Pre-heat the oven at 375F.
In a large bowl or a stand mixer beat the 8 eggs very well.
Add the olive oil and beat well.
Add the baking powder and lemon zest... mix well.
Add the sugar and mix well.
Add the flour all at once and let it mix completely for a few minutes.
The mix will be rather soft.
Put a little flour in the palm of your hand.
Take a spoonful of dough and drap it in the palm over the flour. Put some flour in the palm of the other hand as well and roll the dough into a ball. Drop it on the baking pan and flatten the ball with the palm of your hand.
Finish rolling all your cookies.
Beat the other two eggs and brush each cookie with the egg wash. Finish with some sugar sprinkles.
Bake at 375F for 20 Mins.
