...Now let's hope this package makes it to its destination safe and sound...
4 large eggs
7 ounces (~1 cup) granulated sugar
7 ounces (~1 cup) brown sugar
3 3/4 ounces (~1 1/4 cups) cocoa powder
2 3/8 ounces (~1/2 cup) all-purpose flour
1/2 teaspoon kosher salt
2 teaspoons vanilla extract
8 ounces (2 sticks) unsalted butter, melted
Preheat oven to 300° F. Spray an 8"x8" pan (preferably glass) with non-stick spray.
In a large mixing bowl, whisk together the eggs for about 30 seconds. In another bowl, sift together the sugars, cocoa, flour, and salt. Slowly incorporate the dry ingredients into the eggs. Once incorporated, add the vanilla and gradually whisk in the melted butter.
Transfer the brownie batter to your greased pan, and bake for 45 to 55 minutes, or until a toothpick comes out almost completely clean. Let the brownies cool on a cooling rack for at least an hour before serving.
