Brownie Cocoa Powder

INGREDIENTS

Soft butter, for greasing the pan

Flour, for dusting the buttered pan

4 large eggs

1 cup sugar, sifted

1 cup brown sugar, sifted

8 ounces melted butter

1 1/4 cups COCOA POWDER, sifted

2 teaspoons vanilla extract

1/2 cup flour, sifted

1/2 teaspoon kosher salt

Preheat the oven to 300 degrees F. Butter and flour an 8-inch square pan.

In a mixer fitted with a whisk attachment, beat the eggs at medium speed until fluffy and light yellow. Add both sugars. Add remaining ingredients, and 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.
