Any type of berry could be used for the filling. Also I did not use the whipped cream that was an optional suggestion to fold into the filling. I cannot imagine adding it, because the filling already tastes like vanilla pudding. Adding whipped cream in my opinion would be too much. The cake is a vanilla base with meringue baked on top of it. Almonds were also added prior to baking.
