Ingredients You’ll Need
This Rhubarb Pudding Cake Recipe uses a small list of simple ingredients that come together beautifully to create its unique texture and flavor. Each component plays a crucial role, from that tangy rhubarb to the rich moistness added by butter and vanilla.
- Chopped fresh rhubarb (3 cups, about 400g): The star ingredient, providing tartness and a lovely red hue.
- Granulated sugar (¾ cup, 150g): Sprinkled over rhubarb to sweeten and soften it as it bakes.
- All-purpose flour (1 cup, 125g): Forms the cake base, giving structure without heaviness.
- Brown sugar, packed (¾ cup, 150g): Adds a deep sweetness and enhances the cake’s moistness.
- Baking powder (2 teaspoons): Helps the cake rise into a tender, fluffy layer.
- Salt (¼ teaspoon): Balances the flavors and enhances sweetness.
- Milk (½ cup, 120ml): Moistens the batter, contributing to the pudding texture beneath.
- Melted unsalted butter (¼ cup, 60g): Brings richness and a tender crumb.
- Vanilla extract (1 teaspoon): Adds warmth and depth to the cake.
- Boiling water (1 cup, 240ml): Poured on top to create the pudding layer without stirring.
How to Make Rhubarb Pudding Cake Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 350°F (175°C). Lightly grease a 9-inch square baking dish to ensure your pudding cake doesn’t stick and comes out beautifully when baked.
Step 2: Layer the Rhubarb and Sugar
Spread the chopped rhubarb evenly in the bottom of your prepared baking dish. Sprinkle the granulated sugar over the rhubarb but resist the urge to stir it in—this separation is key to creating that wonderful pudding effect beneath the cake.
Step 3: Mix Dry Ingredients for the Cake Batter
In a medium bowl, whisk together the all-purpose flour, packed brown sugar, baking powder, and salt. Combining these dry ingredients ensures your cake turns out tender and well-risen.
Step 4: Add Wet Ingredients and Stir Until Smooth
Pour in the milk, melted butter, and vanilla extract to the dry mixture. Stir gently but thoroughly until you have a smooth batter free of lumps—this will be the cake topping to your rhubarb layer.
Step 5: Assemble the Cake Layer Over Rhubarb
Spoon the batter over the rhubarb and carefully spread it out evenly, covering all the fruit. Don’t stir — the layers need to stay separate to form that signature pudding texture below.
Step 6: Add Boiling Water Without Stirring
Slowly pour the boiling water over the top of the batter. This step might feel a little unusual, but it’s essential—as the cake bakes, the hot water will interact with the sugar and rhubarb underneath, creating that irresistible pudding layer.
Step 7: Bake Until Golden and Bubbling
Place the dish in your hot oven and bake for 45 to 50 minutes. When the top looks golden and the pudding bubbles at the edges, you’ll know it’s ready. The contrast between the crisp cake top and the saucy bottom will make you so excited to dig in!
Step 8: Cool Briefly Before Serving
Let the pudding cake cool for 10 to 15 minutes after removing it from the oven. This waiting time helps everything set slightly, making it easier to serve and even more enjoyable to eat.

FAQs
Can I use frozen rhubarb for this Rhubarb Pudding Cake Recipe?
Absolutely! Just thaw and drain the frozen rhubarb well to avoid excess moisture. Using frozen rhubarb is a convenient way to enjoy this dessert year-round.
Is it possible to make this recipe gluten-free?
Yes, replace the all-purpose flour with a gluten-free baking blend that includes xanthan gum to maintain structure. The texture might vary slightly, but it will still be delicious.
Why do I pour boiling water on top of the batter?
This technique helps the sugar and rhubarb dissolve and settle beneath the cake batter during baking, creating the signature pudding layer that sets this recipe apart from a regular cake.
Can I substitute the brown sugar with white sugar?
While you can, brown sugar adds a richer flavor and moisture to the cake. Substituting it with white sugar will yield a slightly different taste and texture, but the cake will still turn out tasty.
How do I know when the pudding cake is done baking?
Look for a golden-brown cake top and bubbling edges around the pudding layer. Inserting a toothpick into the cake layer should come out mostly clean, with maybe just a few moist crumbs.
