Lemon-Orange Rainbow Poke Cake

1 lemon cake mixed (regular or pudding included)
1 pkg. (3 oz. size) orange flavored gelatin
1/2 c. orange juice or 1/2 c. cold water
1 c. boiling water

Prepare cake mix in the usual way. (Grease and flour 13-inch by 9-inch pan). Bake to 35 to 40 minutes at 350°. Cool cake in pan for 15 minutes. Prick with utility fork at 1/2 inch intervals. Meanwhile, dissolve gelatin in boiling water. Add orange juice and pour carefully over warm cake. Chill at least two hours. Garnish with white frosting and decorate with mandarin oranges or whatever looks pretty. (Mint green candies cut into slivers make an attractive “leaf look” with the mandarin oranges).
