3 large eggs

1 cup sugar, sifted

1 cup brown sugar, sifted

8 ounces melted butter

1 1/4 cups cocoa, sifted

2 teaspoons vanilla extract

1/2 cup flour, sifted

1/2 teaspoon kosher 

Preheat oven to 300 degrees. Butter & flour an 8” square pan

In a mixer fitted with a whisk attachment, beat the eggs at medium speed until fluffy & light yellow

Add both sugars

Add remaining ingredients & mix to combine

Pour the batter into a greased and floured 8-inch square pan and bake for 45 minutes

Check for doneness with the tried-and-true toothpick method: a toothpick inserted into the center of the pan should come out clean

When it’s done, remove to a rack to cool

Resist the temptation to cut into it until it’s mostly cool.
