Monster Cookies


In case you didn’t know, I am a cookie monster. And I promised to post more cookies on this blog. So here goes: Monster Cookies!

Monster-CookiesMonster cookies are the epitome of childhood for me. M&Ms, chocolate chips, peanutbutter, and oatmeal. Can’t beat that. And as children are usually too impatient and because these do need to chill for a little bit so that you can form them into balls, I will keep it short today. Just go and make them.


Monster Cookies

Serves: 24-30 cookies, depending on size
Cooking Time: 20min preparation+ 12min of baking time

This is an oatmeal cookie with peanut butter, chocolate chips and M&Ms and evokes childhood memories.


  • 220 grams of butter at room temperature
  • 130 grams regular of sugar
  • 100 grams of brown sugar
  • 2 eggs
  • 200 grams of peanut butter
  • 2 teaspoons of vanilla extract, see here how to make your own
  • 180 grams of all-purpose flour
  • 1 teaspoon of baking powder
  • 1 teaspoon of baking soda
  • 180 grams of rolled oats
  • 180 grams of M&Ms
  • 180 grams of chocolate chips



Cream the butter with the sugars until fluffy and creamy, takes a few minutes. Add the eggs, peanut butter and vanilla extract and cream for another few minutes. Add flour, baking powder and baking soda and mix on low until combined. Add the oats, M&Ms and chocolate chips on low until combined and let chill for about 30minutes and it is possible to form the dough into balls.


Line a baking sheet with parchment paper and preheat oven to 180 degrees Celsius.


Take one to two tablespoons per cookie and roll into a ball. I press them down slightly as they don't spread much. Place about 9-12 cookies on a baking sheet and bake for about 12 minutes, the center will still look very soft. If desired, add more chocolate chips and M&Ms for nicer looks and while the cookies are still soft.


You need to be sure that the butter and egg are at room temperature. This is really important. If you forgot to take out either on time, place the egg in warm water for a few minutes and cut the butter into 4-5 pieces. Cover the butter pieces with a mug you previously had filled with boiling water. Obviously you should discard the water before placing the mug on the butter pieces.

So which cookie is your childhood’s favorite?
