• 1/3 cup sliced almonds: Delivers crunchy, nutty highlights in the streusel.
• 1/2 cup all purpose flour: Binds the streusel crumbs for that perfect crumble.
• 1/3 cup brown sugar: Brings deep, caramelized sweetness to the almond streusel.

How To Make Creamy Rhubarb Dump Cake with Almond Streusel Topping

Creating this dessert is a breeze: you’ll layer tart rhubarb, a silken milk-cream blend, dry cake mix, and crunchy almond streusel all in one dish, then bake until golden and bubbly. The process is perfect for beginner bakers who want maximum flair with minimal prep—no fancy folding or piping required. Just follow these simple steps, and soon your kitchen will be filled with the cozy scent of warm rhubarb and toasted almonds.

1. Preheat the oven to 350°F and grease a 9x13-inch baking dish to prevent sticking.

2. In a medium bowl, combine chopped rhubarb, granulated sugar, cornstarch, and vanilla extract, tossing until every piece is evenly coated.

3. In another bowl, whisk together heavy cream and sweetened condensed milk until the mixture is smooth and lump-free.

4. Spread the rhubarb mixture evenly across the bottom of the prepared baking dish in a single layer.

5. Pour the creamy milk mixture over the rhubarb, making sure to cover it completely for a uniform custard.

6. Sprinkle the dry yellow cake mix evenly over the creamy rhubarb layer—do not stir, so it bakes into a cake-like topping.

7. In a separate bowl, stir together flour, brown sugar, sliced almonds, and salt, then cut in cold cubed butter with a pastry cutter or fork until the mixture forms coarse crumbs.

8. Scatter the almond streusel topping evenly over the cake mix layer for that signature crunch.

9. Bake for 45 to 50 minutes, or until the topping turns golden brown and the filling bubbles around the edges.

10. Allow the dump cake to cool in the pan for at least 15 minutes before serving to set the layers.

Frequently Asked Questions

Here are answers to the top questions about this creamy, crunchy one-pan dessert:

• How long does it take to prepare and bake the Creamy Rhubarb Dump Cake with Almond Streusel Topping?

Preparation takes about 15 minutes—chopping rhubarb, mixing the creamy and streusel components—and baking takes 45 to 50 minutes. Allow an additional 15 minutes for the cake to cool before serving.

• Can I use frozen rhubarb instead of fresh rhubarb?

Yes, you can use frozen chopped rhubarb. Thaw and drain any excess liquid before tossing it with sugar, cornstarch, and vanilla to prevent the dump cake from becoming too watery.

• How do I know when the dump cake is done?

The cake is ready when the almond streusel topping turns golden brown and the rhubarb filling is bubbling around the edges. If the topping browns too quickly, loosely tent the pan with foil and continue baking until the filling bubbles.

• Can I add lemon zest or juice for extra flavor?

Absolutely. Stir in one teaspoon of lemon zest or a squeeze of fresh lemon juice into the rhubarb mixture for added brightness. Be mindful that lemon juice can slightly increase the liquid content, so adjust cornstarch by another half teaspoon if needed.

• What are the best toppings or accompaniments for serving this cake?

This dump cake is delicious served warm with a scoop of vanilla ice cream or a dollop of freshly whipped cream. A light dusting of powdered sugar or a drizzle of sweetened condensed milk can also enhance its creamy tang.

• How should I store leftovers and how long will they keep?

Cover the cooled dump cake tightly with plastic wrap or foil and refrigerate for up to three days. Reheat individual portions in the microwave for about 20 seconds or place the pan in a 300°F oven for 10 to 15 minutes until warmed through.

• Can I make this dessert ahead of time or freeze it?

You can prepare the components up to the point of baking, cover the dish, and refrigerate overnight. When ready, bake as directed. For freezing, bake fully, cool completely, then wrap tightly and freeze for up to one month. Thaw in the refrigerator before reheating.
