Take two bowls. In one of them, mix flour, sugar, cocoa powder, chocolate chips and salt. In the other one, whisk eggs, olive oil and water.

Mix together all the ingredients in one bowl.

Preheat the oven to 170 degrees celcius/ 325 degrees fahrenheit.

Take a square metal dish (8x8) and put parchment paper in there. The mixture must be thick. Pour the mixture into the container and put in the oven for 40 minutes.

When cooked, wait for it to cool down fully before slicing. Sprinkle with some chocolate chips and you are all set! Enjoy!
