Yes, I am still making new variations of my favorite chewy chocolate chip cookies. All I did to make these mad scientist Halloween chocolate chip cookies was to add mad scientist M&Ms and a mad scientist mix of sprinkles. Does it require it’s own blog post? Probably not, but sometimes seeing is believing when it comes to recipe modifications. I already did one for the winter holidays, so why not Halloween?

If you cannot find the specific “mad scientist” M&Ms to make these Halloween chocolate chip cookies, you can obviously use whatever festive mix they are selling this year. Same goes for the sprinkles. Mine had eyes and fingers mixed into the orange, green, purple, and white jimmies but any festive combo will do.

Now that my favorite chewy chocolate chip cookies are dressed up for Halloween, I need to decide on a costume for myself. I spent so much time decorating the inside and outside of our house that I forgot to ponder costume ideas.

At one point I suggested Jean and Gene from The Umbrella Academy Season 4 for Bob and I, but I feel like I can do better. I bet there will be plenty of Australian break dancers and Beetlejuice people already. Maybe Inside Out 2 characters?

6. Place cookie dough onto the prepared cookie sheets, about 2 inches apart.
7. Bake for 10-12 minutes (will look underbaked). Cool on baking sheets for 10 minutes before transferring to wire racks to cool completely. Store at room temperature in an airtight container.

Notes

*Can add extra on top once dough balls formed. **For smaller cookies, roll 2 Tablespoons and bake for 8-9 minutes.
