Ward Christmas Party 2015
(serves 10)
1/2 cup flour
1/4 cup cocoa powder
1 tsp. baking powder
1/4 tsp. salt
4 eggs, separated
3/4 cup sugar, separated
1 tsp. vanilla
2 Tb. water
Grease a rimmed cookie sheet pan (10 x 15). Put parchment
paper over it and press the it to the pan, especially in the corners. In
a small bowl, combine flour, cocoa powder, baking powder and salt.
Carefully crack eggs and put the egg whites in a large bowl. Be
very careful to not get any yolk in the mixture or it won't rise when you beat
them. Put the egg yolks in another large bowl. With a hand mixer,
beat the egg whites until foamy. Continue beating and gradually add 1/2
cup sugar. Beat until it is stiff. Rinse the beaters and beat the
egg yolks until thick (about 3 minutes). Continue beating and slowly add
remaining 1/4 cup sugar. Add vanilla and beat again. Stir in water.
Gradually, fold flour mixture into egg yolk mixture. Fold in egg
whites. Pour into pan and spread the mixture so it covers the whole pan. Bake
at 350 degrees for 14 minutes. While it is baking, take a thin, flour
sack towel and evenly coat it with powdered sugar the same size as your cake.
The cake will not stick to the towel if there is powdered sugar on it.
When the cake is done, turn the pan upside down on to the powdered sugar
towel. Take off the parchment paper and roll up (with the towel) from the
short end and put it on a cooling rack. Let it completely cool until you
unroll it and are ready to put the filling on it.
Filling
2 egg whites
1/4 cup sugar
1/4 cup brown sugar
1 1/2 sticks butter, room temperature, cut into 1 Tb. increments
1/2 tsp. vanilla
pinch of salt
Put a cup or 2 of water in a pot. It should just cover a
little of the bottom of the pot. Bring it to a simmer. Carefully
crack the eggs and put the egg whites (reserve the yolks for another dessert)
in a pot that is smaller than the pot on the stove and nestle that pot on top
of the other one (like a double broiler). Add the sugars and whisk for 5
minutes so the sugar dissolves and it becomes warm. Immediately put the
mixture in a stand up mixer (with the whisk attachment )and beat it on low for
1 minute. Then increase the speed to high and mix for 9 more minutes.
It should fluff up. Take off the whisk attachment and put on a
paddle attachment. Turn the mixer on medium and add in 1 Tb. of butter at
a time. After adding it in, wait for 10 seconds and add the next one in.
Add the salt and vanilla and mix again.
Frosting
1/4 cup butter
1/4 cup cocoa
1 1/2 cups powdered sugar
1/8 tsp. salt
1 tsp. vanilla
1 1/2 Tb. milk
Put all the ingredients in a medium bowl and beat with a hand
mixer.
Unroll the cake. Spread the filling over all of it.
Roll it up again, put it on a serving platter and frost it.
Refrigerate.
