Ingredient Notes
You just need a few ingredients to make these Halloween monster cookies.
Black Cocoa - Black cocoa is one of my favorite secret ingredients! Black cocoa is just cocoa powder that has been heavily dutched (meaning the acidity has been neutralized), so it gives you a rich black color but doesn't stain! You don't have to use black cocoa powder for these cookies, but regular cocoa just won't give you the same fun effect, so I highly recommend it! I like both the King Arthur Flour Black Cocoa or the Modern Mountain Company Black Cocoa!
Chocolate Chips - If you like dark chocolate, I highly recommend the Ghirardelli bittersweet chocolate baking chips. The flavor is amazing and the baking chips are slightly larger than normal chocolate chips and melt beautifully inside the cookies. Trader Joe's chocolate chips are also some of my faves!
Candy Eyes - These are optional, but I love adding little candy eye balls to the tops of the cookies to make them look like spooky black monsters!
The complete list of ingredients and amounts is located in the recipe card below.
How to Make Monster Cookies
Using a stand or hand mixer, cream together the softened butter, brown sugar, and granulated sugar until smooth and creamy.
Add in the eggs and vanilla extract and beat until the texture is light and fluffy (about 3-5 minutes).
Stir in the flour, black cocoa powder, baking soda, and salt and mix until thoroughly combined. The dough should be wet and sticky.
Using a spoon or spatula, gently fold in the dark chocolate chips.
Spoon a generous 3 tablespoons of dough and roll into balls. Cover the dough and chill in the fridge overnight (minimum of 2 hours if you just can't wait).
Preheat your oven to 350°F and line a light colored baking sheet with parchment paper.
Place dough balls at least 2-3 inches apart on the baking sheet (they will spread, I usually only do 5 cookies on a half sheet pan).
Bake cookies for 9-11 minute or until the edges are set and the centers are still soft.
Immediately after removing from the oven, press candy eyes all over the tops of the double chocolate cookies so that they set.
Let the cookies rest on the baking sheet for 5 minutes, then transfer to a cooling rack.
While these monster cookies are perfect for Halloween, just leave off the eyes for regular double chocolate chip cookies that you can enjoy all year long!
Why do I have to chill the dough?
Chilling the dough is super important for a few reasons!
First, letting the dough rest gives the flour time to hydrate. Eggs are the only liquid in these monster cookies and it takes flour a long time to absorb that moisture. When the flour is hydrated it helps contain the spread of the cookie so that you get a nice set edge and soft, chewy center.
Similarly, the butter needs to be as cold as possible before baking so that the cookies don't spread too much.
But don't we want the cookies to spread? Yes, we do and they will. We just don't want them to spread too much because then you get a flat, dry cookie instead of one with a soft, chewy center.
Tips for Perfect Cookies
Measure your flour correctly! It's most accurate to use a kitchen scale, but if you're measuring by volume you want to spoon and level! Fluff up the flour a bit with a spoon, and then spoon flour into the measuring cup. Once it's overflowing, use the back of a knife to level it off. Don't ever pack flour into the measuring cup or you'll end up with way too much! Improperly measured flour can lead to dry, crumbly cookies that don't spread.
Make sure your oven is the proper temperature! Use an oven thermometer to make sure your oven is exactly 350°F. If the oven is too cold, the cookies will spread too much and if it's too hot they centers won't bake all the way through. For example, my oven is about 20 degrees off. So I have to set the oven to 370°F in order to get it to bake at 350°F.
Use a lightweight, light colored baking sheet for best results! Believe it or not, a lighter pan makes the cookies bake more slowly than a dark pan, which helps keep them from spreading too much. My favorite pans for baking cookies are:
You also want to use either parchment paper or silicone mats on your cookie sheet to help keep the cookies from spreading.
Bake the cookies one sheet at a time, on the center rack. This will ensure all your cookies cook evenly and the bottoms don't burn. Then let the cookie sheet cool completely between batches. This ensures the cookies cook evenly and don't spread too much by being put on a hot pan.
Always under-bake the cookies! If you slightly under-bake the cookies (so the centers are still soft when you remove them from the oven), they'll stay soft and chewy for days!
Do the cookie scoot! In order to get perfectly round cookies, use a large cookie cutter to gently scoot them around as soon as they come out of the oven!
Cookie Baking Tools
Recipe FAQ's
Store the baked black cocoa cookies in an airtight container at room temperature for up to 4 days. You can also store the dough in the fridge for up to a week and bake a few cookies at a time, as desired.
Yes! Freeze the pre-rolled cookie dough balls on a baking sheet, once frozen transfer to an airtight container and freeze for up to 6 weeks. The frozen cookie dough can go straight from the freezer to the oven, just add 2-3 minutes to the cooking time.
I recommend using black cocoa powder if you can find it for a fun, spooky black color, but you can use dutch cocoa powder instead!
Tips for Success!
For best results I always recommend using weight measurements (especially when baking) because it's the most accurate. Kitchen scales are super affordable and also reduce the number of dishes you have to do! However, all my recipes also include US customary measurements for convince. Use this chart to convert measurements for common ingredients!
Substitutions: In all my recipes, I've included substitutions that I know will work, but I cannot guarantee results if you substitute ingredients that I have not recommended. [For example, granulated sugar and honey are indeed both sweeteners but they have very different properties so they can not always be swapped 1:1. Using honey in a cookie recipe that calls for granulated sugar will yield a giant mess.] In the recipe card you'll find links to the specific ingredients/brands that I use.
A note on salt: I almost exclusively use Diamond Crystal Kosher Salt because it's the best all-purpose salt for cooking and baking. If you're not using kosher salt, consult this handy guide for a conversion chart! When in doubt, if you're using table salt just reduce the amount by half for baked goods. When cooking, I prefer to under-salt because you can always add more! If you've over-salted, adding a little bit of acid (like lemon juice) can help.
