an airtight container at room temperature for up to 10 days.

Can You Freeze Monster Cookies?

Yes. It’s best to freeze the dough rolled into a log shape, than to freeze baked cookies. Later you can either thaw the dough and bake the cookies, or break off pieces of the frozen dough and bake the cookies a few minutes longer than normal.

How Do I Make Pretty Monster Cookies?

I like to reserve some of the M&Ms to pretty-up my cookies before they go in the oven. Pay attention to what you see on top of each dough ball. Then add extra M&Ms where needed.

  • Preheat the oven to 350 degrees F. Line several baking sheets with parchment paper and set aside.
  • In a large bowl, measure out the oats. Then crack the eggs into the oats and add the water and vanilla. Stir to coat, allowing the liquid to saturate the oats.
  • In the bowl of an electric stand mixer, add the butter. Beat 1 minute to soften. Then add in the peanut butter, and both sugars. Beat on high for 3-5 minutes to break down the sugar crystals.
  • Scrape the bowl with a spatula, and beat again to incorporate.
  • Turn the mixer on low and mix in the flour, baking powder, and salt. Once fully mixed in, start adding in the oat mixture.
  • Scrape the bowl again, then turn on low and mix in the chocolate chips.
  • Finally mix the M&Ms into the dough with the spatula.
  • Use a large 3 tablespoon cookie scoop to portion the cookie dough onto the prepared baking sheets. Space the cookies 2 inches apart.
  • Bake for 15-17 minute per batch, until the edges are just barely golden brown. Cool 3 minutes on the baking sheets before moving.



Pro Tip: Reserve 1/3 cup M&Ms to press on the top of the cookies, so they look pretty once baked.
Gluten Free! This is one of the easiest recipes to convert to GF, because there is so little flour required. They taste and feel exactly the same! Just swap the wheat flour for GF baking mix, and make sure your oats are processed in a GF facility.
