The official Kookie Cake recipe

After three attempts at baking cakes that include couscous (the first one tasted great but was too sandy. The second was too bland and dry, the third a little too dense and didn't rise), we'd run out of time to experiment before the big women's day event in Fes. So what could I do but piece together what I'd learned from the three previous trials, throw in some new random ingredients just for fun, quadruple the recipe to fill a huge sheet cake pan, and cart it off to the public oven, positive that the fourth time was going to be the charm. And it was. I think it turned out shockingly good, considering how terrible I'd recently proven myself to be at recipe creation. Here's the recipe. I've named it the official Kookie cake because all of the interesting ingredients (couscous, olive oil, carrots, apples and almonds) are grown or produced in the village.
6 eggs
2 cups sugar
2 cups mild olive oil
4 cups flour
2 packages of baking powder (2 tsp maybe?)
3 packages of vanilla sugar (1.5 tsp vanilla extract maybe?)
a pinch or two of salt
2 large apples, peeled and grated
3 cups shredded carrots
1 cup dry El Karma hand-rolled couscous, boiled in water until it softens and loses its uncooked-flour smell (or steamed if you have time to kill)
3 cups almonds, crushed (sprinkle on top of batter before you bake it)
