Flavor Overload – These cookies are LOADED with flavors! Hearty oats, creamy peanut butter, crunch from Reese’s Pieces, sweet chocolate chips, all in one tasty cookie. 

Pretty – Not only are these cookies insane on flavor but they are so pretty! One of my favorite fall cookie recipes for when I am serving up friends and family. 

Freezer Friendly – You can easily freeze any cookies you don’t eat right away. Just store in a freezer approved container for 3-4 months. Then thaw on the counter and enjoy. 

What Are Monster Cookies? 

Monster cookies are a peanut butter style cookie that has oatmeal, chocolate chips, and candies inside. It is almost like eating a peanut butter cookie, oatmeal cookie, and chocolate chip cookie in one. 

They are monster cause they are loaded with ingredients and you will gobble them right up. 

How to Make Fall Monster Cookies

Make Batter – The first step is mixing up the cookie batter. You will follow the steps in the recipe card below. Cream your ingredients and make sure to measure properly. 

Cookei batter with mix-in Fold In Ingredients – Then you will fold in your Reese’s Pieces and chocolate chips. Once well mixed you will then move on.

Bake – Next you will work on baking up your cookies. Leave room between cookies as they will spread a bit as they bake in the oven.

Cool and Enjoy – Place on a cooling rack once done, and then enjoy! 

Storing Cookies 

You can store your cookies in an airtight container on the counter for around 5 days. After that you will find the cookies can begin to dry out. If you plant to keep for longer, I recommend freezing.

Raw Cookie Dough 

You are welcome to freeze this cookie dough raw. You can roll the dough into a sliceable form, or you can make cookie scoops with your cookie scoop and flash freeze the dough. Then place the balls in an airtight freezer container and freeze till ready to bake. 

When you bake the raw dough, just place the frozen cookie dough on a greased baking sheet, and add a few extra minutes to allow the cookies to fully bake. 

Cooked Cookies 

If you are wanting to freeze cooked cookies simply store them in a freezer container and store for 3-4 months. Then thaw on the counter or warm them up when you want in the microwave on defrost.

Fall Monster Cookies are an easy and delicious dessert. These are loaded with oatmeal, peanut butter and Reese's Pieces. Give this easy fall cookie a try.


  • 1/2 cup salted butter, softened
  • 1/2 cup packed brown sugar
  • 1/4 cup granulated sugar
  • 3/4 cup creamy peanut butter
  • 1 large egg
  • 1 teaspoon pure vanilla extract
  • 1/2 teaspoon baking soda
  • 1 and 1/4 cups all-purpose flour
  • 1/2 cup quick oats
  • 3/4 cup Reese's Pieces
  • 1/2 cup semi-sweet chocolate chip


  1. Preheat oven to 350°F. Line baking sheet with parchment paper. In a large bowl, cream the butter and all both types of sugar together with a mixer on medium speed for about 2-3 minutes.
  2. Mix in the peanut butter, egg, and vanilla. Slowly mix in the baking soda and flour. Do not over-mix.
  3. On low speed, beat in the quick oats Reese's Pieces, and chocolate chips just until incorporated. If the dough comes out too soft for your preference, you can chill it for 30 minutes, if desired.
  4. Using a small cookie scoop, place scoops of dough onto cookie sheet. Bake for 11-13 minutes. The cookies will still look a little soft, but don't worry, they will turn out great!!
  5. Slightly press down the baked cookies with the back of a spoon or spatula, since the cookies only slightly spread in the oven.
  6. Allow cookies to cool on baking sheet for 10 minutes before transferring to a wire rack. Cookies will become firm as they cool.
