How to Make Strawberry Rhubarb Dump Cake: Step-by-Step
Alright, let’s get down to business! Here’s how to make this ridiculously easy and delicious Strawberry Rhubarb Dump Cake.
- Preheat and Prep: Preheat your oven to 350°F (175°C). Make sure it’s nice and toasty!
- Rhubarb Base: Place the chopped rhubarb evenly in an ungreased 9″ x 13″ baking pan. We’re building the flavor foundation here!
- Sweeten the Deal: Mix the sugar and ground cinnamon (or a combo of ground cinnamon and nutmeg if you’re feeling fancy). Reserve about 1/4 cup of this sugary spice mix. Sprinkle the rest all over the rhubarb.
- Strawberry Sprinkle: Scatter the chopped strawberries over the rhubarb. Sprinkle with the remaining 1/4 cup of the sugar mixture.
- Gelatin Magic: Next, sprinkle the strawberry halal gelatin powder on top of the sugar mixture. This will add a lovely strawberry boost.
- Cake Mix Cloud: Sprinkle the cake mix on top of the halal gelatin powder. Make sure it’s evenly distributed for that perfect cakey topping.
- Butter Bliss: Distribute the sliced butter on top of the cake mix. This is what gives us that golden, buttery goodness.
- Water Pour: Slowly pour the water all over. This helps everything come together beautifully.
- Bake It Up: Bake in the preheated oven for 50-55 minutes, or until the top is set and browned, and the fruit mixture is bubbly around the edges. That’s how you know it’s ready!
- Cool and Serve: Allow the dump cake to cool for a few minutes before serving. This can even be baked a day ahead. Serve warmed up or at room temperature with a scoop of vanilla ice cream for extra indulgence.
Pro Tips for the Best Dump Cake Ever
Even though this recipe is super simple, here are a few extra tips to make sure your Strawberry Rhubarb Dump Cake is absolutely perfect:
- Even Distribution: Make sure the cake mix and butter are evenly distributed on top for a consistent texture and flavor.
- Don’t Overbake: Keep an eye on the cake while it’s baking. You want it to be golden brown, but not burnt.
- Let it Cool: Allowing the cake to cool slightly before serving helps the flavors meld together and prevents it from being too soggy.
- Use Fresh Ingredients: Fresh rhubarb and strawberries will give you the best flavor. If you can’t find fresh, frozen works too!
- Spice it Up: Experiment with different spices like nutmeg, ginger, or even a pinch of cardamom for a unique twist.
Common Mistakes to Avoid
We all make mistakes in the kitchen, but here are a few common pitfalls to watch out for when making this Strawberry Rhubarb Dump Cake:
- Uneven Baking: Make sure your oven is properly preheated and that the cake is placed in the center of the oven for even baking.
- Dry Cake Mix: If the cake mix seems dry, you can add a tablespoon or two of melted butter to the mix before sprinkling it on top.
- Soggy Bottom: To prevent a soggy bottom, make sure the rhubarb and strawberries are well-drained before adding them to the pan.
- Burning the Butter: Keep an eye on the butter while it’s baking. If it starts to brown too quickly, you can tent the cake with foil.
- Forgetting the Sugar: Don’t forget to sprinkle the sugar mixture over the rhubarb and strawberries! It’s what makes this cake so sweet and delicious.
Variations to Try
The beauty of a dump cake is its versatility! Here are a few variations to try:
- Rhubarb Cherry Dump Cake: Swap out the strawberries for cherries for a delicious twist.
- Apple Rhubarb Dump Cake: Add some chopped apples to the mix for a fall-inspired dessert.
- Peach Rhubarb Dump Cake: Peaches and rhubarb are a surprisingly delicious combination.
- Different Cake Mix Flavors: Experiment with different cake mix flavors like lemon, spice cake, or even chocolate.
- Add Nuts: Sprinkle some chopped nuts like pecans or walnuts on top for added crunch.

Got leftovers? Lucky you! Here’s how to store your Strawberry Rhubarb Dump Cake:
- Refrigerate: Store the cake in an airtight container in the refrigerator for up to 3-4 days.

- Reheating: Reheat the cake in the oven at 350°F (175°C) for about 10-15 minutes, or until warmed through. You can also microwave it in individual servings.
