"An absolute winner with everyone!! Only used 4 tablespoons of icing sugar, and still very sweet. Delicious!" ⭐⭐⭐⭐⭐
I got this recipe from my Auntie Sue (she'd had it forever), and my first thought was, "Where have you been all my life?!" Granted, I am a bit crazy about rhubarb, but this is truly one of those old-timey gems!
🥘Ingredient Notes
For this baked sticky rhubarb pudding recipe, you'll need:

- Rhubarb. You can use fresh or frozen. *If you use frozen rhubarb, just make sure you defrost it completely and drain it, but don't squeeze the liquid out. * I used frozen rhubarb for this recipe.
- Milk. I use 1% because it's what I have on hand, but you can use any milk.
- Unsalted butter. I use unsalted butter in my baking so I can control the salt. The salt content in salted butter varies by brand.
- Powdered sugar/icing sugar. The use of powdered sugar gives this pudding a unique taste.
- Cornstarch. Cornstarch thickens this pudding, but you could also use Minute Tapioca.

Expert Recipe Tips
- Use Fresh or Frozen Rhubarb Correctly. If using fresh rhubarb, make sure to wash and trim the ends before chopping.. If using frozen rhubarb, thaw it completely and drain excess liquid, but don’t squeeze out the moisture—it helps create the perfect pudding consistency.
- Don’t Overmix the Batter. Mix the batter until it is just combined. Overmixing can lead to a denser texture instead of a light, pudding-like cake.
- The Magic of the Water Layer. Pour the water over the batter without stirring it in. This step creates the pudding-like sauce at the bottom as it bakes.
- Baking Time May Vary. Oven temperatures can vary, so check your pudding at the 50-minute mark by inserting a toothpick into the cake portion. If it comes out clean, it’s done! If the top is browning too quickly, loosely cover it with foil for the last 15 minutes of baking.
- Let It Rest Before Serving. Allow the pudding to cool for at least 10 minutes after baking. This helps the sauce thicken slightly and enhances the flavor.
- Want a Richer Caramel Flavor? Swap out white sugar for brown sugar to add depth and a slight caramel taste to the dish.
