Instructions
Preheat the oven to 350 degrees F. Line a 9x9-inch pan with foil, and spray with nonstick spray.
To a large bowl, add the melted butter and oil. Use a wooden spoon to stir in the sugar and cocoa powder until smooth.
Stir in the eggs, vanilla extract, espresso powder and salt. Then slowly mix in the flour. The batter will be thick. Stir in the chocolate chips.
Spread the batter into the prepared pan and top with a more chocolate chips.
Bake for 21 to 25 minutes or until the brownies just lose that glossy sheen around the edges and a toothpick inserted 1-inch from the edge comes out clean. Cool before cutting.
