Halloween food is so fun to make and the following Halloween cookies recipe idea is so easy and quick.

How to make black colored food without food coloring
Adding black coloring to baked goods like these Halloween cookies is simple, just add black cocoa powder! Black cocoa powder is what gives Oreos their black color. So cookies, cakes, and desserts made with black cocoa powder will have a similar flavor base to Oreo cookies. The black cocoa has a different flavor than regular unsweetened cocoa powder, so it definitely adds depth and a unique taste to recipes that use black cocoa powder.


Halloween Cookie Dough
This Halloween cookie dough also has a touch of dry milk powder. What does dry milk powder do in cookies? It enhances the loft and chewiness of these Halloween cookies, and also enriches the flavor of the black cocoa powder.
For these chewy black velvet chocolate cookies, I used a combination of granulated and dark brown sugar. The sugar combination provides maximum chew and a mellowed sweetness level that is perfect for adding in sweet halloween candy and chocolate chips.
These black cocoa cookies are a very easy Halloween treat idea and take under 30 minutes to make! This is a very versatile cookie dough that you can use for any mix ins you would like and change the cookies to fit any holiday or occasion.
Thanks for baking my Halloween cookies recipe!
