Step-by-Step Instructions
Now, let’s dive into the magic of making this delightful rhubarb pudding cake. Don’t worry if you’re not an expert baker—these steps are easy to follow and will guide you through the process.
Step 1: Preheat Your Oven and Prepare the Baking Dish
Preheat your oven to 350°F (175°C). While the oven is warming up, grease an 8×8-inch baking dish or a similar-sized dish. You can use a bit of butter or cooking spray to make sure your cake doesn’t stick.
Step 2: Prepare the Rhubarb
Wash and chop the rhubarb into small 1/2-inch pieces. You’ll need about 2 cups. If you’ve never worked with fresh rhubarb before, remember that its stalks are the edible part. The leaves should be discarded as they contain toxins. Set the prepared rhubarb aside for later use.
Step 3: Mix the Dry Ingredients
In a medium-sized bowl, combine the flour, sugar, baking powder, salt, and cinnamon (if using). Mix them together using a whisk or spoon until well combined.
Step 4: Mix the Wet Ingredients
In a separate bowl, cream together the softened butter and granulated sugar until light and fluffy. You can use a hand mixer or beat by hand. Once combined, add the egg and vanilla extract, and beat until smooth.
Gradually add the dry ingredients to the wet mixture, alternating with the milk. Stir until the batter is smooth, but avoid over-mixing to maintain a soft texture.
Step 5: Add the Rhubarb
Gently fold the chopped rhubarb into the batter. You don’t need to mix it too much—just ensure the rhubarb is evenly distributed throughout.
Step 6: Add the Topping
Spoon the batter into the prepared baking dish. Then, sprinkle the brown sugar over the top. This sugar will create a lovely caramelized topping as it bakes.
Step 7: Pour the Boiling Water
The secret to the pudding-like texture lies in the next step. Carefully pour 1 cup of boiling water over the top of the cake batter. Do not stir—simply let the water sit on top. This will create the sauce at the bottom of the cake as it bakes.
Step 8: Bake and Enjoy
Place the dish in the preheated oven and bake for 40-45 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. The cake will rise and form a soft, pudding-like base with the rhubarb adding a tart contrast to the sweet sauce.
Once done, remove from the oven and allow the pudding cake to cool slightly before serving.

Common Mistakes to Avoid
While making rhubarb pudding cake is straightforward, there are a few common mistakes to watch out for:
- Using Old Rhubarb: Fresh rhubarb is key! Avoid using limp or dried-out rhubarb, as it can lead to a less flavorful dessert.
- Overmixing the Batter: Overmixing the batter can result in a dense cake. Mix just until the ingredients are incorporated.
- Skipping the Boiling Water: The water is essential for creating the pudding-like sauce underneath. Skipping this step will prevent the texture from being as intended.
- Not Letting It Cool: Give the pudding cake time to cool slightly before serving to allow the sauce to set.
By keeping these tips in mind, your rhubarb pudding cake will turn out perfect every time!
