Best gooey brownies

 Ingredients:

1 1/4 cups sifted all-purpose flour (285 gr)

1 teaspoon salt 

8 ounces unsalted butter  (225 gr)

6 ounces dark chocolate, coarsely chopped (170)

2 cups sugar  (450 gr)

1 teaspoon vanilla extract 

4 large eggs

1 tsp cinnamon

Powdered sugar (enough to sprinkle brownies)

To make:

1. Preheat the oven to 350°.

2. Sift the flour and salt together and set aside.

3. Melt the butter and chocolate together in double boiler pot, stirring frequently. Add 1 cup of the sugar to the mixture and stir for half a minute, then remove the pan from the heat and stir in the vanilla.

4. Pour the mixture into a large bowl.

5. Put the remaining 1 cup sugar and the eggs into a bowl and whisk with an electric whisk just to combine.

6. Little by little, pour half of the sugar and eggs into the chocolate mixture, stirring gently but constantly with a rubber spatula so that the eggs don’t set from the heat.

7. Now whisk the remaining sugar and eggs until they are thick, pale, and doubled in volume, about 3 or 4 minutes.

8. Using the rubber spatula, delicately fold the whipped eggs into the chocolate mixture.

9. When the eggs are almost completely incorporated, gently fold in the dry ingredients.

10. Pour and scrape the batter in to an unbuttered 9-inch square pan.

11. Bake the brownies for 25-30 minuted

12. Cut into the center and they they should be just barely set and still pretty gooey.

13. Cool the brownies in the pan on a rack. Sprinkle with powdered sugar.
