Ingredients

  • 1 lb. margarine
  • 1 Tbsp. light Karo syrup
  • 2 lb. brown sugar
  • 4 c. white sugar
  • 3 lb. peanut butter
  • 12 eggs
  • 1 Tbsp. vanilla
  • 18 c. oatmeal
  • 8 tsp. soda
  • 1 lb. chocolate chips
  • 1 lb. M & M candies

Instructions

  1. Cream margarine, light Karo syrup, brown sugar, white sugar, peanut butter, eggs, and vanilla until smooth.
  2. Add oatmeal, baking soda, chocolate chips, and M&M candies to the mixture.
  3. Mix well until evenly combined.
  4. Drop large tablespoons of dough onto a cookie sheet and flatten slightly.
  5. Place about 6 cookies per sheet.
  6. Bake at 350°F for 10 to 12 minutes, ensuring not to overbake.

Tips & Substitutions

For a slightly healthier option, you can substitute half of the margarine with unsweetened applesauce. If you're looking for a gluten-free version, use certified gluten-free oats. To keep your cookies chewy, ensure you don't overbake them; they should be just set in the center when you take them out of the oven. Mixing in some chopped nuts can add a delightful crunch.

Serving Suggestions

These Montana Monster Cookies are perfect for parties or as a sweet treat after a meal. They pair beautifully with a glass of cold milk or a warm cup of coffee. For a fun dessert platter, consider serving them alongside Valerie'S Hot Cheese And Artichoke Hearts or other finger foods. They also make great snacks for kids’ lunchboxes.

Storage & Reheating

Store leftover cookies in an airtight container at room temperature for up to a week. For longer storage, freeze them in a single layer on a baking sheet, then transfer to a zip-top bag, where they can last for up to three months. To reheat, simply pop them in the microwave for a few seconds or warm them in an oven at 300°F for a few minutes.

Frequently Asked Questions

How do I adjust the baking time if using a convection oven?

If using a convection oven, reduce the baking temperature by 25°F and check for doneness a few minutes earlier than the recipe suggests. The circulating air cooks the cookies more evenly and can lead to a quicker bake.
