How to Make Monster Cookies
-
Preheat & Prepare: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or Silpat mats to prevent sticking and ensure even baking.
-
Creaming: In a large mixing bowl, cream together sugar, brown sugar, and butter until the mixture is light and fluffy. This step ensures a delightful texture in your Monster Cookies!
-
Mixing in Ingredients: Add the large eggs one at a time, mixing well after each addition. Then, incorporate the peanut butter, vanilla extract, baking soda, and salt until everything is fully blended into a smooth dough.
-
Combining Oats and Mix-Ins: Stir in the oats until evenly distributed. Next, gently fold in the mini M&Ms and chocolate chips, making sure they’re scattered throughout the mixture for that delightful chocolatey burst in every bite.
-
Scoop & Bake: Scoop 2–3 tablespoon mounds of dough onto the prepared baking sheets, spacing them at least 2 inches apart to allow for spreading. Bake for 12-15 minutes, or until the cookies are golden brown around the edges but still soft in the center.
-
Cooling: Once baked, remove the cookies from the oven and let them cool on the baking sheets for 5-10 minutes. Then, transfer them to a wire rack to cool completely for that perfect chewy texture.
Optional: Drizzle with chocolate or sprinkle with sea salt for an added touch.

Monster Cookies Recipe FAQs
What type of oats should I use for Monster Cookies?

How should I store Monster Cookies?
You can store the cookies in an airtight container at room temperature for up to a week. To keep them fresh even longer, refrigerate them for up to 2 weeks. Just make sure they are well-wrapped to prevent drying out!

Absolutely! You can freeze your baked Monster Cookies in an airtight container or freezer bag for up to 3 months. When you’re ready to enjoy them, simply thaw at room temperature, or reheat in the oven at 350°F (175°C) for about 5–7 minutes for that fresh-from-the-oven taste.
What if my cookies are too crumbly?
If your Monster Cookies turn out crumbly, it could be due to too much flour or not enough moisture. Make sure to measure your ingredients accurately. Adding a little more peanut butter or an extra egg can help bind the mixture for a chewier outcome.
Can I make these cookies vegan or with allergy-friendly swaps?
Definitely! For a vegan version, you can replace the eggs with flax eggs (1 tablespoon ground flaxseed mixed with 2.5 tablespoons of water equals one egg). Also, choose a plant-based butter and ensure your chocolate chips are dairy-free. The beauty of these Monster Cookies is their flexibility to accommodate various dietary needs!
Are these Monster Cookies safe for pets?
While they are delicious for humans, remember that chocolate and certain ingredients, like peanut butter with xylitol, can be harmful to pets. Always keep treats like Monster Cookies safely out of reach of your furry friends!
