How to get rid of five kilograms of flour in one week

One--Bake challah for Shabbat for our family
Two--Bake challah for my son's friend's family, who is hosting him for Shabbat
Three--Bake bread or rolls for the siyum that my son is hosting this week. A siyum is a celebration of the "completion" of the study of a tractate of the Mishnah or Talmud, or a book of the Torah. My son completed the Mishnah. I was hesitant about doing this so close to Pesach but I figure ten teenage boys means using up a lot of chametz.
Four--Bake cakes for the siyum and Shabbat
Five--Make quiche, pancakes, muffins?

All amounts are approximate, and we'll do the baking all at once, in a team. Am I the only one who spends more time cooking than cleaning this time of year?
