Snickers Monster Cookies

by Kristen

M&M’s aren’t the only candy you should bake in monster cookies!  These Snickers monster cookies are incredibly chewy, chocolatey cookie recipes that you should try!  This is a great way to use leftover Halloween candy or Easter candy!  You will wish you make a double batch of cookies after you try these!

Monster Cookies were created in 1971 by Mr. Dick Wesley, a father of six kids who liked to create recipes with the food he happened to have on hand.   When he first created the monster cookie, he was out of flour, so he added oatmeal to a mixing bowl with many other ingredients.

Traditionally, monster cookies are made with a cup m&m candies, but I encourage you to make this sweet treat with snickers candy bars!  ( or other candy bars you happen to have leftover from various celebrations your kids attend)

All you need is a few ingredients to make these cookies!


Quick Cook Oats

Light brown Sugar

Dark or Milk Chocolate Chips

Large Egg

1 cup peanut butter

unsalted butter

One teaspoon salt

One teaspoon baking soda

One teaspoon vanilla extract

Chopped Snickers Candy Bar Pieces

Optional Add-ins:  white chocolate chips, peanut butter chips, caramel chunks, dark chocolate chips, peanuts, any other candies you like.


cookie sheet or baking sheet

mixing bowl

hand mixer

parchment paper

cooling rack

My kids love oatmeal cookies!  I like to tell myself that oatmeal cookies are healthy:)  You are entitled to your own opinion, though.

This dessert recipe is such a piece of cake, and your house will smell fantastic when you take the cookies out of the oven.

Snickers Monster Cookies


  • 1 cup peanut butter creamy or chunky
  • 1 cup packed light brown sugar
  • 1/2 cup unsalted butter
  • 3 large eggs
  • 1 teaspoon vanilla extract
  • 2 teaspoons baking soda
  • 4.5 cups quick cook oats
  • 1/2 cup chocolate chips
  • 1/2 cup chopped snickers bars


  1. Preheat oven to 350 degrees

  2. Line baking pans with parchment paper or spray them with cooking spray.

  3. In a large bowl mix together peanut butter, sugar, and butter.

  4. Mix in eggs and vanilla.

  5. In a separate bowl mix together oats with baking soda.

  6. Mix in oats, followed by chocolate chips and snickers.

  7. using a cookie scoop, drop the cooking evenly onto the baking sheet. If you want to cookies to be flat, you would flatten them now.

  8. Bake 10-12 minutes.

  9. Remove from oven and let cool. Serve.


You will want to store these in an airtight container for up to five days. You can freeze them in an airtight container for up to 6 months. I like to freeze cookies in little baggies, so when we’re looking for a bit of dessert, we can take them out!
