Ingredients for Prune Mui Recipe Hawaii

Sweet plums meet warm spices in this island-inspired steamed pudding. Simple yet unforgettable.

The prunes are everything here. Look for plump, moist ones—dry, shriveled prunes won’t soften right. I grab mine at Whole Foods or any well-stocked grocery store. The flour doesn’t need to be anything fancy—just standard all-purpose. For the spices, Penzeys has amazing cinnamon and ginger if you want to level up. The vanilla? Always pure extract, never imitation.

No prunes? Dried plums work the same (they’re literally the same thing). Out of all-purpose flour? Cake flour at a 1:1 ratio keeps it tender. Need to skip eggs? Flax eggs (1 tbsp ground flax + 3 tbsp water per egg) bind surprisingly well here. The sugar can be brown instead of granulated for a deeper flavor (pack it if you go that route).

Batter keeps in the fridge 1 day if you need to prep ahead. The steamed pudding stores beautifully for 4-5 days—just keep it covered. Freezes for 3 months too, though it’s so good fresh you probably won’t need to.

Step-by-Step Instructions for Sweet Steamed Plum Pudding

Here’s how I make this Hawaiian favorite with perfect texture every time.

Step 1: Prepare the Prunes and Wet Ingredients

First, I chop the 1.5 cups prunes into small, even pieces—this ensures they distribute nicely in every bite. The finer the chop, the more uniform your pudding will be. Place them in a large mixing bowl.

To the same bowl, add the 2 whole large eggs (already beaten), 0.75 cup granulated sugar, 0.25 cup vegetable oil, and 1 tsp vanilla extract. Whisk these together until the mixture is smooth and the sugar begins to dissolve slightly. The sugar should look mostly incorporated, not grainy.

Step 2: Combine Dry Ingredients and Create the Batter

In a separate bowl, I sift together the 1 cup all-purpose flour, 1 tsp baking soda, 1 tsp ground cinnamon, 0.5 tsp ground ginger, and 0.25 tsp salt. Sifting is key here—it breaks up any lumps in the flour and baking soda, giving your pudding that light, airy texture.

Gradually fold the dry ingredients into the wet mixture, stirring just until combined. Don’t overmix—you want a smooth batter but a few small lumps are fine. Finally, stir in the 1 tsp lemon zest and the chopped prunes. The batter will be thick but pourable.

Step 3: Add Hot Water and Prepare for Steaming

Now, carefully pour in the 1 cup hot water while stirring continuously. This step is crucial—the hot water activates the baking soda, which gives the pudding its rise and tender crumb. The batter will thin slightly but should still be thick enough to hold its shape.

Pour the batter into a greased heatproof dish or individual ramekins. I like to use a 9-inch round cake pan for this recipe. Tap the dish gently on the counter to remove any air bubbles—this helps prevent large holes in the finished pudding.

Step 4: Steam to Perfection

Place your dish in a steamer basket set over a pot of simmering water. Make sure the water doesn’t touch the bottom of the dish. Cover tightly with a lid to trap the steam. Steam for 45-50 minutes until the pudding is set and a toothpick inserted in the center comes out clean.

Check the water level occasionally and add more hot water if needed. You’ll know it’s done when the top springs back lightly when touched and the edges pull away slightly from the sides of the dish. The pudding should have a golden-brown color and a moist, springy texture.

Step 5: Cool and Serve

Remove the pudding from the steamer and let it cool in the dish for 10 minutes. This rest period helps it set further and makes it easier to slice. Then, turn it out onto a serving plate or serve directly from the dish.

I like to serve this warm or at room temperature. It pairs beautifully with a scoop of vanilla ice cream or a drizzle of caramel sauce. The flavors deepen as it sits, so leftovers (if you have any) taste even better the next day.

Troubleshooting This Recipe

Batter Too Thin

If your batter looks watery after adding the hot water, you may have added too much liquid. Stir in an additional 1-2 tbsp all-purpose flour until it reaches a thick, pourable consistency. The batter should coat the back of a spoon but still drip slowly.

Pudding Not Rising

This usually means your baking soda is old or the hot water wasn’t hot enough. Always use fresh baking soda and ensure the water is at least 180°F when added. Also, make sure your steamer is tightly covered to trap steam effectively.

Dense Texture

Overmixing the batter develops too much gluten, leading to a dense pudding. Stir just until the dry ingredients are incorporated. If you’ve already overmixed, try folding in 1 whipped egg white at the end to lighten the texture.

Uneven Cooking

If the center is undercooked while the edges are done, your steamer may not be distributing heat evenly. Use a bamboo steamer with a tight lid and ensure the water level stays consistent. Rotate the dish halfway through cooking for even results. 💡

Prunes Sinking

To prevent prunes from sinking to the bottom, toss them in 1 tbsp flour before folding into the batter. This helps them suspend evenly. Also, let the batter rest for 5 minutes before steaming to allow it to thicken slightly.

Bitter Aftertaste

This can happen if the baking soda isn’t fully incorporated. Ensure it’s well mixed with the flour before combining with wet ingredients. If it’s too late, a drizzle of honey or caramel when serving can balance the bitterness.
