How to Make Monster Cookies – Step by Step

Step 1: Prepare Your Baking Sheets

Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper or silicone baking mats for easy cleanup.

Step 2: Mix the Wet Ingredients

In a large bowl, combine the peanut butter and softened butter. Use an electric mixer on medium speed to beat until smooth and well combined, about 1 minute. Add both sugars and continue beating until the mixture is light and fluffy, about 2 minutes more.

Step 3: Add Eggs and Flavoring

Add the eggs one at a time, mixing well after each addition. Beat in the vanilla extract until fully incorporated. The mixture should be smooth and creamy.

Step 4: Incorporate Dry Ingredients

Sprinkle the baking soda and salt over the wet mixture. Mix until combined. Add the oats one cup at a time, mixing at low speed between additions to prevent oats from flying everywhere.

Step 5: Fold in Mix-ins

Gently fold in the M&Ms and chocolate chips using a rubber spatula. For how to customize Monster Cookies for holidays, use seasonal colored M&Ms or themed candy pieces.

Step 6: Scoop and Bake

Using a 2-tablespoon cookie scoop or spoon, drop dough onto the prepared baking sheets, spacing cookies about 2 inches apart. These Monster Cookies spread during baking.

Bake for 10-12 minutes until the edges are set but the centers still look slightly underdone. This is key for how to make chewy Monster Cookies from scratch.

Step 7: Cool and Enjoy

Allow cookies to cool on the baking sheets for 5 minutes before transferring to a wire rack to cool completely. They will firm up as they cool.

Pro Tips for Making the Best Monster Cookies

When it comes to baking tips for perfect Monster Cookies, these insider secrets make all the difference:

1. Don’t overmix the dough once you’ve added the oats. Overmixing can make your cookies tough instead of chewy.
2. Chill the dough for 30 minutes before baking if you want thicker cookies that spread less.
3. Underbake slightly for that perfect chewy texture. When you remove them from the oven, they should look slightly underdone in the center.
4. Mix up your add-ins based on what you have available. These cookies are incredibly versatile – try different favorite toppings for Monster Cookies like peanut butter chips, crushed pretzels, or toffee bits.
5. For easy Monster Cookie dessert ideas, press slightly cooled cookies around scoops of vanilla ice cream to make incredible ice cream sandwiches.
