Ingredients You’ll Need

4 cups fresh rhubarb: Choose fresh, vibrant stalks for the best flavor and texture. Frozen rhubarb can be used but will yield a softer result.
1 cup strawberry jelly: Opt for jelly instead of jam for a smoother consistency that blends seamlessly with the rhubarb.
½ cup salted butter: Softened to room temperature for easy mixing and a rich flavor. You could use unsalted butter, but you may want to add a pinch of salt.
15.25 oz. box yellow cake mix: A classic, moist choice that perfectly complements the fruity layers. You could also use a gluten-free cake mix for a dietary alternative.

How to Make Strawberry Rhubarb Dump Cake

Prepare your crockpot: Start by spraying the liner of your crockpot with nonstick spray to prevent sticking and make cleanup a breeze.
Add the filling: Combine the fresh rhubarb and strawberry jelly in the basin of your crockpot. Stir gently to make sure every piece of rhubarb is coated with the jelly—this will help develop that delicious, fruity sauce.
Make the crumble topping: In a large bowl, mix the yellow cake mix with the softened butter. Using a fork or your fingers, work the butter into the cake mix until it looks like damp sand. This texture is key for achieving that lovely topping.
Top the filling with the crumble: Evenly sprinkle your cake mixture over the rhubarb. Make sure it covers all the jelly—it’ll keep the filling from bubbling up too much.
Cover and cook: Pop the lid on and cook on high for about 2 hours. You’ll know it’s done when the crust is golden brown and the filling is bubbling around the edges. If it’s still pale after two hours, keep cooking for another hour or until it reaches that beautiful golden hue.

Storing & Reheating

Once your Strawberry Rhubarb Dump Cake has cooled, you can store it at room temperature for up to 2 days. For longer storage, refrigerate in an airtight container for up to a week. It also freezes well; just wrap it tightly after it’s completely cooled and keep it in the freezer for up to 3 months. When you’re ready to dig in, simply reheat in the microwave for about 30 seconds; keep in mind that the texture might soften a bit, but a scoop of vanilla ice cream will work wonders to refresh your dessert.

Chef’s Helpful Tips

Make sure to soften your butter adequately; cold butter won’t incorporate well into the cake mix and could result in lumps.
For a more pronounced flavor, consider adding a dash of vanilla extract or a sprinkle of cinnamon to the crumble mix.
If your toppings seem a bit wet or uneven after cooking, don’t hesitate to let them cook for a bit longer—patience pays off!
If you’d like a thicker filling, you can add a tablespoon of cornstarch to the rhubarb and jelly mixture to help thicken it up, especially if your rhubarb is extra juicy.

If you’re looking for a dessert that evokes the flavors of summer while being super simple to make, Strawberry Rhubarb Dump Cake is where it’s at. It’s versatile, comforting, and has that homemade touch that takes your taste buds on a delightful journey. So gather your ingredients and let’s get baking!

Recipe FAQs

Can I use frozen rhubarb instead of fresh?

Yes, you can use frozen rhubarb, but keep in mind that it may result in a softer texture. If using frozen, you don’t need to thaw it beforehand; just add it directly to the crockpot with the jelly.

How do I know when the cake is done cooking?

Your dump cake should have a golden brown topping and the filling should be bubbly—look for bubbling around the edges of the crockpot. If the topping still appears gooey, let it cook longer until it firms up and turns golden.

Can I make this dessert ahead of time?

Absolutely! You can prep the rhubarb and jelly mixture the night before and store it in the fridge. Just mix the crumble topping when you’re ready to cook. It’s a great way to save time on busy days!

What should I serve with Strawberry Rhubarb Dump Cake?

It’s delightful on its own, but pairing it with a scoop of vanilla ice cream or a dollop of whipped cream elevates it to another level of deliciousness. Fresh strawberries or mint leaves can also add a nice garnish for an extra pop of color and flavor.
