Mayonnaise is the secret ingredient that replaces butter and makes these brownies rich and fudgy.

- Preheat oven to 350˚F (175˚C). Grease and line a 9" x 13" (23 cm x 33 cm) baking pan with parchment paper.
- Place the chopped chocolate in a large bowl and pour boiling water overtop. Let the chocolate mixture sit one minute, then whisk to melt.
- Whisk the sugar into the chocolate mixture and, then add the mayonnaise and the eggs, one at a time. Stir in the vanilla extract.
- Using a wooden spoon or spatula, stir in the flour, cocoa powder and salt until well blended. Stir in the chocolate chips.
