Notes
*This recipe was written using an average of the dip and sweep method for measuring flour and the spoon and level method. If you are using a scale, you will need to add 3/4 oz or 22 gto the measurement for each cup of flour.Substitutions:
Semi-sweet can be used in place of bittersweet chocolate, but the brownies will be a lot sweeter.
Expert Tips:
Make sure to beat the eggs, sugar, and vanilla for a full 10 minutes!
If you do not use a bake-even strip, the brownies will be more traditional. Crispy edges and fudgy middle.
These brownies are very fudgy. If you like them a little more done, leave in an additional 5 minutes.
