1-First: preheat the oven to 325°F and lightly spray an 8×8 inch baking pan with oil, then line it with parchment paper and spray the paper again for easy removal.

2-In a medium bowl, combine the granulated sugar, flour, cocoa powder, powdered sugar, chocolate chips, and salt to mix the dry ingredients thoroughly.

3-Next, in a large bowl, whisk together the eggs, oil, water, and vanilla extract until well blended.

4-Now, sprinkle the dry mixture over the wet mixture and fold it together until just combined; the batter will be thick, so don’t overmix.

5-Pour the batter into the prepared pan and use a spatula to spread it evenly and smooth the top for even baking.

6-Bake for 40 to 48 minutes, until a toothpick inserted comes out with a few crumbs attached, then cool completely before slicing and serving to achieve that gooey texture.
