Equipment

9x13 baking dish

Ingredients

1 box white cake mix
3 large eggs
⅓ cup vegetable oil
1 cup milk
4-5 cups rhubarb cut in ½-inch chunks
1 cup strawberries diced
1 cup granulated sugar
1 small box Jell-O (Strawberry or Raspberry or Cherry) 3 ounces

Instructions

Preheat: Preheat your oven to 350℉.
Prepare the Cake Mix: Follow the directions on the box of cake mix. (Combine cake mix, milk, eggs, and oil in a large bowl. Blend on medium speed with an electric mixer for 2 minutes).
Pour into Pan: Pour the prepared cake batter into a greased 9x13-inch baking dish. Spread it out evenly.
Prepare the Fruit Topping: In a separate bowl, combine the sliced rhubarb, strawberries, sugar, and the package of Jell-O. Mix well to coat all the fruit.
Add Fruit Topping: Arrange the fruit mixture over the top of the cake batter. Do not mix it into the batter.
Bake: Bake the cake at 350℉ for 45-55 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. The fruit will sink to the bottom during baking.
Serve: Let the cake cool slightly before serving. Enjoy warm or cold with a scoop of vanilla ice cream or a dollop of whipped cream or Cool Whip.

Notes

This recipe is a fantastic way to use fresh, seasonal rhubarb and strawberries, but frozen fruit can also be used.
Feel free to experiment with different flavors of cake mix and Jello to find your favorite combination.
