Instructions

Let’s dive into the steps to create this flavorful masterpiece:

Preheat Your Equipment: Preheat your oven to 350°F (175°C). This ensures your cake bakes evenly and gets that perfectly golden top.

Combine Ingredients: No mixing required here! Simply layer the chopped rhubarb in the bottom of your greased baking dish.

Prepare Your Cooking Vessel: Grease a 9×13-inch baking dish with butter or nonstick spray. This keeps the cake from sticking and makes cleanup easier.

Assemble the Dish: Sprinkle sugar evenly over the rhubarb, followed by the strawberry Jell-O. Then, pour the dry cake mix evenly on top. Finally, drizzle melted butter over the surface, making sure to cover as much of the cake mix as possible.

Cook to Perfection: Bake for 45–50 minutes, or until the top is golden brown and the fruit is bubbling around the edges. Your kitchen is going to smell amazing.

Finishing Touches: Let the cake cool for at least 10–15 minutes before serving. This gives the layers time to set and makes it easier to scoop.

Serve and Enjoy: Scoop into bowls and enjoy warm bonus points if you top it with whipped cream or vanilla ice cream!
