Melt together butter and 3/4 cup chocolate chips. Set aside and let
cool. Mix together 10 tbls sugar, 4 egg yolks, and 2 tbls flour. Make
sure this is well mixed, add the chocolate mixture when it is cooled.
Mix well.
Beat egg whites until stiff, and fold into the chocolate mixture.
Blend well, but gently. Spread batter evenly into a 9x13" pan. Bake
at 350 for 18 minutes. This will puff up and then fall when removed
from the oven. When cool, spread with a THIN layer of Raspberry
preserves.
Whipped Cream Layer: Beat 1 pint cream with 1 Tbls of sugar, until
stiff. Spread evenly on cooled cake.
Refrigerate.
GLAZE: Melt together heavy cream, instant coffee and chocolate chips.
When this mixture is melted and well blended, take off of heat and
let cool. Stir well and pour on top of whipped cream layer of cake.
Tilt the pan so the glaze distributes evenly over the cream.
