To make the cake:
Sift flour once and then measure.
Combine baking powder, salt, and eggs in a bowl.
Beat with mixer, adding sugar gradually, until mixture becomes thick and light-colored.
Gradually fold in flour.
Mix in 1 tsp. vanilla.
Turn into a 10 by 15 pan lined with parchment paper.
Bake at 400° for 13 minutes.
Turn cake onto a cloth which has been sprinkled with powdered sugar.
Remove the paper and cut off the crisp edges of the cake.
Allow cake to cool.
Once cooled, cut into 4 equal parts.
Now slice each part horizontally down the middle so you have 8 thin layers.

To make the frosting:
Melt chocolate and butter together.
Add sugar, milk, egg whites, and 1 tsp. vanilla.
Mix well.
Place in an ice bath and beat until it is a spreadable consistency.

Put it all together:
Spread a thin layer of frosting, about 1/4 cup, on a layer of cake.
Place another layer of cake on top of that and repeat the process.
Continue repeating this process until all 8 layers are done.
Frost the top and sides of the torte with the remaining frosting.
Chill well before serving.
