General Info About Brownies

Brownies originated in the U.S. and have been a beloved dessert staple since the early 20th century. They range from cakey to ultra-fudgy, and are one of the easiest baked treats to personalize with flavors, mix-ins, or festive designs.

Frequently Asked Questions

Can I make these brownies gluten-free?

Can I skip the ganache?
