What You'll Need
This cookie monster cookies recipe uses simple pantry ingredients that come together quickly. No chilling required, no fancy equipment needed. The measurements are in the recipe card below.
Main Ingredients
- 1½ cups creamy peanut butter
- 1 cup packed brown sugar
- ½ cup granulated sugar
- 3 large eggs
- 2 teaspoons vanilla extract
- ½ cup (1 stick) butter, softened
- 2 teaspoons baking soda
- 4½ cups old-fashioned oats
- 1½ cups chocolate chips
- 1½ cups M&Ms candies
- Flaky sea salt for sprinkling (optional)
Optional Extras
You can add white chocolate chips, butterscotch chips, or even coconut flakes if you want.
Some people love throwing in chopped peanuts or pretzels for extra crunch.
How to Make Jumbo Monster Cookies
Mix Wet Ingredients
Preheat your oven to 350°F. In a large mixing bowl, beat together the peanut butter, brown sugar, granulated sugar, and softened butter until smooth and creamy, about 2 minutes. Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.
Add Dry Ingredients
Add the baking soda directly to the peanut butter mixture and mix until combined. Gradually stir in the oats until everything is well incorporated. The dough will be thick and a bit sticky.
Fold in the Good Stuff
Gently fold in the chocolate chips and M&Ms, reserving about ½ cup of each to press on top of the cookies before baking. This gives them that bakery-style look.
Q: Can I make small batch monster cookies instead?
Absolutely! Just cut the recipe in half and you'll get about 12 regular-sized cookies. The baking time stays the same since these are thick cookies. This recipe is super flexible for mini monster cookies too.
Scoop Large Portions
Using a large cookie scoop (about ¼ cup), drop dough onto a parchment-lined baking sheet, spacing them about 3 inches apart. These are jumbo cookies, so they spread quite a bit. Press a few extra chocolate chips and M&Ms on top of each cookie.
Bake Until Golden
Bake for 12 to 15 minutes, or until the edges are golden brown but the centers still look slightly underdone. They'll continue to cook on the hot pan after you remove them from the oven. Sprinkle with flaky sea salt if desired.
Cool and Enjoy
Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack. This helps them set properly without breaking. Enjoy them warm with a cold glass of milk.
Aliana's Top Tip
Don't overbake these best monster cookies ever! They should look slightly underdone in the center when you take them out.
They'll firm up as they cool but stay perfectly soft and chewy inside.
If you bake them until they look done, they'll end up hard and crunchy instead of that amazing soft monster cookies texture we're going for.
Also, use a cookie scoop for uniform size so they all bake evenly.
Ingredient Substitutions & Variations
You can swap peanut butter for almond butter or sunflower seed butter if you have allergies. For healthy monster cookies, use coconut sugar instead of white sugar and add in some protein powder. If you want flourless monster cookies with even more protein, try protein monster cookies by adding ½ cup of vanilla protein powder. You can also make these as frozen cookie dough balls and bake them straight from the freezer (add 2 extra minutes to baking time).
Storage & Reheating Instructions
Store homemade monster cookies in an airtight container at room temperature for up to one week. They stay incredibly soft if you add a slice of bread to the container. You can also freeze baked cookies for up to three months, or freeze the dough balls and bake them fresh whenever you want. These frozen cookies are perfect for when you need a quick treat.
