Monster Cookie Ingredients:
- Chocolate cake mix – The secret to moist, chocolatey cookies!
- Brown sugar – For a flavor that’s deeper and richer than granulated sugar.
- Butter – Make sure it’s at room temperature (but not melted) so it’s blendable.
- Creamy peanut butter – Because what goes better with chocolate?
- Whole milk – You’ll only need a couple of tablespoons but it makes a big difference to the dough and final cookie texture.
- Eggs – A binding agent that keeps everything together.
- Vanilla extract – For flavor.
- Minute oats – These make the cookies nice and dense. Be SURE to use 1-minute quick oats.
- Halloween M&M’s – Regular is fine, but Halloween is better!
- Semi-sweet chocolate chips – For more intense chocolatey flavor.
- Candy eyes – These really make the treats come alive.
- Halloween sprinkles – Fun and festive for all your Halloween recipes!
How To Make Halloween Cookies:
Preheat the oven to 350 degrees F and line a baking sheet with parchment paper and set it aside.
Mix together the cake mix, brown sugar, butter, peanut butter, milk, egg, and vanilla extract in a large bowl with an electric mixer on medium speed until fully combined.
Stir in the oatmeal, M&Ms, and chocolate chips until just combined. The dough is going to be thick.
Portion out the cookie dough with a medium cookie scoop and place the balls at least 2 inches apart on the prepared baking sheet. Then, top the cookie dough balls with sprinkles and extra M&Ms.
Bake the cookies, after the baking time is complete, add the candy eyes immediately after removing from the oven.
Expert Tip: For best baking results, bake these cookies one batch at a time on the middle rack in the oven.

How long are these Halloween Monster Cookies good for?
Substitutions & Variations:
- Chocolate chips: You can use milk chocolate, dark chocolate, white, or even peanut butter chips instead. Or, get crazy and add ¼ cup of two different kinds!
- Cake Mix: Feel free to swap out the chocolate cake mix for another flavor! I personally like chocolate, but you could use a yellow or vanilla cake mix for a more traditional monster cookie flavor.
- Reese’s Pieces: Feel free to swap the M&Ms for Reese’s Pieces for even more peanut butter flavor!
