Whisk eggs and sugar. Add oil. Mix in matzo cake meal and cocoa. Add nuts or use as a topping.
Bake in a greased 23cm x 33cm baking tin at 160 degrees C for 30 minutes. Check the brownies and return to the oven an additional 5 minutes if needed. The secret to moist brownies is to underbake them.
I put nuts on top rather than in the brownies for two reasons: They make the top look good without having to ice them and for those who don't or can't eat nuts, they are easily removed without having to search for them.
