Preheat your oven to 350°F (175°C) and lightly grease a 9x13-inch baking dish.
Wash the rhubarb and cut it into 1/2-inch pieces. Hull and slice the strawberries. Set both aside.
In a bowl, prepare the cake mix according to the package instructions, using water, eggs, and vegetable oil. Mix until smooth and pour the batter evenly into the prepared baking dish.
In another bowl, combine the rhubarb, strawberries, and granulated sugar. Mix well and spread the fruit mixture evenly over the cake batter in the baking dish.
Sprinkle the strawberry Jell-O powder evenly over the top of the fruit layer.
Cube the unsalted butter and distribute the cubes evenly across the surface of the cake.
Bake in the preheated oven for 50-55 minutes, or until the cake is golden brown and a toothpick inserted in the center comes out clean.
Allow the cake to cool for at least 15 minutes before serving. Optional: Dust with powdered sugar for garnish.
Slice into squares and enjoy warm or at room temperature.
