Preheat oven fully to 350°F. Grease a 13x9-inch pan. (We use a non-stick cooking spray.)

Mix softened butter with the cocoa in a bowl.

In a separate large bowl, whisk the eggs. Then whisk in the sugar and vanilla.

Add the butter and cocoa mixture to the large bowl. Mix all ingredients until combined.

Now add flour, salt and baking powder to large bowl. Stir until combined. Do not overmix.

Pour batter into a 13x9-inch greased pan. Bake on middle rack in oven for 25 minutes. Allow to cool in pan before cutting into bars.

Be careful not to overbake! Even if it looks like it’s not quite done, it will harden in the pan.

Store by wrapping with plastic wrap so they don’t dry out.

Or, freeze brownies individually in ziploc bag (squeeze out air). Warm back up or freshen by heating up in the microwave.
