This classic Monster Cookies recipe with peanut butter, oats, chocolate and M&MS’s gets a Halloween makeover with the addition of candy eyes and colorful sprinkles!
As you can see below, they can also be made without the candy eyes, and with any color of M&M’s that you have on hand!
Have you ever wondered why Monster Cookies do not normally have eyes? I decided that they should, but I promise that they are soft and delicious either way!
I also decided that they needed colorful jimmies sprinkled all over them to make them look even more festive.
There’s just something soothing and magical about the combination of peanut butter and chocolate, wouldn’t you agree?
Recipe ingredients:
- Monster Cookies are pretty much a peanut butter cookie mixed with oats, chocolate chips and M&M’s.
- The base cookie is made with softened butter, egg, pure vanilla extract, brown sugar, granulated sugar, salt, baking soda, and flour.
- The candy eyes and colorful sprinkles make them fun and festive, but both are completely optional.
How to make easy Monster Cookies:
Preheat oven to 350 degrees. Line 3 baking sheets with parchment or silicone liners, set aside.
In a large bowl, beat the butter and peanut butter together to combine.
Add the egg, vanilla, and sugars and beat until light and creamy.
Add the flour and baking soda and beat just until combined.
Stir in the oats, chocolate chips, and M&M’s.
Scoop the dough and place on prepared baking sheets. I used a #30 {2 tablespoon} sized scoop.
Lightly press to flatten cookies. Top with candy eyes, additional M&M’s and sprinkle with colorful sprinkles.
Bake for 10 to 12 minutes. Cookies with be slightly browned along the edges, but still soft in the center. Remove from oven and allow to cool on the baking sheet for 5 minutes before moving to a wire cooling rack.
Be very careful when moving the cookies, they will break apart while they are still hot. These Monster Cookies are super soft and perfect with a glass of ice cold milk {non-dairy of course}.

Recipe Notes & Tips:
- All ovens bake differently, cooking times are approximate. Mine were done in 11 minutes.
- I only had old-fashion oats in the pantry (last time), which gives these cookies a bit of a crunch. I used quick oats this time and they just disappear into the cookie.
