3 C. - Chopped Rhubarb
½ C. - White Sugar
½ C. - Brown Sugar
1 - (3 oz.) Box - Strawberry Jell-o Mix
2 C. - Mini Marshmallows
1 - (18.25 oz.) Box - White or Yellow Cake Mix
In a medium bowl, mix together the pineapple, rhubarb, white sugar, brown sugar, jell-o, and marshmallows. Pour into the bottom of a sprayed 13x9 cake pan. In another bowl make the cake according to the box directions but replace the water with the pineapple juice, when mixed spread evenly over the rhubarb mixture. Bake in a 350 degree oven for 45 min to an hour or until a tooth pick comes out clean. You can either turn the cake out onto a serving plate while it is still warm or as I did just cut out a piece and invert it onto a dessert plate.
