Ingredients

  • 6 large eggs
  • 2 1/3 cups firmly packed light brown sugar
  • 2 cups white sugar
  • 2 sticks of butter 1/2 pound, softened to room temperature
  • 1 Tablespoon light corn syrup
  • 1 teaspoon vanilla
  • 4 teaspoons baking soda
  • 2 1/4 cups peanut butter you can use creamy peanut butter or crunchy peanut butter
  • 1 1/2 cups flour
  • 7 cups quick 3-minute oats
  • 1 1/3 cups semi-sweet chocolate chips
  • 1 1/3 cup M&M candies standard size, any color combination you want

Instructions

    Cup of Yum
  1. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius).
  2. Spray cookie sheets with nonstick spray or line with parchment paper or silicone mats. Use 4 cookie sheets to allow one set to cool while the next set is baking.
  3. Set aside 1/3 cup of the M&M's for adding to the top of the cookies later.
  4. In a large mixing bowl, combine the peanut butter, butter, white sugar, brown sugar, and corn syrup. Use an electric mixer to mix until well combined.
  5. Mix in the eggs, vanilla, baking soda, and flour.
  6. Mix in the oats.
  7. Stir in the chocolate chips and M&M's (just 1 cup, keep the other 1/3 cup for later).
  8. Make large cookie dough balls and pat them out into rounds that are about 3 1/2 inches in diameter and 1/2 inch tall. Place them on a cookie sheet with space around them to expand. You should only put 6 per cookie sheet. For the 60-minute cook time, bake 2 cookie sheets at a time.
  9. Add a few of the saved M&M's to the top of the cookies for decoration.
  10. Bake for 10-12 minutes until the edges turn golden brown. Be careful not to overbake them.
  11. Let the cookies cool for 5 minutes on the cookie sheets.
  12. Transfer to wire racks and allow them to cool completely before storing them in an airtight container with wax paper between the layers of cookies to prevent sticking.
  13. Optionally, freeze some for later.

Notes

  • Keep in mind, these substitutions can change the texture and flavor of the cookies, and the cooking time might vary. You may need to experiment to get the best results with the alternative ingredients. Also, be sure to check ingredient labels to fit your dietary needs.
  • Store leftover Monster Cookies in an airtight container at room temperature for up to a week, using wax paper between layers if stacked. They’re best enjoyed within the first three days.
  • To freeze, let the cookies cool, then store them wrapped in plastic inside an airtight container or freezer bag for up to 3 months. When ready to eat, thaw at room temperature or warm in a 300°F (150°C) oven for 5-10 minutes.
