Why You Must Make

The date on this original post was December, 2010. My college senior was still in high school and my food photography was marginal at best. And worst of all, I have made so many brownies since this post, I had no recollection of these Fat Witch brownies. Well, one slice into these gems revealed exactly what I’d hoped for: fudgy brownies with an amazing chocolate aroma. Whew.
This is a copycat recipe of a yummy brownie from New York City’s Fat Witch Bakery.
I finally got back to this recipe in 2025. And they again got rave reviews from the family.
Plus, they’re easy to make, rich and delicious!

Ingredient Notes

Kitchen Staples – Sugar, All-Purpose Flour, Salt
Butter – I used salted butter.
Eggs – Have them at room temperature for easier incorporation.
Vanilla Extract – Use real vanilla extract, not artificially flavored, for the best results. I use the Nielsen-Massey brand.
Bittersweet Chocolate – I used a Ghirardelli bar. They can be found in the baking aisle of most larger supermarkets.

How to Make

Line 9 x 9-inch baking pan with nonstick foil.

Expert Tips

Use a bittersweet chocolate bar instead of chips for the brownie batter. The flavor is better and they melt wonderfully. I keep quite a stash of Ghirardelli bars in my pantry for just such occasions. If you only have chocolate chips, use a kitchen scale to weigh out 4 ounces. I used chocolate chips when I made my first batch in 2010 and they were perfectly delicious.
I also upped the vanilla a bit from 1 teaspoon to 1 ½ teaspoons.
The first time I made these, I chopped up a couple of Heath bars and added them to my half of the brownies, knowing the rest of the family wouldn’t be thrilled with the toffee bits as much as I would! You could also add chocolate chips or nuts to the batter if you’d like.
Cut these brownies into large bars and top with a scoop of ice cream for an elegant brownie sundae or slice into smaller servings for those mid-day chocolate cravings. My original post is below with a photo of my furry buddy, Lambeau. I hope you have the chance to bake up a batch soon.

Frequently Asked Questions

What Are Fat Witch Brownies?

Fat Witch Brownies are a popular brownie from the Fat Witch Bakey in New York City’s Chelsea Market. A variety of their brownies are also offered via their online store.

How Can You Tell Whether a Brownie will be Fudgy or Cakey?

Check out the fat-to-flour ratio. The fat is usually butter, but occasionally oil. There should be more fat than flour in a fudgy recipe. A cakey brownie has more flour than fat, often with a leavening agent like baking powder.
