To the right of the cookie stack is a red and white napkin that runs toward the back left of the frame where there is a glass jar of milk with a candy cane in it. In front of the milk jar and to the left of the cookie stack is a fudgy peppermint chocolate cookie with a bite taken out of it.

How to prepare your pan

Line two cookie sheets with a silicone mat or parchment paper.  If you don’t have two cookie sheets, one is fine too!

How to make Fudgy Peppermint Chocolate Cookies

Combine the melted butter with the sugars, then stir in the eggs and vanilla. Then add the flour, cocoa powder, cornstarch, baking powder, and salt, and mix till combined. Lastly, stir in the peppermint chips. It’s best if you can refrigerate the dough for at least 30 min – 1 hour, but it will still taste great if you don’t.  The time in the refrigerator will allow the flavors to meld, and also makes the dough a bit firmer so that it holds its shape a bit more and doesn’t spread too much.

Once it’s chilled form balls of dough, about 1 tablespoon, and place on the baking sheet a couple inches apart.  If you’ve chilled the dough, using your palm, slightly flatten each dough ball into a thick disc.  Bake at 325 F for about 10-12 minutes, until the dough not longer looks wet. Let the cookies cool for about 5 minutes on the pan, and then move to a wire rack to cool completely. But I won’t tell anyone if you sneak a warm cookie straight out of the oven – just be careful!

I like to use two baking sheets so that when one pan is baking, the other one can cool for a few minutes, and then I can put new balls of dough onto the pan once I move the cooled cookies to the wire rack so that once the ones in the oven come out, I can put the other sheet back in.

Common Questions

Why did my cookie not flatten?

This recipe is not designed for the cookie to spread much, however if you don’t refrigerate it before baking, the dough may spread more and you may not need to flatten it with your palm.  If you refrigerate the dough, you definitely will want to flatten it a bit before baking.

What makes a cookie chewy?

There are a lot of ways to make chewy cookies.  In this case, the combination of using brown sugar and melted butter are keys to ensuring a chewy cookie.

What happens if you don’t put eggs in cookies?

Eggs help hold all the ingredients together and helps the cookies hold their shape.  They also add moisture to the batter which helps make the cookies chewy. If you want to skip eggs, check out my Substitutions Guide for ingredients to use in place of eggs. Please note, I have not specifically tested these substitutes for this recipe, but these are substitutes that generally work for various ingredients.  Try at your own risk – the recipe has only been tested as it is written!
