Double Layer Knox Blocks Recipe

In large heatproof bowl mix unflavored gelatin with jello. Add boiling water and stir until gelatin is completely dissolved-about a minute or so. Stir in whipping cream. Pour into a 9x13 in pan and chill until firm about four hours. The cream will rise during chilling to form layers. To serve, cut into squares or rectangles of desired shape and size for finger foods. Makes about 20-30 squares.
