Ingredients
Method
- Preheat oven to 350°F. Line a 9x13-inch baking dish with foil and coat with non-stick spray.
- In a mixer bowl, blend melted butter and cocoa powder until smooth.
- Add flour and sugar, mixing briefly. Add eggs and vanilla and mix just until combined. Do not overmix.
- Spread thick batter evenly into prepared pan and bake 25–30 minutes, until a toothpick comes out clean.
- Let brownies rest 15 minutes while still warm. Beat frosting ingredients until smooth and spread over warm brownies.
- Cool completely before slicing into squares and serving.
Notes
For extra richness, add chopped walnuts or chocolate chips to the batter. Frost while warm for the classic glossy finish.
