In another bowl whisk yolks, vanilla extract and 1 cup of sugar to a ribbon stage. Add a small amount of dry ingredients to the yolk mixture and alternate with a little of egg whites. Using a rubber spatula, continue folding until all ingredients are combined.
Bake at 375 degrees F on a greased half sheet tray or a cookie sheet lined with parchment and grease again. Bake approximately 12 to 14 minutes or until springy and toothpick is almost dry. Do not overbake.
In a blender combine above ingredients for approximately 1 minute or until smooth.

TO ASSEMBLE CAKE
Take cake and cut into two triangles then cut each in half laterally. On bottom half, ladle berry filling and evenly distribute. Then apply white chocolate berry sauce. You can at this point add fresh berry slices if desired.
Place top half back on top then place cake on a wire rack for glazing.
Using warm ganache ladle glaze on top of cake and allow to run down sides. If ganache is thin add another coat.
Place in refrigerator until glaze is solid. Take a whisk and splatter white chocolate sauce on top and decorate with more berries. With wings, they can garnish entire cake or you can use smaller wings to garnish each individual serving.
