Tips & Tricks
Brown the Butter Carefully: Watch the butter closely once it starts foaming. It can go from perfectly browned to burnt very quickly.
Cool Before Frosting: Make sure the brownies are completely cool before adding the frosting to prevent it from melting.
Don’t Overbake: Remove the brownies when the center still has moist crumbs. They will continue setting as they cool.
FAQs
How should I store frosted brownies? Store them in an airtight container in the refrigerator for up to 4 days.
Can I freeze these brownies? Yes. Freeze the unfrosted brownies for up to 2 months. Thaw completely before frosting and serving.
Why use brown butter in brownies? Brown butter adds a rich, nutty flavour that makes the brownies taste deeper and more complex than brownies made with regular melted butter.
Can I make these brownies without frosting? Absolutely. The brownies are rich and fudgy enough to enjoy on their own.
