Ingredients You’ll Need
This Rhubarb Pudding Cake Recipe uses straightforward, pantry-friendly ingredients that come together to create a remarkable harmony of flavors and textures. Each element plays a vital role, from the tangy rhubarb that gives brightness to the rich, buttery topping that adds warmth and softness.
- Chopped fresh rhubarb: The star ingredient brings a beautiful tartness and vibrant color to the cake.
- Granulated sugar: Sprinkled on rhubarb, it helps sweeten and soften its natural tang.
- All-purpose flour: Forms the base of the cake batter, providing structure and tenderness.
- Packed brown sugar: Adds a deep, molasses flavor and moisture to the cake layer.
- Baking powder: Ensures the cake rises nicely and stays light.
- Salt: Enhances all the flavors and balances the sweetness.
- Milk: Keeps the batter smooth, rich, and moist.
- Melted unsalted butter: Contributes a creamy, velvety richness to the cake topping.
- Vanilla extract: A warm flavor boost that complements the rhubarb’s tartness.
- Boiling water: Poured on top before baking, it creates the magic of pudding beneath the cake layer.
How to Make Rhubarb Pudding Cake Recipe
Step 1: Prepare Your Oven and Baking Dish
Begin by preheating your oven to 350°F (175°C). Lightly grease a 9-inch square baking dish to ensure your pudding cake releases easily after baking without losing any of that lovely crust.
Step 2: Layer the Rhubarb and Sugar
Spread the chopped rhubarb evenly across the bottom of the prepared dish and sprinkle granulated sugar over the top. Resist the temptation to stir; this step allows the rhubarb to release juices naturally as it bakes, creating a perfect syrupy base.
Step 3: Mix the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, packed brown sugar, baking powder, and salt. This dry mixture will form the foundation of the cake layer and delivers both sweetness and structure.
Step 4: Add the Wet Ingredients
Add milk, melted butter, and vanilla extract to the dry ingredients, stirring gently until you get a smooth batter. This batter will sit on top of the rhubarb and transform into a tender cake during baking.
Step 5: Spoon Batter Over Rhubarb
Carefully spoon the cake batter over the rhubarb without stirring. Gently spread it evenly across the surface, so it fully covers the fruit. Keeping the layers separate ensures a distinct cake top and pudding base after baking.
Step 6: Pour Boiling Water on Top
Slowly and carefully pour the boiling water evenly over the batter layer. Do not stir at this point. This step might feel unusual, but the hot water will seep down during baking, resulting in the signature pudding texture beneath the cake.
Step 7: Bake Until Golden and Bubbling
Bake your Rhubarb Pudding Cake Recipe for 45 to 50 minutes, or until the top is golden and the pudding bubbles at the edges. This visual cue signals that everything is cooked through and perfectly melded.
Step 8: Cool Before Serving
Allow the cake to cool for 10 to 15 minutes. This resting time helps the pudding set and makes it easier to serve while enhancing the flavors.
How to Serve Rhubarb Pudding Cake Recipe

Garnishes
This pudding cake is so delicious on its own, but you can elevate it with a scoop of vanilla ice cream, a dollop of whipped cream, or a light dusting of powdered sugar. Fresh mint leaves can add a refreshing visual and aromatic touch as well.
Side Dishes
Consider pairing this Rhubarb Pudding Cake Recipe with a simple cup of tea or coffee to complement its sweetness and tartness. Fresh fruit salad or lightly sweetened yogurt also make wonderful accompaniments to balance the richness and add texture contrast.
Creative Ways to Present
For a charming presentation, serve the pudding cake in individual ramekins straight from the oven, offering guests their own warm, personal dessert. Alternatively, layering the cake in clear glass dishes can showcase the lovely contrast between the rhubarb syrup and cakey top.
Make Ahead and Storage
Storing Leftovers

Reheating

FAQs
Can I use frozen rhubarb for this recipe?
Yes! Frozen rhubarb works well in this pudding cake. Just make sure to thaw and drain any excess liquid to prevent the dessert from becoming too watery.
Is it possible to make this cake gluten-free?
Absolutely. Substitute the all-purpose flour with a gluten-free baking blend that includes xanthan gum for best results, and ensure all other ingredients are gluten-free certified.
Why do I pour boiling water over the batter?
The boiling water helps the rhubarb juices meld with the batter as it bakes, creating a unique pudding layer underneath the cake topping that adds to the dessert’s moist, luscious texture.
Can I substitute the sugar with a natural sweetener?
You can try using honey or maple syrup in place of sugar, but know they will alter the texture slightly and add their own distinctive flavors. Adjust sweetness to taste and reduce other liquids accordingly.
What is the best way to serve this dessert warm or cold?
Rhubarb Pudding Cake Recipe is delicious served warm to appreciate the pudding texture and fresh flavor, but it’s also lovely chilled when the flavors have melded further and the cake firms up.
