The Diner Finder is the Internet’s best source of real diner information.This recipe comes to us from one of our favorite diners, the Highland Park in Rochester, NY. We’ve had several opportunities to visit this one-of-a-kind Orleans diner in the past 5 months, and we’re happy to say that the apple pie is still about the best there is. And just about every other meal we’ve had there sets the standard in diner fare.
Place berries in two different sauce pans. Add 1⁄4 cup of the sugar to the blueberries and 1⁄2 cup to the raspberries. Simmer for one hour, until very thick, cool, then chill in the refrigerator.
Melt the white chocolate in a double boiler. Meanwhile, using an electric mixer, beat the butter in a large bowl until light. Gradually add in cream cheese until just combined. Beat in both extracts, add the powdered sugar, and beat until smooth. Add the melted chocolate, and beat until just combined. Stir in the sour cream. Chill until spreadable.
Cream the butter and sugar. Sift the cake flour before measuring. Re-sift twice with the salt and baking powder. Add the flour mixture to the butter-sugar mixture, alternating with milk. Beat until smooth after each addition. Add the extracts. Beat the egg whites until stiff but not dry, then fold them lightly into the cake batter. Pour into three 8-inch greased round cake pans. Bake at 325° for 40 minutes, or until cake tests done. Cool on wire racks.
Cut each cake in half horizontally, for a total of six thin pieces. Spread the first layer with a thin layer of frosting, then half the chilled raspberries. Frost each of the remaining layers. Leave every second layer without berries; add blueberries to the third layer and raspberries to the fifth. Use the remaining frosting for the sides and top. Chill for one hour.
Slice into 16 thin slices.
