Steps

Preheat oven to 350 degrees F (177 C) and lightly grease a 9x13 baking dish.

Combine the melted butter, sugar, and vanilla in a large bowl.

Beat in the eggs, one at a time, mixing well after each, until thoroughly blended.

Sift the flour, cocoa powder, and salt in a bowl.

Gradually stir flour mixture into the egg mixture until blended.

Stir in 1 cup of chocolate chips.

Spread the batter evenly into the prepared baking dish.

Cover with remaining 1 cup of chocolate chips.

Bake in preheated oven until an inserted toothpick comes out clean, 35 to 40 minutes.
