Halloween Monster Cookie
- When making the Halloween version - swap out the M&M's and replace the chocolate chips with the candy corn.
- Add the eyes and additional candy corn after baking.
Notes
- I’m using Halloween-colored M&Ms, but feel free to use any add-ins you like.
- If you add candy corn to the cookie dough, make sure they are fully encased in the
dough when you bake them or they’ll melt in the oven. I recommend adding them on top of the cookies if you want to keep the shape. - Candy eyes add a fun Halloween twist as well, but they are completely optional! Just make sure to press them into the cookies while they’re still warm so they stick
