Notes
Melting chocolate and butter in microwave is easy option. if you don't have microwave, just melt it in a sauce pan on low heat.
Once you add eggs, whisk it vigorously for at least 1 minute. Whisking eggs really well create the shiny crackly top which is characteristic of a brownie.
You could add chocolate chips or finely chopped nuts into the brownie batter.
You could skip peanut butter and make it plain fudgy brownies.
If you are using a small baking pan, then baking time may get increased.
Cool the brownies completely before slicing so the brownie gets plenty of time to set.
