Preheat the oven to 350. Lightly butter an 8x 8 pan. Set aside.

In a large mixing bowl, whisk together the cocoa, sugars, salt, and flour until evenly distributed.

Add the oil, water, and eggs, mixing until a glossy batter forms. Fold in the Toblerone bits

Scrape the mixture into the prepared pan, smoothing the top with the back of a spoon or spatula.

Bake for 35-40 minutes or until set and no longer shiny and "raw" looking.

Cool completely on a wire rack.

Slice into squares. Store leftovers in an airtight container for up to 4 days.
