1 package (3 ounces) lime-flavored gelatin
1 cup hot water
1/2 cup fruit juice or water
1/2 cup drained crushed pineapple
1/4 cup chopped nuts
Few drops lemon juice
1 cup whipping cream
1/4 cup confectioner's sugar
Bake cake in two round layer pans as directed on the package. Cool. Dissolve gelatin in hot water. Add fruit juice and chill until almost firm. Add pineapple, nuts and lemon juice. Place two strips of aluminum foil across the bottom of each layer pan, letting strips extend over edge. Replace cake layers, placing one layer back in pan upside down and the other right side up. (This will make a better looking cake when gelatin layers are put together.)
Spoon the fruit gelatin over the two layers. Chill until firm. Whip cream with confectioner's sugar. Lift cake layers out of pans, using extended edges of foil. Stack layers gelatin side up. Frost sides with whipped cream. Refrigerate until serving time.
