Ingredients

Ingredients for Monster Cookies - butter, peanut butter, brown sugar, eggs, vanilla, baking soda, oats, chocolate chips, M&M's.
  • Butter. Softened at room temperature.
  • Peanut Butter. Creamy peanut butter is what I prefer. I like Jif or Skippy.
  • Brown sugar. The Best Brown Sugar Substitutes
  • Eggs. I used large eggs.
  • Vanilla extract. Use pure vanilla extract.
  • Baking soda. Best Baking Soda Substitutes
  • Old Fashioned Rolled Oats. Make sure to use old fashioned oats and not quick cooking.
  • Semi-sweet chocolate chips. Semi-sweet helps to cut down on sweetness.
  • M&M’s. You can change these and use seasonal M&M’s all year long.

Find the complete list of ingredients at the bottom of the page.

Substitutions and Additions

  • Dairy-free. If you need the cookies to also be dairy free, substitute ghee for the butter. You will also need to substitute the chocolate for a dairy free candy.
  • Nut Butter. You can substitute the peanut butter for sunflower seed butter.

Step By Step Instructions 

  • Step 1. First, preheat the oven to 350 degrees. Then line 2 baking sheets with parchment paper. 
Peanut Butter creamed together in a bowl.

Step 2. Get out a large mixing bowl and blend together the unsalted butter, creamy peanut butter, brown sugar and granulated sugar. You can use a stand mixer or hand mixer. Next, add in the eggs and vanilla extract.

Oats added to mixture.

Step 3. Next, add in the baking soda and rolled oats to the cookie dough.  Make sure to stir in by hand or on a low speed with your mixer until the oats are combined. The dry ingredients and wet ingredients should be well combined.

M&M's folded into dough.

Step 4. Then stir in the chocolate chips and M&Ms.

Step 5. Form the cookies. I like to use a medium cookie scoop to scoop the mixture into balls. Then place the cookie dough balls on the baking sheets.

Step 6. The cookies need to bake for 12-15 minutes. The edges should start to brown, and the center of the cookies are just set but still look soft. 

Cookies on wire rack.

Step 7. After the cookies have cooled about 10-15 minutes on the baking sheet, move to a wire rack. Allow to cool completely.

Storage

Store leftovers in an airtight container at room temperature for up to 1 week.

Pro Tips

  • Peanut Butter. Do not use all-natural peanut butter for this recipe as it will separate and not hold the cookies together.  
  • Stir in the oats by hand or use low speed. Be careful with the oats and don’t use a mixer on high.
  • Don’t overcook the cookies. They will continue to cook on the baking sheet, and you don’t want to overbake them.
  • Use Old Fashioned Oats. You can try using quick oats, but the cookies will not be as chewy, and they won’t spread as much.
  • Certified Gluten-Free Oats. While oats are naturally gluten free, they can be packed in a facility with gluten. If you have dietary restrictions, it is important to look for oats that are certified gluten free.
