How to Make Them

This monster cookie recipe is packed with chocolate and absolutely delicious!

PREP. Prepare a cookie sheet by lining it with parchment paper or using cooking spray. Make sure the oven is preheated to 350°F.

DOUGH. Use a hand mixer or stand mixer to combine the peanut butter, sugars, and butter. Mix these together and then add the eggs and vanilla. Next, mix in the quick oats and baking soda. Finally, stir in the chocolate chips and M&M’s.

BAKE. Use a cookie scoop for regular size or an ice cream scoop for giant cookies. Drop the cookie dough onto the baking sheet. (To make them picture perfect add a few chocolate chips and M&Ms to the top of the scoops. I love this trick!)

  • Cookie Scoops: Bake for 10 to 12 minutes.
  • Ice Cream Scoops: Bake for 18-20 minutes. Be sure you do not overbake!!

Allow the cookies to cool for a few minutes before transferring them to a wire rack to finish cooling off.

Altitude. I don’t live at high altitude so I couldn’t test it, but I read that one baker uses an extra egg to help her monster cookies come out perfect.

Monster cookie Tips

This best monster cookie recipe could be filled with even more chewy mix-ins!

Shape. I did not find that these cookies spread very much. Once the dough is on the cookie sheet lightly press the dough with the palm of your hand to give them shape. This is especially helpful if you choose to make larger cookies.

If your cookies are spreading too much double-check that you are using enough oatmeal and the butter is room temperature and cool to the touch. You can also chill the dough for 20-30 minutes before baking.

Prep the pan. Be sure to spray the cookie sheet, line it with parchment paper, or use a silpat mat.

Other mix-ins. We like using chocolate chips and plain M&M’s, but you can use your favorite mix-ins such as raisins, craisins, white chocolate or butterscotch chips, Reese’s Pieces, or mini M&M candies.

Be cautious to not add too many mix-ins otherwise, there will not be enough dough to hold it all together.

Storing Info

Store the dough. Cover the bowl of dough and keep it in the fridge for 1-2 days. For longer storage flash freeze the balls of dough and store them in a Ziploc bag in the freezer for 1-2 months. Thaw for 20-30 minutes before baking them.

Store baked cookies. Allow the cookies to cool completely before storing them. Keep in an airtight container for 1 week. Place a piece of white bread in the container to help keep them soft and fresh. These Monster Cookies can also be stored in the freezer for up to 6 months.

Recipe FAQ

Can I make monster cookies using natural peanut butter?

The peanut butter is the “glue” that holds these cookies together. For the best result use regular peanut butter such as Jif or Skippy. You can try almond butter or natural peanut butter, but the result may be a dry crumbly cookie. You can also use regular crunchy peanut butter for a bit of texture.

What oats do I use to make monster cookies?

I used quick oats because I like the texture and structure that it creates within the cookie. You can use regular oats if that is what you have on hand but do not use steel-cut oats or instant oats.

Are oatmeal monster cookies gluten-free?

These cookies are made without using flour. However, you need to check the other ingredients, like the oats, to be sure they do not contain hidden gluten.
