Greek Vasilopita

Step 1
Preheat oven to 325 degrees F (165 degrees C).

Step 2
In a large bowl, blend together the butter or margarine and the sugar. Separate 3 of the eggs; add the yolks and the 2 remaining whole eggs to the butter mixture. Stir in the vanilla and water.

Step 3
In another bowl, sift together the baking powder and flour. Add these dry ingredients to the creamed mixture.

Step 4
Whip 3 egg whites until they are foamy. Add 1 tablespoon sugar. Continue to whip the whites until they are stiff, but not dry. Fold whipped whites into batter.

Step 5
Pour the batter into a greased 10 x 4 inch tube pan. Wrap a large coin in foil, and place the coin in the batter. Press the coin down; it should be completely hidden. Sprinkle the nuts and seeds on top of the batter.

Step 6
Bake the cake for about 70 minutes, or until done. Cool on a wire rack.
