Preheat the oven to 325°F. Lightly grease an 8 x 8 baking dish and line with parchment paper and set aside. Heat the oil in a pan gently, add the chocolate chips, and on low heat, stir till the chocolate is completely melted.

In a big enough bowl, combine the flour, cocoa powder, and salt.

Whisk together the eggs, water, sugar, and vanilla.

Add the melted chocolate mixture to the egg mixture. Mix well.

Now fold in the dry ingredients.

Bake for 40 minutes or until a toothpick comes out almost clean. It can be a little sticky. Cool completely before slicing.
