      • 5 cups diced rhubarb (½-inch pieces)

      Notes

      **Recipe Notes:**

      * ✅ *Fresh or frozen rhubarb* works great! If using frozen, reduce water to ½ cup to prevent sogginess.
      * ✅ *Do not stir!* That’s the magic of a dump cake—the layers bake into a cobbler-like perfection.
      * ✅ *Flavor twist:* Try orange gelatin for a citrusy spin, or top with chopped pecans before baking for crunch.

      **Bonus Tip:**.

      This is a great make-ahead dessert—store leftovers in the fridge and reheat in the microwave for 30 seconds to enjoy warm. Tastes even better the next day as the flavors meld together

      Recipe Size Alteration Note

      This one was one of our favorites when we lived in Maine, getting fresh rhubarb in the South isn’t as easy as it was up North, haha. This is extremely good with strawberry jello, although I’m sure the raspberry is delicious as well. For a Slight change of pace you can substitute 1/2 c. honey for the sugar or omit the sugar all together since it has the jello in it.
