Preheat oven to 325°F and start a pot of boiling water on the stove.
In a small bowl, mix flour and cocoa.
Whisk 6 egg yolks into the chocolate mixture.
Then, add flour mixture to the chocolate and stir well.
Pour the cake batter into the lined and greased 9 x 9 pan, using a spatula to level the top.
Bake for 60 minutes or until a toothpick inserted in the center comes out clean.
Immediately lift the cake out of the pan using the “handles” of parchment paper.
Then, while the cake is still hot, drop some dark chocolate chips on top.
