Step 1

Preheat oven to 350°F. Grease and line a 8″x8″ pan with parchment paper and set aside.

Step 2

In a large microwave-safe bowl, combine butter and sugar. Microwave for 30 seconds, then remove and stir with a whisk. Repeat process 2 more times. Though granules of sugar will remain, the goal is to get the mixture to a glossy finish.

Step 3

Allow mixture to cool slightly, then add in eggs one at a time, whisking in between each addition. Whisk until the mixture lightens in color slightly.

Step 4

Add in cocoa powder, salt, and vanilla extract. Fold in flour until just combined.

Step 5

Pour mixture into prepared baking pan and bake for roughly 30 minutes*, testing for doneness by inserting a knife into the center of the brownies beginning at 25 minutes. You’ll know they’re done when the edge is set, but a knife inserted into the middle still comes out with a bit of brownie batter on it. It might take up to 45 minutes for them to cook through depending on your oven!
